Abstract

Persistent sciatic artery (PSA) is an extremely rare vascular phenomenon, with a prevalence of 0.025% to 0.04% in the general population. We present the case of a 72-year-old man with a thrombus-containing PSA aneurysm that caused embolic acute limb ischemia. We also discussed the PSA classification systems, common presentations, rarity of the pathology, and high rates of severe complications.

Keywords: Acute limb ischemia; Aneurysm; Congenital; Persistent sciatic artery.
