Abstract

Purpose: The vertical level of carotid bifurcation (CB) is commonly indicated at the superior margin of the thyroid cartilage. Few studies observed the CB vertical topography. It was aimed at studying the vertical location of the CB as referred to vertebral and anterior cervical landmarks.

Methods: An archived lot of 147 computed tomography angiograms was documented for the vertical level of CB referred to vertebral and anterior cervical landmarks. The topography of the CB in relation to anterior landmarks was classified into seven types: (1) at the superior margin of the thyroid cartilage; (2) between the hyoid and the thyroid cartilage; (3) at the hyoid level; (4) between the hyoid and mandible; (5) subgonial or supragonial CB; (6) lower cervical level; (7) intrathoracic.

Results: The most common locations of CB were at C3 (27.21%), C3/C4 (26.19%) and C4 (25.51%). Bilateral symmetry of CB was found in 51.7%, except for C2 and C5/C6. Type 7 was not found, type 3 occurred in 39.12%, type 2 in 24.49%, type 1 in 13.95%, type 4 in 13.61%, type 5 in 6.12%, and type 6 in 2.72% (294 CBs). Bilateral symmetry of anterior types was found in 59.86%. Statistically significant correlations were found between sex and both left and right types and vertebral levels of CB.

Conclusions: The vertical topography of the CB is highly variable and has sex-related specificity. This detail should be included in the teaching of anatomy. Surgeons and interventionists should better document the carotid anatomy on a case-by-case basis.

颈动脉分叉的垂直地形图--原始研究和综述。

目的：颈动脉分叉（CB）的垂直水平通常位于甲状软骨的上缘。很少有研究观察到颈动脉分叉的垂直地形。本研究旨在研究颈动脉分叉与椎体和颈椎前方地标的垂直位置：方法：对 147 张存档的计算机断层扫描血管造影照片进行记录，以了解 CB 与椎体和颈椎前方地标的垂直位置。CB与前方地标的地形分为七种类型：(1) 甲状软骨上缘；(2) 舌骨与甲状软骨之间；(3) 舌骨水平；(4) 舌骨与下颌骨之间；(5) 颌下或颌上CB；(6) 颈椎下水平；(7) 胸内：最常见的 CB 位置是 C3（27.21%）、C3/C4（26.19%）和 C4（25.51%）。除 C2 和 C5/C6 外，51.7%的 CB 为双侧对称。未发现第 7 型，第 3 型占 39.12%，第 2 型占 24.49%，第 1 型占 13.95%，第 4 型占 13.61%，第 5 型占 6.12%，第 6 型占 2.72%（294 个 CB）。59.86%的前部类型为双侧对称。性别与 CB 的左右类型和椎体水平之间存在统计学意义上的显着相关性：结论：CB 的垂直地形变化很大，并具有与性别相关的特异性。这一细节应纳入解剖学教学中。外科医生和介入医师应根据具体情况更好地记录颈动脉解剖。

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.
