What is Interventional Radiology?

Interventional Radiology is the latest frontier in Medicine, paving new ways and methods of treatment options all done through a 3mm hole in a vessel. Medicine is evolving continuously at a tremendous speed adding years to average life span, unraveling new diseases, and complex presentations. Increased access to technology, restricted physical activities, unhealthy lifestyle is contributing to the constant increase in lifestyle-related disorders such as obesity, varicose veins, high blood pressure and other associated diseases from an earlier age.

Similar to the way all the gadgets have become more sleek and sophisticated, surgical procedures to have become more advanced to a point of day-care solutions being offered to many diseases. In this regard Interventional Radiology has been a torchbearer, imbibing the innovations and uses image guidance in providing minimally invasive and laser-accurate targeted therapies. The spectrum of Interventional Radiology includes pain management, peripheral vascular disease, men’s & woman’s health, cancer, and stoke management. An interventional radiologist provides emergency care like controlling internal bleeder (Embolization) and also electively increasing flow to a non-healing ulcer on foot (Angioplasty). An Interventional Radiologist works in close association with other care providers to provide integrated care and adds significantly to the armamentarium especially when the options are significantly limited.

Almost all the procedures are done under local anesthesia, thereby surgically unfit patients are also taken care of, warding off the risks associated with anesthesia and prolonged stay in the hospital, hence the costs involved are minimized and rapid recovery is ensured. Interventional Radiology uses the imaging modules such as ultrasound, CT and C-arm (X-Rays), and with aid of wires and catheters reaches the target organs via the blood vessels by entering through a small prick of 3mm. The hazards associated with radiation are kept to the lowest possible by constant application of evolving technology and other protective measures.
