Basilar artery fenestration (or more simply, basilar fenestration) is the most common intracranial arterial fenestration and most common congenital anomaly of the basilar artery. This anatomic variant is characterized by duplication of a portion of the artery that are connected proximally and distally. Epidemiology See more Its reported prevalence is highly variable depending on the technique used: 1. angiography: 0.6% 3 (presumably low due to preferential laminar flow in only one lumen at a time) 2. … See more An arterial fenestration is a segmental duplication wherein a single lumen divides into two lumens, both lined by endothelium, that rejoin to one distally. Fenestrations vary in size. At one extreme, basilar … See more The main differential consideration for a small fenestration is an acquired focal arterial dissectionwith a raised intimal flap dividing true and … See more Basilar fenestration is generally considered an anatomic variant not requiring observation or treatment.
