Successful long-term limb salvage using cephalic vein bypass grafts.

Successful long-term limb salvage using cephalic vein bypass grafts was attained in 70 limbs of 67 patients over the past 11 years. The saphenous vein was absent in 76% and inadequate in 24% of the cases. Revascularization for limb salvage was carried out in 83%. Ninety per cent of the grafts were extended to the infrageniculate level while 56% were to a tibial vessel. Patency rates at 1, 3, and 5 years were 85%, 72%, and 68%, respectively. Limb salvage rate was 85% at 5 years and thereafter. There were no operative deaths or upper extremity morbidity. The 5-year survival rate was 50%. The results obtained with cephalic vein were comparable to those reported using saphenous vein but superior to those reported for nonautogenous bypass grafts.

Patency of femoropopliteal and femorotibial grafts after outflow revascularization (jump grafts) to bypass distal disease.

Repair of failing femorodistal bypass grafts with secondary distal "jump" grafts was performed 34 times in 33 patients. Indication for operation was limb salvage for all distal jump grafts and for 85% of the initial femorodistal bypass grafts. Autogenous vein bypass grafts were used in 28 of 33 initial femorodistal grafts (85%) and in 29 of 34 secondary jump grafts (85%). Sixteen of the 33 initial grafts in jeopardy extended to the infrapopliteal level (48%) and 19 of the jump grafts terminated in foot or ankle arteries (56%). The 12 jump grafts performed in the first 2 months of the initial graft were associated with high rates (9%) of graft thrombosis and amputation. Early loss of viability of initial grafts probably resulted from technical and judgment errors or underestimation of distal disease. Progression of distal disease produced late failure after 1 year of implantation of the initial grafts. The 1-year patency rate of the initial femorodistal grafts was 63% but only 32% of these grafted limbs were viable and were not at risk of amputation. Distal jump grafts produced a 49% improvement in limb viability (to an 81% limb salvage rate) and an 11% increase in the initial graft patency rate (to 74%) at 1 year.
