Catheter Placement

• Interventional radiologists can insert a dialysis catheter (small, flexible tube) used for exchanging blood to and from the hemodialysis machine from the patient.

Vertebroplasty

• This minimally invasive procedure stabilizes a spinal fracture. A biopsy needle is guided into the fractured vertebra under x-ray guidance through a small puncture in the patient’s skin, and specially formulated acrylic bone cement is injected into the fractured vertebra to stabilize the vertebral bone.

Kyphoplasty

• This procedure is designed to stop the pain caused by a spinal fracture, to stabilize the bone, and to restore lost vertebral body height due to a compression fracture. Using image-guided techniques, a catheter (long, thin tube) is guided to the correct position through a small incision made in the back. The catheter creates a path through the back into the fractured area for treatment.

Diagnostic Angiograms

• In this procedure, a catheter (long, thin tube) will be inserted in your leg or arm and the radiologist will flush a dye through the arteries to check blood flow and locate blockages or narrowed vessels.

Carotid Stenting

• Carotid angioplasty is a minimally invasive procedure performed after the diagnostic angiogram. During angioplasty, a balloon catheter (long, thin tube) is guided to the area of the blockage or narrowing. When the balloon is inflated, blood flow improves. A carotid stent (a small, metal mesh tube) is placed inside the carotid artery at the site of the blockage and provides support to keep the artery open.

Cerebral Aneursym Coiling

• This is a minimally invasive treatment for aneurysms and other blood vessel malformations called fistulas that occur in the brain. A catheter (long, thin tube) is inserted through the skin into an artery and, using image-guidance, is maneuvered through the body to the aneurysm or fistula. Then, one or more coils are inserted through the catheter and placed at the target site, where it is anchored. Blood clots around the coil(s), which helps block the flow of blood into the bulge or passageway and keep the vessel from rupturing or leaking.

Arteriovenous Malformation (AVM) Embolizations

• This interventional neuoradiological procedure involves the insertion of a catheter (long, thin tube) through an artery in the groin. The tube is guided up through the blood vessels to the site of the AVM (an abnormal collection or tangle of vessels where arteries are interconnected with veins), where it delivers a liquid similar to glue that clogs up the malformation to restore normal circulation.

Tumor Embolizations

• Tumor embolization is designed to reduce or block the blood supply to a tumor by injecting a blocking agent (an embolic) through a catheter (long, thin tube) into a blood vessel, blocking the blood that feeds the tumor. Blocking the blood supply to the tumor is intended to result in shrinking or death of the tumor.

Mechanical Thrombectomy for Acute Stroke

• One intervention for an acute stroke is the mechanical removal of the blot clot. This is accomplished by inserting a catheter (long, thin tube) into the femoral artery (in thigh), directing it to blood vessels supplying blood to the brain, and deploying a corkscrew-like device to ensnare the clot, which is then withdrawn from the body.

Catheter Directed Thrombolysis for Acute Stroke

• Using image guidance, this procedure embeds a catheter (small, flexible tube) directly into a venous blood clot to treat an acute stroke.
