Abstract
A rare complication in twin pregnancy is acute polyhydramniosis. If left untreated, the perinatal mortality is 100%. the clinical courses of two cases treated with ultrasound-guided amniocentesis are presented. in the first case altogether 4 87S ml amniotic fluid was drained. Both twins died within the first 24 hours of life after delivery in gestational week 26. in the second case 2 150 ml amniotic fluid was drained. Both twins survived and were delivered in good condition in gestational week 35. We recommend ultrasound-guided amniocentesis to be performed in twin pregnancy affected by acute polyhydramniosis.
