O Doppler da artéria oftálmica é um método objetivo que pode facilitar o diagnóstico da hipertensão durante a gestação, identificando suas diferentes manifestações. Diferenciar, por meio do Doppler da artéria oftálmica, as gestantes portadoras de pré-eclâmpsia daquelas portadoras de hipertensão arterial crônica. Estudo transversal de 30 gestantes com hipertensão arterial crônica e 31 gestantes com pré-eclâmpsia (National High Blood Pressure Education Program, 2000) realizado no terceiro trimestre de gestação. Todas as gestantes realizaram proteinúria de 24 horas e Doppler da artéria oftálmica direita. A dopplervelocimetria da artéria oftálmica avaliou os seguintes parâmetros, para quantificação da onda de velocidade de fluxo: índice de resistência (IR), índice de pulsatilidade (IP), pico de velocidade sistólica (PVS), pico de velocidade diastólica (PVD), velocidade diastólica final (VDF) e razão entre picos de velocidade (RPV). Os resultados foram submetidos à análise estatística, considerando-se significativos quando p<0,05. As médias dos índices Doppler das gestantes com pré-eclâmpsia e hipertensão arterial crônica foram respectivamente: IR= 0,649 + 0,067; 0,718 + 0,077, IP= 1,205 + 0,326; 1,555 + 0,373, PVS: 34,280 + 9,306; 35,206 + 9,941, PVD: 26,513 + 10,060; 19,752 + 5,847, VDF: 11,951 + 4,060; 9,696 + 3,223 e RPV: 0,77 + 0,16; 0,57 + 0,11. Os índices de resistência e de pulsatilidade da artéria oftálmica das gestantes com pré-eclâmpsia foram significativamente inferiores aos das gestantes hipertensas crônicas. Observou-se tendência de aumento dos valores do pico de velocidade diastólica e da velocidade diastólica final de gestantes com pré-eclâmpsia, quando comparadas... / The differential diagnosis of pregnancy hypertensive syndromes is based on clinical, laboratorial as well as fundoscopy findings. The ophthalmic artery Doppler is an objective method which may facilitate the diagnosis of hypertension during pregnancy, distinguishing its several manifestations. Differentiate, through ophthalmic artery Doppler, women with preeclampsia from those with chronic arterial hypertension. Cross-sectional study which analyzed 30 pregnant women with chronic arterial hypertension and 31 with preeclampsia (National High Blood Pressure Education Program 2000) during the third trimester of pregnancy. 24-hour urine was checked for proteinuria in all patients and the ophthalmic artery Doppler examination was taken by them. The Doppler velocimetry of the ophthalmic artery has evaluated the following parameters for quantification of flow velocity waveforms: resistance index (RI), pulsatility index (PI), peak systolic velocity (PSV), peak diastolic velocity (PDV), end diastolic velocity (EDV) and ratio between the velocity peaks (PR). Median and standard deviation were applied to the data. The average of the Doppler indexes on pregnant women with preeclampsia and chronic hypertension was respectively: RI= 0,649 + 0,067; 0,718 + 0,077, PI= 1,205 + 0,326; 1,555 + 0,373, PSV: 34,280 + 9,306; 35,206 + 9,941, PDV: 26,513 + 10,060; 19,752 + 5,847, EDV: 11,951 + 4,060; 9,696 + 3,223 e PR: 0,77 + 0,16; 0,57 + 0,11. The resistance and pulsatility indexes of the ophthalmic artery Doppler on women with preeclampsia were significantly inferior to those with chronic hypertension. It was observed that there is a tendency of increasing the values of the peak of diastolic velocity in addition to the end diastolic velocity on women with preeclampsia when compared to those with chronic hypertension. The ratio of the peak of velocity was significantly superior on pregnant women... (Complete abstract click electronic access below)
