We report the case of a 20s gravida 2, para 1 woman who underwent ultrasound-guided percutaneous microwave ablation (MWA) at 25 weeks of gestation to interrupt flow to the intra-abdominal umbilical cord vessels of the acardiac twin. Successful cessation of blood flow was achieved. This case highlights the feasibility and clinical potential of MWA as an alternative to conventional modalities in the management of TRAP sequence.<\/jats:p>","DOI":"10.1136\/bcr-2024-264109","type":"journal-article","created":{"date-parts":[[2025,5,15]],"date-time":"2025-05-15T23:45:21Z","timestamp":1747352721000},"page":"e264109","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Microwave ablation for twin-reversed arterial perfusion sequence"],"prefix":"10.1136","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5062-7328","authenticated-orcid":false,"given":"Kiattisak","family":"Kongwattanakul","sequence":"first","affiliation":[{"name":"Department of Obstetrics and Gynecology, Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ratana","family":"Komwilaisak","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anucha","family":"Ahooja","sequence":"additional","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monsicha","family":"Somjit","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2025,5,15]]},"reference":[{"key":"2025082803490631000_18.5.e264109.1","first-page":"1105","article-title":"Detection of twin reversed arterial perfusion sequence at the time of first-trimester screening: the added value of 3-dimensional volume and color Doppler sonography","volume":"27","author":"Bornstein","year":"2008","journal-title":"J Ultrasound Med Off J Am Inst Ultrasound Med"},{"key":"2025082803490631000_18.5.e264109.2","first-page":"647","article-title":"Holoacardius; review of the literature and case report","volume":"2","author":"GILLIM","year":"1953","journal-title":"Obstet Gynecol"},{"key":"2025082803490631000_18.5.e264109.3","doi-asserted-by":"crossref","first-page":"641","DOI":"10.1002\/bdra.23405","article-title":"Twin reversed arterial perfusion sequence is more common than generally accepted","volume":"103","author":"van Gemert","year":"2015","journal-title":"Birth Defects Research"},{"key":"2025082803490631000_18.5.e264109.4","unstructured":"Twin Reversed Arterial Perfusion (TRAP) Sequence: TRAP Sequence | Children\u2019s Wisconsin, 2024.
