Interventional Radiology

Interventional Radiology is often referred to as "the surgery of the 21st century" because interventional techniques allow radiologists to view the inside of the body guiding narrow tubes or catheters and other very small instruments through the blood vessels and other body pathways to the location of a medical problem. Procedures performed by interventional radiologists (a radiologist who has completed an interventional fellowship training program) are less invasive which results in less pain and risk and are performed at a lower cost.

Aortic Aneurysm Repair (Back To Top)

An aneurysm, or a weakness in the aorta, is an area in the aorta which bulges like a balloon from the pressure of the blood flow and if it grows can burst and hemorrhage or bleed uncontrollably. The aorta is the main blood vessel that carries blood from the heart to the rest of the body. The most common type of aortic aneurysm is an abdominal aortic aneurysm which can often be treated by a non-surgical stent-graft repair procedures.

An incision is made in the groin and a catheter is inserted into the blood vessel that leads to the aorta. A stent-graft which is a Dacron tube inside a metal cylinder is inserted through the catheter. The interventional radiologist watches the progression of the catheter on an x-ray monitor and directs or threads the stent to the location in the aorta where the aneurysm is located. Once the stent-graft is in place, the metal cylinder is expanded like a spring to hold tightly against the wall of the blood vessel. Blood will flow through the stent-graft, avoiding the aneurysm and the aneurysm will typically shrink over time.

Angiography (Back To Top)

Angiography is an x-ray exam of the arteries and veins used to diagnose blood vessel problems and blockages which involves the use of a catheter inserted into an artery. The catheter is inserted through a small nick in the skin that is about the size of a pencil tip, a contrast agent or x-ray dye is then injected to increase the visibility of the blood vessels on the x-ray image.

One of the more common uses of angiography is to determine if there is a blockage or narrowing in the blood vessels that interferes with the normal flow of blood through the body. Often times, the interventional radiologist can treat the blocked blood vessel with angioplasty and thrombolysis techniques. Other reasons for performing angiograms include aneurysms, cerebral vascular disease such as stroke or bleeding in the brain, blood vessel malformations or to diagnose medical conditions that are not resolved with other tests. Angiograms can also be used by surgeons to assist in planning an operation or choosing the appropriate surgical procedure.

Angioplasty/Stent Placement/Thrombolytic Therapy (Back To Top)

Angioplasty is a technique in which the interventional radiologist inserts a very small balloon attached to a thin catheter into a blood vessel in order to open an artery. A small nick is made in the skin and the catheter is inserted into the blood vessel guided by x-ray imaging which assists in finding the appropriate location in which to inflate the balloon to open the artery. A stent, or small metal tube, is often inserted to hold the blood vessel open. In some cases where the blockage is caused by a blood clot, thrombolytic drugs that dissolve clots are injected through the catheter to break-up the clot and restore the blood flow.

These blockages can be caused by peripheral artery disease and in some cases renal vascular hypertension or high blood pressure which is caused by blockage to the artery to the kidney.

Blood Clot Treatment (Back To Top)

Development of blood clots or emboli can be life threatening if they travel to the brain, lungs or heart and effect vital organ function or create an obstruction in the blood supply to that organ. Two interventional procedures are used to reduce the blood clot risks including thrombolysis and filter placement. Thrombolysis involves a process where a catheter is guided to the site of the clot and clot-busting drugs or thromobolytics are infused to break up the clot. Filter placement is a technique used when a blood clot is found in the blood vessels of the leg or deep vein thrombosis. A filter is guided via catheter into the blood vessel, or vena cava, which carries blood to the heart. The filter is used to trap the blood clot before it can reach the heart or lungs.

Central Venous Access (Back To Top)

Interventional Radiologists can place Central Venous Access. Central Venous Access includes Subcutaneous Port for Chemotherapy, Permcathter for Dialysis, and Groshong catheter for longterm antibiotics and total parenteral nutrition (TPN). Typically these are placed under fluoroscopy guidance in the veins of the neck or chest. The Central Venous Access are simple and nearly painless ways to administer medical treatment to patients.

Cancer Treatment - Chemoembolization (Back To Top)

Transcatheter chemoembolization is an interventional procedure where chemotherapy drugs are injected into the liver to kill tumor cells.

A catheter is inserted through a small nick in the skin in the groin and is guided by x-ray image to the liver and the site of the tumor. Contrast agent or dye is injected into the blood vessels to highlight the arteries. The catheter is used to visualize the blood vessels that supplies blood to the tumor where chemotherapy drugs and tiny particles similar to the consistency of sand, are injected. The effect of the injection of the particles is to decrease the blood flow and concentrate chemotherapy in the tumor in order to shrink the tumor size.

IDET (Back To Top)

IntraDiscal Electro Thermal Therapy or IDET is a treatment for patients with painful degenerative disc disease. This is one of the few outpatient treatment options available for pain management of this condition. During the IDET procedure thermal energy is delivered directly to the posterior annular wall via a resistive heating coil. Temperature-controlled nerve fiber destruction shrinks collagenous tissue.

Infertility Treatment (Back To Top)

Interventional radiology procedures provide infertility treatment for men and women. The most common cause of female infertility is a blockage of the fallopian tube. These tubes can become clogged or narrowed, preventing successful pregnancy. A tuboplasty is a procedure where a catheter is placed in the uterus and a contrast agent is injected through the catheter in order to produce an enhanced x-ray image of the uterine cavity and fallopian tubes to determine if and where a blockage exists. If a blockage is identified another catheter is utilized to open the blocked tube.

The major cause of male infertility is varicoceles which are tangled blood vessels, or varicose veins, in the testicles. Through a varicocele embolization procedure a catheter is inserted through a small nick in the skin into the affected vein supplying the testicle. An embolization agent, small balloon or a tiny metal coil can be injected to block off the varicocele. From this procedure the vessel then shrinks which can eliminate the infertility problem.

Pain Procedures (Back To Top)

Pain is considered the fifth vital sign. Managing pain is becoming ever more important in medical care. The interventional radiologists of Riverside Radiology and Interventional Associates, Inc., use their background and training in interventional techniques and minimally invasive medicine to provide a comprehensive approach to pain management including:

Thorough assessment of the patient's pain and development of an effective plan to diagnose, treat, and manage pain.

Services offered include:

  • Consultation

  • Spinal Cord Stimulators

A physician referral is required to have a consultation with the physicians.

Peripheral Vascular Disease (Back To Top)

Peripheral vascular disease often called "hardening of the arteries" is a common circulatory condition in which the arteries that carry blood to the legs, arms, heart, bowels, kidneys, brain and other body parts become narrowed or clogged. This is one of the primary diseases treated by interventional radiologists. There are a number of treatment options offered for PVD including angioplasty, stent or stent-graft placement and thrombolytic therapy.

TIPs (Back To Top)

TIPs or transjuglular intrahepatic portosystemic shunts, is a procedure for treatment of blocked or reduced blood flow to the liver caused by cirrhosis, hepatitis or portal hypertension. A catheter is inserted through a small incision in the skin near the neck and guided via x-ray to create a new opening in the liver between the hepatic artery and portal vein. A stent is inserted to hold open the shunt created by the catheter.

Tumor/Radiofrequency Ablation (Back To Top)

Tumor ablation involves injection of heat, cold or substances such as alcohol, through a catheter to kill cancer cells. Radiofrequency ablation is a technique where a small probe is placed through a catheter device. The probe sends radiofrequency energy to the tumor site to destroy cancerous tissue.

Uterine Fibroid Embolization (Back To Top)

Interventional radiologists perform a relatively new procedure known as uterine fibroid embolization in which a catheter is utilized to embolize the arteries in order to block the supply of blood to fibroid tumors. In this minimally invasive procedure, the reduced or blocked blood supply to the fibroid tumors will cause the tumors to shrink. Uterine fibroids are common tumors in females and are benign growths that develop in the muscular wall of the uterus. The size and location of the fibroids can lead to problems including pain and heavy or prolonged bleeding.

Varicose Veins (Back To Top)

Varicose Veins can be relieved and eliminated with Endovenous Laser Treatment. This is an exciting minimally invasive procedure performed by one of our physicians. A tiny laser catheter is inserted into the faulty vein. The laser's heat seals the impaired vein. The procedure can be done in about one hour and requires minimal recovery. Most insurance companies cover this procedure.

Vertebroplasty (Back To Top)

Vertebroplasty is a therapeutic procedure performed by interventional radiologists which stabilizes broken vertebrae or bones in the spine caused by osteoporosis. A needle is inserted through the skin, into the crushed vertebrae, where surgical bone cement called poly-methylmethacrylate is injected into the bone to stabilize it. More than one crushed vertebrae can be treated in a single procedure. Surgery is not required, because the radiologist is can guide the needle to the exact location via special x-ray equipment. The procedure stops the pain caused by bone rubbing against bone and continuing to fracture. Most patients experience immediate pain relief.
