[Pregnancy and portal hypertension due to a pre-hepatic block. 3 case histories (author's transl)].

The authors studied the prognosis for the pregnancies in cases of portal hypertension due to pre-hepatic block in 3 patients who between them had 6 pregnancies without having had previous porto-caval anastomoses. In spite of the good results that they had in their cases the literature shows that the condition is a high-risk pregnancy condition: 44 p. 100 of cases have intestinal tract haemorrhages, 19 p. 100 have premature labour and the perinatal mortality is somewhere between 11 and 18 p. 100. The babies are usually delivered vaginally with the aid of an assisted delivery.
