Covered stent-graft placement can provide rapid hemostasis while preserving arterial patency. However, implantation in a contaminated field adjacent to a tracheostoma may predispose patients to devastating device-related infection, particularly in immunocompromised hosts.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Case presentation<\/jats:title>\n                    <jats:p>\n                      We report the case of a 35-year-old man with stage IVB thymic carcinoma (T4N2M0) who received induction chemotherapy combined with immunotherapy followed by extended resection, including segmental tracheal resection, right thyroid lobectomy with isthmusectomy, supraclavicular island flap tracheal reconstruction, and tracheostomy. Thirteen days after discharge, he developed massive hemoptysis consistent with CBS and underwent emergency neck exploration, angiography, and placement of covered stent grafts in the right common carotid and right subclavian arteries. During the subsequent course, he developed recurrent fever, and repeated blood cultures grew\n                      <jats:italic>Pseudomonas aeruginosa<\/jats:italic>\n                      . Despite culture-directed antipseudomonal therapy and removal of indwelling central venous catheters, bacteremia recurred. Flexible fiberoptic laryngoscopy later demonstrated exposure of the vascular stent graft into the airway, strongly suggesting stent-graft infection or bacterial colonization of the exposed device. The patient subsequently developed recurrent bleeding through the tracheostoma and persistent bacteremia, followed by massive hemorrhage and progressive clinical deterioration. Because definitive surgical source control was judged to offer no acceptable risk-benefit profile after multidisciplinary reassessment, the family elected to withdraw active treatment.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>This case suggests that covered stent placement in a contaminated head-and-neck field should be undertaken with great caution, as subsequent bacterial colonization or stent-graft infection may occur and may further lead to recurrent or even catastrophic hemorrhage. When stent implantation is unavoidable, early multidisciplinary evaluation is essential, and every effort should be made to prevent wound infection, bacterial colonization of the device, and related bleeding complications.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3389\/fmed.2026.1888936","type":"journal-article","created":{"date-parts":[[2026,7,23]],"date-time":"2026-07-23T15:52:13Z","timestamp":1784821933000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Suspected carotid stent-graft infection presenting as recurrent pseudomonas aeruginosa bacteremia after oncologic surgery: a case report"],"prefix":"10.3389","volume":"13","author":[{"given":"Xiaoqin","family":"Ji","sequence":"first","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, West China Hospital, Sichuan University\/West China School of Nursing, Sichuan University, Sichuan Province","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ziyan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, West China Hospital, Sichuan University, Sichuan Province","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiqi","family":"Yuan","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, West China Hospital, Sichuan University\/West China School of Nursing, Sichuan University, Sichuan Province","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huiling","family":"Zhao","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, West China Hospital, Sichuan University\/West China School of Nursing, Sichuan University, Sichuan Province","place":["Chengdu, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,7,23]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"S260","DOI":"10.1097\/JTO.0b013e3181f1f62d","article-title":"Epidemiology of thymoma and associated malignancies","volume":"5","author":"Engels","year":"2010","journal-title":"J Thorac Oncol."},{"key":"B2","doi-asserted-by":"publisher","first-page":"123","DOI":"10.1016\/j.ejca.2007.11.004","article-title":"Thymic epithelial tumours: a population-based study of the incidence, diagnostic procedures and therapy","volume":"44","author":"de Jong","year":"2008","journal-title":"Eur J Cancer"},{"key":"B3","doi-asserted-by":"publisher","first-page":"419","DOI":"10.1007\/s00432-021-03620-8","article-title":"Multi-institutional survey of thymic carcinoma patients in Hokushin region","volume":"148","author":"Uramoto","year":"2022","journal-title":"J Cancer Res Clin Oncol"},{"key":"B4","doi-asserted-by":"publisher","first-page":"332","DOI":"10.1016\/j.critrevonc.2016.01.012","article-title":"Thymoma and thymic carcinomas","volume":"99","author":"Scorsetti","year":"2016","journal-title":"Crit Rev Oncol Hematol"},{"key":"B5","doi-asserted-by":"publisher","first-page":"1219","DOI":"10.4103\/jcrt.jcrt_586_21","article-title":"Clinicopathological factors affecting the prognosis of massive hemorrhage after radiotherapy for patients having nasopharyngeal carcinoma","volume":"17","author":"Huang","year":"2021","journal-title":"J Cancer Res Ther"},{"key":"B6","doi-asserted-by":"publisher","first-page":"1083","DOI":"10.1016\/j.ijrobp.2010.08.029","article-title":"Risk of carotid blowout after reirradiation of the head and neck: a systematic review","volume":"82","author":"McDonald","year":"2012","journal-title":"Int J Radiat Oncol Biol Phys."},{"key":"B7","doi-asserted-by":"publisher","first-page":"105723","DOI":"10.1016\/j.oraloncology.2022.105723","article-title":"Predictors of survival following carotid blowout syndrome","volume":"125","author":"Silverman","year":"2022","journal-title":"Oral Oncol"},{"key":"B8","doi-asserted-by":"publisher","first-page":"1086","DOI":"10.1016\/S1470-2045(08)70278-X","article-title":"Alt-Epping.
