Retrospective review reveals key anatomical differences in IJVs, indicating optimal catheter placement strategy.

The right internal jugular vein exhibits less anatomical variation and is generally preferred for vascular access.
Ninety percent of IJVs were positioned lateral to the common carotid artery, crucial for catheter placement.
The right IJV was found to have a significantly greater mean diameter and was more superficial than the left.
Utilizing anatomical insights can minimize complications associated with central venous catheter placement.

Teeratakulpisarn et al. (2025) studied this question.
