Spontaneous Resolution of Lower Extremity Hypoperfusion in Type B Aortic Dissection: A Case Report

Abstract

Lower extremity hypoperfusion occurs in 5.7-30% of Stanford type B aortic dissection cases. A 53-year-old male patient presented with type B aortic dissection. His left femoral pulse was not palpable. The proximal left common iliac artery was nearly occluded in computed tomography angiography. There was no extremitythreatening rest pain, but there was intermittent claudication at 100 meters. Cross femoral bypass was planned for the patient under elective conditions. After two months, the left femoral pulse was palpable, and the patient no longer had intermittent claudication. In this study, we report that lower extremity hypoperfusion, which developed after acute type B aortic dissection resolved without open and endovascular surgery.
