Interventional Radiology (IR) is a novel and innovative field in which specialists use image guidance and minimally-invasive tools to perform procedures that would otherwise require open surgery. Most of the time, this means that our patients go home on the day of their procedure with a Band-Aid instead of an incision.
The imaging techniques—X-ray, ultrasound, CT, and MRI—enable interventional radiologists to view specific areas inside the body and to place catheters, insert medical devices, and treat specific areas of disease. IR specialists are radiologists who have additional specialized training and work as part of a multidisciplinary team to determine and provide the best treatments for each patient.
ColumbiaDoctors interventional radiologists perform thousands of IR procedures each year in specialized, angiography suites with dedicated scanners, and have a depth of experience with a range of procedures including treatment for cancer, fibroids, varicose veins, and kidney disease.
Cancer arises when abnormal cells multiply unusually rapidly and accumulate in masses called tumors. Cancer cells are often invasive: they can overrun and destroy normal body tissues, and they can metastasize—spread from their original site to other parts of the body. Doctors have traditionally treated cancer with surgery, radiation therapy, or chemotherapy to try to stop a tumor’s uncontrolled growth.
In interventional radiology, an increasingly important form of cancer therapy, specially trained physicians introduce instruments such as needles or catheters (long, thin tubes) equipped with micro-tools into the body through tiny incisions in the skin. Using imaging techniques such as X-ray, ultrasound, CT, or MRI, they guide the instruments to organ systems throughout the body, and can deliver cancer treatment directly to the tumor. Compared to open surgery, this minimally invasive form of therapy requires less anesthesia, causes less trauma and pain, and patients have shorter hospital stays and recover more quickly.

Varicose Vein Treatment
Varicose veins develop when the vein walls or valves near the surface of the skin become permanently stretched or weakened because of the pressure of the blood flowing through your veins. Varicose veins often appear to be blue, bulging, and twisted and sometimes raised on the surface of the skin. Spider veins, which resemble a spider or spider web, are a mild variation of varicose veins. Unless treated, varicose veins can progress and worsen. Interventional radiologists use two approaches, endovascular laser venous treatment (EVLT) and sclerotherapy, to improve the circulation of blood through your veins and improve the legs’ appearance.
HHT (Hereditary Hemorrhagic Telangiectasia) is a hereditary condition of abnormal blood vessels which affects approximately one in 5,000 people. People with HHT lack certain small capillaries that normally connect arteries to veins. Without these capillaries in key locations, blood flows directly from the artery to the vein, causing very fragile vessels that may bleed or result in other problems.
Because it is a rare disease, many physicians are unaware of the best management strategies for HHT. At Columbia's HHT Center of Excellence, patients have a "home," where they can receive expert care in the diagnosis and treatment of the various manifestations of HHT. Our network of physicians collaborates closely to offer the best care possible to our patients.
