Results obtained with femorotibial bypass performed for claudication were superior to those obtained for limb salvage and were equivalent to those obtained with femoropopliteal bypass for claudication. The results obtained in this highly selected cohort suggest that patients at low risk with significant functional impairment from claudication, available autogenous vein, and suitable tibial outflow to the ischemic muscular bed can be offered revascularization with the expectation of durable long-term results.
Lower extremity atherosclerosis results in significant morbidity in women, particularly in women following the menopause. Up to 25% of women aged 55 to 74 years are affected by this disease. When noninvasive testing is used to determine the prevalence of lower extremity atherosclerosis, and men in this age group are equally represented. Cigarette smoking, diabetes mellitus, and menopause are risk factors for atherosclerosis of particular interest in women. The prevalence of cigarette smoking is rising rapidly among women, and diabetes appears to be a greater risk factor for atherosclerosis in women than in men. Risk factor reduction, in addition to an exercise program, are important parts of the treatment program for stable claudication. In both men and women with more severe symptoms, an ankle/brachial index (ABI) of less than 0.3 is associated with a poor prognosis. Men and women fare equally well following revascularization for severe peripheral atherosclerosis. However, there are some data to suggest that women may be offered peripheral revascularization at a lower rate.
Fifty-four patients underwent 56 profundaplasties for limb salvage. All had stenosis greater than 50% in diameter of the deep femoral artery and associated superficial femoral artery occlusive disease. After profundaplasty, ischemic ulcers healed in 9 of 17 (53%) patients. Rest pain was relieved in 6 of 19 (32%) and areas of ischemic necrosis healed in 7 of 20 (35%). Cumulative patency of the deep femoral artery was 49% at 3 years but fell to 21% at 5 years, whereas cumulative limb salvage was 49% and 36%, respectively. Eleven of the required 28 amputations were performed in the immediate postoperative period. Profundaplasty was used to lower the amputation level and preserve the knee joint in six patients. The other five early amputations occurred in severely ischemic limbs without distal vessels suitable for bypass. The profundaplasty remained patent in all 19 patients who underwent below-knee amputation and 16 (84%) became ambulatory with a prosthesis. Hemodynamic data provided by determination of the profundapopliteal collateral index predicted limb salvage in 10 of 11 (91%) of limbs when the index value was less than or equal to 0.19. Other clinical criteria, such as preoperative ankle-brachial index and the presence of diabetes mellitus, had no predictive value. Isolated profundaplasty for limb salvage is an effective first procedure for selected patients and provides a reasonable alternative to primary amputation or high-risk distal bypass. When amputation is inevitable, effective perfusion of the profunda femoris artery is essential for preservation of the knee joint and results in a high degree of functional rehabilitation.

Hemodynamic data provided by determination of the profimdapopliteal collateral index predicted limb salvage in 10 of 11 (91%) of limbs when the index value was ~<0.19. Other clinical criteria, such as preoperative ankle-brachial index and the presence of diabetes mellitus, had no predictive value.

When amputation is inevitable, effective perfusion of the proftmda femoris artery is essential for preservation of the knee joint and results in a high degree of functional rehabilitation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
