- A testicular tumor in a 12-year-old boy proved to be a carcinoid tumor. An extensive investigation including a computed tomographic scan of the abdominal and pelvic region as well as both 123I-labeled metaiodobenzylguanidine and 111In-coupled octreotide scintigraphy was normal. Because histopathologic examination of the primary surgical specimen revealed tumor growth in the resection border of the spermatic vessels, a second operation with unilateral lymph node dissection was performed. Surprisingly, 3 lymph node metastases were found. No further treatment was given and the boy is alive without disease 9 years after surgery. This case illustrates that modern scintigraphic techniques do not always detect carcinoid tumors. Because carcinoids respond poorly to other treatment modalities, the importance of initial radical surgery including a meticulous examination of regional lymph nodes is emphasized.

-
In: Journal of Pediatric Surgery. - : Elsevier BV. - 0022-3468 .- 1531-5037. ; 55:11, s. 2419-2424
-
Journal article (peer-reviewed)abstract
- BackgroundThe aims of this study were to compare the incidence of small bowel obstruction (SBO) requiring laparotomy after laparoscopic appendectomy (LA) and open appendectomy (OA) in children and to identify risk factors for SBO.MethodsMedical records of patients who underwent appendectomy from 2000 to 2014 at our department of Pediatric Surgery were reviewed. Risk factors were analyzed using Cox proportional hazard regression.ResultsTotally 619 out of 840 patients were included. OA was performed in 474 (76.6%), LA in 130 patients (21%), and 15 (2.4%) were converted from LA to OA. Age, sex and proportion of perforated appendicitis were comparable in the LA and OA groups. Median follow-up time was 11.4 years (2.6–18.4). The incidence of SBO after LA was 1.5%, after OA 1.9% and in the converted group 6.7% (p = 0.3650). There were no significant differences in the incidence of postoperative intraabdominal abscess, wound infection or length of stay between LA and OA. Perforation and postoperative intra-abdominal abscess were identified as risk factors with 9.03 (p < 0.001) and 6.98 (p = 0.004) times higher risk of SBO, respectively.ConclusionsThe risk for SBO after appendectomy in children was significantly related to perforated appendicitis and postoperative intra-abdominal abscess and not to the surgical approach.Level of EvidenceLevel III.

Resorbable Bioscaffold for Esophageal Repair in a Dog Model
- 2000
-
In: Journal of Pediatric Surgery. - : Elsevier BV. - 0022-3468 .- 1531-5037. ; 35:7, s. 1097-1103
-
Journal article (peer-reviewed)abstract
- Purpose: Porcine-derived, xenogeneic extracellular matrix (ECM) derived from either the small intestinal submucosa (SIS) or urinary bladder submucosa (UBS) was used as a tissue scaffold for esophageal repair in a dog model. Methods: Patch defects measuring approximately 5 cm in length and encompassing 40% to 50% of the circumference of the esophagus or complete circumferential segmental defects measuring 5 cm in length were created by surgical resection in healthy adult female dogs. The defects were repaired with ECM scaffolds derived from either SIS or UBS. The animals were kept alive for periods ranging from 4 days to 15 months. Results: The xenogeneic scaffolds used for repair of the patch defects were resorbed completely within 30 to 60 days and showed replacement by skeletal muscle, which was oriented appropriately and contiguous with adjacent normal esophageal skeletal muscle, organized collagenous connective tissue, and a complete and intact squamous epithelium. No signs of clinical esophageal dysfunction were seen in any of the animals with the patch defect repair. The xenogeneic scaffolds configured into tubes for repair of the segmental defects all showed stricture within 45 days of surgery. Conclusion: These ECMs show promise as a treatment option for esophageal repair, but stricture remains problematic for complete tube grafts.

A Nordic multicenter survey of long-term bowel function after transanal endorectal pull-through in 200 patients with rectosigmoid Hirschsprung disease
- 2017
-
In: Journal of Pediatric Surgery. - : Elsevier BV. - 1531-5037 .- 0022-3468. ; 52:9, s. 1458-1464
-
Journal article (peer-reviewed)abstract
- OBJECTIVE: Transanal endorectal pull-through (ERPT) is the most popular technique to treat Hirschsprung disease (HD). Still, there is limited knowledge on long-term bowel function. This cross-sectional, multicenter study assessed long-term bowel function in a large HD population and examined predictors of poor outcome.METHODS: Patients older than four years or their parents filled out a validated questionnaire on bowel function. Clinical details were recorded retrospectively from medical records.RESULTS: 73/200 (37%) patients reported absolutely no impaired bowel function, meaning no constipation, fecal accidents, stoma, appendicostomy or need for enemas. Seven (4%) had a stoma, and 33 (17%) used antegrade or rectal colonic enemas. Most disarrangements of fecal control and constipation were significantly less common in older age group, but abnormal defecation frequency and social problems remained unchanged. Syndromic patients (n=31) experienced frequent fecal accidents (46%) more often than nonsyndromic (14%, P<0.001). Having a syndrome (adjusted OR 5.6, 95% CI 2.1-15, P=0.001) or a complete transanal ERPT (adjusted OR 2.4, 95% CI 1.1-5.7, P=0.038) was significantly associated with poor outcome defined as having a stoma, an appendicostomy, daily fecal accidents or need of regular rectal wash outs.CONCLUSION: A significant number of HD patients experience bowel problems many years after definite surgery. Fecal control was significantly better in older than younger HD patients, but some continued to have considerable bowel problems also as adults. A total transanal ERPT was associated with poorer outcome. Long-term follow-up of HD patients is warranted. Prognosis Study: Level II.

Impact of spinal cord malformation on bladder function in children with anorectal malformations.
- 2009

In: Journal of pediatric surgery. - : Elsevier BV. - 1531-5037 .- 0022-3468. ; 44:9, s. 1778-85

Journal article (peer-reviewed)abstract
- PURPOSE: Risk factors for the presence of neurogenic bladder dysfunction (NBD) in children born with high anorectal malformations (ARMs), were investigated, to identify the need for urodynamics in these patients. MATERIAL AND METHODS: The study included 37 patients with high ARMs (21 boys and 16 girls). Bladder function was evaluated with urodynamics both before and after anorectoplasty (posterior sagittal anorectoplasty [PSARP]). All patients were investigated with spinal radiograph. Spinal ultrasound was performed in the neonatal period, and magnetic resonance imaging was added in case of abnormal ultrasound or urodynamics and in case of cloacal malformation. RESULTS: In ARM patients with rectourethral and vestibular fistulas and cloacas, NBD was identified in 9 children (25%). The bladder dysfunction was innate in all cases except in one girl with cloaca, indicating that the risk of iatrogenic denervation seems minimal using the PSARP technique. All children with innate NBD had a spinal cord malformation either as spinal cord regression or tethering with or without a lipoma. Concerning vertebral status, almost all children with NBD had partial sacral agenesis. Abnormal perineal appearance was highly correlated to NBD in boys, especially in those with a spinal cord regression malformation. Innate NBD was not found in any child with normal spinal cord. CONCLUSION: From these results, we suggest that spinal ultrasound and perineal inspection are used as screening procedures for NBD in children with ARM. Urodynamic investigation is recommended only when spinal cord anomalies or other signs indicative of NBD are present. In case of spinal cord malformation, repeated urodynamics during follow-up is mandatory because of the risk for developing tethered cord syndrome.

Megarectosigmoid in children with anorectal malformations: Long term outcome after surgical or conservative treatment.
- 2014
-
In: Journal of pediatric surgery. - : Elsevier BV. - 1531-5037 .- 0022-3468. ; 49:4, s. 564-9
-
Journal article (peer-reviewed)abstract
- Megarectosigmoid (MRS) is commonly seen in children with anorectal malformations (ARM) and contributes to the high incidence of constipation. Surgical resection has been advocated by some, whereas others propose intense bowel management as the treatment of choice. The aim of this study was to evaluate outcome of both bowel function and configuration after surgical or conservative treatment of MRS in ARM patients.

Vascular endothelial growth factor and bladder from a different perspective: not only an angiogenic factor.
- 2010

In: Journal of pediatric surgery. - : Elsevier BV. - 1531-5037 .- 0022-3468. ; 45:2, s. 447-52

Research review (peer-reviewed)abstract
- Angiogenesis has a key role for embryonic development and is crucial in several major diseases. Molecular basis of angiogenesis has been widely investigated (J Biochem Mol Biol. 2006;39:469-478, Oncogene. 2000;19:5598-5605). In this review, vascular endothelial growth factor (VEGF) and related receptors and their key roles in embryonic bladder development are discussed. The normal VEGF expression and related angiogenesis pattern of embryonic bladder are highlighted. The VEGF family especially VEGF-A is the major player in angiogenesis as well as many other angiogenic factors and activates 2 tyrosine kinase receptors, VEGFR-1 and VEGFR-2 (J Biochem Mol Biol. 2006;39:469-478). Besides its worthy role in angiogenesis, VEGF-A also seems to participate in normal bladder development (J Urol. 2007;177:1552-1557, Br J Urol Int. 2006;98:217-225). In previous studies, we have shown that exogenous VEGF or hypoxia-induced endogenous upregulation of this protein accelerates the growth of the bladder by detrusor and urothelium hypertrophy and hyperplasia (J Urol. 2007;177:1552-1557, Br J Urol Int. 2006;98:217-225, Dev Biol. 1997;183:139-149, Neurourol Urodyn. 2004;23:342-348). This abrupt role of VEGF on detrusor muscle through a hypoxic pathway may potentially be a part of the solution for many urologic conditions such as remodeling of detrusor muscle in antenatal bladder outlet obstruction.

Controlled long term outcome of pyloromyotomy for pyloric stenosis : No long-term adverse effect
- 2022
-
In: Journal of Pediatric Surgery. - : Elsevier. - 0022-3468 .- 1531-5037. ; 57:11, s. 736-739
-
Journal article (peer-reviewed)abstract
- Purpose: Pyloromyotomy for pyloric stenosis is one of the more common surgical procedures performed on infants. The long-term effects of the procedure are however unclear. The purpose of this study was to study the effects into adult life, compare them with controls and to see if there is a need for structured follow up of patients.Methods: Of the 101 patients operated for pyloric stenosis between 1972 and 1974 at our tertiary referral center 91 could be traced. They were all invited to participate in the study and were sent validated ques-tionnaires (PAGI-SYM, GIQLI) as well as a study-specific questionnaire examining the use of antacid drugs, incidence of gastroscopy and abdominal surgery. Sixty patients responded (66%, mean age 45 years, 46 male) and were included. Thereafter, 600 age and sex-matched controls were sent the same question-naires. 132 responded (22%, 90 male) and were includes as controls.Results: No significant differences could be found in any of the examined parameters when looking at the whole material or the male patients. Female patients had higher PAGI-SYM-scores for post prandial fullness (mean 1.11 vs 0.43, P = 0.035) and heartburn (mean 0.59 vs 0.14, P = 0.043) when compared to controls.Conclusions: The present study shows that most patients operated for pyloric stenosis during infancy experience no negative effects into adulthood. The finding in the female patient group is interesting but is unlikely to have any clinical implications. The results from this study strongly implicate that there is no need for follow up of patients into adulthood.Level of evidence: Level III.

Injectable bulking treatment of persistent fecal incontinence in adult patients after anorectal malformations
- 2020
-
In: Journal of Pediatric Surgery. - : W B SAUNDERS CO-ELSEVIER INC. - 0022-3468 .- 1531-5037. ; 55:3, s. 397-402
-
Journal article (peer-reviewed)abstract
- Background/Purpose: Injectable bulking therapy has emerged as a treatment for fecal incontinence (IT, however there are no studies including adult patients with anorectal malformations (ARM). This study aimed to evaluate non-animal stabilized hyaluronic add with dextranomer (NASHA/Dx) for the treatment of adult ARM patients with persistent FI.Methods: Seven adults with ARM and incontinence to loose stool at least once weekly and without rectal or mucosal prolapse were treated with anal NASHA/Dx injection. They were evaluated preoperatively, at 6 and 18 months with a bowel function questionnaire and a 2-week bowel diary as well as FTQL and SF-36 quality of life questionnaires.Results: Before treatment, the mean number of incontinence episodes over 2 weeks was 20.7 (median 16, range 8-52). At 6 months, the corresponding figures were 53 (median 4, range 0-19, p = 0.018), and at 18 months the figures were 4.3 (median 2, range 1-20,p = 0.018). An improved physical function in SF-36 from 74.3 at baseline to 86.4 at 6 months was noted (p = 0.04). No serious adverse events occurred.Conclusions: NASHA/Dx is a promising treatment option for selected adult patients with persistent Ft after ARM. Longer follow up of larger patient series and studies on patients in adolescence is needed.

Long-term outcome after free autogenous muscle transplantation for anal incontinence in children with anorectal malformations
- 2010
-
In: Journal of Pediatric Surgery. - : Elsevier BV. - 0022-3468 .- 1531-5037. ; 45:10, s. 2036-2040
-
Journal article (peer-reviewed)abstract
- PURPOSE: Patients with high anorectal anomalies are often incontinent after reconstruction, particularly with the older forms of surgical treatment, that is, anorectal pull-through or Stephen's operations. In 1974, a new treatment for anal incontinence in children was introduced at the Akademiska Hospital: free autogenous muscle transplantation (FAMT) to the perirectal area. All the patients receiving FAMT were totally incontinent before the procedure and had no rectal sensitivity. The aim of this study was to evaluate the long-term functional outcome of this procedure. METHODS: Twenty-two patients (17 males) operated on with FAMT below the age of 15 years were identified through records. One of the patients had died, and 2 were not available for follow-up. The remaining 19 were sent a validated bowel function questionnaire, and 15 (78.9%) of 19 patients responded (12 males). These 15 patients were compared with 15 patients with the same sex, age, and a similar malformation from our patient database. RESULTS: At follow-up, after an average of 30 years postoperatively, 2 of 15 patients with FAMT had a stoma compared with 3 of 15 in the control group. The Miller incontinence score had a mean of 6.2 (median, 6; range, 0-15) in the FAMT group and 3.7 (median, 4; range, 0-12) in the control group. All patients in both groups could sense stool, and 11 of 13 patients in the FAMT group could distinguish between feces and flatus. CONCLUSIONS: The patients with FAMT had a slightly inferior anorectal function compared with the controls. Considering they were all totally incontinent before FAMT, we conclude that FAMT has an acceptable effect 30 years postoperatively. Therefore, we find that FAMT could be an alternative for anorectal malformation patients who are totally incontinent.

- Background/purposeKnowledge about the functional outcome in adults with anorectal malformations is essential to organize structured transition to adult care for this patient group. The aim of this study was to investigate the functional outcome and quality of life in adults with anorectal malformations characterized according to the Krickenbeck classification.MethodsOf 256 patients diagnosed with anorectal malformations at our institution in 1961–1993, 203 patients could be traced and were invited to participate in the study. One hundred and thirty-six patients replied (67%) and were compared with one hundred and thirty-six population based sex and age-matched controls. Patients and controls were evaluated with both a validated questionnaire as well as a study-specific questionnaire to assess bowel function. SF-36 was used for quality of life. Outcome in nine incontinence-related parameters, 10 constipation-related, 6 urogenital function-related, and 13 quality of life parameters were assessed in the patients and compared to the outcome of controls as well as to the type of anorectal malformations according to the Krickenbeck classification.ResultsThe ARM-patients had an inferior outcome (P < 0.05) for all incontinence parameters, 8 of 10 parameters for constipation, 2 of 6 for urogenital function and 7 of 13 quality of life parameters. Patients with rectobulbar and vestibular fistulas had the worst statistical outcome but patients with cloaca and rectoprostatic/bladder-neck fistula had worse outcome in absolute numbers. Forty-four patients (32%) reported incontinence of stool at least once a week and 16 (12%) had a permanent colostomy.ConclusionsThe functional outcome and quality of life in adults with anorectal malformations are closely related to the type of malformation. A large proportion of the patients have persistent fecal incontinence, constipation and sexual problems that have a negative influence on their quality of life. Structured multidisciplinary follow-up of adults with anorectal malformations by pediatric and colorectal surgeons, as well as urologists and gynecologists is therefore advocated.

Posterior sagittal anorectoplasty results in better bowel function and quality of life in adulthood than pull-through procedures
- 2015
-
In: Journal of Pediatric Surgery. - : Elsevier BV. - 0022-3468 .- 1531-5037. ; 50:9, s. 1556-1559

Journal article (peer-reviewed)abstract
- Background/purpose: The short-term outcome of posterior sagittal anorectoplasty (PSARP) procedure has been reported to be better than after abdominoperineal or abdominosacroperineal (AP) procedures. This study aimed to investigate the long-term functional outcome and quality of life after PSARP in adulthood and compare with the outcome after AP procedures. Methods: Twenty-four patients operated with PSARP at the Department of Pediatric Surgery, Uppsala, Sweden, from 1984 to 1993 were identified. They were compared with 20 patients that underwent AP pull-through procedures from 1974 to 1983. The patients were sent validated bowel function and quality of life (SF-36) questionnaires. Sixteen PSARP (median age 21, five females) patients and fourteen AP patients (seven abdominosacroperineal and seven abdominoperineal pull-throughs, median age 32, seven females) responded and were included in the study. Results: The median Miller incontinence score was 1 (range 0-13) in the PSARP group and 10 (range 3-16) in the pull-through group (P = 0.0042). The use of underwear protection and oral loperamide was significantly less frequent in the PSARP group (P = 0.0096 and 0.0021 respectively). The SF-36 scores of Vitality, Mental health and Mental Cluster Scale were higher in the PSARP group (P = 0.0291, 0.0500, 0.0421 respectively). Conclusions: PSARP results in superior bowel function and better quality of life in adulthood compared with AP procedures for the repair of anorectal malformations.

Journal article (peer-reviewed)abstract
- The authors describe a 9-year-old boy who had an accident with his bicycle. He presented with hematuria a few weeks later, and cystoscopy results showed a polypod lesion near the veru montanum. The lesion was resected, and histologic examination showed a nephrogenic adenoma (NA), which recurred 6 years later with hematuria. NA is a rare lesion in a child's urethra and can be a source of hematuria.

Prevalence of Mental Health Problems, Associated Factors, and Health-Related Quality of Life in Children with Long-Gap Esophageal Atresia in Sweden
- 2023
-
In: Journal of Pediatric Surgery. - : Elsevier. - 0022-3468 .- 1531-5037. ; 58:9, s. 1646-1655
-
Journal article (peer-reviewed)abstract
- Background: Children with long-gap esophageal atresia (LGEA) face a high risk of digestive and respiratory morbidity, but their mental health outcomes have not been investigated. We aimed to identify the prevalence of mental health problems in children with LGEA, associated factors and health-related quality of life (HRQOL).Methods: Twenty-six children with LGEA aged 3-17 were recruited nationwide in Sweden. One of their parents and adolescents aged 11-17 completed information on the child's mental health (Strength and Difficulties Questionnaire), generic (PedsQL 4.0) and condition-specific HRQOL (EA-QOL). Parents gave information on current child symptomatology. Mental health level was determined using validated norms; abnormal >= 90 percentile/borderline >= 80 percentile/normal. Elevated levels were considered borderline/abnormal. Data were analyzed using descriptives, correlation and Mann-Whitney-U test. Significance level was p < 0.05.Results: Twelve children with LGEA aged 3-17 (46%) had elevated scores of >= 1 mental health domain in parent-reports, whereas 2 adolescents (15%) in self-reports. In parent-reports, 31% of the children had elevated levels of peer relationship problems, with associated factors being child sex male (p = 0.037), airway infections (p = 0.002) and disturbed night sleep (p = 0.025). Similarly, 31% showed elevated levels of hyperactivity/inattention, and associated factors were male sex (p = 0.005), asthma (p = 0.028) and disturbed night sleep (p = 0.036). Elevated levels of emotional symptoms, seen in 20%, were related to swallowing difficulties (p = 0.038) and vomiting problems (p = 0.045). Mental health problems correlated negatively with many HRQOL domains (p < 0.05).Conclusions: Children with LGEA risk mental health difficulties according to parent-reports, especially peer relationship problems and hyperactivity/inattention, with main risk factors being male sex, airway problems and sleep disturbances. This should be considered in follow-up care and research, particularly since their mental health problems may impair HRQOL.

Journal article (peer-reviewed)abstract
- Background/Purpose: A successful outcome in the repair of esophageal atresia (EA) is associated with a high quality pediatric surgical centre, however there are several controversies regarding the optimal management. The aim of this study was to investigate the outcome and management EA in a single pediatric surgical centre.Methods: Medical records of infants with repaired EA from 1994 to 2013 were reviewed.Results: 129 infants were included. Median follow-up was 5.3 (range 0.1-21) years. Overall survival was 94.6%, incidences of anastomotic leakage 7.0%, recurrent fistula 4.6% and anastomotic stricture 53.5% (36.2% within first year). In long gap EA (n = 13), delayed primary anastomosis was performed in 9 (69.2%), gastric tube in 3 (23.1%) and gastric transposition in one (7.7%) infants. The incidences of anastomotic leakage and stricture in long gap EA were, 23.1% and 69.2%, respectively. Peroperative tracheobronchoscopy and postoperative esophagography were implemented as a routine during the study-period, but chest drains were routinely abandoned.Conclusion: The outcome in this study is fully comparable with recent international reports showing a low mortality but a significant morbidity, especially considering anastomotic strictures and LGEA. Multicenter EA registry with long-term follow up may help to establish best management of EA.

Journal article (peer-reviewed)abstract
- The aim was to investigate whether young children with drug-refractory nausea and vomiting can be treated with gastric electrical stimulation (GES) in a similar way as adults and to evaluate whether temporary percutaneous gastric electrical stimulation (TPGES) can be used in the pediatric population to select the patients who are responders to GES treatment. We report the clinical results in 3 children between 2 and 3 years of age. To the best of our knowledge, these are the youngest patients treated with GES.

- Background: Peritoneal adhesions may cause bowel obstruction, infertility, and pain. This study investigated cytokines, proteins and growth factors thought to promote formation of adhesions in an experimental intraabdominal adhesion model. Methods: Male Sprague-Dawley rats were subjected to laparotomy, cecal abrasion, and construction of a small bowel anastomosis and examined at various time points after surgery. Concentrations of cytokines and growth factors in plasma and peritoneal fluid were analyzed using electrochemoluminescence and quantitative sandwich enzyme immunoassay technique. Results: Concentrations of interleukin-6 (IL-6), interleukin-1beta (IL-1 beta), and tumor necrosis factor alpha (TNF-alpha) increased in peritoneal fluid from 6 h after incision. Plasma concentrations of IL-6 increased at 6 h, but plasma concentrations of IL-1 beta and TNF-alpha remained low. Peritoneal fluid concentrations of platelet-derived growth factor-BB (PDGF- BB), transforming growth factor beta1 (TGF-beta 1), vascular endothelial growth factor (VEGF), tissue-type plasminogen activator (tPA) and plasminogen activator inhibitor-1 (PAI-1) were below detection levels at all time points. Conclusion: Early elevations of IL-6, IL-1 beta, and TNF-alpha concentrations in peritoneal fluid correlated to adhesion formation in this rodent model. Our model is relevant and reproducible, suitable for intervention, and indicates that antiadhesion strategies should be early, local and not systemic.

- Background: Intraperitoneal adhesions cause significant morbidity. They occur after peritoneal trauma, which induces oxidative stress with production of inflammatory cytokines, peroxidized proteins (carbonyls) and lipids (aldehydes). This study aimed to investigate if carbazate-activated polyvinyl alcohol (PVAC), an aldehyde-carbonyl inhibitor, can reduce intraperitoneal adhesions in an experimental model.Material and methods: Male Sprague-Dawley rats (n = 110) underwent laparotomy, cecal abrasion and construction of a small bowel anastomosis. They either were treated with intraperitoneal instillation of PVAC or were sutured with PVAC-impregnated sutures. Thromboelastography analysis was performed using human blood and PVAC. The lipid peroxidation product malondialdehyde (MDA) and inflammatory cytokines IL-1 beta and IL-6 were quantified in peritoneal fluid. At day 7, bursting pressure of the anastomosis was measured and adhesions were blindly scored.Results: PVAC in human blood decreased the production of the fibrin-thrombocyte mesh without affecting the coagulation cascade. MDA, IL-1 beta and IL-6 were increased after 6 h without significant difference between the groups. PVAC-impregnated sutures reduced intraperitoneal adhesions compared to controls (p = 0.0406) while intraperitoneal instillation of PVAC had no effect. Anastomotic bursting pressure was unchanged.Conclusions: Intervention with an aldehyde-carbonyl inhibitor locally in the wound by PVAC-impregnated sutures might be a new strategy to reduce intraperitoneal adhesions.

- Increased pulmonary vascular resistance causing pulmonary artery hypertension is a major problem in the treatment of congenital diaphragmatic hernia with a strong association to mortality. We here report a patient with intractable pulmonary hypertension at 4 weeks of age unresponsive to conventional treatment. After administration of the platelet-derived growth factor (PDGF) receptor antagonist imatinib, pulmonary artery pressure gradually decreased to acceptable levels and the patient's clinical condition gradually improved.
