Gedetailleerde beschrijving
The endovenous treatment of the insufficient saphenous vein (large saphenous vein and small saphenous vein) is a standard procedure for years. There are different methods that cause an obliteration of the vein using heat. The adventage of these methods are low rates of minor and major complications compared to classic open surgery. There are also advantages concerning cosmetic and recurrence of varicous veins. Actually there are two different methods for the endovenous obliteration of the saphenous vein - lasers with wavelength of 1470nm or 1320nm and the radiofrequency method. The objective of this study is to compare these two different methods concerning postoperative pain, obliteration rate and the rate of pleased patients in 140 patients. All patients get an venous ultrasound investigation to determine the stadium of venous insufficiency. There are consecutive ultrasound investigations 10 days, 3 months and 12 months after surgical treatment.
In this study there are no additional risk factors for the included study patients except the risk of surgery.

Obliteration of the treated vein (GSV or SSV)
Tijdsspanne: day 10, month 3, month 12
|
An ultrasound investigation of he treated vein is done to find out if the treated vein is fully obliterated or not.
If it is not fully obliterated we want to find out if there is any pathological reflux in the vein.
|
day 10, month 3, month 12

Patient´s satisfaction after the intervention
Tijdsspanne: day 10, month 3, month 12
|
The patient is asked about his/her satisfaction after intervention.
This is measured on a numeric scale from 1 to 5 (like schoolmarks in austria or germany).
1=very good, 2=good, 3=average, 4=not so good, 5=bad)
