Dr. Agrawal, Dr. Dymek, and Dr. Banker, the trio of vascular and interventional radiologists at Vein Experts, LLC, keep troublesome vessels in check with a menu of outpatient treatments. They tame mild cases of spider veins with medical-grade compression stockings, lasers, and sclerotherapy. More serious varicose veins that rise above the skin crumble like mined mountaintops after the VNUS Closure catheter blasts them with radio-frequency energy.
