How does it work?
During intravenous thrombolysis, an interventional radiologist injects contrast material into an artery in the groin, wrist, or elbow. Patients are usually kept awake during the procedure and given a mild sedative to relieve any discomfort.
With the help of X-rays and contrast dye, the physician is able to map the precise location of the clot and uses catheter (thin, flexible tube) to inject the drugs into the blood vessel or at the site of the clot. The physician monitors the clot via X-ray until it successfully dissolves.
