简要总结
Randomized two-arm study examining 90 day primary patency of two FDA-approved tunneled dialysis catheters.
详细描述
The VectorFlow tunneled dialysis catheter is a novel symmetrical tip design tunneled dialysis catheter which in pre-clinical testing and retrospective review has improved flow and patency compared to other dialysis catheter designs. This study will compare 90 day patency rates of newly inserted VF catheters to the Palindrome catheter both of which are FDA approved devices and will inserted as standard of care. The Palindrome catheter has been selected as the comparison device because it is also a symmetrical tip catheter design and prior studies by the manufacturer of this device suggests it has a lower occlusion rate and better flow compared to other catheter designs.

研究组 & 干预措施
Palindrome TDC
TDC insertion with Palindrome will be in accordance with its FDA-approved indication under moderate sedation or general anesthesia with local anesthesia using 1% lidocaine in per institutional protocol. Following TDC insertion, the catheter may be used immediately. The goal of HD is typically to achieve a target effective blood flow of 300mL/min within the first 3 hemodialysis sessions. The dialysis records from each of the first three HD sessions will be reviewed by the study coordinator for (A) Blood flow rate (QB), (B) Arterial and venous lumen pressures, (C) Kt/V, and (D) Urea reduction ratio (URR). Additionally, need and use of thrombolytic infusion (ie t-PA) (other than single dose injection) to restore or improve patency and/or need for catheter exchange.

结局指标
主要结局
Primary Patency - Intervention-free Interval (Measured in Weeks)
时间窗: 30, 60 and 90 days
The primary study endpoint will be primary patency at 90 days following catheter insertion. Primary patency is defined as an HD catheter which provides adequate hemodialysis (flow \>300mL/min) without need for additional interventions (ie TPA infusions or catheter exchange) to maintain flow or correct device failure.
