Abstract

The cerebral arterial circle is susceptible to various developmental anomalies that may persist in adulthood. Notably, the persistent primitive olfactory artery (PPOA) is a rare variation, with a reported prevalence of 0.14%, and it is infrequently paired with other vascular anomalies. This imaging report details a unique instance involving a 65-year-old male patient presenting a rare combination of a left-sided PPOA, a left-sided accessory middle cerebral artery (AMCA), and an early bifurcation of the anterior cerebral artery (ACA). The arterial variations were identified utilizing computed tomography angiography (CTA). The PPOA, characterized by its distinctive hairpin turn and nasal branch, runs parallel to the A2 segments, while the AMCA emerges as an anomalous branch from the ACA. Comprehending such configurations is essential for preoperative planning in anterior skull base surgeries due to the associated risks of aneurysm formation and potential intraoperative complications. This case underscores the significance of recognizing rare vascular anomalies to mitigate surgical risks and enhance patient outcomes.

持久原始嗅动脉、附属大脑中动脉和早期分叉的大脑前动脉共同存在。
脑动脉圈易受各种发育异常的影响,这些异常可能持续到成年。值得注意的是,持久性原始嗅动脉(PPOA)是一种罕见的变异,据报道患病率为0.14%,并且很少与其他血管异常配对。本影像学报告详细介绍了一名65岁男性患者的独特病例,表现为罕见的左侧PPOA、左侧附属大脑中动脉(AMCA)和早期大脑前动脉(ACA)的合并。利用计算机断层血管造影(CTA)确定动脉变异。PPOA以其独特的发夹弯和鼻支为特征,平行于A2段,而AMCA则作为ACA的异常分支出现。由于相关的动脉瘤形成风险和潜在的术中并发症,了解这种结构对于前颅底手术的术前规划是必不可少的。本病例强调了识别罕见血管异常对于降低手术风险和提高患者预后的重要性。

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.
