Primary treatment of TRAS with PTA has good intermediate-term results. TRAS is more prevalent in cadaveric allografts with long cold ischemia time.

Multi-detector row CT has an accuracy of 91% in the depiction of suspected acute PE when conventional PA is used as the reference standard.

Both catheters can deliver flow rates well beyond those recommended by the Dialysis Outcomes Quality Initiative. While the Optiflow delivered higher flow rates at some measurement points, this was offset by higher recirculation. The Ash catheter showed a long-term survival advantage and fewer late complications.

Traction removal of smaller-bore silicone catheters is more likely to result in cuff retention than removal of larger silicone and polyurethane catheters, and cuff retention is usually inconsequential.
