Study finds DSA-guided TDC outperforms ultrasound-guided TDC in renal replacement therapy.
- Digital subtraction angiography (DSA)-guided tunneled dialysis catheters (TDC) show superior performance compared to ultrasound-guided TDC in renal replacement therapy.
- A retrospective cohort study by Yiwei Shang and colleagues compared ultrasound- and DSA-guided TDC placements in renal replacement therapy.
- Both groups achieved adequate catheter blood flow and ultrafiltration volumes within dialysis prescriptions.
- The DSA-guided group had fewer early dialysis terminations and a more consistent position of the catheter tip in the right atrium.
- The study recommends the use of DSA when the catheter tip cannot be reliably placed in the right atrium.
