- Persistent aneurysm perfusion represents failure of endovascular repair. The leak may occur around either end of the prosthesis or through a collateral route. Most cases can be treated by endovascular means. Stents can be rotated, the prosthesis can be lengthened at either end, and collateral pathways can be occluded, all without recourse to open repair. This report describes the management of persistent aneurysm perfusion in five patients from a total experience of 32 cases of endovascular aneurysm repair.

- OBJECTIVES: To assess quality of life in patients with varying degrees of ischaemia in comparison with controls, and to determine whether the degree of lower limb ischaemia and sense of coherence were associated with quality of life. MATERIALS AND METHODS: 168 patients, including 93 claudicants and 75 patients with critical ischaemia and 102 controls were studied. Quality of life was assessed using the Nottingham Health Profile in addition to the Sense of Coherence scale. MAIN RESULTS: Patients with lower limb ischaemia scored significantly reduced quality of life in all aspects compared to controls. Pain, physical mobility and emotional reactions were the significant independent factors when using logistic regression analysis. The grade of disease and low sense of coherence were significantly associated with low quality of life. Increasing lower limb ischaemia significantly conferred worse pain, sleeping disturbances and immobility. CONCLUSION: This study showed that the quality of life was impaired among patients with lower limb ischaemia, in all investigated respects. The degree to which quality of life was affected seems to represent an interplay between the grade of ischaemia and the patient's sense of coherence. This suggests the need for a multidimensional assessment prior to intervention.

- The effects of fat content and thickeners, propylene glycol alginate (PGA; 1.40%) and guar gum (1.55%), on sensory and instrumental quality descriptors on reduced fat mayonnaises (15 and 30% fat) with and without added aroma compounds, citral (semi-polar) and pyroligneous acid (polar), were investigated. One mayonnaise, 82% fat, without added thickener or aroma compounds was used as reference. Sensory evaluation (quantitative descriptive analysis; QDA), rheological analysis (yield stress, maximum viscosity, G' and G''), measurements of particle size and headspace CC-MS analyses were carried out. Correlations between the results were developed Perceived and instrumental texture, and perceived smell and flavour, changed differently in magnitude and direction due to fat content and type of thickener.

- The association between known prognostic variables and altered immunostaining for the nuclear proteins retinoblastoma (Rb) and p53 was studied in a homogeneous series of locally advanced bladder cancer. The predictive value of this immunostaining for the local response to intended radical radiotherapy was investigated. Among 262 patients treated with intended radical radiotherapy between 1967 and 1986, a total of 154 patients were evaluable with respect to local response to treatment. The paraffin-embedded specimen from the tumour prior to irradiation was immunostained with the monoclonal antibodies PMG3-245 for Rb and 1801 for p53 nuclear proteins after heating in a microwave oven for 40 min at 650 W. An altered expression of Rb and p53 was observed in 18 and 42% of the tumours, respectively. p53 overexpression was associated with higher tumour grade. However, the results of the p53 and Rb immunostaining procedures had no predictive value for tumor response to radiation treatment, local control or cancer-specific mortality.

Renal arteries covered by aortic stents: clinical experience from endovascular grafting of aortic aneurysms

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: During the endovascular repair of abdominal aortic aneurysms (AAAs), effective anchoring of the stent-graft is difficult in the presence of a short infrarenal aneurysm neck. The aim of this study was to investigate renal artery patency and renal function after deployment of graft anchoring stents across the renal arteries. DESIGN: Retrospective open study. PATIENTS: Twenty-five renal arteries, in 18 patients treated by endovascular exclusion of an AAA, were intentionally covered with the Gianturco Z-stent to ensure stent graft attachment. METHODS: Renal artery patency was assessed by repeated spiral computed tomography (CT) scans and angiography. Creatinine levels, blood pressure and antihypertensive medication were recorded. Follow-up was a median 6 months (2-9). RESULTS: All 25 stent-covered renal arteries remained patent. CT showed a small infarct in one kidney. Creatinine was 108 mumol/l (89-133) before intervention and 98 mumol/l (87-127) at follow-up. Blood pressure was 150/80 mmHg on both occasions. Antihypertensive therapy was intensified in one patient whose creatinine level remained stable and whose separate renin sampling was normal. CONCLUSIONS: Covering the renal arteries with the Gianturco Z-stent does not seem to affect renal function within 6 months. Further follow-up is needed before suprarenal stent deployment can be advocated.

Are self-expanding stents superior to balloon-expanded in dilating aortas? An experimental study in pigs

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To study the stent/vessel interaction and distensibility following the natural increase in vascular diameter using self-expanding and balloon-expanded stents. DESIGN: Open experimental study. SETTING: Animal laboratory, university hospital. MATERIALS AND METHODS: Eight Palmaz (P) and eight Gianturco (G) stents were transluminally placed in the infrarenal aortas of 16 pigs. Pulsatile diameter changes above, at and below the stents were non-invasively monitored with an ultrasound phase-locked echo-tracking system before and immediately after stenting and at 4 and 18 weeks. Blood pressure was registered intra-arterially and stiffness (beta) was calculated. Intravascular ultrasound (IVUS) was performed at 18 weeks. RESULTS: Median weight increased from 20 kg (19-26) to 93 kg (62-130). Diameter of the aorta increased 60%. In group P no pulsatile diameter change could be measured at the stent (beta = infinity). In group G stenting increased stiffness from beta 20.7 (9.2) to 43.2 (8.0) (p < 0.05). After 18 weeks stiffness returned to beta 20.1 (12.4). Expanded, median diameter of the P stents was 7.4 (0.8) mm, not increasing after 18 weeks. Initial diameter of the G stents was 7.8 (1.0) mm, increasing 56% to 12.2 (2.3) mm (p < 0.05). IVUS revealed the G stents to be well attached to the vascular wall, but five P stents were detached within half of the circumference. CONCLUSION: Self-expanding stents follow the pulsatile diameter change of the vessel wall, not adversely affecting distensibility after 18 weeks. They show good attachment despite 56% dilation. In contrast, the balloon-expanded stents do not show pulsatile movement and may detach during vessel diameter increase. This may be of importance when choosing stents for endovascular treatment of abdominal aortic aneurysms.

- OBJECTIVES: To study bowel ischaemia in transfemorally placed endoluminal grafting (TPEG) for abdominal aortic aneurysms, and any relation to cytokine response or postoperative fever. DESIGN: Prospective not randomised. University hospital setting. MATERIAL: Fourteen cases of conventional surgery and 23 cases of endovascular technique for infrarenal abdominal aortic aneurysm repair. METHODS: Tonometry was used for sigmoid colon pH, and ELISAs for serum IL-6. RESULTS: Mucosal pH in the sigmoid colon fell significantly during clamping and reperfusion in both groups. Lowest measured sigmoid colon pH was 7.10 in the open group, compared to 7.22 in the TPEG group (p < 0.05). The IL-6 levels in serum peaked after 4 h of reperfusion; 249 pg/ml in the open group, compared to 89 pg/ml in the TPEG group (p < 0.05). High levels of IL-6 in the postoperative period and persisting low sigmoidal pH were associated with serious complications. Postoperative temperature did not differ significantly between the groups, and no significant correlation could be found with sigmoid colon pH or IL-6 levels. CONCLUSIONS: The less pronounced perioperative bowel ischaemia in TPEG patients indicates an advantage of the TPEG technique. Splanchnic ischaemia was not related to postoperative fever, nor the IL-6 or TNF response.
