“…2,4 The likelihood of adverse perinatal outcome is reduced in well-controlled diabetic pregnancies. [5][6][7] Perinatal care of pregnant women with diabetes mellitus lies in correct metabolic management, stringent surveillance, and monitoring of serum glucose levels. One of the instruments of modern perinatal surveillance is Doppler velocimetry, which may estimate vascular impedance in placental circulation.…”

Background-The aim of the study was to evaluate the relation between maternal placental Doppler velocimetry, levels of the maternal glucose, and clinical signs of vasculopathy in pregnancy complicated by pregestational diabetes mellitus. Methods and Results-A retrospective study of 155 pregestational diabetic women between the 22nd and 40th weeks of pregnancy, categorized in White classification as B, 49; C, 40; D, 22; R,20; F,5; and RIF,19. Cases in classes R, F, and R/F were defined as having vasculopathy. Doppler velocimetry of umbilical and uterine arteries was evaluated for vascular impedance, both in terms of pulsatility index (PI) for both arteries and a notch in early diastole in the uterine arteries. The last examination before delivery was used for analysis. Increased umbilical artery PI was seen in 19 and a uterine artery abnormality in 45 cases. There was a correlation between levels of HbA lc and increased vascular impedance in the uterine and umbilical arteries. Signs of increased uterine artery vascular impedances were significantly related to pregestational vasculopathy. In cases of small-for-gestational-age newborn infants, PI was significantly increased in uterine and umbilical arteries. Furthermore, PI in macrosomic fetuses was significantly lower than in normal infants. Abnormal uterine artery Doppler was also strongly related to adverse outcome. Conclusions-Abnormal

“…A avaliação da dopplervelocimetria da arté-ria umbilical em gestantes diabéticas não têm demonstrado associação da doença com anormalidades da circulação placentária ou fetal 9,21 . Porém, quando ocorre associação com outras anormalidades tais como a hipertensão ou a vasculopatia, esta técnica tem papel fundamental na avaliação da função placentária 22,23 .…”

“…A dopplervelocimetria da artéria cerebral média também não apresentou alterações significativas nesta casuística. Do mesmo modo, Salvesen et al 9 não puderam demonstrar alterações no fluxo da aorta fetal e da artéria cerebral média, a despeito do aumento dos níveis de hematócrito constatado no sangue fetal colhido por cordocentese. Os autores sugerem que seriam necessárias graves alterações na viscosidade sangüínea para que fossem detectadas anormalidades.…”

RESUMO Objetivos: estabelecer parâmetros dos testes de vitalidade fetal em gestações com diabete melito pré-gestacional que se correlacionam com a ocorrência de recém-nascidos (RN) grandes para idade gestacional (GIG RN GIG, nas semanas: 32ª (16,5 cm, p=0,02), 33ª (16,7 cm, p=0,03), 34ª (17,0 cm, p=0,02), 35ª (17,9 cm, p=0,000), 36ª (15,8 cm, p=0,03) e 37ª (17,5 cm, p=0,003 RN GIG, nas semanas: 34ª (60%, p=0,03), 35ª (71,4%, p=0,01), 36ª (80%, p=0,02) e 37ª (66,7%, p=0,04

“…It was found that the mean umbilical venous blood pH was significantly lower and the haematocrit significantly higher than the appropriate normal mean for gestation for these diabetic pregnancies. However, the Doppler indices of the placental and fetal circulations were essentially normal, except in some of the cases complicated by pre-eclampsia or intrauterine growth restriction (Salvesen et al, 1993). It was thus concluded that maternal diabetes mellitus was not associated with abnormalities in Doppler indices of the placental or fetal circulations.…”
