Case Report: Aneurysm of the Posterior Communicating Artery Itself

Report of a Successfully Treated Case

Abstract

Most of the so-called posterior communicating artery aneurysms actually originate at the internal carotid-posterior communicating artery junction. The incidence of aneurysms arising solely from the posterior communicating artery itself is reported to be 0 to 3.3% of the total cases. A 28-year-old female was the only case who had an aneurysm originating at the posterior communicating artery itself in a total of 1, 080 saccular aneurysm cases managed at our clinic. In this case, trapping the aneurysm in the posterior communicating artery was performed.
