Temporary, transvaginal occlusion of the uterine arteries: a feasibility and safety study.

A Doppler-guided, transvaginally applied paracervical clamp safely and effectively occluded the uterine arteries in 10 women. Following closure of the clamp, blood flow through the uterine arteries stopped; flow returned immediately upon clamp release. Average time of clamp closure was 26 minutes (range 10-59 min).
