Triple case report of persistent sciatic artery in Ethiopia: a rare vascular anomaly

Abstract

Abstract Persistent sciatic artery (PSA) is a rare congenital vascular anomaly resulting from embryologic axial artery malformation in the lower limb. This case report presents three patients aged 45–60, each with bilateral PSA presenting with symptoms indicative of PSA complications, including aneurysmal degeneration, limb ischemia, thromboembolism, or neuralgia from nerve compression. It highlights the diagnostic process, management strategies, and clinical outcomes observed at a tertiary referral hospital. Treatment involved a collaborative, multidisciplinary approach with vascular surgeons, internists, and radiologists tailoring interventions to individual patient findings and disease progression. This report aims to provide insights into the diverse presentations and management of PSA in a resource limited setting, encouraging further reporting and case studies to enhance understanding of therapeutic outcomes.
