INTERVENTIONAL RADIOLOGY

Interventional Radiology is the medical super speciality where specially trained physicians offer minimally invasive & precisely targeted treatments. Interventional Radiologist use radiological image guidance - X-ray fluoroscopy, ultrasound or CT scans to advance a tiny catheter in the body to precisely treat the disease internally. Today many conditions that once required surgery can be treated by this minimally invasive modern medicinal approach. Interventional radiology treatments offer less risk, less pain and less recovery time and early return to work compared to open surgery. As many IR procedures start with passing a needle through the skin to the target it is sometimes called pinhole surgery! The range of conditions which can be treated by IR is enormous and continually expanding. It is important to recognise that the interventional treatment is usually one of several treatment options available ranging from nothing, through drug treatment and up to surgery. A glossary of common interventional techniques is below Angiography - An X-ray exam of the arteries and veins to diagnose blockages and other blood vessel problems; uses a catheter to enter the blood vessel and a contrast agent (X-ray dye) to make the artery or vein visible on the X-ray. Angioplasty - Opens blocked or narrowed blood vessels by inserting a very small balloon into the vessel and inflating it or placement of the metallic stent. Used by IRs to unblock clogged arteries in the legs or arms (called peripheral arterial disease or PAD), kidneys, brain or elsewhere in the body. Biliary drainage (PTBD) & stenting - Uses a stent (small mesh tube) to open up blocked ducts and allow bile to drain from the liver. DVT thrombolysis- the injection of blood clot dissolving medicines (thrombolysis) through a small catheter passed into the vein. Gastrointestinal bleeding Embolisation - Interventional radiologists can pinpoint the area of internal bleeding with angiography and inject a clotting substance, such as a gel, foam or tiny coils, through a thin catheter to stop the bleeding. Chemoembolisation for liver tumors- Delivery of cancer-fighting agents directly to the site of a cancer tumor thus limiting some of the side effects of cancer therapy & leading to improved survival with reduced morbidity. Radiofrequency ablation- Use of tiny radiofrequency needle to \\\"cook\\\" and kill cancerous tumors in Liver, lung, kidney or bones. Uterine Artery Embolisation- An embolization procedure of uterine arteries to stop life-threatening postpartum bleeding, potentially preventing hysterectomy. The same procedure is used to treat fibroid tumors and is then called UFE (Uterine Fibroid Embolization). Varicose veins Ablation- The saphenous vein is sealed shut through the use of a laser or radio frequency non-surgically. IVC filter insertion- A tiny cage-like device that is inserted in a blood vessel to break up clots and prevent them from reaching the heart or lungs. Prevents pulmonary embolism.
