摘要

目的：椎动脉（VA）穿透硬脑膜，与硬脑膜内的 V4 段相连。进入硬脑膜后，椎动脉从髓质的内外侧上升到前上侧。关于 VA 压迫髓脊交界处（MSJ）的报道很少。因此，我们的目的是确定 AV 穿过 MSJ 的发生率：本研究记录了 162 份存档的 CT 血管造影档案。我们记录了 VA 穿过 MSJ 的病例。我们将 VA 评估为显性、非显性或共同显性：在 32 个病例（19.75%）中，我们在 MSJ 腹侧发现了硬膜内动静脉。在男性和女性中，这种动静脉畸形的发生率分别为 17.1%和 23.81%。在 32 个病例中，6 个病例的 VA 为非优势型，14 个病例为优势型，12 个病例为共优势型：MSJ上的VA病程并不罕见。因此，当发现 MSJ 或延髓受压的特殊神经体征时，应在 CT 或 MRI 血管造影中记录 VA 的走向。

Transverse and oblique course of the vertebral artery over the medullospinal junction.

Purpose: The vertebral artery (VA) pierces the dura mater and continues with the intradural V4 segment. Once entered into the dura mater, the VA ascends from the infero-lateral to the antero-superior side of the medulla. Scarce reports of VAs compressing the medullospinal junction (MSJ) are available. We therefore aimed to determine the incidence of a course of the AV over the MSJ.

Method: One hundred sixty-two archived CT angiogram files were documented in the study. We recorded the cases in which the VA crossed the MSJ. We assessed the VA as dominant, non-dominant or co-dominant.

Results: In 32 cases (19.75%), we identified intradural AVs on the ventral side of the MSJs. The incidence of this course of the VA was 17.1% in males and 23.81% in females. Of the 32 cases, the VA was non-dominant in 6, dominant in 14, and co-dominant in 12.

Conclusion: The VA course over the MSJ is not rare. Therefore, when specific neurological signs of MSJ or medulla compression are found, the course of the VA should be documented on CT or MRI angiograms.

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.
