Acute limb ischaemia due to thrombosed persistent sciatic artery aneurysm presents a surgical challenge in a frail octogenarian.



Persistent sciatic artery (PSA) is a rare congenital anomaly, whereby the embryonic sciatic artery remains patent with associated degrees of femoral axis hypoplasia.

Revascularisation strategies include embolectomy, bypass or interposition grafting and catheter-directed thrombolysis.
