Efficacy of transvaginal ultrasound-guided local injections of absolute ethanol for ectopic pregnancies with intrauterine implantation sites

Figure 1 Transvaginal ultrasonography findings (case 11: interstitial tubal pregnancy) and transvaginal ultrasonography findings after local injections of absolute ethanol. A: Although a 20-mm gestation sac was observed in the interstitial portion of the left fallopian tube separated from the endometrium, no fetal heartbeat was observed; B: Absolute ethanol local injection site using a 21-gauge oocyte collection needle. Local absolute ethanol injections were performed in the guide sheath periphery of the interstitial tubal pregnancy site using transvaginal ultrasound guidance.
