The patient presented with lower abdominal pain and underwent laparoscopic surgery in which the gestational tissue was removed without excision of the rudimentary horn and ipsilateral fallopian tube. Unicornuate uteri often coexist with rudimentary horns, most of which are non-communicating. RHP is rare, and symptomatic women tend to complain of abdominal pain. Once RHP is suspected, the clinician should monitor the patient for signs of hypovolemic shock, such as hypotension, because the RHP can rupture owing to the poorly developed musculature. Early surgical intervention with removal of the rudimentary horn along with the ipsilateral fallopian tube is generally suggested to prevent future ectopic pregnancy. The theory of sperm transmigration from the contralateral oviduct has been hypothesized in non-communicating RHP.<\/jats:p>","DOI":"10.3390\/diagnostics12030759","type":"journal-article","created":{"date-parts":[[2022,3,21]],"date-time":"2022-03-21T13:24:59Z","timestamp":1647869099000},"page":"759","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Pregnancy in a Non-Communicating Rudimentary Horn of Unicornuate Uterus"],"prefix":"10.3390","volume":"12","author":[{"given":"Yi-Cih","family":"Ma","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Tung\u2019s Taichung MetroHarbor Hospital, Taichung 435, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2484-3761","authenticated-orcid":false,"given":"Kim-Seng","family":"Law","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Tung\u2019s Taichung MetroHarbor Hospital, Taichung 435, Taiwan"},{"name":"Department of Nursing, Jenteh Junior College of Medicine, Nursing and Management, Miaoli 356, Taiwan"},{"name":"Department of Post-Baccalaureate Medicine, College of Medicine, National Chung Hsing University, Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,3,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Li, X., Peng, P., Liu, X., Chen, W., Liu, J., Yang, J., and Bian, X.
