Successful unwinding of large, hyperstimulated, ischaemic-haemorrhagic adnexa by laparoscopy during the second trimester of pregnancy is described. Three women in their second trimester of pregnancy were treated by laparoscopy. In all cases, the ovaries were unwound and replaced in their anatomical position. Shortly after the procedure they became pink. Serial ultrasound examinations showed viable, intrauterine fetuses and ovaries with normal blood flow. Laparoscopic ovarian detorsion is a safe and easy procedure, and can be carried out in advanced gestation until approximately 20th week if special safety measures are adhered to.
