Multisite artery disease: a common and challenging clinical condition calling for specific management.

'Multisite' artery disease is defined as the simultaneous presence of clinically significant atherosclerotic lesions in at least two major vascular territories. The management of patients with multisite artery disease represents a common challenge in clinical practice, since they are at increased risk for both vascular and coronary surgery. Preliminary experiences suggest that percutaneous treatment may represent a promising strategy for patients with multisite artery disease. In this review, the prevalence and management of multisite artery disease are discussed with particular attention to coronary and peripheral revascularization related issues.
