[Umbilical flowmetry in twin pregnancy. A method for identifying discordant fetal growth?].

Umbilical artery velocimetry was performed in 33 twin gestations to evaluate the predictivity of the test (umbilical artery S/D difference between the pair > 0.4) in the screening of discordant fetal growth. Four out of 10 cases of discordant fetal growth were identified by the test and it was abnormal in 1 out of 23 concordant twins. The sensitivity was 40%, specificity 95%, positive predictive value 80% and negative predictive value of 79%. In spite of its low sensitivity the test can be useful in detecting discordant fetal growth in twin pregnancies.

[Relationship between the Steuart resistance index of the umbilical artery in non-pathologic pregnancy and the weight and ponderal index of the newborn].

Umbilical artery Doppler velocimetry was performed at 28-32 and 36-38 weeks of gestation in a low risk population to correlate the Stuart's resistance index (Sistole/Diastole--S/D) to the weight and ponderal index of the newborn, and to determine the preditive value of S/D ratio greater than the 95 centil in the screening of newborns of weight or ponderal index lower than the 10 centil. Two hundred and eight two pregnant women were studied (146 at 28-32 weeks; 221 at 36-38 weeks) and Stuart Resistance Index was obtained by a continuous wave Doppler System. In both periods we had an inversely proportional correlation between the resistance index and the weight and ponderal index of the newborn; nevertheless the low sensibility and preditive value of the test shows that it should not be used as an isolated diagnostic tool to screen a low risk population for newborns with a low weight or low ponderal index.

[Caustic esophagogastric lesions].

The authors treated is an emergency, severe esofagogastric lesions, in adults, by caustics ingestions. They present seven cases and discuss six deaths. Critical analysis of these observations compared with the findings of pathology and in the literature, permit one to consider the therapeutic indications. The early surgical treatment is suggested as the best way to obtain a more acceptable survival.

[Doppler flowmetry of feto-maternal circulation: III --Absent and reverse diastolic flow in the umbilical artery].

Twelve cases of extreme umbilical blood flow impairement (8 cases with loss of end-diastolic blood flow and 4 cases with reversed flow) found among 658 pregnancies studied by continuous Doppler between April 1st 1989 and March 31st 1990, are reported. The findings were associated to intra-uterine growth retardation (92%), maternal hypertensive disease (50%) and perinatal death (33%); fetal Trisomy 21 was the sole problem in one of the cases with absent end-diastolic frequencies. Our results are discussed and compared to similar data reported recently. Clinical management is proposed, according to umbilical blood flow patterns, length of gestation and underlying clinical situations.
