A Case of Femoral Artery Compression Resulting from a Ganglion of the Hip Joint

Abstract

Cystic adventitial disease is a rare cause of arterial insufficiency. It usually affects the popliteal artery and its etiology is obsure. It has also been detected in the radial, ulnar, external iliac and common femoral vessels. Here, we describe a case of cystic compression of the common femoral artery from a ganglion arising from the hip joint. A 50-year-old healthy man presented with claudication for several years, rapid left leg cool feeling and numbness. In the left lower limb, the ankle brachial pressure index was as low as 0.31, and three-dimentional computed tomography showed occlusion of the left femoral artery. Left femoral arterial echocardiography suspected thrombosis at the same site. Primary diagnosis was left femoral arterial thrombosis and thrombectomy was performed. However, there was no thrombus and also blood flow was normal. About fifty days later, same symptoms recurred and re-stenosis was occurred. The findings of magnetic resonance imaging suggested the presence of cyst formation of the femoral arterial wall. We performed resection of the left common femoral artery and graft replacement. Arterial compression due to external cystic lesions, this case caused by Ganglion, although rare, was recognized. This case serves as a reminder that the causes of rapid ischemic symptoms, and cystic adventitial disease should be considered in the diagnosis of all patients.
