A Large Recurrent Pseudoaneurysm of the Superficial Femoral Artery: A Case Report

Peripheral arterial aneurysms are rare vascular pathologies characterized by dilation of all 3 arterial wall layers within an extremity. When a peripheral aneurysm ruptures, the extravasation can be contained by the surrounding soft tissues of the extremity, forming a pseudoaneurysm that can continue to grow. This patient case involves a 60-year-old man, who presented with a ruptured left superficial femoral artery (SFA) aneurysm that formed a large recurrent pseudoaneurysm, with concomitant right SFA and popliteal artery aneurysms. Multiple diagnostic imaging techniques (eg, computed tomographic angiography, angiography, and sonography) and treatment methods (eg, autologous vein bypass and endovascular stent) were used throughout this patient’s care. This case is unique for its inherent comparison between aneurysms of the patient’s 2 lower extremities regarding timing of intervention (ie, before vs after aneurysm rupture) and type of intervention.
