Objective: The necessity for an indwelling arterial shunt during carotid endarterectomy (CEA) is one of the most widely debated and long-standing controversies in carotid surgery. We developed a modified technique for carotid endarterectomy without using a shunt and have achieved successful results with this procedure. The aim of this study is to present these 352 isolated CEA cases and evaluate the results. Material and Methods: In our clinic, 352 isolated CEA were performed on 320 consecutive patients without using a shunt between 2005 and 2012. In 32 of the cases, bilateral CEA were performed. Among the patients, 36.8 % (n=118) were neurologically asymptomatic, and 63.2 % (n=202) were symptomatic. Complete occlusion was present in the contralateral carotid arteries of 23 patients. All patients were operated on under general anesthesia, and no intraluminal shunts were used. This operative technique is a modification of an eversion carotid endarterectomy in which a longitudinal arteriotomy is begun on the common carotid artery (CCA) and purposely skewed towards the origin of the external carotid artery. The mean crossclamp time in our study was 12±4.62 minutes. Results: There was one case of postoperative mortality (0.28%) that was caused by myocardial infarction. We observed 1 (0.28%) case of permanent neurologic deficit, 27 (7.6%) cases of peripheral nerve damage, 4 (1.1%) cases of early postoperative transient neurologic attack, 3 (0.85%) cases of hoarseness and 3 (0.85%) cases of neurocognitive impairment. Conclusion: The results indicate that this mini-modified eversion CEA surgery performed without the use of a shunt can be successful for patients with carotid stenosis.
