Abstract：
METHODS: A descriptive, quantitative cross-sectional study of the atlantic part (V3) of the vertebral artery (VA).
OBJECTIVE: This study aimed to bridge the research gap in the morphometry of the V3 segment of the VA in the South Indian population.
BACKGROUND: The microsurgical anatomy of this segment of the VA has been explored in various populations, and a thorough understanding of the anatomy and course of the VA, particularly the V3 segment, is essential to prevent iatrogenic complications. Several computed tomography studies but a few cadaveric studies have explored the V3 segment of the VA in the South Indian population.
METHODS: This study examined 40 VAs from 20 embalmed cadavers that were obtained from the voluntary donation program, and Institutional Ethical Clearance was obtained before the study. The length, diameter, and angle of the vertical, horizontal, and exit parts of the V3 segment of the VA were documented after its exposure.
RESULTS: The mean lengths of the right and left VAs on each part were nearly similar, except for the mean length of the horizontal part (right: 38.937 mm, left: 40.237 mm) and total length of the V3 segment (right: 66.870 mm, left: 70.350 mm).
CONCLUSIONS: These morphometric parameters are essential to spine surgeons who intend to operate on a small part (vertical, horizontal, or exit part) of the V3 segment of the VA. The mean values of the parameters obtained in this study give average measurements or safe limits to surgeons for safe surgical procedures such as the occipital condyle screw technique and C1 laminectomy.

摘要：
■描述性的，椎动脉（VA）大西洋部分（V3）的定量横断面研究。
■这项研究旨在弥合南印度人口中VAV3段形态计量学的研究空白。
■已经在各种人群中探索了VA的这一部分的显微外科解剖结构，彻底了解VA的解剖结构和过程，特别是V3段，对预防医源性并发症至关重要。一些计算机断层扫描研究，但一些尸体研究已经探索了南印度人口中VA的V3段。
■这项研究检查了从自愿捐赠计划中获得的20个防腐尸体的40个VAs，在研究之前获得了机构伦理许可。长度,直径,和垂直的角度，水平,在暴露后记录了VAV3段的出口部分。
■每个部分的右侧和左侧VA的平均长度几乎相似，除了水平部分的平均长度（右：38.937毫米，左：40.237毫米）和V3段的总长度（右：66.870毫米，左：70.350毫米）。
■这些形态参数对于打算在一小部分（垂直，水平,或退出部分）VA的V3段。在这项研究中获得的参数的平均值为外科医生提供了平均测量值或安全限制，以进行安全的外科手术，例如枕骨髁螺钉技术和C1椎板切除术。
