Abstract:
A persistent sciatic artery is a rare developmental anomaly which may predispose to a range of vascular complications. We report a 60-year-old woman presenting with right lower limb ischemia. Computed tomography angiography revealed an aneurysmal right-sided sciatic artery occluded by thrombus. An aberrant right subclavian artery and anomalous common carotid origins were also incidentally discovered. It is unknown whether an association exists between a persistent sciatic artery and other congenital arterial abnormalities. This is the first case report, so far as we are aware, describing both such arterial anomalies coexisting in a patient.
