2023年8月8日 · Identify the signs and symptoms that may be caused by a posterior cerebral artery stroke based on location and severity of the regions of diminished perfusion. Describe the components of stroke evaluation.

2024年9月29日 · The posterior cerebral artery curls around the cerebral peduncle to provide supply to the tegmentum and majority of the midbrain (excluding the crus cerebri). Branches of PCOM, P1 and P2 supply the thalamus.

The posterior cerebral artery (PCA) is one of a pair of cerebral arteries that supply oxygenated blood to the occipital lobe, as well as the medial and inferior aspects of the temporal lobe of the human brain. The two arteries originate from the distal end of the basilar artery, where it bifurcates into the left and right posterior cerebral ...

2023年10月30日 · The posterior cerebral artery is a terminal branch of the basilar artery. It mainly supplies the occipital lobe , the inferomedial surface of the temporal lobe , midbrain , thalamus and choroid plexus of the third and lateral ventricles .

The patient underwent MT and subsequent angiography showed left PCA P2 segment occlusion was recanalized after MT. Outcomes: The patient's symptoms improved completely after MT. Conclusion: The clinical symptoms due to PCA P2 segment occlusion may be mistaken clinically for MCA stroke syndrome, which may lead to severe functional deficit.

A proximal occlusion of the posterior cerebral artery (PCA) can affect patients severely and clinical outcome might be poor. Aim of this paper is to describe clinical presentation, diagnostic findings and outcome of patients suffering from ischemia in the PCA territory.

Magnetic resonance imaging (MRI) showed a left hippocampal acute ischemic stroke with left PCA occlusion in the P2 segment. Despite a low National Institutes of Health Stroke Scale (NIHSS) score and the already-formed lesion in the hippocampus, successful stent retriever thrombectomy was performed due to a considerable perfusion–diffusion ...

2020年10月1日 · Magnetic resonance angiography (MRA) showed a signal defect in the left PCA (Figure 1D), and gradient echo T2∗ imaging showed the susceptibility vessel sign (SVS) in the P2 segment of the left PCA (Figure 1C) with a length of 9.8 mm. An ischemic penumbra was suspected because of DWI-FLAIR mismatch on magnetic resonance imaging.

2018年7月30日 · Posterior cerebral artery (PCA) stroke is less common than stroke involving the anterior circulation. An understanding of PCA stroke phenomenology and mechanisms requires...

The left PCOM (red) is transiently retrogradely opacified by the force of the injection. The portion which curves around the brainstem is the “P2”. Anything distal is P3, P4, and on. Because of the fetal disposition on the right, the lateral allows for left PCA view without superimposition.
