title: Hypertension following carotid endarterectomy.
abstract: Seventy-nine patients undergoing staged bilateral carotid endarterectomy were studied to determine the relationship of perioperative hypertension to postoperative neurologic deficits. Six of the eight neurologic deficits following 158 endarterectomies (5%) occurred after the first operation, all being temporary. Comparison of the mean blood pressures in patients with and without postoperative strokes revealed no statistically significant differences. Patients on antihypertensive medications were at a significantly higher risk of developing postoperative strokes. A trend towards higher blood pressure was noted following the second endarterectomy, particularly when they were staged more than 60 days apart. Based on our findings, a cautious approach is warranted in the treatment of postendarterectomy hypertension.
