VELAS Endovenous Laser Treatment for the Saphenous Vein

Endovenous Laser Treatment for the Saphenous Vein

Clinical Application:
Endovenous Laser Treatment for the Saphenous Vein from GIGAALASER

Clinic Explanation:
GSV, also long saphenous vein, is the larger superficial vein of the leg and thigh. Varicose
vein is because the lower limb's venous valve damaged, and then the blood reflux and
haemostasis occurred. In that case, the superficial vein pressure increased, the vein will
stand out the surface. So, the GSV happened. Genetic brings the GSV. The long-time
standing, especially heavy manual labor is also the couses of GSV.

EVLT; EVLA; saphenous veins

Medical device:
Velas30w 980nm (operation power 10-15w), pulse

Accessories:
600um optical fiber; 18G needle; 0.035-inch guide wire; 5Fcatheter

Operation procedure:
1. According to the diagnostic results to make sure and map the correctly operation position.
2. Open the device and connect fiber, set up 10w power. Pulse duration.
3. Anaesthesia.
4. Great saphenous vein (GSV) cannulated ankle level or below knee via a needle puncture. A guide wire passed into the saphenofemoral junction (SFJ); a catgeter was placed over the guide wire.
5. Withdraw the guide wire and replaced to 600um optical fiber; the diatal tip of the laser fiber was positioned at 1-2cm below the SFJ with the guidance of the red aiming beem.
6. Wearing a laser safety goggle, lower down the light. Focused on the red aiming beam withdraw the fiber and catheter slowly in 2-3mm/s as laser energy. The assistor manually pressured GSV with chilled water gauze and removed along the laser fiber
tip at the same time.

7. If contort GSV or varicose vein into the group which couldn't let fiber passed through, needed punctured separated.
8. At the end of the procedure, compression was applied with a compression bandage for the first 24h, and subsequently, a thigh length medical compression stocking was worn for 3 weeks.
9. Patients were instructed to walk immediately. But avoid taking hot shower and strenuous exercise.
10. After operation follow-up.

Advantage:
1. No deep venous, dyschromia, superficial burns, thrombophlebitis, papable indurations.
2. Very safe especially the energy applied is calculated as a function of the GSV diameter. Less complication and bleeding.
3. Not too much or even no anesthetic, painless.
4. The proper tumescent anesthetic solution provides a margin of safety to avoid the heat damage.
5. The size of the vein access needle is truly minimal procedure that leaves a nearly invisible scar on the skin.
6. Closure rate at the 1-month follow-up is nearly 100%.

Notice:
1. Patient  should be placed in the Trendelenburg position for treatment to reduce the amount of blood inside the vein.

2. LEED was turned as SSV and GSV diameter measured in upright position.
3. Adjust pulse duration for each individual GSV segment from 1.2 seconds(2mm) up to 6 seconds(10mm)
