Inventional Radiology Procedures
Interventional radiologists are able to perform minimally-invasive treatments for a variety of conditions. Some are diagnostic in nature, and others even give hope for those with inoperable tumors. Some procedures are detailed:
Y-90 Treatment for Liver Tumors
Where surgery is not possible to remove liver tumors, the Y-90, Yttrium-90 Microspheres (Y-90), treatment may give you an improved quality of life. This minimally invasive procedure uses Selective Internal Radiation Therapy (SIRT) to deliver targeted, micro-particles, called SRI-spheres. This procedure provides internal radiation therapy directly to the tumor.
SIR-Spheres microspheres are microscopic polymer beads that contain the radioactive element yttrium-90 (Y90) and emit beta radiation to kill cancer cells. Due to their small size, they travel easily through the bloodstream directly to the liver. The microspheres become lodged in the small blood vessels supplying the tumor and kill the cancer cells.
SIR-Spheres microspheres and SIRT are considered a safer and more effective method of using radiation to treat liver cancer and are often used in conjunction with chemotherapy.
Peripheral vascular disease (PVD) can occur when a disease or disorder causes a reduction in blood flow to any part of the circulatory system - outside of the brain or heart. Frequently caused by fatty deposits in arteries, or artheroschlerosis, this is one of the leading causes of disability in adults over 50.
Interventional radiologists can frequently diagnose PVD using non-invasive imaging such as doppler ultrasound or CT imaging. If a diagnosis cannot be made, we may recommend conventional arteriography. This procedure involves insertion of a catheter and imaging medium through an artery. This procedure is done in an operating room under anesthesia. If a blockage is diagnosed, we may recommend and continue on to perform angioplasty - using special tools to break up blockage within the artery affected.
Renal angiography (X-ray of the arteries supplying blood to the kidneys) is performed for patients with elevated blood pressure or impaired kidney function suspected of being due to blockage of the arteries supplying the kidneys. Prior to this procedure, we develop a specific treatment plan using the results of CT or MR angiograms.
If blockage is found, the interventional radiologist may continue with angioplasty and placement of a stent to open the artery.
Uterine fibroid embolization (UFE) is an alternative to hysterectomy and is performed for women who have lifestyle limiting symptoms due to uterine fibroids. This procedure is performed in an operating room under anesthesia and may require an overnight stay in the hospital. Using a catheter inserted into the affected arteries, blood supply to the fibroids is then cut off.
Vertebroplasty is performed for patients with intractable pain due to compression fractures of the spine. The pain must be lifestyle limiting or require regular narcotic pain control. The pain often keeps patients awake at night.
The goal of vertebroplasty is to eliminate pain or decrease it to a tolerable level and to restore ability to perform activities of daily living. Fractures from the upper thoracic spine to the lower lumbar spine and sacrum can be treated. Patients must not have clinical signs of compression of the nerves or spinal cord related to the compression fracture. Under anesthesia, an artificial cement is injected into the affected area.
