Video: Endovenous thermal ablation – Mayo Clinic

Before doing endovenous thermal ablation, the pores and skin and bordering tissues are numbed. The proceduralist can make a compact cut in the pores and skin into which he or she inserts a extremely slender tube identified as a catheter. The catheter is guided into the vein to be handled utilizing ultrasound imaging. The proceduralist applies radiofrequency or laser vitality to the enlarged vein by the catheter’s idea. As the catheter is pulled out, the heat results in the vein to collapse and at some point recover shut. The blood will then reroute by other veins.
