Absence of flow velocity waveform changes in uterine arteries after bilateral internal iliac artery ligation

A case is reported of bilateral internal iliac artery ligation during cesarean delivery for intractable hemorrhage. Uterine artery Doppler flow velocity waveforms were documented before and after the procedure. After the ligation the uterine arteries could still be visualized in the appropriate anatomic location, and no changes in Doppler flow velocity waveforms were documented.
