Abstract
Progression of peripheral vascular disease may lead to major amputations. We sought to understand whether more frequent endovascular angioplasty and stenting in patients with limb-threatening ischemia would affect the number of major amputations. We retrospectively reviewed the effects of implementing more frequent endovascular intervention for the 4 years 2003-2006 at the Veterans Affairs Medical Center in Long Beach, California. During this interval angioplasty became the preferred method for the treatment of infrainguinal vascular disease. Open bypass procedures were performed for patients with limb-threatening ischemia and extensive lesions that could not be treated by angioplasty. Patients were on average 68 ± 1 years, and 96% were male. The patients were 45% active smokers, with 43% diabetics. There was 0% 30-day mortality for both groups over the 4 years. the number of below-the-knee, above-the-knee, and transmetatarsal amputations for fiscal years 2003, 2004, 2005, and 2006 were, 42, 50, 62, and 41, respectively. Concurrently, there has been a reduction in open femoral to popliteal or trifurcation vessel bypasses with 37, 43, 28, and 14 procedures for 2003, 2004, 2005, and 2006. Angioplasty and stenting increased from 12, 12, 24, to 59 over the same period. Patients who had a femoral to distal bypass were more likely to have an amputation than those undergoing angioplasty (odds ratio = 4.2, 95% confidence interval 1.6-11.5) for those with at least 1 year of follow-up, likely due to these patients having more severe disease. Increasing the frequency of angioplasty for infrainguinal vascular lesions did not increase the number of major lower extremity amputations in our stable patient population.
