TIAGO, José et al. Lower limb ischaemia due to occlusion of a persistent sciatic artery aneurysm: a case report. []. , 8, 2, pp.70-72. ISSN 1646-706X.

Persistent sciatic artery is a rare embryological anomaly. The authors report the clinical case of a 81-year-old man presenting with a right lower limb ischaemia and a pulsatile mass in the buttock. Computed tomographic angiography demonstrated a complete and unilateral persistent sciatic artery, with an aneurysmal degeneration on its, proximal third. During the pre-operative workup, spontaneous aneurismal occlusion occurred, worsening the condition to a critical ischaemia. The patient underwent, successfully, a distal femoro-popliteal bypass. Review of the literature confirms the rarity of this anomaly, which is frequently associated to degenerative changes. Surgical repair is prompt recommended to prevent complications.
