Transcatheter electrocoagulation: experimental evaluation of the anode
Investigative Radiology
|January 1, 1979
Summary
Direct current electrocoagulation is effective for vessel occlusion. However, platinum electrodes, both monopolar and bipolar, frequently caused perforation, and a satisfactory replacement for the stainless steel anode has not yet been found.
Area of Science:
- Biomedical Engineering
- Medical Devices
- Vascular Surgery
Background:
- Transcatheter electrocoagulation is an established technique for achieving vessel occlusion.
- Current limitations exist with the use of stainless steel anodes in this procedure.
Purpose of the Study:
- To evaluate the efficacy and safety of bipolar platinum electrodes for transcatheter electrocoagulation.
- To compare the performance of monopolar platinum electrodes against monopolar stainless steel electrodes.
Main Methods:
- Experimental evaluation of bipolar platinum electrodes.
- Comparative analysis of monopolar platinum and stainless steel electrodes in transcatheter electrocoagulation models.
Main Results:
- Both monopolar and bipolar platinum electrodes demonstrated a high incidence of vessel perforation.
- The unipolar stainless steel anode, despite limitations, remains the current standard without a superior replacement identified.
Conclusions:
- Platinum electrodes are not suitable replacements for stainless steel anodes in direct current electrocoagulation due to perforation risks.
- Further research is needed to develop a safe and effective alternative anode material for transcatheter vessel occlusion.
