Screened individuals' preferences in the delivery of abdominal aortic aneurysm repair.

BACKGROUND: This study aimed to determine preferences for service attributes in a population screened for abdominal aortic aneurysm. METHODS: A questionnaire was designed to encompass various aspects of service provision. Questions were calibrated against the time an individual was willing to travel to access specific attributes. Subjects attending an aneurysm screening programme were asked to complete a questionnaire before their screening ultrasound scan. Statistical analysis was through pairwise analysis of the median travel times with the signed rank test. The Wilcoxon rank sum, analysed by the Kruskal-Wallis test, was used to compare preference ratings. RESULTS: A total of 262 individuals were asked to complete the questionnaire; the response rate was 98.5 per cent. Approximately 92 per cent of individuals stated a willingness to travel for at least 1 h beyond their nearest hospital in order to access services with a 5 per cent lower perioperative mortality rate, a 2 per cent lower amputation or stroke rate, a high annual caseload of aneurysm repairs, and routine availability of endovascular repair. CONCLUSION: Patients attending aneurysm screening were willing to travel beyond their nearest hospital to access a service with better outcomes, higher surgical volumes and endovascular surgery.

Indications for thrombolysis in deep venous thrombosis.

OBJECTIVES: Deep venous thromboses (DVTs) are a significant cause of morbidity and mortality in the general and inpatient population. Current anticoagulation therapy is efficient in reducing thrombus propagation but does not contribute to clot lysis or prevention of post-thrombotic limb syndrome. Catheter directed thrombolysis (CDT) is an alternative method for treating DVTs but there is no consensus regarding indications for its use. DATA SOURCES: PubMed and Cochrane library were searched for all articles on deep vein thrombosis and thrombolysis. REVIEW METHOD: Articles presenting data on DVT thrombolysis, DVT anticoagulation, mechanical thrombectomy, venous stenting and May-Thurner's syndrome were considered for inclusion in the review. RESULTS: CDT reduced clot burden, DVT recurrence and may prevent the formation of post-thrombotic syndrome. Indications for its use include younger individuals with a long life expectancy and few co-morbidities, limb-threatening thromboses and proximal ilio-femoral DVTs. There is a marked lack of randomised controlled trials comparing CDT-related mortality and long term outcomes compared to anticoagulation alone. The effectiveness of combined pharmaco-mechanic thrombectomy, although promising, need to be further investigated, as is the role of caval filters in preventing DVT-associated pulmonary emboli. CONCLUSIONS: These results suggest that the outcome of CDT in DVT management are encouraging in selected patient cohorts, but further evidence is required to establish longer term benefits and cost-effectiveness.
