Description: Aug 20, 2023 · The posterior communicating artery (PCOM) is a part of a group of arteries in the brain known as the circle of Willis. The artery connects the internal carotid and the posterior cerebral arteries. Its role is to provide blood supply to the brain. The posterior communicating artery is a location where aneurysms can potentially occur.

Description: Nov 3, 2023 · The posterior communicating artery (PComm) is a branch of the internal carotid artery that participates in the cerebral arterial circle of Willis. The posterior communicating artery connects the internal carotid with the posterior cerebral arteries, thus connecting the anterior and posterior cerebral circulations.

Description: PCOM / Superior Hypophyseal Artery Balance. There is a balance between these two that is rarely discussed. Here, the superior hypophyseal artery is hypoplastic — very tiny actually. The supply of its territory is from a branch of the PCOM (arrows) STEREO PAIRS. AXIAL DYNA IMAGES — the hypoplastic superior hypophyseal is dashed arrow.

Description: The PComA connects the anterior and posterior circulation. It can in fact be understood as the most cranial of the carotid-basilar anastomoses. 25 When the proximal PCA (P1 segment) is hypoplastic or absent, the PComA serves as the only or dominant source of blood supply to the PCA territory.

Description: Aug 20, 2017 · Introduction. A posterior communicating artery (PcomA) aneurysm is located in only the proximal portion of the PcomA, which is usually incorporated in the aneurysm. Depending on the configuration of the aneurysm and the PcomA, it is sometimes difficult to preserve PcomA patency surgically or endovascularly.

Description: Feb 21, 2024 · A fetal posterior communicating artery (PCom) describes a situation whereby the PCom is larger than the P1 segment of the posterior cerebral artery (PCA) and thus, supplies the bulk of the blood to the PCA 4,5. In this setting, the P1 can be small (hypoplastic) or absent.
