Key result
Simulated 30-degree body rotation significantly increased the incidence of overlap between the internal jugular vein and the common carotid artery from 42.0% to 91.4% (P = 0.000).

Head or body rotation during internal jugular vein catheterization significantly increases overlap with the common carotid artery, highlighting the increased risk of inadvertent arterial puncture without ultrasound guidance.
Background: It is important to understand the anatomical relationship of the internal jugular vein (IJV) to the common carotid arteries (CCAs) to avoid inadvertent arterial injury. This study used computed tomography (CT) to evaluate this relationship and the changes associated with simulated 30 o body rotation (SR30) in Korean subjects. Methods: A retrospective analysis of 81 healthy adult subjects was performed using CT during physical checkups between November 2012 and September 2013. Data on both the left and right side IJV and CCA were recorded at the level of the cricoid cartilage and analyzed. The CCA was used as a reference for estimating the IJV location; this was recorded as lateral, anterior, medial, or posterior, using a segmented grid. The degree of overlap was calculated as a percentage, and changes to the anatomic relationship and overlap percentage caused by SR30 were derived.

So et al. (2015) conducted a cross-sectional in Healthy adults (n=81). Simulated 30-degree body rotation (SR30) vs. Supine position with neutral head position was evaluated on Incidence of overlap between the internal jugular vein and common carotid artery (p=0.000). Simulated 30-degree body rotation significantly increased the incidence of overlap between the internal jugular vein and the common carotid artery from 42.0% to 91.4% (P = 0.000).
