Most patients who undergo infrainguinal bypass surgery for limb salvage require ongoing treatment and have persistent or recurrent symptoms until their death. A significant minority have major tissue loss despite successful initial surgery. Clinically important palliation is frequently achieved by bypass surgery, but ideal results are distinctly infrequent.

These results show an improvement with the conventional management of IRAI equal or superior to those results reported with alternative methods, including femoral vein grafts or aortic allografts. These results should be regarded as the modern standard with which alternative therapies can be compared.

Patients undergoing open AAA repair generally experienced significant freedom from surgical complications. However, substantial functional impairment was present. It is unclear whether the functional disability resulted from the AAA surgery or from aging and comorbidities unrelated to surgery.

Patients with symptomatic PAD experience symptoms of ongoing LED, CVD, and CHD with a frequency that is not influenced by the site(s) of their original symptoms. The hypothesis that lesions and resulting symptoms of systemic atherosclerosis occur at various anatomic sites as a matter of random chance should be tested with other studies.
