Successful management of three cases of interstitial pregnancies with local instillation of potassium chloride: Avoiding a potential cornuostomy

Research output: Contribution to journalArticlepeer-review

Abstract

Here, we present three cases of women with interstitial pregnancy who were managed with local instillation of potassium chloride. These women were in their 20s-30s and presented in stable condition. Of them, two had a history of previous ectopic pregnancy. Interstitial pregnancy was diagnosed by transvaginal sonography which showed an empty uterine cavity with a gestational sac 1 cm away from the lateral edge of the uterine cavity, with <5 mm myometrium surrounding it in all planes. Two of the three cases failed to respond to methotrexate injection. Due to the presence of high-end ultrasound machine and technical expertise, local instillation of potassium chloride was offered as an alternative to surgical treatment, which is definitive, and all three patients had a successful outcome. One patient returned with pain in the abdomen, which required inpatient monitoring and was later diagnosed with urinary tract infection and was given appropriate antibiotics.
