It occurs due to abnormal placental vascular anastomoses, allowing retrograde perfusion from healthy \u201cpump\u201d twin to severely malformed twin lacking a functional heart. The prognosis is poor; mortality is 100% in the acardiac twin and 50%\u201355% in the pump twin. We present a case of 30\u2010year\u2010old gravida 3 parity 1 with previous 1 abortion (G3 P1 A1) having an acephalus acardiac twin diagnosed during routine second trimester ultrasound scan. Because there were no signs of hemodynamic compromise in the normal twin and pregnancy was continued up to 38\u2009weeks of gestation when elective lower segment cesarean section was done. This case emphasizes conservative management of TRAP sequence if there is no risk of hydrops or cardiac failure in the pump twin.<\/jats:p>","DOI":"10.1002\/ccr3.73218","type":"journal-article","created":{"date-parts":[[2026,7,23]],"date-time":"2026-07-23T07:36:14Z","timestamp":1784792174000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Managing\n                    <scp>TRAP<\/scp>\n                    Sequence Conservatively: A Case Report of Full\u2010Term Pregnancy With Favorable Outcome"],"prefix":"10.1002","volume":"14","author":[{"given":"Bishal","family":"Khaniya","sequence":"first","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-6203-3593","authenticated-orcid":false,"given":"Ayush","family":"Shrestha","sequence":"additional","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anish","family":"Sah","sequence":"additional","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rita","family":"Adhikari","sequence":"additional","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8767-4240","authenticated-orcid":false,"given":"Sujata","family":"Bhandari","sequence":"additional","affiliation":[{"name":"Nobel Medical College  Biratnagar Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aashish","family":"Bhandari","sequence":"additional","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ram","family":"Aryal","sequence":"additional","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sameep","family":"Sapkota","sequence":"additional","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Puspa Raj","family":"Bham","sequence":"additional","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6382-1082","authenticated-orcid":false,"given":"Madhur","family":"Bhattarai","sequence":"additional","affiliation":[{"name":"Institute of Medicine Tribhuvan University  Kathmandu Nepal"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,23]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.2147\/IJWH.S214254"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/ccr3.70052"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/diagnostics13193109"},{"issue":"11","key":"e_1_2_14_5_1","article-title":"Twin Reversed Arterial Perfusion","volume":"14","author":"Hans P.","year":"2022","journal-title":"Cureus"},{"issue":"3","key":"e_1_2_14_6_1","doi-asserted-by":"crossref","DOI":"10.5812\/iranjradiol.12(3)2015.14979","article-title":"Twin Reversed Arterial Perfusion (TRAP) Sequence; Characteristic Gray\u2010Scale and Doppler Ultrasonography Findings","volume":"12","author":"Buyukkaya A.","year":"2015","journal-title":"Iranian Journal of Radiology: A Quarterly Journal Published by the Iranian Radiological Society"},{"issue":"8","key":"e_1_2_14_7_1","first-page":"254","article-title":"A Rare Case of Acardiac Twin: A Case Report","volume":"2","author":"Prameela R.
