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.
宫角异位妊娠是一种罕见的情况，在所有异位妊娠中占2%-4%，估计每2500至5000例分娩中就有一例。由于妊娠晚期着床部位的生长和继发破裂，导致严重的血流动力学失代偿，它代表着较高的孕产妇死亡率。我们于1989年1月至1994年12月在国家围产医学研究所进行了一项回顾性研究。在报告的35080例分娩中，仅发现6例宫角异位妊娠，在总共149例异位妊娠中也仅发现6例。收集的数据包括产妇年龄、诊断时的孕周、体征和症状、手术治疗并发症以及组织病理学报告。平均产妇年龄为31.5岁，诊断时的孕周在7.1至24周之间。所有患者均出现弥漫性腹痛和闭经，2例有经阴道出血。100%的病例需要行全腹子宫切除术作为手术治疗，发现的最重要并发症是休克，因此未报告孕产妇死亡。我们发现该病理情况在我们机构的发生率为每5846例分娩中有1例，占所有异位妊娠的0.01%，我们发现其发生率为4.02%，与世界文献一致。
