Highlights
- -We evaluated the distance between the right common iliac artery and lumbar vertebra
- -Distances were greater in men
- -There was a statistically significant relationship with age
- -Linear regression model showed a strong correlation between LVBIAD and LCIVD
Abstract
Objective
The current study aimed to evaluate the distance between the right common iliac artery
(RCIA) and lumbar vertebra in asymptomatic patients in order to determine whether
such distance was statistically correlated with the left common iliac vein (LCIV)
diameter (LCIVD) and to investigate if both measures were related to demographic characteristics
and anthropometric data, such as sex, age, height, and body mass index (BMI).
Methods
In this descriptive and uncontrolled anatomic study, data from high-definition computed
tomography (CT) angiography images of living kidney donors without a medical history
of chronic venous insufficiency or past deep vein thrombosis (DVT) were analyzed.
The RCIA crossed over the LCIV in 311 individuals, who were then included in this
study. CT scans were reviewed to measure (1) the narrowest space between the RCIA
and fifth lumbar vertebral body and (2) the LCIVD. Measures were subjected to normality
tests and were divided according to the sex of the study population. Correlations
of measures with age, BMI, and height were calculated.
Results
Of the 311 patients analyzed, 66.6% (n = 207) were female. The mean lumbar vertebral body–iliac artery distance (LVBIAD)
was 7.2 mm, whereas the mean LCIVD was 8.5 mm; both were higher in men (P < .001). The statistical analysis of LVBIAD and LCIVD distributions revealed no normality
pattern (P < .05). The analysis of the correlation between them showed a weak statistically
significant relationship with age. A linear regression model considering the normality
percentile interval indicated a strong positive correlation between LVBIAD and LCIVD
(R2 = .884).
Conclusions
The LVBIAD was <5 mm and <3 mm in 25% and 5% of asymptomatic individuals, respectively.
The LCIVD correlated with the space between the RCIA and lumbar vertebra. The distance
between the RCIA and lumbar vertebra and the LCIVD were higher in male subjects and
older patients, but did not correlate with BMI and height.
