Venoplasty

Venoplasty is a medical procedure used to widen narrowed or blocked veins. It is a type of angioplasty specifically performed on veins. The procedure is typically done using a minimally invasive technique involving a catheter. A thin, flexible tube called a catheter is inserted into a vein, usually in the groin or arm. This catheter is guided under imaging guidance to the site of the venous narrowing. Once in position, a small balloon at the tip of the catheter is inflated. This inflation expands the vein from the inside, pushing back the narrowed walls and restoring a wider passage for blood flow.

Venoplasty is commonly used to treat conditions like chronic cerebrospinal venous insufficiency (CCSVI), a controversial condition associated with multiple sclerosis, and May-Thurner syndrome, where the left iliac vein is compressed by the right iliac artery. It can also be used for other venous obstructions that cause symptoms such as pain, swelling, or fatigue. The procedure is generally considered safe, with potential risks including bleeding, bruising, or re-narrowing of the vein. Recovery is typically quick, with most patients returning to normal activities within a few days. In some cases, a stent may be placed after balloon angioplasty to help keep the vein open.
