Pregnancy of Remnant Horn Uterus and Rupture of Remnant Horn Uterus Found During Operation: A Case Report

残角子宫妊娠(rudimentary uterine horn pregnancy, RHP)主要指受精卵在残角子宫内着床并发育的过程，是一种极为少见的异位妊娠，其发生率约为1/76,000~140,000。在妊娠早期常没有典型的临床症状，患者多在产检时发现或伴有下腹痛、阴道流血等症状就诊时被发现。随着妊娠周数增加，常会发生自发性破裂，从而引起腹腔内大出血、失血性休克等，如诊治不及时甚至导致孕妇死亡。本文将报道1例延安大学附属医院收治的残角子宫妊娠19周破裂病例。
Rudimentary uterine horn pregnancy (RHP), the implantation and development of a fertilized egg in the uterus, is an extremely rare ectopic pregnancy, varying in incidence from 1 in 76,000 to 140,000. There are often no typical clinical symptoms in early pregnancy, and patients are often found during labor examination or accompanied by symptoms such as lower abdominal pain and vaginal bleeding. With the increase of gestation weeks, spontaneous rupture often occurs, resulting in abdominal bleeding, hemorrhagic shock, if no timely diagnosis and treatment even leading to death of pregnant women. This paper reports a case of uterine rupture of residual horn at 19 weeks of gestation in The Affiliated Hospital of Yan’an University.
