Spontaneous rupture of the uterus due to placenta percreta; a case report.

Placenta percreta is a rare but serious complication of pregnancy, and is rarely diagnosed in the second trimester of pregnancy. We report a very rare case of placenta percreta accompanied by spontaneous uterine rupture at 25-weeks of gestation. A 30-year-old woman with severe abdominal pain was admitted to our hospital at 25 weeks of gestation. A laparotomy was immediately performed because of intraabdominal bleeding. The uterus revealed a perforation of the fundus. A supra-vaginal hysterectomy was performed. A pathological investigation of the uterus revealed placenta percreta. The patient had neither gravity nor any prior uterine operation. It is very rare for placenta percreta to be recognized in a primigravida woman or in the second trimester of pregnancy.
