Özet
Objective: Injuries of cranial nerves such as vagus, hypoglossus and facial and peripheral nerves are sometimes reported in carotid surgery patients. In this study, we aimed to demonstrate the peripheral and cranial nerves injuries during carotid artery surgery in our patients with electrophysiological study which is an objective method. Method: In total of 18 patients, electrophysiological evaluation of bilateral cranial and peripheral nerves was performed with standard fashion one month after the carotid endarterectomy + patch plastic operation. Also, in these patients and in 20 healthy control subjects, R-R interval variability during quiet and deep breathing was measured for evaluation of vagal nerve. Findings: There were left carotid lesions in eleven patients (61 %) and patch-plasty had been performed with polytetrafluoroethylene in fifteen patients and saphenous vein graft in three patients following carotid endarterectomy. Any major complication such as perioperative stroke and mortality was not observed in all of the patients. Preoperatively suspected bilateral carpal tunnel syndrome was confirmed with electrophysiotogically in one patient. In postoperative period, partial facial nerve injury was detected in one patient (5,5%). Except this one, cranial and peripheral nerve injuries were not detected in remained patients who contain three patients with preoperative stroke remnant. There were not statistically significant differences in comparison of nerve conduction velocities and amplitudes of operation side and opposite side. There was not a statistically significant difference between the control group and carotid endarterectomy group in measurement of R-R interval variability during quiet and hyperventilation. Discussion: Carotid endarterectomy operation is usually performed for prevention of stroke, but it can sometimes cause some undesirable complications. Injury of the branches of facial nerve, vagal nerve and hypoglossus are frequently reported. In majority of the studies, nerve lesion is demonstrated with investigation of suspected patients with complaints. We were not found a study which all of the carotid endarterectomy patients were evaluated with electrophysiologically. In our study which contain of electrophysiological investigation of some cranial and peripheral nerves including the vagal nerve, we were observed only one partial facial nerve lesion. Conclusion: In extracranial carotid artery lesions, carotid andarterectomy operation can succesfully perform with carefully surgical dissection without any complication, although it can cause cranial and peripheral nerve complications which reported in literature.
