Abstract

OBJECTIVES: In this study, we evaluated early surgical results including 30 days early stroke and death rate and complications in 168 cases carotid endarterectomy (CEA).
METHODS
A retrospective review of patients who underwent CEA at our institute between September 1999 and August 2010 was done. Preoperative symptoms were stroke in 72 cases, transient ischemic stroke or reversible ischemic neurologic deficit in 56 cases and asymptomatic in 40 cases. Most of the patients had conventional cerebral angiography or neck computed tomography angiography (CTA) for preoperative evaluation. Immediate radiological follow up was performed by neck CTA 1 week postoperatively.
RESULTS
The overall postoperative stroke rate including transient ischemic attack within 30 days of the treatment was 1.7%. Major stroke rate with morbidity and death rate within 30 days was 0.6% (1 : major stroke, 1 : death). The cause of death was airway occlusion due to wound hematoma. Cranial nerve palsy developed in two patients (1.1%) and neck hematoma in six patients (3.5%). Neck CTA revealed total occlusion of internal carotid artery in one patient with acute cerebral infarction and then recovered fully. Intracranial hemorrhage relating to the hyperperfusion syndrome developed in one patient. Radiological patency rate was 98.7%. The comparison of 30 days morbidity and mortality rate between CEA and carotid angioplasty and stenting were each 0.6% and 1.5%, but there was no statistical significance.
CONCLUSIONS
Carotid endarterectomy provides considerable future risk prevention against stroke in patients with symptomatic and asymptomatic carotid stenosis.
