Video: Endovenous thermal ablation – Mayo Clinic

Prior to executing endovenous thermal ablation, the pores and skin and surrounding tissues are numbed. The proceduralist makes a compact reduce in the pores and skin into which he or she inserts a really slim tube called a catheter. The catheter is guided into the vein to be dealt with utilizing ultrasound imaging. The proceduralist applies radiofrequency or laser power to the enlarged vein by means of the catheter’s tip. As the catheter is pulled out, the heat results in the vein to collapse and sooner or later recover shut. The blood will then reroute by means of other veins.
