Massive perivillous fibrin deposition

Histological problem with the placenta leading to reduced foetal growth or miscarriage

Massive perivillous fibrin deposition refers to excessive deposition of fibrous tissue around the chorionic villi of the placenta. It causes reduced growth of the foetus, and leads to miscarriage in nearly 1 in 3 pregnancies affected. There are typically no symptoms, and it is rarely detected before birth. The cause is unknown, but may be autoimmune. Diagnosis is based on the histology of the placenta. There are currently no known treatments. MPFD is very rare, but recurrence is around 18% in those affected.
