Interventional radiology is an exciting, growing and evolving a subspecialty of radiology. With interventional radiology, both vascular and nonvascular diseases are treated by minimally invasive approaches using small catheters and catheter-based instruments without the need for large surgical incisions or general anesthesia. The procedures are performed with local and intravenous sedation and are guided by radiological imaging techniques such as x-rays, fluoroscopy, ultrasound, Magnetic Resonance Imaging (MRI) and Computed Tomography (CT). The interventional radiologist is trained in radiographic imaging and in percutaneous imaging-guided procedures, and has the clinical skills required to integrate interventional procedures into overall patient management.
Interventional radiology procedures offer a cost-effective health care alternative to certain conventional medical and surgical treatment. The procedures pose less risk to patients and typically decrease hospitalization time. Frequently, interventional procedures are the only viable therapeutic option for critically ill patients unable to tolerate a surgical procedure.
Interventional Neuroradiology
Interventional Neuroradiology (INR) or endovascular surgical neuroradiology has undergone rapid evolution during its short existence. Originally developed in the 1980’s by radiologists and neurological surgeons, INR is made possible by dramatic advances in computer technology and state-of-the-art equipment. Essentially, interventional neuroradiology therapies are accomplished through microcatheters inserted in the groin area and, under X-ray guidance, threaded through the blood vessels leading into the brain.
Interventional neuroradiology currently employs minimally invasive procedures to accomplish a wide variety of treatments including: stroke treatment by delivering clot-busting drugs directly to the site of the blockage; aneurysm therapy by inserting platinum coils into the aneurysm bulge to prevent clotting and rupture; and spinal treatment by injecting cement into a fractured vertebra in order to reinforce the bone.
