Before the treatment, you will be seen in the clinic by your interventional radiologist for a clinical assessment, which includes checking medical history, drug allergies, blood tests (blood count, liver and kidney function, clotting times). If you are on certain blood-thinning medications, they may need to be stopped a few days before the procedure. You will receive specific instructions on how to prepare, such as fasting 4 to 6 hours before the time of the planned procedure. You should plan to stay overnight at the hospital for one or two days after the procedure for monitoring.
