Pregnant noncommunicating rudimentary uterine horn with placenta percreta.

Abstract

BACKGROUND: To report a placenta percreta in a 7-week gestational rudimentary noncommunicating uterine horn pregnancy. METHODS: A 28-year-old woman with no complaints presented with a rudimentary uterine horn pregnancy at 7-weeks gestation. The diagnosis was suspected by ultrasonography and diagnosed by laparoscopy. Laparoscopic excision of the rudimentary uterine horn and ipsilateral salpingectomy were performed, as well as biopsy of several peritoneal endometriosis lesions. RESULTS: A 7-week gestation pregnancy with placenta percreta was identified in the rudimentary uterine horn. No communication was found with the right unicornuate uterus. Endometriosis was confirmed. Clinical outcome was favorable. CONCLUSION: Placenta percreta may occur in rudimentary uterine horn pregnancies, but accidents may be avoided by an early diagnosis and surgical management. However, in young women who desire pregnancy, planned laparoscopic resection of a rudimentary uterine horn revealed accidentally should be discussed.
