[Sickle cell anemia and pregnancy. Complications and management].

An increasing number of sickle cell disease patients are deciding to bear children. The high risk of fetal and maternal complications in pregnant sickle cell disease patients mandates multidisciplinary management. Risks include spontaneous abortion, vasculorenal syndrome, fetal growth retardation, and fetal death in utero. The rates of cesarean section, maternofetal infection, and maternal death are higher than in the population at large. The diagnosis should be made prior to conception or during early pregnancy. Frequent visits with the obstetrician, hematologist, and anesthesiologist/intensivist are mandatory. Exchange transfusion or blood transfusion may be indicated in patients with a history of serious obstetrical or hematologic complications. Risks are highest in late pregnancy, during delivery, and in the postpartal period. However, the entire pregnancy is a high-risk period that warrants close monitoring.
