Although minor amputations can lead to limb preservation in most patients, the performance of a revascularization subsequent to amputation, transmetatarsal as the initial amputation, and end-stage renal disease are poor prognostic indicators. Inferior long-term patient survival is most closely associated with renal insufficiency and conversion to major amputation early after the initial procedure.

Preoperative mucosal tattooing with india ink is recommended as a safe and necessary procedure.

Endovascular repair of aortic and iliac artery PAAs is technically feasible and provides a high rate of lesion exclusion. Morbidity and mortality rates appear lower than those reported for open surgical repair. These patients can typically be discharged by the second postoperative day. Endovascular therapy for stable ruptured PAAs can be successfully performed and should be considered as an option only when appropriate devices and expertise are available. For uncomplicated PAAs of the aorta and iliac arteries, endovascular therapy may be more favorable than surgical repair.

Despite suggestive experimental data regarding endograft healing in animals, minimal graft incorporation was apparent in the stent grafts recovered in this study. A greater emphasis on the construction and mechanism of fixation of endograft attachment systems will be important for long-term device function.

Lower extremity bypass can be performed safely and effectively in patients who have undergone renal transplantation. However, the importance of a well-functioning renal allograft at surgery is demonstrated by marked improvement in patient survival.
