Interventional Radiology
Minimally invasive interventional radiology techniques are used to treat a wide variety of medical conditions. Radiologists and other specialists use X-ray and other imaging technologies (MRI, CT and ultrasound) to guide small wires or catheters (thin, flexible tubes) with specialized instruments to treat affected areas of the body. These procedures only require a tiny incision where the catheter is inserted into an artery, so it often results in less blood loss, less pain and a quicker recovery for patients.
Northwest Health offers a range of minimally invasive interventional radiology techniques to offer options to treat a variety of conditions, including:
Angiography and Angioplasty
A diagnostic angiogram is used to examine the inside of arteries and veins to detect blockages or narrowing of the vessels. In angioplasty, a catheter fitted with a balloon device is guided to the affected area to expand the walls and restore blood flow, or a laser can be used to break up the blockage. In some cases, a stent (mesh tube) is placed in the artery to hold it open. Angioplasty can be used to treat everything from heart disease and circulatory problems to ischemic stroke.
Embolization
Embolization is used to stop abnormal bleeding or to cut off blood supply to a particular area, such as a tumor. Catheters are used to deliver blood-clotting medication, or to place particles or coils in the vessels to stop blood flow. Embolization can provide a life-saving treatment for hemorrhagic stroke and trauma patients, and can serve as an effective treatment for fibroids.
Radiofrequency Ablation
Ablation is used to destroy abnormal cells with a catheter fitted with a tiny electrode. It can be used to treat everything from varicose veins and chronic pain to heart arrhythmias and cancer.
Transjugular intrahepatic portosystemic shunt (TIPS)
Transjugular intrahepatic portosystemic shunt (TIPS) is a procedure that may be used to reduce portal hypertension and its complications, especially variceal bleeding. A TIPS procedure may be done by a radiologist, who places a small wire-mesh coil (stent) into a liver vein.
Vertebroplasty
Vertebroplasty is used to treat back pain and compression fractures of the spine. Doctors insert a needle into the affected vertebrae and inject bone cement to stabilize the vertebrae and prevent further damage.
