Absence of the common carotid artery in a patient with a persistent trigeminal artery variant
1Department of Diagnostic Radiology, Uppsala University Hospital, Uppsala, S-751 85, Sweden.
Abstract:
We found the present case when retrospectively reviewing the files of patients with intracranial aneurysm in our institution. It concerns the coexistence of a rare developmental anomaly of the aortic arch vessels and a persistent carotid-vertebrobasilar communication variant. Since no common embryologic basis is known, this association was probably fortuitous. Each of these particular anomalies can pose unique diagnostic and therapeutic difficulties.
