Özet:

    Conclusion: According to the results of this study, the right-side IJV diameter was found to be statistically significantly greater than that of the left side  in Turkish population. Valsalva effects, age and gender are non-effective on diameters. Distinguishing the diameters , surgical and interventional risks can be decreased. Results: No statistically significant difference was determined in respect of diameter values above and below 60 years of age(p<0.05). No statistically significant difference was determined between male and female genders in respect of all the diameter values  (p<0.05) except LIJV in transverse diameter with valsalva .The right IJV diameter in both the transverse and anteroposterior sections were determined to be statistically significantly wider  both at rest and during the Valsalva maneuver (p<0.05). Patients-Methods: The study included a total of 140 patients. The maximal transverse and anterior-posterior diameters of the internal jugular veins were measured on both sides, both with the patient at rest and during the Valsalva maneuver with USG. Objective: As the internal jugular vein (IJV) is a vessel used for cannulation in central venous approaches in medical applications, knowledge of the anatomic details is significant for  clinicians knowing that vascular diameter varies according to age and gender is an extremely useful data. The aim of this study was to evaluate  differences in the right and left  side diameters of the internal jugular vein in  normal adult Turkish population and to determine any relationship between these diameters and age, gender and maneuver.
