Transvaginal instillation of potassium chloride or methotrexate under ultrasound guidance is a treatment for ectopic pregnancy. While effective for some, close ultrasound follow-up is crucial due to variable outcomes.

Area of Science:

  • Reproductive Medicine
  • Gynecologic Surgery
  • Medical Imaging

Background:

  • Early diagnosis of ectopic pregnancy is improved by vaginal ultrasonography and human chorionic gonadotropin (hCG) assays.
  • Ectopic pregnancy management includes surgery, medical therapy, and observation.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of transvaginal instillation of potassium chloride or methotrexate for treating ectopic pregnancy under sonographic guidance.
  • To present a treatment protocol based on clinical experience.

Main Methods:

  • Retrospective review of 12 cases of ectopic pregnancy treated with transvaginal instillation of potassium chloride or methotrexate.
  • Treatment was guided by ultrasound.
  • Patients were monitored with serial hCG levels and ultrasound follow-up.

Main Results:

  • Three out of 12 patients (25%) required subsequent laparotomy.
  • One of two patients (50%) receiving potassium chloride and two of six patients (33.3%) receiving methotrexate required laparotomy.
  • Beta-hCG levels were unreliable for predicting treatment outcomes.

Conclusions:

  • Transvaginal instillation of potassium chloride or methotrexate can be a treatment option for selected ectopic pregnancies.
  • Close ultrasound monitoring is essential for managing patients treated with this method.
  • A standardized protocol for treatment and follow-up is recommended.
