Heterotopic pregnancy is the simultaneous coexistence of both intrauterine and extrauterine pregnancies. Cornual heterotopic pregnancies can cause catastrophic haemorrhage because of their location. Available evidence suggests that they have usually been managed surgically by laparotomy and cornual resection, few were managed medically and two expectantly. Of the surgical group, only three underwent laparoscopic management. We report the first case of successful management of cornual heterotpic pregnancy by Harmonic ACE® and a favourable outcome of the intrauterine pregnancy.
