title: Dissecting aneurysms of posterior communicating artery itself: anatomical, diagnostic, clinical, and therapeutical considerations.
abstract: Posterior communicating artery (PCoA) itself is an unusual location for intracranial aneurysms in that isolated dissections or dissecting aneurysms are extremely rare. In the way of correct diagnosis of dissecting aneurysms of PCoA itself, a proper understanding of (1) the anatomy of the PCoA and its perforator branches, (2) some particular diagnostic features, and (3) related clinical aspects is of significant importance. Although there are no established treatment strategies for this particular type of aneurysms, the endovascular approach might be considered as a plausible one. In this paper, our scope was to report five cases with dissecting aneurysm of the PCoA itself and to discuss this rare vascular pathology from anatomical, diagnostic, clinical, and therapeutical perspectives.
