Full-term interstitial retroperitoneal pregnancy with delivery of a healthy infant

Ectopic pregnancy adjacent to iliac vessels managed successfully by minimally invasive treatment using local methotrexate injection: An extremely rare case and literature review

A case report of successfully treated retroperitoneal ectopic pregnancy (REP) is presented. A 36-year-old woman, gravida 3, para 2, was admitted to hospital for suspected ectopic pregnancy with light vaginal bleeding and mild abdominal pain for 3 days at 45 days of gestation by the last menstrual period.Multiple transvaginal ultrasonography and two times laparoscopic probes led to the diagnosis of REP located to the iliac blood vessels closely. Eventually the patient was cured with the treatment using local methotrexate injection under real-time ultrasound guidance and systemic methotrexate administration. We also summarized another 31 cases of REP to further understand this disease, sharing them to arouse clinical attention for the diagnosis and treatment of REP timely.

Interstitial Pregnancy in the Third Trimester with Severe Preeclampsia: A Case Report and Literature Review

An interstitial pregnancy that continues beyond the second trimester is a rare phenomenon. We report a patient with an interstitial pregnancy undiagnosed until the third trimester. A multiparous woman was referred to us because of preeclampsia at 26 weeks of gestation. The placental position was the right fundus, and color Doppler ultrasound revealed myometrial thinning and subplacental hypervascularity, leading to a suspicion of placenta accreta spectrum (PAS). Emergency cesarean section was performed at 28^1/7 weeks of gestation due to severe preeclampsia. The right tubal horn to the isthmus of the fallopian tube bulged with placental adhesion and a part of the tube had ruptured, with the omentum adhering to the ruptured part. Interstitial and tubal isthmic pregnancy with uterine rupture was diagnosed.

An evident asymmetrical uterus during cesarean delivery

If an obstetrician determines the presence of an asymmetrical uterus during cesarean delivery, the likelihood of an interstitial pregnancy complicated by placenta accreta should be considered. The figures in this article should help advance the current knowledge about a rare type of full-term interstitial pregnancy complicated by placenta accreta.

Interstitial pregnancy resulting in a viable infant coexistent with massive perivillous fibrin deposition: a case report and literature review

Objective The objective of this report is to describe a rare case of interstitial pregnancy ultimately resulting in a viable infant coexistent with massive perivillous fibrin deposition (MPFD). Study Design This study is a case report and literature review. Results A 35-year-old female patient underwent cesarean section at 32 weeks of gestation due to fetal growth restriction (FGR) and breech presentation. During the operation, a diagnosis of interstitial pregnancy was established. There was no evidence of placental separation. We decided to complete surgery without removal of the placenta and waited until the placenta delivered spontaneously. The conservative management was successful, and the patient was discharged on postoperative day 13. The pathologic examination showed MPFD. Conclusion If interstitial pregnancies are not diagnosed at an early gestational age, it can result in a viable fetus, but such pregnancies may be associated with FGR or placenta accreta.
