Published data suggest that the regional anesthetic technique used for carotid endarterectomy (CEA) increases the systolic arterial blood pressure and heart rate. At the same time local anesthesia reduced the shunt insertion rate. This study aimed to analyze risk factors and ischemic symptomatology in patients with postoperative internal carotid artery restenosis. The current retrospective study was undertaken to assess the results of CEA in 8000 patients who were operated during a five-year period in six regional cardiovascular centers. Carotid color coded flow imaging, medical history, clinical findings and atherosclerotic risk factors were analyzed. Among them, there were 33 patients (0.4%) with postoperative re-occlusion after CEA. The patients with restenosis were re-examined with carotid color coded flow imaging and data were compared with 33 consecutive patients with satisfactory postoperative findings to serve as a control group. In the restenosis group eight risk factors were analyzed (hypertension, smoking, hyperlipidemia, diabetes mellitus, history of stroke, transitory ischemic attack, heart attack and coronary disease), and compared with risk factors in control group. Study results suggested that early postoperative internal carotid artery restenosis was not caused by atherosclerosis risk factors but by intraoperative shunt usage.
