Recurrent Ectopic Pregnancy in the Ipsilateral Fallopian Tube Remnant After Salpingectomy for Tubal Pregnancy

Abstract

To report a rare case of recurrent ectopic pregnancy in an ipsilateral fallopian tube remnant after left salpingectomy for tubal pregnancy. A 33-year-old patient presented with suspected ectopic pregnancy. The patient had previously undergone a left salpingectomy for a tubal pregnancy. Laparoscopy revealed ruptured swelling and bleeding from the left fallopian tube remnant. We diagnosed intra-abdominal hemorrhage due to ectopic pregnancy occurring in the fallopian tube remnant following a previous ipsilateral salpingectomy. Most ectopic pregnancies occur in the ampulla of the fallopian tube, but the occurrence of spontaneous ectopic pregnancy in a remnant tube is rare. There are several mechanisms underlying this phenomenon. In this study, we consider both the prevention and treatment of this rare form of ectopic pregnancy.
