Abstract
In addition to specific features of peripheral artery disease (PAD) including intermittent claudication, critical limb ischemia, and acute limb ischemia, the significant increased risk of cardiovascular events in this group of patients cannot be overlooked. The ankle-brachial index (ABI) is the method of choice to screen and establish the diagnosis of PAD. Then duplex ultrasound, CT, and MR angiography or even contrast angiography and DSA are used for better evaluation of PAD diagnosis and for planning of treatment strategy with different indications. Finally, current treatment of PAD is focused mainly on cardiovascular risk modification, supervised exercise training, medical therapy, and endovascular or surgical interventions. The goals of these therapies are improving cardiovascular outcome and functional capacity in addition to preserve limb viability. Currently an endovascular-first approach is the preferred revascularization technique in most PAD patients.
