Abstract

PURPOSE
Potential benefits of eversion carotid endarterectomy (eCEA) compared with conventional carotid enderterectomy (cCEA) are more simple and faster reanastomosis with a low risk of restenosis. However, in Korea, eCEA is not popular having only one report of eCEA. This study aimed to investigate the results of eCEA.
METHODS
From July 2008 to September 2010, authors performed 36 eCEAs for patients with carotid artery stenosis in our hospital. Patients' demographics and clinical data were retrospectively reviewed. Regarding early (<30 days) results including the frequency of postoperative stroke, myocardial infarction, cerebral hyperperfusion syndrome, bleeding, cranial nerve palsy, new brain lesions (NBLs) on diffuse-weighted MRI (DW-MRI) and mortality were examined. Mid-term results such as stroke, death and restenosis after over thirty days were also examined.
RESULTS
Mean age was 66.6 years old and 88.9% of the patients were male. Twenty-four patients (66.7%) had a previous neurological event in the preceding 6 months. A carotid shunt was used in 3 cases (8.3%) and mean carotid clamping time was 25.4 minutes. One case (2.8%) of non-disabling ipsilateral stroke, 1 case (2.8%) of wound hematoma and 1 case (2.8%) of cranial nerve palsy developed after operation. DW-MRI was conducted in 27 patients (75.0%) and NBLs were detected in 4 patients (11.1%). One case (2.8%) of restenosis was discovered during the follow-up period (mean, 9.0 months), and there were no strokes or death.
CONCLUSION
Early and mid-term postoperative stroke and complication rates of eCEA were acceptable in our series. However, to assess efficacy of eCEA, further large-volumed and long-term follow-up studies are needed.
