Stenosis of Arteriovenous Dialysis Fistula Clinical Trial
Official title:
Effect of Temporary vs.Long Term Hemodialysis Catheter on Central Vein Stenosis in Long-term Hemodialysis Patients
Vascular access (VA) is the most important for carrying out hemodialysis, yet it may bring in complications and leads to hemodialysis quality decline. This study aimed to explore the impact of vascular access types, including temporary vs.long term hemodialysis catheter on central vein stenosis.
It is unknown whether central vein stenosis occurs after temporary or long term hemodialysis catheter in long-term hemodialysis patients. this study will aim to explore this question. Study design is randomized, controlled trial. One arm is temporary catheters in the internal jugular vein, and another arm is tunneled cuffed hemodialysis cather. 2*2 is randomly distributed. The main outcome: central vein stenosis diagnosed by venography. The secondary outcome: the time of infection, and catheter patency. Study period: one year ;
