title: [Notching of the bilateral uterine artery flow velocity wave-forms in the third trimester and perinatal complications].
abstract: Pulsatile color duplex Doppler ultrasonography system was used to study blood flow velocity waveforms in the uterine arteries of 492 pregnant women in the third trimester. In 38 (7.7%) patients unilateral and in 42 (8.5%) bilateral postsystolic notches were observed. Those with bilateral early diastolic notches experienced poor perinatal outcome in 40 (95.2%) instances. The same occurred in 16 (42.1%) others with unilateral notches and in 13 (3.2%) without notches but with evidence of increased impedance (pulsatility index > 1.20, resistance index > 0.58 and systolic/diastolic ratio > 2.6). The presence of bilateral postsystolic notches in the uterine artery flow velocity waveforms appears to be a reliable predictor of poor pregnancy outcome.
