Lack of diameter effect on short-term patency of size-matched Dacron aortobifemoral grafts

摘要: Abstract This study examined the relationship between graft diameter and subsequent patency in 79 patients who received Dacron aortobifemoral bypass grafts for aortoiliac occlusive disease 1985 1989. Sixty-five percent of these were men, 25% diabetic, 94% smokers, with an average age 62 years. Patients followed a mean interval 24 months. Life-table survival was 92% at 3 All surviving showed "significant" postoperative improvement by use Society Vascular Surgery/International Cardiovascular Surgery combined clinical vascular laboratory criteria. There three early five late thromboses. Primary secondary life-table patencies 85% 92%, respectively, bifurcation selected to match size native arteries. receiving small grafts, defined as 12 mm ( n = 9) 14 39), compared large 16 26) 18 5). Small more likely be used women p 0.74). Furthermore, none other variables listed above influenced patency. We conclude that is not affected when appropriately matched vessel size.
