Summary: Over a 10‐year period when 51,022 singleton infants were delivered, 19 pregnancies (1 in 2,685) were complicated by acute polyhydramnios, 17 (1 in 3,000) by subacute polyhydramnios and 501 (1 in 102) by chronic polyhydramnios. The incidence of major congenital malformations in singleton pregnancies associated with acute polyhydramnios was 63% and the perinatal mortality rate was 74%. When subacute polyhydramnios occurred in singleton pregnancies, the incidence of major congenital malformations was 65%, similar to acute polyhydramnios, but the perinatal mortality rate was only 35%. The comparable figures for chronic polyhydramnios in singleton pregnancies were a major malformation incidence of 14% and perinatal mortality rate of 10%. The type of onset of polyhydramnios, acute, subacute or chronic is therefore the most important indicator of prognosis. In patients with gross polyhydramnios, acute renal failure must be specifically excluded.
