Conservative therapy for chronic venous disease has several components. If there is a history of deep vein thrombosis, blood thinners are often necessary as they prevent more clots from forming. Compression stockings can relieve symptoms and improve quality of life. Active wound management may be necessary for patients with ulcers.
When conservative methods alone are not effective in managing chronic venous disease, minimally invasive catheter-based procedures can improve symptoms in select patients. One catheter-based procedure “recanalizes”, or opens up chronically occluded veins through a combination of balloon angioplasty and stents. Another procedure eliminates refluxing superficial veins.
