[Internal carotid artery injury during endoscopic endonasal surgery: 3 cases report].

Three cases of internal carotid artery (ICA) injury during endoscopic endonasal surgery were analyzed, including 1 case of recurrent malignancy of sphenoid sinus, 1 case of intraorbital meningioma and 1 case of optic neuropathy. Salvage sphenoid sinus packing with gauze strip was managed in all the three cases. One patient operated a permanent closure of the carotid system intraoperatively and died after surgery. Among 2 survival cases, one patient accepted the endovascular embolization subsequently; the other patient was cured by intravaseular stent graft implantation without craniocerebral or ocular complicatitms.
