A case of coexistence of multiple vascular anomalies including the absence of a left internal carotid artery, a left vertebral artery arising from the subclavian artery in a high cervical location, and a bovine arch associated with vertebral fusion

Abstract

We report a rare 16-year-old male case of Klippel-Feil anomaly associated with fetal alcohol syndrome exhibiting complex congenital vascular anomalies. The congenital vascular anomalies observed were the absence of a left internal carotid artery, a left vertebral artery arising from the subclavian artery in a very high cervical location and a bovine arch. The vascular and vertebral anomalies were evaluated using CT and MRI before cervical surgery.
