Twin pregnancy in a patient on chronic haemodialysis who already had three pregnancies


Pregnancy in women with end-stage renal disease is rare. Multiple pregnancies carry a high risk of complications even in healthy individuals. We report the case of a 36-year-old woman who had four pregnancies while she was on dialysis, including one twin pregnancy. The last pregnancy occurred while in the 14th year of hemodialysis. At 8 weeks of gestation (WG), ultrasonography diagnosed a dichorionic diamniotic twin pregnancy. The frequency of dialysis was increased from 3 to 6 times a week and each session lasted 4 h. At 22 WG, polyhydramnios was diagnosed. At 25 WG, the patient presented respiratory distress and was transferred to intensive care where continuous hemodialysis, non-invasive ventilation, antibiotic and tocolysis were initiated. Because of tocolysis failure, a cesarean section was performed and she delivered male twins. The two newborns weighed 790 and 870 g, respectively. To our knowledge, this is the first report of four pregnancies in hemodialysis including one twin pregnancy. The incidence of pregnancy and a better outcome in patients on hemodialysis has increased in recent years but a tight coordination between nephrologists and obstetricians is essential.
