CTA-based classification of occipital artery course variations at the atlanto-occipital interval, with surgical implications

Key Points

To classify variations in the occipital artery course using CTA for better surgical planning.
Used CTA to assess occipital artery topography at the atlanto-occipital interval.
Developed a structured classification framework for preoperative assessment.
Analyzed course variations and their surgical relevance.
Identified key variations in occipital artery positioning.
Demonstrated the link between intrasulcal course and surgical approaches.
Provided insights useful for bypass procedure planning.

Abstract

This CTA-based classification provides a structured framework for preoperative assessment of OA topography. The association between intrasulcal course and supraatlantal positioning may inform surgical planning for far-lateral exposures and OA harvest for bypass procedures.
