The study evaluated the anatomy and variability of the ovarian blood supply in 243 cesarean pregnancies undergoing uterine artery embolization using digital subtraction angiography. The left ovarian artery was visualized in 42.8% of patients and the right in 44.86%, bilaterally in 18.52%, while none was visible in 20.58%. Ovarian branches of the uterine artery were manifested in 39.51% on the left side (n=96) and in 38.27% on the right (n=93), while the staining of the ovarian parenchyma was in 70.83% (n=68) of the left and in 67.74% (n=63) of the right. There were no statistically significant differences between the sides (P > 0.05). Complete visualization of all four vascular sources was in 8.23% of cases and complete absence in 13.58%. Ovarian blood supply shows great individual variability, with the ovarian branches of the uterine artery contributing significantly to perfusion. A comprehensive examination of both sides of the DSA is essential to minimize the risk of ovarian dysfunction during embolization.
