title: [Cornual pregnancy].
abstract: Cornual ectopic pregnancy is a rare entity, found in 2-4% of all ectopic pregnancies, with an estimates incidence of one in every 2500 to 5000 deliveries. It represents a high rate of maternal mortality because of the growth and secondary rupture of the zone of implantation in advanced gestational ages, resulting in severe hemodynamic decompensation. We realizes a retrospective study from January 1989 to December 1994 at Instituto Nacional de Perinatologia. Only 6 cases of ectopic cornual pregnancies were found out of 35,080 deliveries reported, and of 149 ectopic pregnancies in general. Maternal age, gestational age at time of diagnosis, signs and symptoms, surgical treatment complications, and histopathologic report were some of the data collected. Maternal age in average was found to be 31.5, gestational age at time of diagnosis between 7.1 to 24 weeks. All patients referred diffuse abdominal pain and amenorrhea, with 2 cases of transvaginal bleeding. The 100% of cases required total abdominal hysterectomy as surgical treatment, and the most important complication found was shock, hence no maternal deaths were reported. We found this pathology to have an incidence of 1 of 5846 deliveries at our Institution, representing the 0.01% Of all ectopic pregnancies, we found to have an incidence of 4.02% that agrees with world literature.
