Abstract
Late pregnancy termination by continuous extraovular instillation of prostaglandin F2.alpha. (PGF2.alpha.) was successfully performed in 13 patients with previous cesarean section (CS) delivery. The indictions for pregnancy termination were intrauterine fetal demise in nine patients, social indications in two patients, Down''s Syndrome in one patient and quadruplets pregnancy in one patient. One patient had a previous classical vertical cesarean section, two had two previous and one three previous low segment transverse (LST) cesarean sections. The other nine patients had one previous low segment transverse cesarean section. The instillation of prostaglandin solution was obtained by using a new double balloon catheter designed for extraovular pregnancy terminations. All patients aborted following the procedure with no complications. The instillation abortion time ranged from 5 1/2 to 20 h (mean 13.3 h).
