Summary
Ultrasound-guided central venous catheter (CVC) placement is safe and effective for apheresis. This minimally invasive technique, using real-time sonography and fluoroscopic confirmation, minimizes complications and ensures successful procedures.
Area of Science:
- Interventional Radiology
- Hematology
- Nephrology
Background:
- Apheresis is crucial for various conditions, but central venous catheter (CVC) placement carries risks.
- Peripheral access is sometimes used due to concerns about CVC complications.
- This study evaluates a specific CVC placement technique for apheresis.
Purpose of the Study:
- To determine the safety and success rate of ultrasound and fluoroscopically guided, non-tunneled dual lumen CVCs for apheresis.
- To assess complications associated with this specific CVC placement method.
- To evaluate the efficacy of real-time sonographic guidance in CVC placement for apheresis.
Main Methods:
- Prospective data collection of 200 attempted CVC placements using real-time sonographic guidance.
- Recording of placement complications, number of passes, and venepuncture success (single pass, anterior wall puncture).
- Documentation of catheterization duration and reasons for removal, including a cohort of stem cell donors.
Main Results:
- 100% successful CVC placement in all 200 patients (191 internal jugular, 7 femoral).
- High success rates: 86.5% single pass, 80.5% anterior wall puncture.
- Minimal complications: 3% inadvertent arterial puncture (clinically insignificant), no other procedure-related issues. 87.4% removed same day.
Conclusions:
- Ultrasound and fluoroscopically guided CVC placement is a safe and successful method for apheresis.
- Real-time sonographic guidance and short catheterization duration are key to minimizing complications.
- This technique offers a viable alternative to peripheral access for apheresis procedures.
