[Damage to cranial and peripheral nerves following patency restoration of the internal carotid artery].
The aim of the study was an assessment of the incidence of injury to cranial and peripheral nerves as complication of patency restoration of the internal carotid artery, and analysis of the effect of peripheral nerve injury on the results of carotid patency restoration. From Oct 1987 to Sept 1999 543 procedures were carried out for restoration of patency of the internal carotid artery. After the operation hypoglossus nerve injury was found in 7 cases (1.4%), vagus injury in 9 (1.8%). Signs of exclusively recurrent laryngeal nerve damage were found in 6 cases (1.2%). Glossopharyngeus nerve was damaged in 2 cases (0.4%), transient phrenic nerve palsy as a result of conduction anaesthesia was noted in 2 cases (0.4%). Damage to the transverse cervical nerve was found in 96 cases (60%). In 2 patients (1.2%) lower position of mouth angle was due to section of the mandibular ramus of the facial nerve. In another 2 cases skin sensation disturbances were a consequence of lesion of the auricularis magnus nerve and always they coexisted with signs of transverse cervical nerve damage.


CONCLUSIONS
damage to the cranial nerves during operation for carotid patency restoration are frequent but mostly they are not connected with any health risks and often they regress spontaneously.
