Vertical distance between umbilicus to aortic bifurcation on coronal view in Korean women

Abstract

ObjectiveTo evaluate the vertical distance between umbilicus to aortic bifurcation on coronal view in Korean women and their relation with body mass index (BMI) and woman's age.MethodsThis retrospective study included 257 women who visited emergency center at university-based hospital from January to December 2011. All women underwent abdomino-pelvic computerized tomography (CT) due to various symptoms in a supine position. By using the electronic coronal CT images, the vertical distance between umbilicus and aortic bifurcation was measured. If aortic bifurcation was located below umbilicus, the distance was expressed as minus value (i.e., caudal to umbilicus). Age of woman, body weight, height and calculated BMI (kg/m2) were also recorded.ResultsAortic bifurcation was located caudal to umbilicus in 52.9% and cephalad to umbilicus in 37.4%. The vertical distance had a negative relationship with BMI (r=.0.180, P=0.004), as well as woman's age (r=-0.382, P<0.001). However, a multivariate analysis revealed that the vertical distance had a significant negative relationship with woman's age (P<0.001) but not with BMI (P=0.510). An equation could be drawn to estimate the vertical distance by using woman's age and BMI: vertical distance (mm)=12.6-0.3×(age)-0.2×(BMI).ConclusionThe vertical distance from umbilicus to aortic bifurcation on coronal view showed a significant inverse correlation with woman's age, however, the distances varied widely. Most older or obese Korean women had aortic bifurcation caudal to umbilicus.

Supraumbilical primary trocar insertion for laparoscopic access: the relationship between points of entry and retroperitoneal vital vasculature by imaging

“…Jeong et al 13 reported in 2014 that the vertical distance between the umbilicus and the aortic bifurcation in 257 Korean women who were 8-93 years old was correlated negatively with advancing age, so that the distance from the skin to vasculature decreased as a woman's age increased. Unfortunately, the abdominal wall thickness was not measured in that study…”

“…A series of studies have con rmed that the umbilicus is a reliable surface landmark for the AB (25)(26)(27)(28)(29), though the study populations were predominantly female (25)(26)(27)29). The current study found that the vertical distance of the umbilicus-AB in women or skinny patients was smaller than that in men or obese people.…”

“…In other words, younger patients may be at higher risk for both great vessel injury and for pre-peritoneal insufflation. In a retrospective study of 257 Korean women, it was found that the vertical distance from umbilicus to aortic bifurcation on coronal view showed a significant inverse correlation with woman’s age; however, the distances varied widely [10]. The difference in findings could be explained by 2 important points.…”

“…First, they measured the distance between the umbilicus and aortic bifurcation, while we measured the perpendicular distance from the umbilicus to the corresponding part of the aorta regardless of the bifurcation site. Second, Jeong et al [10] did not measure the anterior abdominal wall thickness in their study; consequently, their observed relationship could be confounded by the age-associated change in abdominal wall thickness, intraperitoneal distance, or both.…”
