Persistent sciatic artery (PSA) is a rare anatomic variant and is normally clinically silent. It can be found occasionally during uterine arteries embolization (UAE) and can lead to technical failure or complications. The authors present a patient with bilateral PSAs who was referred for emergency UAE because of uncontrollable postabortion hemorrhage. Inadvertent embolization of the right PSA led to unsalvageable ischemia and amputation of the right lower limb 12 days later.
