title: Delayed carotid pseudoaneurysm:  a life-threatening complication after endoscopic sinus surgery.
abstract: Internal carotid artery pseudoaneurysm is a rare but potentially lethal complication of sinus surgery. We present 2 cases of delayed carotid pseudoaneurysm development after internal carotid laceration during functional sinus surgery for chronic sinusitis to emphasize the need to follow up the patients with profuse bleeding perioperatively and to identify when to suspect iatrogenic vascular malformations.
