Rhesus isoimmunization.

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Disease severity may be assessed using the modalities described above and frequently, invasive techniques are required to determine the risk of severe disease. Doppler flow studies appear to offer accurate, noninvasive means of evaluating fetal risk, which may allow for a decrease in invasive diagnostic procedures. The Rh isoimmunized patient, managed by an experienced team, can anticipate a favorable pregnancy outcome.
