XXXX : report of three cases.

@entity1 @entity3152 @entity26370
OBJECTIVE: @entity26370 , defined as concomitant intrauterine and ectopic pregnancy, is a rare event. Assisted reproductive technologies have led to an increase in the number of @entity26370 . MATERIALS AND METHOD: From 1997 to 1999 three cases of @entity26370 were referred to the gynecological unit of the hospital of St. P  lten. The condition was diagnosed at 7, 8 and 12 weeks of gestation, respectively. Two @entity1 had undergone assisted reproductive technologies and former pelvic surgery for tubal pregnancy. Two @entity1 had intrauterine singleton pregnancies and one @entity1 had an intrauterine twin pregnancy. In all cases the ectopic site presented as a ruptured tubal pregnancy and the treatment consisted of laparoscopic salpingectomy. RESULTS: In all @entity1 the postoperative course was uneventful and the intrauterine pregnancy progressed. In one case recurrent @entity3152 led to vaginal delivery at 33 weeks of pregnancy. In the case of twin pregnancy, a planned cesarean section was performed at 37 weeks of gestation. One @entity1 delivered at term. All newborns were healthy. CONCLUSION: Knowledge of heterotopic pregnancy and understanding the epidemiological risk factors underlying this condition are important for early diagnosis with the aim of improving therapy and clinical outcome.
