Abstract

Purpose: To describe a case of true fenestration of an extremely long anterior communicating artery (ACoA).

Methods: A 3-year-old boy with a history of a ventricular septal defect and aortic coarctation underwent magnetic resonance imaging (MRI) and angiography (MRA) of the head and neck regions using a 3-Tesla scanner, for follow-up of stenosis at the origin of the innominate artery, which was a complication of aortic arch coarctation surgery.

Results: MRA of the head region showed an extremely long ACoA of approximately 20 mm in length, with a fenestration of approximately 5 mm in size. No aneurysms were observed.

Conclusion: According to a meta-analysis, the mean length of the ACoA was 2.84 mm (0.38-10.4 mm). The ACoA has been reported to be the most frequent site of fenestration of intracranial arteries. However, most reported ACoA fenestrations are not true fenestrations, but duplications or partial duplications. We herein report a case of true fenestration of an extremely long ACoA, which is an extremely rare variant. To our knowledge, this is the first report of such an association in the relevant English language literature.

磁共振血管造影诊断的超长前交通动脉真开窗。

目的：报告一例超长前交通动脉（ACoA）真开窗。方法：1例3岁男童，有室间隔缺损和主动脉缩窄病史，采用3-Tesla扫描仪对其头部和颈部区域进行磁共振成像（MRI）和血管造影（MRA），随访主动脉弓缩窄手术并发症无名动脉起源狭窄。结果：头部区域MRA显示极长ACoA，长约20mm，开窗约5mm。未见动脉瘤。结论：meta分析显示，ACoA的平均长度为2.84 mm （0.38-10.4 mm）。据报道，ACoA是颅内动脉开窗最常见的部位。然而，大多数报告的ACoA开孔不是真正的开孔，而是重复或部分重复。我们在此报告一个病例的真正开窗的一个极长的ACoA，这是一个非常罕见的变种。据我们所知，这是相关英语文献中首次报道这种关联。

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.
