Angioplasty of the anterior tibial artery through an incidentally discovered persistent sciatic artery

Abstract

The persistent sciatic artery (PSA) is a rare arterial variant. Patients may present with a spectrum of atherosclerotic disease, but aneurysm formation with thromboembolic complications is more common. Although no intervention is required for asymptomatic individuals, stenting for stenosis, thrombolysis for occlusion and even utilisation of the PSA for intrapelvic embolisation have been reported. Angioplasty via an incidentally discovered PSA has rarely been described.
