Vascular Stent Migration to Right Ventricle

Abstract

https://e-kcj.org A 62-year-old woman with diabetes mellitus, hypertrophic cardiomyopathy, and end-stage renal disease was undergoing chronic hemodialysis via a right radio-cephalic arteriovenous graft. She required hospitalization due to fever, dyspnea, and right shoulder pain. One year earlier, she had undergone balloon angioplasty, followed by deployment of an axillary vein stent (6×80 mm) due to central stenosis. Upon admission, computed tomography revealed right shoulder and psoas muscle abscesses and a pulmonary thromboembolism. Coincidently, during the work-up, a metallic foreign body was detected in the right ventricle (RV), suggestive of a migrated vascular stent (Figure 1A-C). Transthoracic echocardiography revealed a migrated vascular stent in the RV cavity, impacted between the tricuspid valve (TV) septal leaflet and the RV apex (Figure 1D). After antibiotic treatment of the abscesses, the stent was successfully removed, without TV or RV injury, through the right atrium (Figure 2A and B).
