MOHAMED ABDELAZIZ, Martha et al. Value of uterine artery Doppler flowmetry for the prediction of some complications in pregnant women with chronic arterial hypertension. Rev Cubana Obstet Ginecol [online]. 2007, vol.33, n.2. ISSN 0138-600X.

Chronic arterial hypertension (CAH) during pregnancy is associated with an increased  risk of preeclampsia and intrauterine growth restriction (IUGR). In order to evaluate the value of  the uterine artery Doppler flowmetry at 24 weeks in the prediction of these complications, a prospective and descriptive study was conducted among 222 pregnant women with chronic arterial hypertension that received attention at Ramón Gonzalaez Coro Hospital, in Havana City. The association between the presence of diastolic notch at 24 weeks, the pulsatility index (PI), and the abnormal S/D ratio was studied The sensitivity, specificity, positive predictive value (PPV) and negative predicitive value (NPV) of the test for IUGR and preeclampsia were determined. The sensitivity of the diastolic notch  for the appearance of IURG was 78.6 % and the NPV was 98.4 %, whereas for eclampsia, the values were 64 % and 94.1 %, respectively. The abnormal PI had a sensitivity of 85.7 % and a NPV of 98.8 % for the predicition  of the appearance of IUGR. As to eclampsia, the values were 71.0 % and 95.0 %, respectively. Abnormal S/D ratio showed a sensitivity of 64.3 % and a NPV of 96.3 % in the prediction of IUGR. As regards  the appearance of preeclampsia, the values were 58.1 % and 90.4 %, respectively. The high NPV indicated the value of the uterine artery Doppler to predict the absence of adverse results in expectants with chronic arterial hypertension.
