Vascular and Interventional Radiology

St. Anthony's vascular and interventional radiology services offer minimally invasive, image-guided diagnostic and therapeutic care for a wide variety of vascular and nonvascular conditions affecting the chest, abdomen and extremities.

Often by making an incision no bigger that the tip of a pen, interventional radiologists treat a wide variety of conditions that once required surgery. Some of the advantages of interventional radiology include:

  • reduced risk, pain and recovery time in many cases
  • many procedures can be performed without an overnight stay in the hospital
  • general anesthesia is not usually required
  • procedures may be less expensive than the surgical alternatives

About the Procedures

In an angioplasty procedure, imaging techniques are used to guide a balloon-tipped catheter, a long, thin plastic tube, into an artery or vein and advance it to where the vessel is narrow or blocked. The balloon is then inflated to open the vessel, deflated and removed. When necessary, a small wire mesh tube called a stent may be permanently placed in the newly opened artery or vein to help it remain open.

Cryoablation is a treatment to kill cancer cells with extreme cold. Cryoablation may be used to treat cancer when surgery isn't an option. Cryoablation is sometimes used as a primary treatment for cancer of the kidney, liver, lung and prostate. Cryoablation is also used to relieve the pain of many different types of cancer that spread to the bone (bone metastasis) or other organs.

Uterine artery embolization is a procedure to treat fibroids without surgery. Using catheters similar to those used to image heart vessels, small particles are injected into the arteries feeding the fibroids. The blood supply of the fibroids is then cut off, causing the fibroids to shrink.

Celiac artery disease, also known as mesenteric ischemia, occurs when blood flow to the bowel or gastrointestinal system (intestines) is decreased because of a blood vessel blockage. Balloon angioplasty or placement of a stent can help resolve painful symptoms.

Vertebroplasty and kyphoplasty are minimally invasive procedures for the treatment of vertebral compression fractures, which are fractures involving the vertebral bodies that make up the spinal column. In vertebroplasty, physicians use image guidance to inject a cement mixture into the fractured bone through a hollow needle. In kyphohplasty, a balloon is first inserted into the fractured bone through the hollow needle to create a cavity or space. The cement is injected into the cavity once the balloon is removed.

Yttrium-90 (Y-90) Treatment: Interventional radiologists at the Heart & Vascular Center at St. Anthony’s use Selective Internal Radiation Therapy (SIRT) to treat inoperable liver cancer tumors. The physicians use yttrium-90 (Y-90) , a radioactive medical device made up of extremely small resin beads. They inject these beads into the main artery that supplies liver tumors. The blood flow delivers the beads to the small blood vessels where they lodge and deliver radioactivity directly to the tumor. This treatment delivers the radiation to the tumor without affecting the nearby healthy liver tissue.
