The purpose of this study was to review our results with axillofemoral by-passes performed for aorto-iliac occlusive disease. Fifty patients receiving 51 axillofemoral by-passes from January 1989 to December 1994 were retrospectively reviewed. The 30-day post-operative mortality was 4%. Seven patients (14%) presented graft-related local complications and all but one required reoperation. Five patients were lost to follow-up, the mean length of which was 36 months (16-74 months). Forty-nine per cent of the patients died during the follow-up period. At 36 months, the primary patency rate was 51%, the secondary patency rate was 69%, and limb valvage rate was 87%. A statistical difference was seen in the secondary patency rate between axillobifemoral by-pass (87%) and axillo-unifemoral by-pass (56%) at 36 months (P < 0.01), but no difference was seen in the limb salvage rate at 36 months between the two configurations of the by-pass (94% vs 81%) (P = NS). Twenty patients (40%) operated upon for acute ischemia had a significantly higher post-operative mortality rate (10% vs 0), a significantly higher amputation rate (20% vs 6.6%) and a significantly lower patency rate of by-pass (26% vs 63%) (P < 0.01), than the 30 patients (60%) operated on for claudication, rest pain or trophic ulcers. Our findings indicate that the results of axillofemoral by-pass are significantly influenced by the selection of patients for operation, namely the clinical status of ischaemic symptoms, and that since the overall results of axillofemoral by-pass are inferior to those of aortofemoral by-pass, this treatment should be restricted to patients at high risk of aortic clamping.
The purpose of the present study was to retrospectively evaluate the results of anatomically tunneled grafts to the anterior tibial artery for distal revascularization in terms of patency and limb salvage rates as well as local morbidity, which can lengthen the postoperative hospital stay. Twenty-three patients received 24 bypasses to the anterior tibial artery, with grafts tunneled through the interosseous membrane. The mean age was 67 years; 10 patients were diabetic, 12 were smokers, 9 presented with significant coronary artery disease, and 2 with chronic renal insufficiency. The donor vessel was the common femoral artery in 17 cases, the superficial femoral artery in 4, and the infra-articular popliteal artery in 3. The graft material consisted in the reversed saphenous vein in 4 cases, the non-reversed devalvulated ex situ saphenous vein in 11, composite polytetrafluoroethylene (PTFE) + inversed saphenous vein in 6, and PTFE alone in 3 cases. No postoperative mortality was observed, nor was there postoperative graft occlusion or need for major amputation. The average postoperative length of stay in the hospital was 9.7 days. Two local surgical wound complications were observed, which did not necessitate a postoperative hospital stay exceeding 15 days. Cumulative primary patency and limb salvage rates at 3 years were 50% and 70%, respectively. Anatomic tunneling of grafts to the anterior tibial artery yields patency and limb salvage rates comparable to those reported in the literature for distal bypasses and, considered overall, an acceptably low local morbidity and short hospital stay. Definitive superiority over externally tunneled grafts, however, is not definitely demonstrated by this study and should be prospectively tested.
Five seat-belt-related injuries occurring in four adults are reported. One injury involved the common carotid artery, two the internal carotid and two the subclavian arteries. Three of the four injured persons were asymptomatic and one had delayed-onset symptoms; none suffered stroke. There was no operative mortality or morbidity. Overall, the functional results of arterial reconstruction were good, with satisfactory patency at follow-up averaging 15 months.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
