Background: Heterotopic pregnancy is the condition in which intrauterine and ectopic pregnancy coexist. The conservative management of the ectopic pregnancy, with the intrauterine pregnancy preserved, has been reported. Case(s): Here, we report a very rare case: intrauterine and cervical pregnancy coexist: intrasacular Potassium chloride (KCL) injection successfully terminated cervical pregnancy with intrauterine pregnancy preserved, but later massive bleeding occurred from the cervix. A 39-year-old woman at 7+1 weeks was diagnosed with a heterotopic cervical gestation, with intrauterine and cervical sac, both with live embryos. The ectopic pregnancy was successfully terminated with intrasacular injection of KCl, preserving the intrauterine pregnancy. At 32+4 weeks of gestation the patient started with a profuse bleeding from the cervical sac, causing maternal hypotension (80/45 mmHg) and tachycardia (160 bpm) and a decelerative pattern in the cardiotocographic fetal monitoring, prompting us to perform caesarean section. The cessation of bleeding was achieved using a double balloon intracervical catheter, which was withdrawn 24 hours after its insertion without observing a new bleeding episode. The patient was discharged after 8 days and the newborn after 35 days of life, both in good health. Conclusions: Conservative treatment of a heterotopic gestation is possible, managing to preserve the viability of the intrauterine pregnancy.
