ABSTRACT
Background and purpose: Knowledge of the normal diameters of the IVC is important regarding the detection of the abnormality and valuable in the treatment of patients suffering from traumatic shock. There is sparse literature about the evaluation of normal inferior venacava diameter. We aimed to derive a range of measurement in inferior venacava diameter.
Materials and methods: This prospective cross-sectional study was undertaken to evaluate the diameters of the IVC as well as their association to gender and age. The study was performed 163 patients (77 males and 86 females) with a mean age of 51.09 years, free of cardiac and renal congenital disease, who were referred for abdominal CT to Department of Radiology and Imaging of Tribhuvan University Teaching Hospital, Kathmandu from January 2021 to May 2021.Anteroposterior (AP) and transverse (T) diameters of the IVC were measured just above the renal vein.
Results: This study revealed that the mean± standard deviation (SD) of the anteroposterior (AP) diameter of the IVC in men measured was 14.81±2.03 mm, 15.84±2.22 mm in women. The mean± standard deviation (SD) of the transverse (T) diameters, measured were 26.02±2.77mm in women and 26.60±2.63mm in men.
Conclusion: The information provided in this study will allow clinician to detect and accurately characterize IVC abnormalities which will guide in clinical decision making and improving patient care. Future studies should focus on large scale multicenter enrollment.
