[Isolated proximal revascularization for double aorto-iliac and femoral lesions].

From 1980 to 1990, 101 limbs were revascularized at the upper level only in 67 patients, while they presented with associated aortoiliac and femoral obstructive lesions. The symptoms disappeared after aortofemoral revascularization in 94% of the limbs operated on for claudication and 80% of those operated on for critic ischemia. Surgery of the deep femoral artery was associated in 51% of all cases. The average time lapse is 58 months. No complementary revascularization was needed in the cases of claudication. Out of the patients operated on for critic ischemia, upper revascularization was insufficient in 8 cases. Two of the operated patients were cured after secondary downstream revascularization (4%). Three operated patients still presented with intermittent claudication (6%), and 3 were amputed due to acute iliac obstruction seen at an advanced stage. As no reliable predictive test is available, we find it justified to carry out only upper revascularisation in most cases and to decide on the need for secondary downstream extension according to the clinical outcome. However, simultaneous revascularization at both levels is required in case of extensive involvement of the deep femoral artery, such as observed in only 5 of the patients operated during the same period.
