2023年7月28日 · The posterior communicating artery (PCom) makes up the posterior linkage in the circle of Willis.

2024年6月20日 · A fetal (origin of the) posterior cerebral artery (fetal PCA), sometimes also referred to less accurately as fetal (origin of the) posterior communicating artery (fetal PCom), is a common variant in the posterior cerebral circulation. Fetal PCAs occur in …

A left sided PCOM aneurysm is seen. Bilateral fetal PCOM can be seen also. otherwise the anatomy of circle of Willis is conventional. No evidence of subarachnoid bleeding (on FLAIR).

We performed magnetic resonance imaging (MRI) with and without contrast material and magnetic resonance angiography (MRA) of the circle of Willis in 16 patients with SD and 48 controls subjects matched for age and sex in order to determine the possible correlation between the absence of Pcom and SD.

2024年11月11日 · The posterior communicating artery (PCOM) is a small artery in the brain that connects the internal carotid and the posterior cerebral arteries. Its main purpose is to provide an alternative blood supply route to the brain in instances where the internal carotid or posterior cerebral arteries are blocked.

To test the hypothesis that different configurations of the ICA and PCOM arteries in relation to the location of the aneurysm can have important effects on intra-aneurysmal hemodynamics and, consequently, on aneurysm rupture, all PCOM aneurysms were classified into a set of angioarchitecture types presented in Fig 2. Aneurysms in type 3 were ...

2023年10月30日 · A PCom aneurysm, short for Posterior Communicating Artery aneurysm, is a weak, bulging area in the blood vessel (aneurysm) located in the brain. Specifically, it occurs on the posterior communicating artery, which plays a vital role in supplying blood to the brain.

Isolated third nerve palsy can be the sentinel sign of an aneurysm at the junction of the internal carotid artery and posterior communicating artery (PCom A), and evaluation of isolated third nerve palsies remains one of the most challenging situations in neuro-ophthalmology. 1–9 Expert interpretation of modern noninvasive neuroimaging such ...

2022年6月1日 · Information of the patients, the aneurysms and Pcoms, the initial treatment, and angiographic outcomes were collected. The IC-Pcom aneurysms were divided into Pcom-incorporated when their neck mainly rode on the Pcom or non-Pcom-incorporated when their neck mainly rode on the internal carotid artery or the classification was equivocal.

2020年7月7日 · We represent our experiences in the treatment of posterior communicating artery (PCOM) aneurysms by FD devices aiming to assess its angiographic efficacy (complete aneurysm occlusion) and its related complications. This is a retrospective study of 47 patients harboring 47 PCOM aneurysms treated with Pipeline Embolization Device (PED).
