Mapping, classification, and surgical strategy for vertebral artery variation in posterior atlantoaxial joint release, distraction, and fusion surgery for basilar invagination and atlantoaxial instability
The authors introduced a novel method of describing the VA course at the CVJ, called VA mapping, and a VA classification system was proposed to enhance the understanding of risk evaluation in the context of atlantoaxial joint release, distraction, and fusion. A risk stratification system was determined based on bilateral VA patterns, and specific surgical strategies were formulated. The overall iatrogenic VA injury rate was 1.6%, indicating the proposed classification and surgical protocol are reliable and reproducible for minimizing the risk of intraoperative VA injury.
