Angiography > Exams & Procedures > Subclavian Vein Angioplasty
This procedure is performed to dilate a narrowing in the subclavian vein (in the upper chest region). It is a venous study. Local anaesthetic is given to numb the area and then venous access is obtained, usually from the femoral vein (groin region). A small thin tube, commonly called a catheter, is advanced as close to the stenosis (narrowing) as possible. The narrowing is then gone through with a tiny wire and angioplasty (ballooning) of the vessel is then performed with a balloon catheter. The radiologist will review the pictures and then decide if further treatment is necessary. Once the radiologist is finished, he/she will apply pressure to the puncture site.
This procedure takes about one hour. You will be on bed rest for a couple of hours after the procedure.
