This study analyzed the subjects of 64 pregnant women of cesarean section performed for the period of amenorrhea 28 weeks and amenorrhea 42 weeks, at Hallym university Kang Nam Sacred Heart Hospital from May, 1988 through December, 1990. The 64 patients were studied who manifested 33 pregnancy induced hypertension and 31 normal term pregnancies. The uterine arcuate artery and umbilical artery blood flow velocity wave form examination were obtained all patients before cesarean section and placental bed biopsies obtained in all patients at cesarean section. The result of this study were as follows; 1. The association of physiological change of the spiral artery with uncomplicated pregnancy and their absence of pregnancy induced hypertension has been confirmed. 2. The physiological change of spiral artery of normal pregnancy shows low S/D ratio of fetal umbilical artery velocity (2.37±0.30) (Mean±S.D.), pathological invasion of spiral artery shows high S/D ratio of fetal umbilical artery (3.35±0.65)(Mean±S.D.) (P<0.01). 3. Physiological changes of spiral artery of normal pregnancy shows low R.I. of caternal uterine arcuate artery veolcity (0.46±0.08)(Mean±S.D.), pathological changes of spiral artery of pregnancy induced hypertension shows high R.I. of arcuate artery velocity (0.62±0.10)(Mean±S.D.)(P<0.001). These data indacate that abnormal doppler waveform in arcuate artery correlates pathologic invasion of spiral artery.
