[Ishiadic hernia (sciatic hernia)].

The sciatic hernia is a protrusion of the peritoneal sac and its contents through the great or small sciatic foramen. This kind of hernia is an extremely rare. The authors present patient with ischiadic hernia and its operative repair. The preoperative diagnosis was a tumour (cyst) localized intraglutealy, but during operation sciatic hernia was found. Hernia was operatively removed making an oblique incision over the palpable mass, splitting the gluteous maximus, and exposing and opening the hernial sac, avoiding nerve and vascular injury by careful dissection of the sac. Then the sac was ligated and excised. Closing of the musculature defect was made with interrupted sutures of 000-Dexon, aproximating the gluteus maximus and medius muscles to the musculus piriformis. The authors consider that transgluteal approach has priority to transabdominal approach.
