Anatomical variants of the uterine artery: 214 angiotomographies

Abstract

The aim of the work is to know the changes that the uterine artery undergoes with age, the determination of its origin and its possible variants. Cross-sectional, comparative, descriptive, retrospective study Angiotomographies of the abdomen and pelvis of female patients were obtained, reformatted in 3D, analyzing the uterine arteries (thickness, origin and trajectory). Measurements were carried out by two medical specialists in diagnostic imaging. 107 CT angiograms of patients with a mean age of 56.62±16.97 years (range 1890) were included. The average thickness of the uterine arteries was 2.16 mm (±0.38 mm). Divided by laterality and age groups, they were 2.35 mm, 2.19 mm and 2.36 mm on the right side and 2.19 mm, 2.07 mm and 2.15 mm on the left side, respectively. There was no statistically significant difference in thickness between the three groups (p=0.08). Five types of anatomical variants are described with prevalence of 85.1% in type I, 6.75% in type II, 5.4% in type III, 2.02% in type IV and 0.67% in type V, the latter coming directly from the left ovarian artery. There are five diffe– rent anatomical variants in our population, Type I is the most predominant. There are no significant morphological changes with age, except for an increase in vascular lesions, mainly atherosclerosis, in people over 50 years of age.
