Abstract

Purpose: Ponticulus Posticus, atlantooccipital ligament ossification-induced anomaly, surrounds the vertebral artery and the first cervical nerve root. It is believed to wrap around the first cervical nerve root and the vertebral artery, causing compression. We hypothesized that it would also reduce the diameter of the vertebral artery.

Methods: Between January 1, 2022, and December 31, 2022, cervical spine CT scans taken for any reason were retrospectively reviewed. The images of 1365 patients suitable for evaluation were evaluated by two expert radiologists in 3 dimensions. Among patients with PP, those who underwent cervical angiography were identified for vertebral artery diameter measurement.

Results: The average age of the 1365 individuals included in the study (732 males, 633 females) was 55.78 (± 18.85) with an age range of 1-96. Among this group, PP was detected in 288 individuals, resulting in a total prevalence of 21.1%. Right and left vertebral artery diameters were significantly lower in patients with complete PP compared to the absent group (p < 0,001, p < 0,001, respectively). Additionally, it was observed that width and height diameters and artery diameters were positively correlated in patients with Complete PP.

Conclusions: Ponticulus posticus can cause vertebrobasilar insufficiency by reducing the diameter of the vertebral artery. Therefore, imaging and detailed evaluation of this region are important in symptomatic patients.

椎体后凸会影响椎动脉直径吗？

目的：Ponticulus Posticus 是寰枕韧带骨化引起的异常，围绕着椎动脉和第一颈神经根。据认为，它包裹着第一颈神经根和椎动脉，造成压迫。我们假设它还会缩小椎动脉的直径：方法：回顾性审查了 2022 年 1 月 1 日至 2022 年 12 月 31 日期间因任何原因进行的颈椎 CT 扫描。两位放射科专家对 1365 名适合进行评估的患者的图像进行了三维评估。在 PP 患者中，对接受颈椎血管造影术的患者进行了椎动脉直径测量：参与研究的 1365 人（男性 732 人，女性 633 人）的平均年龄为 55.78（± 18.85）岁，年龄范围为 1-96 岁。其中，288 人检测出 PP，总患病率为 21.1%。与无PP组相比，完全PP患者的左右椎动脉直径明显较低（P 结论：完全PP患者的左右椎动脉直径明显低于无PP组：椎体后凸可通过减少椎动脉直径导致椎-基底动脉供血不足。因此，对有症状的患者进行该区域的成像和详细评估非常重要。

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.
