THE ARGUMENT FOR RIGHT OVER LEFT CANNULATION OF INTERNAL JUGULAR VEIN — AN ANATOMICAL STUDY
Keywords:
Internal jugular vein, diameter, central venous catheterization, cannulationAbstract
Objective: To record the diameter of internal jugular veins on each side in adults.
Material and Methods: This study was conducted in the department of Human Anatomy, Faculty of Medicine, Umm al
Qura University, Makkah, Kingdom of Saudi Arabia from April 2014 to December 2014. Twenty-eight (16 male and 12
female) cadavers were dissected on both sides and average measurements of the diameter of Internal Jugular Veins
(IJVs) were taken using calipers. The data was organized and statistically analyzed.
Results: Maximum diameter observed was in the male and on the right side (2.16 cm) while minimum diameter (0.66
cm) was seen in the female on the left side. Mean diameters were: 1.91±0.37 cm and 1.43 ± 0.81 cm in the male and
0.84 +0.17 and 0.63 + 0.12 in the female on the right and left sides respectively. Comparisons between the two sides
and genders were statistically significant at p < 0.05. Larger diameter on the right side was more prevalent both in the
male (81.25%) and in the female (66.6 %). Equal diameter on both sides was not seen.
Conclusion: Right internal jugular vein due to its larger diameter is more suitable for catheterization and cannulation
in both genders.
