摘要

目的:描述一例先天性右颈总动脉(CCA)缺失伴左副大脑中动脉(MCA)的病例,并通过计算机断层血管造影(CTA)诊断。方法:一名63岁的女性,在磁共振成像中偶然发现右侧颈内动脉狭窄(ICA),接受CTA进一步血管评估。结果:CTA显示右侧颈外动脉缺失,右侧颈外动脉从头臂干分支,右侧颈外动脉从右侧锁骨下动脉分支。ICA发育不全。左副MCA也被观察到。虽然右ICA血流减少,但患者无症状;因此,给予保守治疗,她的临床过程保持平稳。结论:CCA缺失与主动脉发育及各种血管变异有关;然而,据我们所知,这是第一个与对侧附属MCA相关的报告,其存在可能被认为是偶然的。在考虑脑动脉瘤和其他动脉病变的血管内治疗时,术前了解这种罕见的变异是很重要的。

Absent right common carotid artery associated with left accessory middle cerebral artery diagnosed by computed tomography angiography.

Purpose: To describe a case involving congenital absence of the right common carotid artery (CCA) associated with a left accessory middle cerebral artery (MCA) that was diagnosed by computed tomography angiography (CTA).

Methods: A 63-year-old woman with a narrow right internal carotid artery (ICA) incidentally detected on magnetic resonance imaging underwent CTA for further vascular evaluation.

Results: CTA revealed absence of the right CCA, with the right external carotid artery (ECA) branching from the brachiocephalic trunk and the right ICA branching from the right subclavian artery. The ICA was hypoplastic. A left accessory MCA was also observed. Although blood flow in the right ICA was decreased, the patient was asymptomatic; thus, conservative treatment was administered, and her clinical course remained uneventful.

Conclusion: Absence of the CCA is associated with the development of the aorta and various vascular variations; however, to our knowledge, this is the first report of an association with a contralateral accessory MCA, the existence of which may be considered incidental. Preoperative knowledge of this rare variation is important when considering endovascular treatment of cerebral aneurysms and other arterial lesions.

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.
