Assisted reproductive technology has improved twin pregnancy rates with the use of ovulation\u2010inducing drugs. The risk factor of twins is much higher than singletons, and adverse pregnancy outcomes such as stillbirth and premature birth are more likely to occur than singletons, especially the special complications of monochorionic twins (MC), and the neonatal mortality and morbidity are also increased. Prenatal diagnosis and prognosis of twin pregnancy, as well as therapeutic interventions, are of current concern. Ultrasound can realize the understanding of intrauterine growth and development of twin pregnancy fetuses during pregnancy, can more accurately determine gestational age, organ function, and maturity, and timely detect fetal growth and development abnormalities in twin pregnancy, while the prognosis and treatment still need further improvement. The purpose of this study was to investigate the clinical value and treatment progress of prenatal ultrasound monitoring in twin pregnancy.<\/jats:p>","DOI":"10.1155\/2022\/6748487","type":"journal-article","created":{"date-parts":[[2022,8,22]],"date-time":"2022-08-22T16:05:23Z","timestamp":1661184323000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Clinical Value and Treatment Progress of Prenatal Ultrasonography in Twin Pregnancy: A Systematic Review"],"prefix":"10.1155","volume":"2022","author":[{"given":"Lihua","family":"Zou","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianzheng","family":"Yang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aiping","family":"Min","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Yin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2444-0890","authenticated-orcid":false,"given":"Minxing","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2022,8,22]]},"reference":[{"volume-title":"Multiple Pregnancy: The Management of Twin and Triplet Pregnancies in the Antenatal Period[M]","year":"2011","author":"National Collaborating Center for Women\u2019s and Children\u2019s Health (UK)","key":"e_1_2_8_1_2"},{"key":"e_1_2_8_2_2","first-page":"1","article-title":"Births: preliminary data for 2009[J]","volume":"59","author":"Hamilton B.
