title: [Value of the velocimetry study of the uterine arteries in retro-placental hematoma. Report of 3 cases].
abstract: Retroplacental hematoma is a sudden accident with unfavorable prognosis, especially since predictive signs (clinical, biological or ultrasonographic) are very frequently absent. The purpose of this study was to determine whether velocimetric study of the uterine arteries is of predictive value in this pathology. The equipment used was Doppler ultrasound with spectral analysis (4-MHz probe) without echography. Each examination consisted in systematic study of both uterine arteries and of umbilical flow. The recording technique for the uterine arteries is described, and 3 cases of retroplacental hematoma are reported. In all 3 cases, the resistance index for one of the uterine arteries (right twice, left once) was high, with the presence of a (proto-diastolic notch on the curve, whereas the umbilical index was normal and there were no other signs predictive of the placental accident. The value of Doppler exploration has already been demonstrated for numerous obstetric indications, and it should be possible to include others, particularly if this preliminary study is confirmed on a larger scale.
