Operation for acute peripheral arterial occlusion: is it still the gold standard?

Acute arterial ischemia secondary to peripheral arterial occlusion has been shown to cause severe morbidity and mortality. Debate continues about the best mode for initial therapy of patients presenting with acute limb ischemia (ALI). Surgery traditionally has been used as the sole mode of therapy. Since the introduction of catheter-directed thrombolysis (CDT), role of surgery as the "gold standard" has been questioned. In this report the authors review the role of surgery compared with CDT. They discuss the role of prompt diagnosis on the outcome of the intervention and the results of CDT compared with the surgical standard. The best therapy for ALI is the one that is instituted early; intervention should be tailored based on the initial clinical presentation, and surgery remains the gold standard with CDT, an adjunctive tool for the vascular surgeon dealing with acute peripheral arterial occlusion (PAO).
