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.

2023年8月8日 · PCA is divided into four segments, P1 to P4. The segments can be further categorized into deep and superficial segments or proximal and distal, respectively. P1 and P2 segments are deep segments. The P1 segment is between …

2023年10月30日 · Posterior cerebral artery (arteria cerebri posterior) 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 …

2023年8月1日 · There are five main segments of the PCA (developed by Krayenbühl and Yasargil): P1: The P1 segment is located within the interpeduncular cistern and courses from the termination of the basilar artery to the posterior communicating artery, passing over the oculomotor nerve (CN III).

The apparent origin of the PCA from the P1 segment is, in fact, directly related to the embryology of the basilar artery, which is formed by fusion of paired longitudinal neural arteries. The extent of fusion determines the length of the basilar, and some of its variations.

2018年7月30日 · An estimated 5-10% of ischemic strokes in the United States involve the posterior cerebral artery (PCA) or its branches. While stroke is the third leading cause of death in the United States...

本文提供大脑后动脉（pca）的分段图解，详细介绍了pca起自基底动脉后的供应区域，以及闭塞时的多种症状。 还阐述了PCA分4段，且有3种类型分支的相关知识。

Fenestration of the P1 segment of the PCA is of particular importance for neuro-intervention. The literature is well documented with cases of aneurysms within the PCA and specifically the P1 segment with concomitant fenestration. It is, therefore, important to be aware of anatomical variations in the artery, as presented in this case report.

2023年8月8日 · PCA is divided into four segments, P1 to P4. The segments can be further categorized into deep and superficial segments or proximal and distal, respectively. P1 and P2 segments are deep segments. The P1 segment is between …

2001年1月1日 · Aneurysms of the posterior cerebral artery (PCA) represent approximately 1% of all intracranial aneurysms . The surgical approach and dissection of the PCA is technically challenging owing to the complexity of its perforating branches and their intimate relationship with the cranial nerves and upper brain stem.
