Varicose Vein Treatment Dr. Travis Stork: Did you know that bulging blood vessels and varicose veins are some thing that many of you hate like Mariana who recently had a procedure to correct hers. Mariana: I’m only 27 and it seems too young for me to have this problem. My varicose vein starts in the back of my legs and it comes all the way around. Joseph Hewett: Endovenous thermal oblation is really a minimally invasive procedure where we gain access to the varicose vein with a small catheter. We heat the vein up. Its scars close and it goes away. You can see the large black snake appearing things on the screen. Those are varicose veins. This is just to be a very small vein about the size of a hair. And just the overtime, over the years the blood is pulled in this vein and the pressure has caused it to get bigger. If this was left alone, this would just keep progressively worst as you ages. The veins would get bigger and she would get new veins and by that time she is in her 40s or 50s and her leg would have varicose veins all over. That’s the extent of my incision right there. It is about one to two millimeters long. This is a very small needle, we going to use that to get access to the vein. Then a wire goes through the needle into the vein and then we just put sheet over it. So, this is a laser and I’m pressing on a foot pedal underneath the table and its activating the laser. Slowly, pulling back the laser and its heating up the vein and as its heats up the vein, this going to cause that vein to start flowing. So it’s just simple as that and just another medical use of a laser. So, now, we’re going to try and get out the branch. We are not going to use the laser fiber here. We’re just going to use a tiny little hook and get the branch out. I just tug back and fort, I’m just trying to get as much as I can each time.
