CTICasesRVAD Cannula Tourniquet Radiopaque Markers
Imaging findings
Chest radiograph and CT show radiopaque, hollow tubular metal markers (tourniquets) anchored near the anterior chest wall and skin, used to fix the right atrial and pulmonary artery cannulas of an extracorporeal right ventricular assist device (RVAD) in place.
Key takeaways
Following LVAD placement, right ventricular failure may require temporary RVAD support. Radiopaque tourniquets are utilized by surgeons to secure these large-caliber cannulas to the chest wall. Recognizing these devices on post-operative imaging is important to prevent misinterpreting them as retained foreign bodies or other surgical complications.
