Background

for Thermal Ablation of Great Saphenous Veins

- High ligation and Stripping was a brilliant idea

more than 100 years ago

- Today, numerous prospective randomized trials

comparing thermal ablation to surgery show at

least non-inferiority for procedural success and

clinical results, but improved periprocedural QoL

Advantages (personal selection)

of Thermal Ablation of Great Saphenous Veins

- Totally Outpatient

- No sutures to be removed

- Infections only sporadically reported

- No lymphatic damage in the groin

- Even Coumadin can stay at an INR of 2.0 – 2.5

- Immediate return to normal Life

Thermal Ablation

of Great Saphenous Veins

Ultrasound Technology must be

available during intervention

- 8 to 12 MHz or more Linear Scanner

- Color Duplex and PW-Mode

Thermal Ablation of

Great Saphenous Veins

Catheter and Local Anesthesia Placement Skills

all injections to be performed ultrasound-directed

- Puncture Skills !!!

- placement of catheter or laser fiber at the SFJ not too

ambitious, today 2 cm distance recommended !!

Thermal Ablation of

Great Saphenous Veins

Tumescent Local Anesthesia

Saline with 0.05% Lidocaine

1 mg epinephrine per 1000 cc, 10cc bicarbonate 8.4%

- Pain Control

- Collapsing the GSV around the heat source

- Thermal insulation of the surrounding tissue

Rule #1

for Thermal Ablation of Saphenous Veins

durable success is linked to

sufficient dosing of Heat Energy

to the Vein Wall

Recanalization 12 months after thermal ablation

of the GSV with respect to the administered EFE 940 nm laser – bare fiber

endovenous laser treatment with increased energy dosing: definition of a threshold for

the endovenous fluence equivalent. J Vasc Surg (2006) 44:834-9.

Question #1

for Thermal Ablation of Saphenous veins

How gentle can Heat Energy

be delivered to the Vein Wall ?

Which is the best System ?

future Questions

for thermal Ablation of the Great Saphenous Vein

How does Segmental Ablation compare to

- water absorbed laser wavelengths ?

- Latest laser fiber tip technology ?

There are new concepts arriving:

is the end of the Age of Heat already in sight?

Will we turn to become gluers instead of burners?
