Abstract
Dotter first described percutaneous revascularization of peripheral vascular disease (PVD) in 19641. In 1974, Gruentzig developed a balloon catheter for dilation of vascular lesions2. Currently, percutaneous transluminal angioplasty (PTA) employs a variety of devices ranging from implantable stents to endovascular radiation devices for re-stenosis and is recognized as a safe and effective alternative to surgery for selected patients. In addition to the general efficacy of peripheral angioplasty, which is comparable to that of bypass surgery for selected lesions, angioplasty offers several distinct advantages over surgery3 4–5. It is performed under local anaesthesia, making it feasible to treat patients who are at high risk for general anaesthesia. When compared to surgical revascularization, the morbidity from angioplasty is low, generally related to problems at the vascular access site, and mortality is extremely rare. Unlike vascular surgery, there is no recovery period after angioplasty, and most patients can return to normal activity within 24–48 h of an uncomplicated procedure. Finally, angioplasty can be repeated if necessary usually without increased difficulty or increased patient risk compared to the first procedure, and does not preclude surgery as adjunctive or definitive therapy.
