Angiography is performed to evaluate the blood vasculature utilizing specialized pediatric catheters and technique. These examinations are performed with digital and/or biplane conventional film techniques. Intravascular interventional procedures including angioplasty and vascular ablation with sclerosing agents are performed. CT and Ultrasound guidance of percutaneous catheter placement and biopsy are also routinely performed, often obviating the need for more invasive general surgery. These complex studies are usually arranged in advance by your physician and, in many cases, require admission to the hospital. Your physician will advise you of the preparation for the examination.
