Video: Endovenous thermal ablation – Mayo Clinic

In advance of doing endovenous thermal ablation, the skin and bordering tissues are numbed. The proceduralist will make a compact cut in the skin into which he or she inserts a pretty skinny tube called a catheter. The catheter is guided into the vein to be dealt with using ultrasound imaging. The proceduralist applies radiofrequency or laser strength to the enlarged vein as a result of the catheter’s suggestion. As the catheter is pulled out, the warmth leads to the vein to collapse and at some point heal shut. The blood will then reroute as a result of other veins.
