Diabetes, hyperlipidemia, hypertension, and tobacco use are important disease risk factors for peripheral vascular disease. Peripheral artery disease is associated with cardiovascular and cerebrovascular complications, and prevalence increases significantly with age, making it a major cause of morbidity in older patients.

Limb claudication is a cramp-like muscle pain that worsens with activity and improves with rest. When patients become symptomatic with peripheral artery disease, they frequently complain of this characteristic pain pattern, which helps distinguish vascular claudication from other causes of leg discomfort.

Patients with chronic venous insufficiency often present with lower extremity swelling, pain, skin changes, and ulceration. These symptoms result from impaired venous return and can significantly impact quality of life if left untreated. Early recognition of these signs is important for appropriate management.

The vascular exam should follow a systematic method beginning with inspection, followed by palpation, and then auscultation. Special maneuvers such as determining the ankle brachial index should be included. The extent of examination depends on the physician's suspicion of underlying peripheral vascular disease and the patient's risk factors.

The peripheral vascular examination includes the upper extremities, lower extremities, and abdomen. A thorough vascular exam in patients with suspected vascular disease should assess all these regions systematically to identify arterial and venous abnormalities and detect signs of disease progression.

Special maneuvers such as determining the ankle brachial index are essential for vascular assessment. Handheld Doppler techniques provide additional diagnostic information and help evaluate blood flow in peripheral vessels. These advanced methods complement the basic inspection, palpation, and auscultation techniques.

In practice, the extent of the vascular exam a physician performs depends on their suspicion of underlying peripheral vascular disease. Patients with or suspected to have risk factors for vascular disease should receive a thorough examination, while the scope may be more limited in lower-risk patients.
