[Portal hypertension and pregnancy]

Abstract

Pregnancy in patients with portal hypertension is rare but worrying for the clinician. Although the effects of portal hypertension during pregnancy have not been fully elucidated, there is an evident increase in morbidity, especially associated with cirrhosis, which justifies the idea of at-risk pregnancy and requires management by a multidisciplinary team. The prevention and treatment of gastrointestinal haemorrhage is quite similar to that in nonpregnant patients. Investigation and management of portal hypertension before and at the beginning of pregnancy can reduce the risks of foetal loss, restricted intra-uterine growth, premature birth and maternal mortality, which are closely related to gastrointestinal haemorrhage. The risks related to the underlying disease, such as liver failure with cirrhosis and thromboembolic risk with vascular diseases associated with thrombophilia must be taken into consideration. Generally, vaginal delivery with early analgesics for the mother assisted by an extraction device should be preferred to caesarean section, which must be reserved for obstetrical indications.
