Doppler da Artéria Cerebral Média e Risco de Anemia Fetal
Calculadora de Risco de Anemia Fetal por meio da Dopplervelocimetria da Artéria Cerebral Média.
|
A artéria cerebral média (ACM) deve ser examinada próxima a sua origem na artéria carótida interna. O ângulo do feixe sonoro deve ser próximo a zero (jamais acima de 30 graus). O risco de anemia fetal grave é maior em fetos com velocidade de pico sistólico superior a 1,5 múltiplos da mediana.
