Vascular calcification is common among hemodialysis patients. In this report, we presented a case of superior vena cava (SVC) stent migration during endovascular angioplasty in a 50-year-old female hemodialysis patient with severe SVC calcification. The stent migration was refractory to the deployment of a second anchor stent, which shortly resulted in pericardium tamponade and was successfully rescued by emergent thoracotomy. The potential role of vascular calcification as a risk factor to stent migration was discussed. Patients with severe vascular calcification receiving endovascular angioplasty might need a careful risk screening for stent migration.
