Abstract

Purpose: The association of bilateral duplication of the superior cerebellar artery with an origin from the posterior cerebral artery is rare but of great interest to anatomists, radiologists, and surgeons. This article reports bilateral duplicated hypoplastic superior cerebellar arteries, one of which arises from a full-type fetal cerebral artery.

Material and method: A 59-year-old woman admitted to the neurosurgery department for a subarachnoid hemorrhage underwent a brain CTA with 3D reconstruction using «3D slicer 4.11» software. Brain CTA and the 3D model were used to analyze the configuration of the posterior circulation.

Results: CTA images and the 3D model showed an unusual configuration of the posterior circulation. The basilar artery prolonged the left vertebral artery, while the right vertebral artery ended in the right posterior inferior cerebellar artery. On both sides, a full-type fetal posterior cerebral artery and duplicated hypoplastic superior cerebellar artery were observed. Three cerebellar arteries arose from the basilar artery, while the fourth one emerged from the right fetal posterior cerebral artery.

Conclusion: Knowledge of such a configuration of the posterior circulation and others is necessary before radiological and surgical procedures. It helps to understand hemodynamic events, and neurovascular conflicts, improve revascularization procedures, and avoid surgical arterial and nervous injuries.

双侧重复发育不全的小脑上动脉，其中一条起源于完整型胎儿大脑后动脉。

目的：小脑上动脉双侧重复与大脑后动脉起源的相关性很少见，但解剖学家、放射科医生和外科医生对此非常感兴趣。本文报道了双侧重复发育不全的小脑上动脉，其中一条起源于全型胎儿大脑动脉。材料和方法：一名因蛛网膜下腔出血入住神经外科的59岁女性使用«3D切片器4.11»软件进行了脑部CTA三维重建。脑CTA和三维模型用于分析后循环的结构。结果：CTA图像和三维模型显示后循环结构异常。基底动脉延长左椎动脉，而右椎动脉终止于右小脑后下动脉。两侧观察到完整型胎儿大脑后动脉和重复发育不全的小脑上动脉。三条小脑动脉来自基底动脉，第四条来自胎儿右侧大脑后动脉。结论：在进行放射学和外科手术之前，有必要了解这种后循环结构和其他结构。它有助于了解血液动力学事件和神经血管冲突，改进血运重建程序，避免手术中的动脉和神经损伤。

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.
