Here's a look at some of the vein treatment options offered at the BASS Vein Center
Vein Treatment

Conservative Vein Treatment

Given that varicose veins are not a life- threatening problem, some patients achieve adequate relief with conservative therapy. This includes leg elevation and the use of compression stockings for symptom relief.Some insurance companies require a trial of compression stockings for 6-12 weeks prior to approval for a more definitive treatment.

Radiofrequency Ablation Therapy

Radiofrequency ablation therapy uses precision focused radio-frequency energy to treat varicose veins. During the procedure, a small catheter is inserted into the vein. The catheter is heated using radio-frequency energy. The heat from the catheter shrinks and collapses the diseased vein, effectively sealing off the malfunctioning portion of the vein.
