Intraluminal Treatment for Persistent Sciatic Artery Aneurysm with VIABAHN

Abstract

A 67-year-old woman was referred to the department of orthopedic surgery with a chief complaint of sciatica on the lateral side of the right thigh. An abnormal vessel was pointed out and she was referred to our department. Enhanced CT showed the right persistent sciatic artery, type 2a of the Pillet-Gauffre classification, and its outer diameter was enlarged to 2.0 cm. The persistent sciatic artery communicated to the popliteal artery. The superficial femoral artery was hypoplastic and the profunda femoral artery was normal. VIABAHN was deployed into the persistent sciatic artery aneurysm from the right internal iliac artery to the upper third of the right thigh. The superior gluteal artery was preserved. After the procedure, she complained no sciatica. VIABAHN was patent and the aneurysm regressed without type II endoleak four years postoperatively.
