A chronically retained macroscopic fragment of radial artery introducer sheath is a very rare complication that has not, to our knowledge, been reported. We report the case of a 62-year-old woman who underwent PCI and developed a persisting infected sinus and abscess at the cannulation site despite multiple courses of antibiotics. Surgical exploration of the forearm recovered a foreign body that was found in the brachioradialis muscle and resembled a fragment of hydrophilic sheath. In conclusion, this case highlights that it is possible to leave macroscopic fragments of hydrophilic sheaths in situ. This is likely to be encountered during difficult access, especially during arterial spasm, and it is advised that the sheath and any other vascular access device is thoroughly inspected following removal.<\/jats:p>","DOI":"10.1136\/bcr-2018-227136","type":"journal-article","created":{"date-parts":[[2019,3,12]],"date-time":"2019-03-12T08:45:22Z","timestamp":1552380322000},"page":"e227136","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Infected chronic sinus secondary to a retained fragment of radial artery introducer sheath following percutaneous coronary intervention (PCI)"],"prefix":"10.1136","volume":"12","author":[{"given":"Christopher George","family":"Ghazala","sequence":"first","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, Gateshead Health NHS Foundation Trust, Gateshead, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Benjamin Alexander","family":"Marrow","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Gateshead Health NHS Foundation Trust, Gateshead, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dermot","family":"Kearney","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Gateshead Health NHS Foundation Trust, Gateshead, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John William Kenneth","family":"Harrison","sequence":"additional","affiliation":[{"name":"Department of Trauma and Orthopaedic Surgery, Gateshead Health NHS Foundation Trust, Gateshead, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2019,3,12]]},"reference":[{"key":"2025082707395576000_12.3.e227136.1","unstructured":"British Cardiovascular Intervention Society.
