Abstract

Chronic obstructive lesions of the subclavian artery (SCA) often result in subclavian steal syndrome, which leads to arm claudication, transient cerebral ischemia, and other serious complications. The lesions are classified as stenosis and occlusion, according to the degree of obstruction. Unlike totally occlusive lesions, including ostial occlusions, stenotic lesions have an excellent technical success rate. In the present study, ostial occlusions were classified into 4 types according to their angiographic appearance. A total of 8 patients (6 male, 2 female) with SCA occlusions were treated with percutaneous transluminal angioplasty and stenting over a 4‑year period. Mean patient age was 65.6 years (range, 60‑72 years). In total, 9 self‑expanding and 1 balloon‑expandable stent were implanted at the ostia of the SCA in 7 of the patients. One female patient did not undergo stenting. Bleeding at the access site was noted in 2 patients and was controlled by gauze pressure. The patient that did not undergo stenting was lost to follow‑up with symptoms of a transient ischemic attack at 3 months. The mean follow‑up time for the remaining 7 patients was 15.7 months (range, 1‑36 months). No ischemic symptoms, neointimal hyperplasia, or restenosis was observed in these patients. The transfemoral artery operation approach is preferred for rat‑tail and peak type occlusions, whereas the dual approach involving both femoral and radial arteries is preferred for hilly and plain type occlusions. The angiographic morphology typing used in the present study may serve as a reference to decide upon the interventional operation strategy to be used for improving the technical success rate.
