"Duplication is said to occur when there are two vessels arising from the internal carotid artery instead of one. There are two distinct types depending on the pattern of insertion."
"There is no known association between duplication and the occurrence of aneurysms at the origin of the posterior communicating artery 1. Nonetheless, knowledge and identification of this type of variation is of importance during neurovascular surgery as the origin of the posterior communicating artery is a common site for cerebral aneurysm formation."
