A Case of Leriche Syndrome Affecting the Bilateral Renal Artery

Abstract

Leriche syndrome is defined as a chronic occlusive disease of the infrarenal aorta and the iliac axis. This syndrome slowly progresses proximally and distally overtime, but proximal progression to the suprarenal level is rare. We herein report a patient who presented with Leriche syndrome affecting the bilateral renal artery. A 36-year-old man was admitted to our institution with intermittent claudication and intractable hypertension. A blood chemistry analysis revealed some autoantibodies. A CT scan showed stenosis of the suprarenal aorta and occlusion from the juxtarenal aorta to the bilateral common iliac artery with occlusion of the right renal artery and severe stenosis of the left renal artery. We performed thromboendarterectomy of the juxtarenal aorta and bilateral renal artery under suprarenal aortic cross-clamping and bifurcated graft replacement. Thereafter, his intermittent claudication and hypertension improved. The histological findings showed thrombotic occlusion, while additionally anti-phospholipid antibody syndrome was suspected.
