Ligation of uterine vessels reduces arterial blood flow of uterine arcades.

Doppler blood velocity waveforms were obtained from an artery of the uterine arcade before (A) or after (B) ligation of ovarian vessels. (C) Summary of arterial blood flow velocity of 4 uterine arcades (4 peaks each) before and after ligation of ovarian vessels. Doppler blood velocity waveforms were obtained from an artery of the uterine arcade before (D) or after (E) ligation of uterine vessels. (F) Summary of arterial blood flow velocity of 5 uterine arcades (4 peaks each) before and after ligation of uterine vessels. (G) Percentage of velocity change relative to velocity before ligation. n = 4 (ovarian vessels) and n = 5 (uterine vessels).
