Right atrial ball thrombus as a complication of subclavian catheter insertion for hemodialysis access
The International Journal of Artificial Organs
|March 1, 1987
Insights
Prolonged subclavian catheter use for hemodialysis can cause right atrial ball thrombi due to catheter friction. Preventing this complication involves ensuring catheters do not reach the right atrium.
Area of Science:
- Cardiology
- Nephrology
- Medical Devices
Background:
- Subclavian cannulation is a common procedure for long-term hemodialysis access.
- Catheter-related complications can arise from prolonged use and improper placement.
- Right atrial thrombi are a rare but serious potential complication.
Abstract:
In two patients right atrial ball thrombi developed following prolonged subclavian cannulation for hemodialysis. One patient died, the other had the ball thrombus removed by open heart surgery. It appears that repeated friction of the catheter tip may have damaged the endothelium of the right atrial wall. This hitherto unrecognised complication might be prevented by ensuring that subclavian hemodialysis catheters are never allowed to reach as far as the right atrium.
