Femorofemoral grafts for lower limb ischemia caused by intra-aortic balloon pump.

From January 1975 to December 1985, 1454 patients had an intra-aortic balloon inserted for cardiac assistance. Eighty balloon-dependent patients had severe limb ischemia and required a femorofemoral graft (FFG) (5% of the total group of patients). Twenty-nine of the 80 patients with grafts (or 36%) left the hospital and 28 were followed up for an average of 40 months to determine late complications associated with the crossover grafts. All grafts remained patent. The 28 patients were classified into five groups according to the degree and type of lower limb ischemia. Group I consisted of 13 asymptomatic patients (46%); group II had four (14%) patients with mild claudication caused by preexisting peripheral arteriosclerosis; group III comprised four patients (14%) without preexisting disease but claudication subsequent to the FFG; group IV had five patients with irreversible ischemic sequelae before grafting ending in amputation, foot drop, or persistent paresthesia; and group V consisted of two patients with graft infection (7%). The perioperative mortality rate of the balloon-dependent patients with an FFG (64%) reflects the gravity of the cardiac condition. Placement of an FFG to relieve limb ischemia in these patients is followed by few immediate or late complications in the survivors and any persistent limb changes were related to the prolonged ischemia present before revascularization. Our data suggest that in balloon-dependent patients with limb-threatening ischemia, aggressive use of the FFG is limb-saving, durable, and allows continuation of balloon support.
