Maternal and fetal outcomes in pregnant patients with non-cirrhotic portal hypertension: A systematic review and meta-analysis.

BACKGROUND: Concerned studies with respect to the outcome of pregnant patients with non-cirrhotic portal hypertension are limited. Thus, a systematic review and meta-analysis of the available literature was conducted.

METHODS: A literature search was conducted from 1999 to December 2021 for studies evaluating pregnancy outcomes in patients with non-cirrhotic portal hypertension.

RESULTS: Twelve studies were included in the meta-analysis. The pooled rate of variceal bleeding, ascites and severe anemia requiring blood transfusion were 9.6%, 2.3%, and 14.9%, respectively. The pooled rate of spontaneous miscarriage, gestational hypertension, delivery by cesarean section, and postpartum hemorrhage were 11.9%, 4.5%, 36.7%, and 4.7%, respectively. The pooled stillbirth rate was 2.5% and among the live births, the pooled rates of preterm birth, low birth weight, intensive care unit admission, and neonatal mortality were 21.6%, 18.7%, 15.5%, and 1.8%, respectively.

CONCLUSION: Pregnancy in patients with non-cirrhotic portal hypertension is associated with increased maternal & fetal morbidity but mortality remains low.
