Info
A vascular structure is observed connecting the cervical segment of the left internal carotid artery at the C1-C2 level with the basilar artery. Bilateral vertebral arteries are poorly developed.
No vascular occlusions are observed. The non-contrast CT and perfusion study were normal.
Case Discussion
This vascular structure is consistent with a persistent hypoglossal artery, the second most common type of persistent carotid-vertebrobasilar anastomoses.
The patient was treated with rTPA and was discharged without symptoms after 3 days.
