Interventional Radiology

Interventional Radiology

Chaitanya Ahuja, MD

Interventional radiologist perform sophisticated procedures through small incisions using thin, flexible catheters inserted into blood vessels and watching with real-time ultrasound or X-rays. Minimally invasive techniques like these can treat everything from a bleeding stomach to cancer.

Treatment of Liver Cancer

Minimally invasive treatments for liver cancer include tumor ablation and tumor embolization. Thermal ablations are performed using radiofrequency, microwave and cryoablation. In chemoembolization therapy with drug-eluting beads, the radiologist places tiny spheres into the cancerous part of the liver; the spheres stick in place and gradually release high-dose chemotherapy to that specific region. Similarly, yttrium-90 radioembolization uses beads to deliver radiation directly to a tumor, limiting exposure to healthy areas.

Treatment of Lung Cancer

The interventional radiologist treats lung cancer by microwave and cryoablation (killing the tumor cells by rapid freeze-thaw cycles). This treatment causes minimal discomfort to the patient and is successful in treatment of the cancer.

Treatment of Kidney (Renal) Cancer

Thermal ablation of renal cancer, this treatment can be performed in the CT scanner with minimal blood loss.

Treatment of Portal Hypertension

Interventional radiology techniques can be used to treat portal hypertension, a common result of cirrhosis of the liver. The interventional radiologist performs treatments using TIPS ( Transjugular Intrahepatic Portosystemic Shunt ), DIPS ( Direct Intrahepatic Portocaval Shunt ) and BRTO ( Balloon-Occluded Retrograde Transvenous Obliteration).
