Anatomic variations of internal jugular vein inferior petrosal sinus and its confluence pattern: Implications in inferior petrosal sinus catheterization

摘要

ObjectiveThe purpose of this study is to describe anatomic variations of the internal jugular vein (IJV), inferior petrosal sinus (IPS) and their confluence pattern and implications in IPS catheterization. The anatomic route of IPS after going out of the cranium and its confluence patterns with IJV and will supply knowledge about typing of IPS-IJV junction.
