Measurement of aorta sacral promontory distance in females on contrast enhanced CT abdomen and its correlation with Age and BMI

Abstract

Aims and objective: To measure the aorta-sacral promontory distance among the females referred for contrast enhanced CT abdomen. Material and methods: A quantitative, cross-sectional study was conducted in the Department of Radiology, Narayana Supespeciality Hospital, Howrah, West Bengal, India from May 2017 to June 2018. Total of 200 patients underwent Contrast Enhanced CT abdomen. The age, height and weight of the patients were noted and aorta sacral promontory distance was determined. Results: The mean age was found to be 51.37 years, mean APT distance 4.61 ± 0.80 cm and mean BMI 24.88. Increase in age was correlated with decrease in APT distance but there was no correlation between BMI and APT distance. According to this study, APT distance was decreased in elderly female patients but no significant change in BMI and APT. Conclusion: In this study using CT, we found that as the age increased, APT distance decreased and there was no significant change in relation to BMI. Therefore, during sacral colpopexy, the surgeon should be careful and consider the aorta sacral promontory distance in the elder female patients while performing dissection.
