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 ...

Intracranial aneurysms are common, and the risk of rupture is influenced by size, location, morphology, and factors such as ...

A 72 year-old woman developed the abrupt onset of difficulty seeing on the right side. Posterior Cerebral Artery (PCA) Infarction: Axial CT scans 3 days after presentation. Note the hypodensity in the ...

An embolus from the vertebral artery had migrated through the basilar artery to occlude the right posterior cerebral artery. Magnetic resonance imaging showed an occipital-lobe infarct (Panel B).

The basilar artery typically bifurcates into two posterior cerebral arteries (PCA) (Figure 1). The PCAs supply the occipital lobes and portions of the temporal lobes. Proximally, these arteries ...

The thalamus is supplied with blood by four branches of the posterior cerebral artery, namely the polar artery, paramedian thalamic-subthalamic arteries, thalamogeniculate arteries and the ...

Left: CT angiogram showing an aneurysm of 2 mm maximum diameter on the left posterior cerebral artery (arrow). Right: volume-rendered 3D reconstruction image. The aneurysm was missed in the initial ...

including the posterior cerebral artery (PCA), superior cerebellar artery (SCA), anterior inferior cerebellar artery (AICA) and basilar artery (BA). In this study, cerebral angiography was ...

Posterior Cerebral Artery (PCA) Infarction: Diffusion-weighted MRIs. Note the bright signal in the distribution of the right posterior cerebral artery. This syndrome is most often caused by a cardiac ...
