Increasing use and complexity of interventional fluoroscopy
In 2002, an estimated 657,000 percutaneous transluminal
coronary angioplasty (PTCA) procedures were performed in
adults in the United States. In addition, the rate of coronary
artery stent insertion doubled from 157 to 318 per 100,000
adults, aged 45-64, from 1996 to 2000 (CDC 2004). At the
same time, the complexity of interventional fluoroscopy has been
increasing rapidly. This is due to the development of new
devices and procedures, such as endografts for the treatment of
abdominal aortic aneurysms, the development of vertebroplasty,
kyphoplasty and uterine artery embolization, and increasing use
of fluoroscopic guidance during complex endoscopic biliary and
upper urinary tract procedures. As the complexity of these
procedures has increased, the dose to patients and health care
personnel has increased as well.
