Abstract: Due to the unique anatomic characteristics of superior vena cava and adjacent veins, superior vena cava syndrome (SVCS) was mainly reported in malignancies in earlier cases and studies. With the development of central venous catheter (CVC) indwelling technique for hemodialysis and the concerning
about the prognosis and longer vascular access in hemodialysis patients, CVC-induced SVCS has been emphasized in clinical practice. Therefore, it is clinically significant to clarify the prevalence, mechanism, early imaging diagnosis and management strategy of SVCS in hemodialysis patients using CVC for vascular
access.

Key words: hemodialysis, central venous catheterization, superior vena cava syndrome
