PROGNOSTIC FACTORS IN AORTOILIAC ANGIOPLASTY AND STENTING

Abstract

SUMMARY Percutaneous transluminal angioplasty (PTA) has obtained a definite place in the management of peripheral arterial occlusive disease of the lower limb. It has become widely accepted as a first line treatment for many patients with aortoiliac occlusive disease. The low complication rate and relatively non invasive nature of PTA has made it an increasingly popular intervention. Often, there is a dramatic improvement in the 'presenting symptoms after dilatation as pressure gradients are reduced, flow is improved and distal ischemia is relieved. The concept of endovascular intervention has been well supported by the continuous advance in technology. The rapid evolution of stent design, deployment approaches and adjunctive therapy made the practice of PTA safer and more predictable and has reduced the incidence of procedure related adverse events, particularly the need for emergency surgery.
