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 radiology procedures only require a tiny incision where the catheter is inserted into an artery, so it can result in less blood loss, less pain and a quicker recovery for patients.

Navarro Regional Hospital 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. This vascular procedure 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. Interventional radiologists use catheters 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.

Vertebroplasty with spine jack
Vertebroplasty is used to treat back pain and compression fractures of the spine. Interventional radiologists insert a needle into the affected vertebrae, lift the compression and inject bone cement to stabilize the vertebrae and prevent further damage.
