SANABRIA ARIAS, Ana Mary; NODARSE RODRIGUEZ, Alfredo  e  CARRILLO BERMUDEZ, Lourdes. Value of the middle brain artery Doppler flowmetry in the prediction  and follow-up of fetal anemia due to Rh isoimmunization. Rev Cubana Obstet Ginecol [online]. 2007, vol.33, n.2, pp. 0-0. ISSN 1561-3062.

Perinatal hemolytic disease due to Rh isoimmunization is still one of the most common causes of fetal anemia. Amniocentesis and chordocentesis have been used for many years for the diagnosis and follow-up of fetal anemia. These techniques are considered as invasive, and many complications are associated with their use. The noninvasive diagnosis of fetal anemia has been made through Doppler ultrasonography. Based on recent evidence, middle cerebral artery peak systolic velocity (MCA-PSV) could evaluate with great accuracy the degree of fetal anemia in Rh isoimmunization. This test also allows the diagnosis of fetal anemia due to other etiologies, prevents the application of unnecessary invasive procedures and, therefore, may reduce  perinatal morbidity and mortality.
