Abstract

Peripheral arterial aneurysms are rare vascular pathologies characterized by dilation of all three 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. In this case report, a 60-year-old male 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 imaging modalities (computed tomography angiography (CTA), angiography, ultrasound) and treatment methods (autologous vein bypass, endovascular stent) were used throughout this case. This case is unique for its inherent comparison between aneurysms of the patient’s two lower extremities regarding timing of intervention (before vs after aneurysm rupture) and type of intervention (bypass vs stent). A brief discussion of the patient’s uninsured status is considered in light of the timing of treatment and outcome.
