Treatment of early heterotopic interstitial (cornual) gestation with subsequent delivery of an intrauterine pregnancy--case report.

We present the case of a 38-year-old woman who was treated for a heterotopic interstitial (cornual) pregnancy diagnosed at the 7th week of gestation. The intervention was performed via transvaginal ultrasound-guided aspiration and instillation of a hypertonic solution of sodium chloride into the cornual sac. The heterotopic comrnual pregnancy was successfully aborted, and the intrauterine pregnancy was successfully maintained with delivery of a healthy newborn.
