Interventional Radiology

---

Minimally invasive interventional radiology techniques are used to treat a wide variety of medical conditions. Radiologists use X-ray and other imaging technologies (MRI, CT and ultrasound) to guide small wires or catheters (thin, flexible tube) 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 results in less blood loss, less pain and a quicker recovery for patients.

Merit Health Central offers a range of minimally invasive interventional radiology techniques to offer safe and effective 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.

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.

Peripherally Inserted Central Catheter (PICC) Placement
Patients with non-healing wounds or recurrent infections may need several weeks of antibiotic therapy. A minimally invasive procedure is used to insert a catheter for IV therapy.

Dialysis and Fistula/Graft Declotting and Interventions
These minimally invasive procedures help improve blood flow for hemodialysis patients. Tunnelled long-term catheters can also be placed for temporary hemodialysis.
