Video: Endovenous thermal ablation – Mayo Clinic

Just before accomplishing endovenous thermal ablation, the pores and skin and surrounding tissues are numbed. The proceduralist would make a compact reduce in the pores and skin into which he or she inserts a very thin tube referred to as a catheter. The catheter is guided into the vein to be dealt with applying ultrasound imaging. The proceduralist applies radiofrequency or laser power to the enlarged vein via the catheter’s idea. As the catheter is pulled out, the warmth brings about the vein to collapse and ultimately mend shut. The blood will then reroute via other veins.
