单角子宫(uuicornuate uterus or semiuterus)伴残角(rudimentary horn)是一种罕见的子宫畸形,系因胚胎发育时期两侧米勒氏管的融合过程发生障碍所致。两个子宫之间通常有一纤维或纤维肌肉带将其相连,但80％～90％病例无管道相通。此种畸形少见,文献多限于个案报道,本文总结我院病例,并重点讨论残角妊娠的诊断和处理。 资料与方法 本院自1980年1月至1992年12月,共见子宫畸形143例,其中单角伴残角子宫畸形共26例,占18.2％,Buttram和Gibbons将米勒氏管发育异常其分六类。单角子宫畸形属第Ⅱ数,如伴有残角则为 Uterus horn (uuicornuate uterus or semiuterus) Rudimentary horn (rudimentary horn) is a rare uterine malformation, due to the embryonic development on both sides of the Miller tube fusion process due to obstacles. There is usually a fibrous or fibrous muscle band connecting the two uteruses, but 80% to 90% of the cases are non-communicating. This deformity rare, the literature is limited to case reports, this article summarizes the hospital cases, and focus on the diagnosis and treatment of ruffled pregnancy. Materials and Methods The hospital from January 1980 to December 1992, a total of 143 cases of uterine malformations were observed, of which 26 cases of unilateral horn remnant uterine malformations, accounting for 18.2%, Buttram and Gibbons the Miller’s duct dysplasia Divided into six categories. Single-angle uterine malformations are number Ⅱ, as with the residual angle is
