AI Article Synopsis
- - Persistent proatlantal artery type 1 is an uncommon vascular connection between the carotid and vertebrobasilar systems, representing a rare embryonic anastomosis.
- - The case discussed involves bilateral persistent proatlantal arteries, originating from the internal carotid arteries and entering the skull through the foramen magnum to connect with vertebral arteries.
- - The text also explores the embryological background, clinical implications, and key differences between the two types of proatlantal arteries.
Article Abstract
Persistent proatlantal artery type 1 is one of the four anastomotic vessels between the carotid and vertebrobasilar arterial systems. Persistence of this embryonic anastomosis is extremely rare. We present such a case with bilateral persistent proatlantal arteries that arose from internal carotid arteries, entered the skull via the foramen magnum and united with the horizontal portions of vertebral arteries. We also mention its embryology, potential clinical implications, and differentiating features between two types of proatlantal arteries.
