Umbilical flowmetry in twin pregnancy. A method for identifying discordant feta...
Clode, N; Serviço de Obstetricia e Ginecologia, Hospital de Santa Maria, Faculdade de Medicina de Lisboa.; Casal, E; Graça, L MUmbilical 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 n...
Hypertension associated with pregnancy. Epidemiologic study of 311 consecutive ...
Machado, M H; Serviço de Obstetrícia e Ginecologia, Hospital de Santa Maria/ Faculdade de Medicina de Lisboa.; Clode, N; Graça, L M; Cardoso, C GThe epidemiologic aspects of 311 consecutive cases of hypertension associated with pregnancy seen in the Department of Obstetrics and Gynecology, Hospital de Santa Maria/University of Lisbon Medical School between January 1st 1988 and December 31st 1992, are reviewed. Seventeen cases were multifetal pregnancies. Using the criteria proposed by the American College of Obstetricians and Gynecologists the cases wer...
The clinical implications of the characteristics of uteroplacental flow in preg...
Clode, N; Departamento de Obstetrícia e Ginecologia, Hospital de Santa Maria, Faculdade de Medicinia de Lisboa.; Nunes, J; Cardoso, C; Graça, L MThe study of the relationship between maternal and perinatal outcome with uterine blood flows using a continuous wave Doppler unit, in hypertensive patients was the aim of our work. One hundred and thirty seven pregnant hypertensive women seen and delivered at the Department of Obstetrics, Santa Maria Hospital, Lisbon, were included in the study. Blood flows were classified as abnormal if and when the systolic/...
The HELLP syndrome in pregnancy-related hypertension.
Machado, M H; Serviço de Obstetrícia e Ginecologia, Hospital de Santa Maria, Faculdade de Medicina de Lisboa.; Graça, L M; Clode, NDuring a 5-year period, 13 cases of HELLP syndrome were seen in hypertensive patients in the Obstetrics Department, Santa Maria Hospital, Lisbon. In 7 cases the syndrome occurred antepartum and in 6 during early early puerperium; gestational age and clinical features were very different from case to case. Four cases of eclampsia and 2 cases of acute renal failure occurred in 5 patients; there were 2 intrauterin...
Relationship between the Steuart resistance index of the umbilical artery in no...
Clode, N; Serviço de Obstetrícia e Ginecologia, Hospital de Santa Maria, Faculdade de Medicina de Lisboa.; Marques, J P; Casal, E; Graça, LUmbilical 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 tw...
Doppler flowmetry of feto-maternal circulation: III --Absent and reverse diasto...
Graça, L M; Unidade de Alto Risco Obstétrico, Hospital de Santa Maria/Faculdade de Medicina, Lisboa.; Clode, N; Cardoso, C G; Colaço, A; Casal, ETwelve 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 so...
