- 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.

- OBJECTIVES: to assess the quality of life after successful intervention among patients with varying degrees of lower-limb ischaemia in comparison with healthy controls and the respondents>> degree of sense of coherence. MATERIALS AND METHODS: one hundred and twelve patients and 102 healthy controls were assessed for quality of life (Nottingham Health Profile) and sense of coherence. MAIN RESULTS: successful angioplasty or surgical intervention led to an improved quality of life at 6 months, in particular with regard to pain, sleep, physical mobility, hobbies and holiday and to a level similar to healthy controls in sleep, social isolation, paid employment and family relationships. It remained at a significantly lower level than that of healthy controls with regard to pain, emotional reactions, physical mobility, energy, housework, hobbies, holidays, sex and social life. Critical ischaemia patients did not reach the same level of quality of life as the claudicants or the healthy controls. CONCLUSION: successful treatment for chronic limb ischaemia improved the quality of life significantly, more so in claudicants than in patients with critical ischaemia. The degree to which the quality of life improved was associated with the patients>> sense of coherence and their ankle pressure.

- 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.

- 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.
