What Is Interventional Radiology? How It Can Help You
Interventional radiology is a rapidly developing field which uses minimally invasive techniques to perform various procedures such as angioplasty or stenting (insertion of small metal tubes) to unclog blocked arteries. Advanced imaging techniques including ultrasound, computed tomography, fluoroscopy or MRI are used to guide wires, needles and catheters to the desired location and then perform the procedure without requiring a large open incision. These techniques can be used to perform procedures such as radiofrequency ablation where a special needle is inserted into a tumor and heat delivered to destroy and treat the tumor. Similar principles allow advancement of a catheter into the vessels feeding uterine fibroids. Through this catheter, particles can be injected to deprive the fibroid of its blood supply thereby causing them to shrink and alleviate the symptoms. In the emergency setting, acutely bleeding vessels can be treated in the same manner.

Opening Blockages and Narrowings of Arteries
and Blood Vessels

When blockages or narrowings affect the arteries and there is insufficient blood flow to the leg or foot claudication (excerise induced cramping, pain or tiredness in the leg) can result. Special balloon catheters can be advanced to the site of narrowing and the balloon dilated to increase the diameter of the vessel and increase the amount of blood flow. Vessels that go to the brain will be able to be treated in a similar fashion (carotid angioplasty). By opening the vessels, the chance of stroke can be decreased. Vessels to the kidneys can become narrowed and cause renal failure or hypertension. Angioplasty or stents can be used to open up the vessels and reduce the symptoms or progression of the renal failure. In conjunction with our surgical colleagues, large stent grafts can be delivered into the body through small incisions in the groin vessels to treat abdominal aortic aneurysms. Aneurysms are weaknesses in the blood vessel wall and can rupture over time. The stent graft (metal tube covered in fabric) removes the pressure from the wall of the blood vessel and lessens the chance of the vessel rupturing.

Relieving Pain From Spinal Compression Fractures
Compression fractures of the spine (collapse of the vertebral body) can cause severe pain. Using x-ray guidance, needles can be advanced into the collapsed vertebral body and special materials can be injected to reinforce the bone and lessen the pain by preventing further collapse and allowing the bone to heal itself. In many cases this vertebroplasty procedure can have dramatic results.

Treating Patients With Liver Damage

In patients with damage to the liver, they can develop blockage to blood flow in the liver. The blood then backs up and creates varices which can rupture and cause severe bleeding. Using interventional techniques, a stent (flexible metal tube) can be inserted through the vein into the liver. This new channel then allows the blood to bypass the damaged liver and prevents the varices from rupturing.
