Why the study?
Can angiogram identify the cause of unexplained prolonged exit site bleeding from tunneled dialysis catheters?
Can angiogram identify the cause of unexplained prolonged exit site bleeding from tunneled dialysis catheters?
Angiogram is a useful diagnostic tool for identifying unsuspected catheter leaks in patients presenting with prolonged exit site bleeding after tunneled dialysis catheter placement.
May aid diagnosis of occult catheter leaks in exit-site bleeding; hypothesis-generating and requires prospective validation before routine use.
Bleeding after hemodialysis catheter placement is commonly seen and can happen because of anticoagulation, poor platelet function in dialysis patients, and trauma to the vessel and tunnel tract during placement. We wish to present here two cases of prolonged exist site bleeding with tunneled dialysis catheters (SchonCath dialysis catheter, Angio-Dynamics, Queensbury, N.Y.) due to unsuspected catheter leak within the tunneled portion of the catheter, which was identified with angiogram.
