Comparison of Aorta-sacral Promontory Distance with Age and BMI in Female Patients Undergoing CT

Abstract

Introduction: Sacral colpopexy is the gold standard procedure for pelvic organ prolapse. During sacral colpopexy, various complications such as haemorrhage can occur. Careful dissection of presacral space is essential to minimize complications. Aim: The aim of the study was to compare patient age and Body Mass Index (BMI) with Computed Tomography (CT) measured aorta-sacral promontory distance. Materials and Methods: From 172 samples data such as age and BMI of female patients aged 18 years and above was collected. Study was performed on patients who underwent Contrast Enhanced Computed Tomography (CECT) scans of abdomen. The obtained data was statistically analyzed using Pearson’s correlation test and multiple linear regression. Results: The mean age was 56.5 years (range 18-95) and mean BMI was 23.25 (range 10.8-35.7). Increase in age is correlated with decrease in Aorta-sacral Promontory distance (APT) {Pearson’s correlation coefficient (r) is -0.795 between age and APT, p0.01). According to CT measurements aortopromontory distance is decreased in elderly female patients, but no significant changes in BMI and APT. Conclusion: The study showed that as age increases, APT decreases and there is no significant changes in relation to BMI. Therefore, during abdominal sacral colpopexy, the surgeon should be careful and consider the aortopromontory distance in the elder female patients while performing dissection.
