Introduction: Massive perivillous fibrin deposition (MPVFD) in the placenta is associated with pregnancy complications and maternal disease. The aim of the current study was to contribute with increased knowledge regarding MPVFD by comparing maternal characteristics, obstetric and perinatal outcome and recurrence rate according to the degree of MPVFD. Material and methods: This retrospective observational study included 141 cases of MPVFD collected between January 2003 to December 2018 in the Stockholm region, Sweden. The extent of fibrin deposition was assessed as low (20-32%), moderate (33-50%) or severe (>50%) according to macroscopic examination. Results: The study covered 48 placentas with low MPVFD, 41 with moderate and 52 with severe MPVFD. Severe MPVFD was associated with more prematurity than moderate and low MPVFDs (56.3% vs 34.2% and 34.0% respectively, p = 0.05 and p = 0.04). In cases with severe MPVFD, 72.3% of the liveborn infants were growth restricted compared to 34.2% in the moderate group (p = 0.001) and 52.2% in the low group (p = 0.06). The incidence of intrauterine fetal death was 31.3% in the severe MPVFD group, which was significantly higher than in the low MPVFD group (8.5%, p = 0.01) and twice as much as in cases with moderate MPVFD (15.8%, p = 0.07). 105 subsequent pregnancies after an index pregnancy with MPVFD were identified. The outcome was favourable with a liveborn rate of 91-100%. Discussion: The extent of fibrin in the placenta plays a role in pregnancy outcome. Cases with severe MPVFD in the placenta was associated with more prematurity, fetal growth restriction and intrauterine fetal death.
