This is the second edition, after four years, of the original work describing the field of interventional radiology. Much has transpired in the interim, and the new edition is timely and welcome. Those who came to enjoy and rely upon the first edition will be even more pleased with this one, as it will offer even better reference and guidance.
In interventional radiology, radiologists use catheters, guidewires, and other instruments to treat a variety of disease conditions such as occluded arteries, bile ducts, and urinary tracts, and thrombosed veins. Vena caval filters are placed to help prevent pulmonary embolism. Arteriovenous fistulae can be occluded and arteriovenous malformations can be treated by embolotherapy, as can posttraumatic hemorrhaging and certain cases of gastrointestinal bleeding. Interventional radiology also includes placement of indwelling catheters for intravascular treatments or nutrition. Intravascular foreign objects can be removed. Biopsies are performed percutaneously under guidance of computed tomography,
