The Implanon was inserted 1 week prior by the patient\u2019s general practitioner who was unable to palpate the Implanon after insertion and hence, ordered an ultrasound scan which showed an actively migrating Implanon in the left basilic vein. She had mild chest pain, and her physical examination, ECG and blood tests were unremarkable. A CT chest showed a 31 mm foreign body within the right lower lobar artery. The foreign body was removed by interventional radiology by accessing the right internal jugular vein under ultrasound guidance and inserting a 6 FR pig catheter into the pulmonary trunk. The position was confirmed with angiogram and the foreign body was removed using a goose neck snare. The patient was discharged the same day with no complications, and fell pregnant a few months afterwards.<\/jats:p>","DOI":"10.1136\/bcr-2024-261381","type":"journal-article","created":{"date-parts":[[2024,8,14]],"date-time":"2024-08-14T21:25:27Z","timestamp":1723670727000},"page":"e261381","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Early endovascular retrieval of a migrated Implanon NXT from a branch of the right pulmonary artery"],"prefix":"10.1136","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-6661-3955","authenticated-orcid":false,"given":"Michelle","family":"Borg","sequence":"first","affiliation":[{"name":"Obstetrics and Gynaecology, Gold Coast Hospital and Health Service, Southport, Queensland, Australia"},{"name":"Griffith University, Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mathusi","family":"Swaminathan","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynaecology, Gold Coast Hospital and Health Service, Southport, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Johnson","family":"Cheuk","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynaecology, Gold Coast Hospital and Health Service, Southport, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanne","family":"Michael","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynaecology, Gold Coast Hospital and Health Service, Southport, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Graeme","family":"Walker","sequence":"additional","affiliation":[{"name":"Obstetrics and Gynaecology, Gold Coast Hospital and Health Service, Southport, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2024,8,14]]},"reference":[{"key":"2025082713233954000_17.8.e261381.1","doi-asserted-by":"crossref","DOI":"10.1136\/bcr-2017-219259","article-title":"Migration of a nexplanon contraceptive implant to the pulmonary artery","volume":"2017","author":"Barlow-Evans","year":"2017","journal-title":"BMJ Case Rep"},{"key":"2025082713233954000_17.8.e261381.2","doi-asserted-by":"crossref","first-page":"62","DOI":"10.1016\/j.contraception.2022.03.017","article-title":"Management of etonogestrel implant migration into the pulmonary artery","volume":"113","author":"Clermidy","year":"2022","journal-title":"Contraception"},{"key":"2025082713233954000_17.8.e261381.3","doi-asserted-by":"crossref","first-page":"186","DOI":"10.1016\/j.contraception.2020.05.006","article-title":"Incidence and characteristics of intravascular pulmonary migration of etonogestrel implants: a french nationwide study","volume":"102","author":"Simon","year":"2020","journal-title":"Contraception"},{"key":"2025082713233954000_17.8.e261381.4","first-page":"485","article-title":"Location and removal of non-palpable subdermal single-rod contraceptive implant","volume":"88","author":"Buitr\u00f3n-Garc\u00eda-Figueroa","year":"2020","journal-title":"Cir Cir"},{"key":"2025082713233954000_17.8.e261381.5","doi-asserted-by":"crossref","first-page":"965","DOI":"10.31083\/j.ceog.2020.06.5518","article-title":"Removal of a migrated subdermal contraceptive implant: a case report and review of the literature","volume":"47","author":"Capell-Morell","year":"2020","journal-title":"Clin Exp Obstet Gynecol"},{"key":"2025082713233954000_17.8.e261381.6","doi-asserted-by":"crossref","first-page":"57","DOI":"10.2147\/OAJC.S165827","article-title":"Percutaneous extraction of an embolized progesterone contraceptive implant from the pulmonary artery","volume":"9","author":"Akhtar","year":"2018","journal-title":"Open Access J Contracept"},{"key":"2025082713233954000_17.8.e261381.7","first-page":"21","article-title":"Ulnar nerve injury on removal of a contraceptive implant","volume":"260","author":"O\u2019Grady","year":"2016","journal-title":"Pract"},{"key":"2025082713233954000_17.8.e261381.8","doi-asserted-by":"crossref","first-page":"59","DOI":"10.1016\/j.diii.2018.08.006","article-title":"Migration of implanon contraceptive implant into the pulmonary artery","volume":"100","author":"Cerato","year":"2019","journal-title":"Diagn Interv Imaging"},{"key":"2025082713233954000_17.8.e261381.9","doi-asserted-by":"crossref","first-page":"215","DOI":"10.1016\/j.contraception.2016.11.004","article-title":"Looking for a lost subdermal contraceptive implant?
