Video: Endovenous thermal ablation – Mayo Clinic

Just before executing endovenous thermal ablation, the pores and skin and encompassing tissues are numbed. The proceduralist makes a compact lower in the pores and skin into which he or she inserts a extremely thin tube called a catheter. The catheter is guided into the vein to be addressed working with ultrasound imaging. The proceduralist applies radiofrequency or laser vitality to the enlarged vein by the catheter’s tip. As the catheter is pulled out, the warmth triggers the vein to collapse and sooner or later heal shut. The blood will then reroute by means of other veins.
