Does Minimal Post-operative Compression Affect the Outcome for Endovenous Ablation in Treating Varicose Vein Patients?
In this proposal, the investigators seek to determine whether a reduced compression after endovenous ablation procedure in treating superficial venous insufficiency affects the outcomes. This study involves only the use of the compression stocking post endovenous ablation procedure and everything else is standard according to current guidelines.
The investigators general strategy will be to determine the role of a minimal post-operative compression and the status of patient satisfaction including (1) Success closure rate of the treated vein. (2) Less pain; (3) Easier accepted by the patients.

Detailed Description
All adults with varicose vein who are here in the investigators clinic to seek for endovenous ablation treatments will be invited to participate in this study. The participation in this research is entirely voluntary.
A. Each patient is given a code number instead of ID(identification) in the chart. Eligible patients according to their vein size are divided into following groups using a computer-generated randomization list:
- Vein diameter between 5.5 and 6.7 mm, Post-op compression 1 day;
- Vein diameter between 5.5 and 6.7 mm, Post-op compression 7 days;
- Vein diameter between 6.8 and 8.5 mm, Post-op compression 3 days;
- Vein diameter between 6.8 and 8.5 mm, Post-op compression 7 days.
B. Researchers: Data collectors and ultrasound technicians are blinded to the type of intervention, using code instead of patient's ID. The operating surgeon will not be the one who collects data. Performing physicians master these endovenous procedure techniques equally, have performed a minimum of 20 procedures independently.
C. Device: Graduated medical compression hosiery, 15-20mmHg. BrightLife Direct, Washington, DC. Endovenous ablation device: 1. Radiofrequency Ablation- FDA approval 1999, VNUS RFG2, San Jose, CA; 2. Endovenous Laser ablation- FDA approval Jan 2002, TVS 1470 by Total Vein System. Wavelength 1470nm, Nano Laser System device, Houston, TX. These two procedures are standard care under current guideline.
D. The research takes place over 12 months in total. During that time, it will be necessary for each patient to come to the clinic 6 times, for 1 hour each. The investigators would like to meet with every patient 1 week and 1, 3, 6, 12 months after the procedure respectively for a check-up.
