Eversion endarterectomy versus open thromboendarterectomy and patch plastyfor the treatment of internal carotid artery stenosis

Objective: in 1996 we changed our treatment for stenosis of the internal ca rotid artery (ICA) from open thromboendarterectomy and PTFE-patch plasty (T EA) to eversion endarterectomy (EEA). Design: retrospective study. Methods: a total of 475 EEAs of the ICA were performed between 2/96 and 11/ 96. These results were compared to the results of TEA carried out between 2 /94 and 11/94 (n = 388). Results: clamping and operation time were significantly shorter for EEA. Ne urological complications included transient ischaemic attacks in 1.0% in th e EEA group versus 1.3% after TEA (p = 0.72), minor strokes (0.6% vs. 1.8%, p = 0.10) and major strokes in 1.5% versus 1.1% (p = 0.59). The rate of re stenosis >50% was 2.5% after EEA and 10.2% after TEA. The only detectable d ifference of statistical significance in complication rates was in the lesi ons of the hypoglossal nerve (5.3% vs. 2.6%, p = 0.04). Conclusions: EEA of the ICA is a safe procedure for carotid reconstruction with the additional advantages of short clamping time, possibility of simul taneous shortening of an elongated ICA, and no requirement for patching.
