Interventional Radiology

Interventional RadiologyInterventional radiology is a rapidly growing specialty which uses different imaging methods to treat patients and their diseases. The methods used include fluoroscopy (real time X-rays), ultrasound and CAT scans. Using these tools, interventional radiologists introduce small tubes called catheters into patients' bodies to deliver targeted, minimally invasive therapies for a number of medical conditions.

Almost all of the procedures performed by interventional radiologists involve very small incisions and are done under light sedation. Many procedures are performed on an outpatient basis or require only a short hospitalization. In some cases, these therapies have replaced more invasive surgical therapies in the treatment of certain diseases and, therefore, are associated with a shorter recovery period.

Interventional radiologists are physicians who receive their initial training in diagnostic radiology (learning to interpret studies such as CAT scans, ultrasound and MRI) and then receive specialized training in performing advanced procedures using imaging guidance. The interventional radiologists at Lenox Hill Hospital are board-certified by the American College of Radiology in both diagnostic radiology and interventional radiology.

Conditions & Treatments

Interventional radiologists perform a wide array of procedures. Following is a sample of some of them:

  • Uterine artery embolization is a procedure which slows the flow of blood to the uterus in patients who have symptoms from fibroids, such as heavy menstrual bleeding, severe menstrual cramps, and pressure effects from fibroids. The symptoms usually disappear after the fibroids' blood supply has been reduced. Learn more...

  • Varicose vein ablation treats varicose veins in the legs by placing a laser probe into the affected vein and delivering a controlled amount of heat, closing off the varicose vein.

  • Chemoembolization involves injecting chemotherapeutic drugs directly into liver tumors as well as decreasing the blood supply to these tumors with vessel blocking agents. Learn more...

  • Radiofrequency ablation is a procedure where a special needle is placed into tumors of the liver and kidneys, delivering a focused amount of energy that heats the tumors to selectively kill the tumor cells. Learn more...

  • Venous access involves placement of a wide array of catheters into a patient's veins for various reasons such as the administration of chemotherapy (ports), administration of intravenous antibiotics, and access for patients who need dialysis (dialysis catheters).

  • Treatment of vascular diseases such as atherosclerosis, which can cause narrowing of vessels in the arms, legs, and kidneys are treated with minimally invasive techniques. Treatments include opening up these narrowed arteries with balloons or stents or re-opening clotted vessels with medications that dissolve blood clots.
