Access is important
• Access is NO. 1 problem
in hemodialysis patient
• The patency of vascular
access is of vital importance
for dialysis patients

Central venous stenosis (CVS)
Varicose Vein
Skin ulcer
CVS Incidence: 8.79% in HD
(From 14 Hospitals in China)
BMJ Open 2015, 5

Etiology of CVS
• Central Venous Cannulation
(temporary / permanent)
Damage the vein
• Rate of Cannulation
62.6% in first hemodialysis
81% waiting for the AVF mature

Etiology of CVS
• High Pressure and flow blood in venous system
–Intimal injury
–Hyperplasia

Conclusions
• CVS is a critical problem for HD
• Endovascular is safe and effective
• Stent+PTA may need in difficult cases
• Restenosis is popular after treatment
• Follow-up is important
• Re-intervention is easy and effective
