Recurrent Massive Perivillous Fibrin Deposition and Chronic Intervillositis Treated With Heparin and Intravenous Immunoglobulin: A Case Report.

BACKGROUND

Massive perivillous fibrin deposition (MPVFD) and chronic intervillositis (CI) are related rare pathological correlates of severe intrauterine growth restriction (IUGR) and fetal loss with high recurrence rates. No standard management has been established.

CASE: A patient underwent termination of pregnancy at 21 weeks for severe early onset IUGR. Placental histology showed mixed CI with MPVFD. Several months later, the patient became pregnant and was managed with prednisone and aspirin (ASA) but miscarried at 16 weeks. Placental pathology showed MPVFD and focal CI. For two subsequent pregnancies, she was treated with intravenous immunoglobulin (IVIG), heparin, and ASA. Both pregnancies resulted in healthy near-term deliveries with normal placentas.

CONCLUSION

IVIG, heparin, and ASA can be an option in patients with recurrent pregnancy loss due to MPVFD and CI.
