Intrafetal prostaglandin F2 alpha administration for midtrimester pregnancy termination: a case report.

An original route for prostaglandin F2 alpha administration for midtrimester pregnancy termination is presented. The diagnosis of nuchal cystic hygroma in a hydropic fetus with severe oligohydramnios was made by real-time ultrasonography. Forty milliliters of fluid was aspirated for laboratory studies and prostaglandin F2 alpha was injected into the nuchal cysts to induce abortion. The pregnancy was successfully terminated 8 hours later.
