RESUMO
OBJECTIVE: To present 13 cases of unruptured tubal ectopic pregnancies successfully treated with ultrasound-guided aspiration and local and systemic methotrexate (MTX) administration. DESIGN: Case series. SETTING: University hospital. PATIENT(S): Thirteen women with an unruptured tubal ectopic pregnancy. INTERVENTION(S): Transvaginal ultrasound-guided aspiration of the tubal ectopic pregnancy followed by MTX administration into the gestational sac (half of the calculated total dose of 25 mg/m(2)) and intramuscular injection (the remaining half of the calculated total dose of 25 mg/m(2)). MAIN OUTCOME MEASURE(S): Recovery of the patients, successful conservative treatment of the tubal ectopic pregnancies with preservation of the fallopian tubes. RESULT(S): Twelve (92%) of 13 women were successfully aborted, without need for salpingectomy or salpingostomy. CONCLUSION(S): Transvaginal ultrasound-guided aspiration of fetus followed by local and systemic methotrexate administration can be safely used to treat unruptured tubal ectopic pregnancies.
