We encountered a case where flushing the TIVAP catheter became impossible because of resistance. A 61-year-old-woman underwent TIVAP placement. Although a chest X-ray revealed the fractured catheter had migrated into the right hilar area, the timing of the fracture was unclear. Four-dimensional computed tomography (4D-CT) showed that the tip of the fractured catheter was located at the anterior segmental artery of the right upper lobe and was immobile, with the remaining portion flapping with the blood flow. Transcatheter removal of the migrated catheter was judged to be possible and was performed successfully. 4D-CT may be useful as an appropriate approach in transcatheter removal of a migrated fractured catheter.<\/jats:p>","DOI":"10.1136\/bcr-2017-221445","type":"journal-article","created":{"date-parts":[[2017,8,1]],"date-time":"2017-08-01T03:37:43Z","timestamp":1501558663000},"page":"bcr-2017-221445","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Four-dimensional CT-guided transcatheter removal of a fractured migrated catheter of a totally implantable venous access port"],"prefix":"10.1136","volume":"2017","author":[{"given":"Kazushi","family":"Fujimoto","sequence":"first","affiliation":[{"name":"Department of Medicine, School of Medicine, Chiba University, Chiba, Chiba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hajime","family":"Kasai","sequence":"additional","affiliation":[{"name":"Department of Respirology, Graduate School of Medicine, Chiba University, Chiba, Chiba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toshihiko","family":"Sugiura","sequence":"additional","affiliation":[{"name":"Department of Respirology, Graduate School of Medicine, Chiba University, Chiba, Chiba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Koichiro","family":"Tatsumi","sequence":"additional","affiliation":[{"name":"Department of Respirology, Graduate School of Medicine, Chiba University, Chiba, Chiba, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2017,8,1]]},"reference":[{"key":"2025082622541833000_2017.jul31_1.bcr-2017-221445.1","doi-asserted-by":"publisher","DOI":"10.1258\/rsmvasc.13.2.120"},{"key":"2025082622541833000_2017.jul31_1.bcr-2017-221445.2","doi-asserted-by":"crossref","first-page":"50","DOI":"10.1186\/s13019-016-0450-y","article-title":"Spontaneous fracture and migration of catheter of a totally implantable venous access port via internal jugular vein--a case report","volume":"11","author":"Ko","year":"2016","journal-title":"J Cardiothorac Surg"},{"key":"2025082622541833000_2017.jul31_1.bcr-2017-221445.3","doi-asserted-by":"crossref","first-page":"2403","DOI":"10.1007\/s00268-011-1200-x","article-title":"Catheter fracture of intravenous ports and its management","volume":"35","author":"Wu","year":"2011","journal-title":"World J Surg"},{"key":"2025082622541833000_2017.jul31_1.bcr-2017-221445.4","doi-asserted-by":"crossref","first-page":"182","DOI":"10.9738\/INTSURG-D-13-00185.1","article-title":"A comparison of outcomes and complications of totally implantable access port through the internal jugular vein versus the subclavian vein","volume":"99","author":"Nagasawa","year":"2014","journal-title":"Int Surg"},{"key":"2025082622541833000_2017.jul31_1.bcr-2017-221445.5","doi-asserted-by":"publisher","DOI":"10.1148\/radiol.10100245"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr-2017-221445","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,8,27]],"date-time":"2025-08-27T05:54:21Z","timestamp":1756274061000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr-2017-221445"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,8,1]]},"references-count":5,"alternative-id":["10.1136\/bcr-2017-221445"],"URL":"https:\/\/doi.org\/10.1136\/bcr-2017-221445","relation":{},"ISSN":["1757-790X"],"issn-type":[{"type":"electronic","value":"1757-790X"}],"subject":[],"published":{"date-parts":[[2017,8,1]]}}}
