Reperfusion seizures after innominate endarterectomy.

Seizures occurring after carotid revascularization are an uncommon complication that has received increasing recognition. The development of postoperative seizures has been estimated to occur in 0.4% to 1.0% of all carotid endarterectomies. Patients with high-grade carotid arterial stenoses appear to be at highest risk for postoperative seizures, which are thought to be due to cortical hyperperfusion states. We report two cases of focal motor seizures occurring after innominate endarterectomy, demonstrating that this complication is not limited to carotid arterial surgery.
