Persistent sciatic artery presenting as recurrent hematomas: A case report

Abstract

The persistent sciatic artery (PSA) normally regresses during embryonic development; however, it can persist in some cases with an estimated frequency of 0.03 %. This rare case of PSA involved a 76-year-old woman with a history of right femoral fracture surgery, who experienced recurrent hematomas between her right buttock and thigh. Contrast-enhanced computed tomography revealed a complete, right-sided PSA, necessitating two-staged surgical intervention. Right femoropopliteal artery bypass surgery and popliteal artery banding were performed, followed by coil embolization of the PSA. A postoperative examination confirmed that the graft was receiving adequate perfusion without any PSA perfusion. Consequently, the patient was discharged without complications on the 14th postoperative day. Treatment of the persistent sciatic artery is contingent upon the individual's situation. Thoughtful consideration must be taken when deciding on surgical technique, in order to ensure minimal surgical invasiveness and optimal long-term outcomes.
