摘要：Placenta percreta is still a life threatening condition due to the risk of excessive bleeding. Furthermore, it confers a considerable risk of the patient losing her uterus. An improved diagnosis including assessment of the depth of myometrial and serosal invasion is now available by color Doppler imaging, making the planning of elective caesarean section possible. We have designed a new operating technique, by which we successfully have achieved haemostasis of the areas containing the uterine arteries as well as the area between the bladder and the uterine cervix.
