Carotid Endarterectomy with Modified Eversion Technique: Results of a Single Center

Abstract

Carotid endarterectomy (CEA) has a wide range of approaches based on personal expertise and preference. We evaluated our outcome with CEA with modified eversion technique (meCEA) under local anesthesia and whether the surgeon's experience could influence it. at our Institution, 837 patients underwent CEA across 8years. Although the surgicaltechnique was standardized, 2 groups were considered further: meCEA performed by a single Senior Operator (Group A) and meCEA performed by 4 young Consultants (Group B). A selective shunting policy was needed in 5.1%, together with general anesthesia. Overall operative time was 63.9±15.1minutes (61.4±12.5 and 66±16.9minutes in Group A and Group B respectively; P<0.001) and cross-clamp time 19.3±2.9minutes (19.0±3.2 vs. 19.5±2.8, P=0.009). At 30days, 0.7% TIA and 0.8% strokes were recorded. No differences (p=N.S.) between the 2 study groups in terms of postoperative neurological complications, with postoperative ipsilateral strokes always<1%. At a median imaging follow-up of 22.5months, the overall percentage of restenosis was 3.7%, with no difference between the 2 groups (P=0.954). Twenty-two patients (2.6%) underwent reintervention for significant restenosis, and none of them had an ipsilateral stroke or TIA. Freedom from reintervention for restenosis at 24months was 97.9% in Group A and 95.9% in Group B, with no between-group difference (P=0.14). At the median survival follow-up of 37months, the overall survival rate at 24months was 97.9%in Group A, and 97.9% in Group B, with no between-group difference (P=0.070). In our experience, CEA with a modified technique is safe and achieves comparable outcomes to those of other established techniques. The reported short cross-clamp time, also in less experienced hands, is an additional strength.
