Femoral-tibial bypass for calcific arterial disease.
Overt calcification of the recipient artery and outflow bed has been regarded as a poor prognostic factor for femoral-distal arterial bypass patency and subsequent wound healing. In order to determine the short- and long-term limb salvage and graft patency rates achieved in these patients, the records of 35 patients undergoing 38 attempted femoral-tibial bypasses to a calcified recipient artery were reviewed. Two patients were unreconstructable at the time of surgery. Thirty-one of the 36 operations (86 percent) were performed using in situ saphenous vein bypass techniques, 3 were performed with polytetrafluoroethylene (PTFE), 1 with a composite sequential, and 1 with a composite vein graft. Immediate limb salvage was achieved in 31 of 36 limbs (86 percent). Five early below-knee amputations (14 percent) were required, two due to graft thromboses and three due to progressive foot necrosis despite patent grafts. One patient (3 percent) died secondary to sepsis. Three-year primary graft patency and limb salvage rates did not differ significantly from bypasses to noncalcified vessels. Femoral-distal bypass in the presence of overt calcific arterial disease may be successfully accomplished and offers an excellent prognosis for long-term graft patency and limb salvage.
