Treatment of unruptured tubal pregnancy by local injection of methotrexate and prostaglandin F2 alpha in 52 patients.
Uncomplicated tubal pregnancies were treated by local injection of methotrexate (25 to 50 mg) and PGF2 alpha (5 to 10 mg). Trophoblastic resorption occurred in 50 (96.1%) of 52 patients within 20 days after treatment and without side effects. Three months after treatment, the affected tube was patent in 43 (91.4%) of 47 patients continuing in the study, and the subsequent intrauterine pregnancy rate was 40.4%. The combined use of methotrexate and PGF2 alpha appears to be a promising treatment for tubal pregnancy and should be evaluated further.
