Interventional radiology services

Our interventional radiology (IR) physicians offer a comprehensive program of minimally-invasive diagnostic and therapeutic procedures to treat a wide variety of disorders. Listed below are common medical conditions that interventional radiology techniques can treat and manage. 

Uterine fibroids

Varicose/spider veins

  • Endovenous laser ablation (EVLT) - Treatment for saphenous vein reflux
  • Ambulatory (micro) phlebectomy - Removal of bulging surface varicose veins
  • Sclerotherapy – Injections for spider veins

Back pain

  • Kyphoplasty – Treatment for acute (non-healed) painful vertebral body compression fractures
  • Epidural steroid injections – Injections for back pain relief
  • Facet (medial branch) blocks – Injections for back pain relief
  • Radiofrequency (RF) medial branch denervation – Treatment for chronic facetogenic back pain
  • Sacro-iliac (SI) joint injections – Treatment for SI (buttock) pain
  • Selective Nerve Blocks (SNRB) – Treatment for radicular (arm or leg) nerve pain
  • Discograms - Evaluation of suspected discogenic pain

Central venous access

IRs can assist with placing central venous access catheters (CVAC) and ports beneath the skin and into the blood vessels so patients can receive medication or nutrients directly into the blood stream or so blood can be drawn.

  • Chest ports (placement and removal)
  • Hickman catheters (placement and removal)
  • PICC lines (placement, exchange, repositioning)

Enteral access (nutrition, drainage)

Using x-ray guidance, IRs can place feeding tubes directly into the stomach and/or small intestine for patients who cannot obtain nutrition by mouth.

  • Gastrostomy/gastric tubes (placement, exchange)
  • Gastrojejunostomy (GJ) tubes (placement, exchange)

Cancer

  • Radiofrequency (RF) ablations – Lung, liver, kidney, adrenal tumors
  • Radioembolization – TheraSphere® liver cancer treatment with Y-90

Peripheral vascular disease

Interventional radiologists are vascular disease experts. They can perform x-rays of arteries and veins to diagnose blockages and other blood vessel problems as well as fix blocks and narrowing in arteries and veins to restore blood flow.

  • Angiography, CO2 angiography - X-ray of arteries and veins to visualize blood vessels
  • Angioplasty - Procedure to open blocked blood vessels. In balloon angioplasty, a small balloon is threaded by catheter into the artery and inflated to keep it open.
  • Stenting - A stent (metal scaffold) is used to keep a blood vessel open.
  • Thrombolysis - When blockage in an artery is caused by a blood clot, thrombolytic drugs are injected through a catheter to dissolve the clot.

Deep vein thrombosis (DVT)

DVT is a serious condition that occurs when blood clots form in the deep leg vein. It can lead to post-thrombotic syndrome, or a life-threatening pulmonary embolism. Interventional radiologists perform catheter thrombolysis, a "clot-busting" treatment, to restore blood flow.

  • Central (axillosubclavian, iliofemoral, caval DVT) – Catheter directed thrombolysis/stenting
  • IVC filter (placement, filter removal)

Liver disease (portal hypertension)

Portal hypertension (high blood pressure) occurs when normal blood flow in veins to the liver is blocked or slowed. It is commonly seen in patients with liver disease due to cirrhosis or hepatitis. This condition can cause internal bleeding and be life-threatening. Interventional radiologists can treat portal hypertension and related conditions, including variceal hemorrhage and refractory ascites.

Hernia

  • Herniography - Abdominal wall hernia evaluation

Renal disease/failure (dialysis access management)

Interventional radiologists can diagnose renovascular disease using imaging techniques. They can treat renal hypertension (high blood pressure in the kidneys) with angioplasty to restore normal blood flow to the kidneys. For patients with kidney failure who require dialysis, IRs can provide non-surgical management of dialysis clots. A fistula is a surgical "connection" used to join a vein and artery in the forearm to allow access for dialysis.

  • Dialysis shunt/fistula – Evaluation, angioplasty, stenting, declots
  • PermCath™ (placement, exchange, removal)
  • Temporary dialysis catheters (placement, exchange)

Bleeding, aneurysms, AVM

Arteriovenous malformation (AVM) is an abnormal connection between arteries and veins that can cause serious bleeding and intense pain.

  • GI (stomach, bowel, liver, spleen, pancreas) – Mesenteric angiography, embolization
  • Epistaxis (nosebleeds) – Cerebral angiography, embolization
  • Hemoptysis (coughing up blood) – Bronchial angiography, embolization
  • Trauma/Tumors – Angiography, embolization
  • AVMs (pulmonary, renal, etc.) – Angiography, embolization

Drainage

  • Refractory malignant pleural effusions – PleurX® drainage catheter placement for fluid buildup around the lungs
  • Refractory malignant ascites – PleurX® drainage catheter placement for fluid buildup in the abdomen
  • Abscess drainage tube placement
  • Renal (kidney) – Nephrostomy tubes, ureteral stents
  • Biliary (liver, gallbladder, pancreas) – Biliary drainage tubes, biliary stents

Hyperaldosteronism

A medical condition wherein too much aldosterone is produced by the adrenal glands. Aldosterone helps regulate levels of sodium and potassium in the body, which helps control blood pressure, the distribution of fluids in the body, and the balance of electrolytes in the blood. Too much can cause low potassium levels in the blood.

  • Adrenal vein sampling – To diagnose conditions associated with aldosterone excess or deficiency
