What are the complications of angioplasty? The types and incidence of complications vary with the location and morphology of the lesion. Complications include spasm, flow-limiting dissection, plaque embolization, vessel rupture, access site trauma, renal dysfunction, or allergic reaction to iodinated contrast material, and rarely death.
What constitutes a technically successful angioplasty? • Restoration of luminal diameter with <30% residual stenosis. • A pressure gradient <5 mm Hg across the lesion. • Absence of a flow-limiting dissection or vessel rupture. • Relative reduction in the number and caliber of collateral vessels seen on angiography.
What are the basic steps in performing an angioplasty procedure? A thorough diagnostic arteriogram is performed first. This is important so that the lesion can be sized and an appropriate angioplasty balloon can be selected. The patient is then given heparin. It is important to give heparin before crossing the lesion to prevent thrombosis. The …
What are the clinical categories of acute limb ischemia? Clinical Categories of Acute Limb Ischemia CATEGORY DESCRIPTION CAPILLARY RETURN MUSCLE WEAKNESS SENSORY LOSS ARTERIAL DOPPLER SIGNAL VENOUS DOPPLER SIGNAL Viable Not immediately threatened Intact None None Audible (ankle pressure >30 mm Hg) Audible Threatened Salvageable if promptly treated Intact, but slow Mild, partial Mild, incomplete Inaudible Audible …
What is the Rutherford Becker classification system? The Rutherford staging system for CLTI describes six clinical categories of lower extremity ischemia, from Rutherford 0 (R0) patients who are asymptomatic to R6 patients who have major tissue loss extending above the trans-metatarsal level, with a functional foot that is regarded as non-salvageable (Rutherford et al. 1997). R6 …
What is the Fontaine classification? The Fontaine classification is a widely used classification system for lower extremity ischemia. It describes four stages based on signs and symptoms. • Stage 1 is asymptomatic disease. • Stage 2a is intermittent claudication when walking more than 200 m. • Stage 2b is intermittent claudication when walking less than 200 m. • Stage 3 is …
Why is it important to identify patients with claudication? PAD affects more than 10 million Americans, and its prevalence is increasing. PAD is an important marker for many other serious conditions, including coronary artery disease, cerebrovascular disease, aneurysms, diabetes mellitus, and hypertension. Patients with PAD have a 4- to 6-fold increased cardiovascular mortality compared to …
