Abstract

Purpose: Fenestrations of posterior cerebral artery are exceedingly rare and, therefore, deserve being reported.

Methods: During an educational dissection, a peculiar anatomical variant of the posterior cerebral artery (PCA) was found.

Results: During an educational dissection targeting the right cerebellopontine angle, a peculiar variant of the right PCA was found. The respective posterior communicating artery inserted posteriorly into the junction of the P1 and P2 segments of the PCA. The P1 segment was thinner than the P2 segment. That junction was superior to the oculomotor nerve and was fenestrated, with a thin postero-medial arm facing the cerebral peduncle, and a larger antero-lateral arm formed by the distal end of the P1 segment and the proximal end of the P2 segment.

Conclusions: To the authors' knowledge, fenestrated P1-P2 junctions of PCA were not found previously by dissection. The evidence presented here recommends such variations not to be ignored.

在P1和P2节段交界处的大脑后动脉开窗术。

目的：大脑后动脉开窗术极为罕见，因此值得报道。方法：在一次教育性解剖中，发现了一种特殊的大脑后动脉（PCA）解剖变异。结果：在针对右侧桥小脑角的教育性解剖中，发现了右侧PCA的一种特殊变体。相应的后交通动脉向后插入PCA的P1和P2段的交界处。P1节段比P2节段薄。该连接点位于动眼神经上方，并且是开窗的，有一个面向脑蒂的细后内侧臂，以及一个由P1段的远端和P2段的近端形成的较大的前外侧臂。结论：据作者所知，以前未通过解剖发现PCA的开窗P1-P2连接。这里提供的证据建议不要忽视这些变化。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
