title: Surgical management of popliteal aneurysms. Trends in presentation, treatment, and results from 1952 to 1984.
abstract: Graft replacement was performed for 123 (77%) of 160 popliteal aneurysms evaluated at The Cleveland Clinic from 1952 to 1984, employing autogenous saphenous vein in 58 (36%), polytetrafluoroethylene in 19 (12%), and of historic interest, Dacron (12%) or arterial homograft (16%) in 46. The 10-year cumulative patency (CP) rate was 56% and the limb salvage (LS) rate was 83% following graft replacement, but late results were superior in patients who received vein bypass (CP, 94%; LS, 98%), in those who underwent revascularization before ischemic complications had occurred (CP, 92%; LS, 96%), and in those who recovered both pedal pulses (CP, 64%; LS, 96%). Long-term asymptomatic limbs were restored in 96%, 92%, and 89% of these subsets, respectively, compared with 65% of those receiving other graft materials (p = 0.00003), 59% of those with preoperative ischemic symptoms (p = 0.00001) and 68% of those regaining only an isolated popliteal pulse (p = 0.0326). These data indicate that popliteal aneurysms should be corrected by vein bypass to a patent tibioperoneal segment before spontaneous thrombosis or embolization eliminates the critical outflow bed.
