Peripheral arterial disease (PAD) is a common disorder among older adults. Recognition of the signs and symptoms and appropriate referral of patients to a vascular surgeon can improve functional outcomes and limb salvage. Behavioural, medical, and percutaneous endovascular or open surgical therapies may all be used, depending upon the severity of symptoms and likelihood of limb loss. Cardiovascular comorbidities are common with PAD, and appropriate treatment to minimize cardiovascular mortality is important.
Key words: peripheral arterial disease, claudication, critical limb ischemia, endovascular treatment, lower extremity bypass.
