Angioplasty
This procedure may be used to widen the affected vein and improve blood flow after the blood clot has been dissolved. Narrowing (stenosis) of the vein can block blood flow and make it more likely for a blood clot to form. A catheter with a balloon on the end is inserted into the affected vein. X-rays are used to position the catheter. Once the catheter is in place, the balloon is inflated to widen your vein. In some cases, a wire mesh device, called a stent, may also be placed in your vein to help keep it open.
