Wound hematomas after carotid endarterectomy.

Wound hematomas, following carotid endarterectomy, are uncommon but potentially lethal complications. The management of 13 patients with this condition is presented. Factors that appeared to predispose to hematoma formation included perioperative use of platelet inhibitory drugs and postoperative hypertension. When the diagnosis of neck wound hematoma is made after carotid endarterectomy, prompt evacuation under local anesthesia is recommended.
