Surgical treatment in symptomatic stenosis of the carotid artery and persistent primitive hypoglossal artery. / Khirurgicheskoe lechenie pri simptomnom stenoze sonnoi arterii i persistiruiushchei émbrional'noi pod''iazychnoi arterii.

Persistent primitive hypoglossal artery is a rare variant of intrauterine anastomosis between the carotid and basilar arteries, which may remain in adults. The presence of this artery in carotid artery atherosclerosis increases the risks for stroke in the carotid and basilar basins. Our clinical case illustrates successful carotid endarterectomy in the presence of an ipsilateral persistent primitive hypoglossal artery under cerebral oximetry control.
