RT Journal Article SR Electronic T1 Infected chronic sinus secondary to a retained fragment of radial artery introducer sheath following percutaneous coronary intervention (PCI) JF BMJ Case Reports JO BMJ Case Reports FD BMJ Publishing Group Ltd SP e227136 DO 10.1136/bcr-2018-227136 VO 12 IS 3 A1 Ghazala, Christopher George A1 Marrow, Benjamin Alexander A1 Kearney, Dermot A1 Harrison, John William Kenneth YR 2019 UL http://casereports.bmj.com/content/12/3/e227136.abstract AB Coronary angiography and percutaneous coronary intervention (PCI) are frequently performed procedures in the UK and the developed world, with the radial artery becoming the preferred route of access. 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.
