Patients with a variety of illnesses may develop an area of persistent infection (abscess) in the body. The infection can be drained by inserting a catheter through a small nick in the skin to the site of the infection. Also used to treat complications of open surgery.
A ruptured or expanding section of an artery (aneurysm) is contained with fabric-wrapped stents used to “seal” the blood vessel. Also known as an modular endograft or stent graft. Thoracic and abdominal aortic aneurysms and dissections may be treatable from an endovascular approach using endografts.
Minimally invasive treatment of vascular disease has evolved at lightning speed. Led by Dr. Michael E. Pfister, we offer comprehensive treatments for the variety of vascular disorders. Carotid artery stenting and aortic endografts are on the cutting edge of this minimally invasive treatment we offer. In addition, treatment of renal and mesenteric artery stenoses and peripheral vascular disease has become a very rewarding part of our practice.
Aortic and Thoracic Stent Graft
Arteriovenous Malformations (AVM)
Mesenteric Ischemia Treatment
Renal Artery Stenosis/Renovascular Hypertension Treatment
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.
Blood vessel abnormalities can develop at many sites. If untreated, AVMs can rupture, causing life-threatening bleeding. Interventional radiologists can often treat these abnormalities without surgery by guiding thin catheters to the site and injecting a substance that blocks the supply of blood to the affected blood vessels.
Opens blocked or narrowed blood vessels by inserting a very small balloon into the vessel and inflating it. Used to unblock clogged arteries in the legs or arms (called peripheral arterial disease or PAD), kidneys, brain or elsewhere in the body.
An Interventional Radiologist can use a catheter to select stomach veins that have become abnormally and dangerously dilated. Coils and sclerostents are used to close off the abnormal vessels without surgery.
Minimally invasive procedure allowing percutaneous access to obstructed bile ducts. This is often done after failure of an ERCP. A small needle is advanced across the liver using imaging guidance and a drainage tube is introduced to decompress the biliary system. In circumstances of malignant obstruction a completely internalized metal stent may be inserted.
Treatment of carotid artery stenosis in both symptomatic and asymptomatic patients with the use of a stent rather than open surgical repair.
Insertion of a catheter into a vein using imaging guidance so that patients can receive medication or nutrients directly into the blood stream or so blood can be drawn. These can be placed for temporary or semi-permanent use. Most of our oncology patients require ports which are small access devices that are completely implanted beneath the skin on the upper chest.
Delivery of cancer-fighting agents directly to the site of a tumor; currently being used mostly to treat primary and metastatic liver tumors.
Recently, narrowing within neck veins of patients with multiple sclerosis (MS) have been linked with worsening MS symptoms. An interventional radiologist can open these narrowed vessels using a balloon. MS symptoms have improved or resolved as a result of this treatment.
Delivery of clotting agents (coils, plastic particles, gel, foam, etc.) directly to an area that is bleeding, or to block blood flow to a problem area, such as an aneurysm or a fibroid tumor in the uterus.
Feeding tube inserted into the stomach for patients who are unable to take sufficient food by mouth. This can be done using imaging guidance though the skin.
Use of angioplasty, stenting or thrombolysis to open blocked grafts/AVF for hemodialysis.
Diagnostic test for breast, lung, liver, kidney and other cancers; an alternative to surgical biopsy. Biopsy samples are obtained with imaging guidance all over the body and sent to the pathologist for evaluation.
Interventional radiologists can pinpoint the area of internal bleeding with angiography and inject a clotting substance, such as a gelfoam, particles, or tiny coils, through a thin catheter to stop the bleeding. This is often performed in major muscles, lung, stomach, or bowel and organs like the liver, spleen, stomach, and uterus. This life-saving technique often prevents surgery or treats disease when surgery cannot be performed.
Narrowed blood vessels to the bowel can cause pain, weight loss, and tissue injury. A stent can be delivered using angiography techniques in order to improve blood flow.
In some patients with high blood pressure, the condition is caused by a narrowing of the arteries in the kidneys. The problem, called renal artery stenosis, often can be treated with stenting.
A small flexible tube made of plastic or wire mesh, used to hold open clogged blood vessels or other pathways that have been narrowed or blocked by tumors or obstructions.
Cerebral angiography and intracranial catheterization with removal and/or dissolution of clot blocking arteries in the brain to treat patients suffering acute severe stroke symptoms. New technologic advances using stent retrievers allow faster treatment and higher rates of recanalization with improved symptomatic recovery.
Use of heat (RFA) or cold (cryo) energy to kill cancerous tumors. Using imaging guidance, probes are placed into a tumor through the skin in order to treat disease.
A life-saving procedure to improve blood flow and prevent hemorrhage in patients with severe liver dysfunction and cirrhosis.
Dilated painful veins deep in the pelvis and arising from ovaries can be treated with tiny catheters closing off blood flow using coils and scleroscents.
The ureter carries urine from the kidneys to the bladder and sometimes becomes blocked by kidney stones or other obstructions. The interventional radiologist inserts a catheter through a small nick in the skin and into the blocked kidney to drain the urine and can open the ureters with the same technique.
Cuts off the blood supply to the fibroid, causing them to shrink and and symptoms to subside (also known as uterine fibroid embolization). An embolization procedure of uterine arteries to stop life-threatening postpartum bleeding, potentially preventing hysterectomy.
A treatment for “varicose veins” in the scrotum, which can cause male infertility and pain. Using small catheters and imaging guidance, coils and scleroscents are delivered to the plugging vein.
Superficial varicose veins are treated with many techniques. Venous ablation using laser energy and use of liquid injectable sclerosants are the mainstay of treatment.
A tiny cage-like device that is inserted in a major vein to prevent emboli (blood clots) from reaching the lungs. May be placed temporarily and retrieved after weeks to months, or may be placed permanently.
Treatment of Venous disease is a core focus of IVC physicians. No matter where it occurs valve function, flow, and venous anatomy are at the core of finding and treating the cause.
Arteriovenous Malformations (AVM)
Balloon Occlusion Retrograde Transvenous Obliteration of Gastric Varicies
Chronic Jugular Venous Hypertension as a Treatment for Multiple Sclerosis
Hemodialysis Access Maintenance
TIPS (Transjugular Intrahepatic Portosystemic Shunt)
Varicose Vein Treatment
Vena Cava Filter
A pain treatment for fractured vertebra in which medical-grade bone cement is injected into a symptomatic vertebral fracture using imaging guidance.
The minimally invasive treatment of uterine fibroids is one of the most satisfying treatments we perform. By catheterizing the uterine arteries and injecting small particles into the fibroid blood supply, we are able to treat patients without surgery. Recognized by the American College of Obstetrics and Gynecology (ACOG) in 2004 as an accepted treatment, thousands are now performed each year by Interventional Radiologists. This treatment strategy is highly effective and safe in the appropriately selected patient. Uterine fibroid embolization (UFE) is a minimally invasive treatment we provide to our female patients with pain, bulk symptoms, and bleeding who do not want or cannot have hysterectomy or myomectomy. We work closely with your gynecologist to help make the right decision with you.
