Modified Eversion Carotid Endarterectomy (mECEA): Analysis of Clinical and Financial Outcomes

Several carotid endarterectomy techniques have been described, including conventional carotid endarterectomy (CCEA) performed with patch repair and eversion carotid endarterectomy (ECEA) performed with transection of the internal carotid artery. We describe our simplified technique of modified eversion carotid endarterectomy (mECEA) with longitudinal arteriotomy limited to the carotid bulb, without transection of the internal carotid artery and present our analysis of its safety, efficacy, and cost effectiveness.

A retrospective review of all carotid endarterectomies performed by 3 vascular surgeons over a 3-year period was completed. About 197 mECEA were performed during the study period. Follow-up data were obtained on 77.7% of patients. A comparison was made with the contemporary literature with respect to outcomes for both CCEA and ECEA.

Between January 2012 and December 2014, a total of 197 mECEA were performed. The perioperative stroke and death rates for those undergoing mECEA was 0.5% and 0.5%, respectively. Late stroke and death rates were 3.0% and 5.1%, respectively. Perioperative rate of myocardial infarction was 1.0%. Early restenosis rates of >70% occurred in 1.4%, whereas late restenosis of >70% occurred in 2.7%. Mean operating time for those undergoing mECEA was 57.9 min. Average costs savings for mECEA compared to CCEA were $5,835.

This simplified technique has comparable outcomes to those described in the contemporary literature for both CCEA and ECEA with respect to postoperative neurologic events as well as restenosis rates. In our institution, the short mean operative times with mECEA has led to reduced resource utilization.
