摘要

目的：关于重复起源的大脑副前动脉（ACA）的报道很少。大脑副中动脉（MCA）与ACA联合开窗也很少见。方法：我们报告一例用磁共振血管造影（MRA）诊断的副MCA伴副MCA开窗的重复起源的病例。结果：一名25岁女性因头痛来我院就诊。行3-Tesla磁共振成像及MRA，包括部分最大强度投影及体积渲染图，显示前交通动脉发源于副ACA。副ACA近端有两肢。经过仔细评估，发现附件ACA的来源相同。MRA还显示左侧副MCA起源于左侧ACA近A1段和左侧ACA远A1段的开窗。结论：鉴别这些罕见的解剖变异需要仔细的影像学评估。在我们的病例中，MRA部分最大强度投影和体积渲染图像是有用的，可以更好地了解三维血管结构。虽然在我们的病例中没有观察到动脉瘤，但有这种解剖变异的患者应该仔细评估是否有相关的动脉瘤。

Accessory anterior cerebral artery of duplicate origin associated with accessory middle cerebral artery and anterior cerebral artery fenestration.

Purpose: There are few reports of an accessory anterior cerebral artery (ACA) of duplicate origin. The combination of accessory middle cerebral artery (MCA) and ACA fenestration is also rare.

Methods: We report a case of accessory ACA of duplicate origin associated with accessory MCA and ACA fenestration diagnosed by magnetic resonance angiography (MRA).

Results: A 25-year-old woman visited our hospital because of headaches. She underwent 3-Tesla magnetic resonance imaging and MRA, including partial maximum intensity projection and volume rendering images, which showed an accessory ACA originating from the anterior communicating artery. The accessory ACA had two limbs in its proximal portion. Careful assessment revealed a duplicate origin of the accessory ACA. MRA also showed a left accessory MCA arising from the left ACA proximal A1 segment and fenestration of the left ACA distal A1 segment.

Conclusion: Identification of these rare anatomical variants requires careful imaging assessment. In our case, MRA partial maximum intensity projection and volume rendering images were useful and provided a better understanding of the three-dimensional vascular architecture. Although no aneurysms were observed in our case, patients with such anatomical variations should be carefully assessed for associated aneurysms.

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.
