[The special case: rare gynecologic emergency of uterine perforation in placenta percreta].

The term placenta percreta signifies a penetration of placenta villus growing through the myometrial wall to the serosal side. The incidence has been reported to vary between 1:1000 to 1:70 000. Thus uteral rupture as a result of placenta percreta is a rare event. Signs of severe shock as leading signs predominate. Immediate laparotomy with hysterectomy is the therapy of choice. The final diagnosis is based on histology.
