Endovascular revascularization of an occluded persistent sciatic artery for chronic limb-threatening ischemia in a patient with Coronavirus Disease 2019

A persistent sciatic artery (PSA) is a rare embryologic variant that usually presents with aneurysmal degeneration. This report describes a 66-year-old man with severe comorbidities who presented with right forefoot gangrene and severe acute respiratory syndrome coronavirus 2 infection. Imaging revealed a unilateral PSA with a chronic occlusion at the level of the knee joint with no aneurysm. After coronavirus disease 2019 resolution, he underwent CO2 angiography with successful recanalization of the PSA, followed by transmetatarsal amputation that healed uneventfully. At follow-up after 16 months, he was noted to have asymptomatic thrombosis of his stent and, hence, no intervention was performed.
