ABSTRACT
AbstractOBJECTIVE: To study modalities and complications of intrauterine exchange transfusion (IUET) for the management of severe fetal anaemia.STUDY DESIGN: Retrospective study of all IUET procedures performed between January 1999 and January 2012 at a regional centre. Characteristics of each procedure were studied to identify risk factors for complications. Survival rates according to the different aetiologies of anaemia were evaluated.RESULTS: In total, 225 IUET procedures were performed in 96 fetuses. Major indications were feto-maternal erythrocyte alloimmunization (n=80/96, 83.3%) and parvovirus B19 infection (n=13/96, 13.5%). Twenty-six percent of the fetuses (25/96) had hydrops fetalis before the first IUET. Intrauterine fetal death occurred after 2.7% (6/225) of procedures, premature rupture of the membranes occurred after 0.9% (2/225) of procedures, and emergency caesarean section was required after 3.6% (8/225) of procedures. Fetal bradycardia [odds ratio (OR) 37, 95% confidence interval (CI) 8.3-170; p<0.01] and gestational age up to 32 weeks (OR 3.67; 95% CI, 1.07-12.58; p=0.038] were significantly associated with complications after IUET. Complications occurred in 17.7% of pregnancies (17/96) and 7.5% of IUET procedures (17/225). The overall survival rate in the study cohort was 87.5% (84/96): 90% (72/80) in the alloimmunization group and 76.9% (10/13) in the parvovirus-infected group (NS).CONCLUSION: IUET has a higher complication rate than simple intrauterine transfusion, and should be performed by well-trained specialists.Copyright © 2014.
