Value of Cutting Balloon Angioplasty for Limb Salvage in Patients with Obstruction of Popliteal and Distal Arteries

Abstract

Popliteal-to-distal bypass is still the gold standard for limb salvage. However, some patients, especially elderly or diabetic patients, are not eligible for such treatment; and problems may arise, including poor healing of distal surgical wounds, delayed resumption of ambulation, and prolonged hospitalization. This prospective multicenter study carried out on an intent-to-treat basis includes 53 extremities in 48 patients presenting critical ischemia due to infrageniculate arterial lesions with no proximal lesions. Two populations were isolated: diabetic patients (56.6%) and elderly patients over 80 years (45%). In 82% of cases the arterial lesions were long, i.e., more than 1 cm. The limb salvage rate at 1 year was 81%. Postoperative mortality was 9%, and mortality at 1 year was 22.6%. These results show that cutting balloon angioplasty can be proposed as primary treatment in patients with critical ischemia due to popliteal and distal artery lesions.
