This document defines peripheral vascular disease and describes the differences between peripheral arterial and venous disorders. It lists various risk factors for PVD like age, smoking, hypertension, and diabetes. Tests for assessing arterial insufficiency include ankle brachial index, treadmill testing, and skin perfusion pressure measurement. Tests for venous insufficiency include venous filling time, Homan's sign, and Trendelenburg test. Signs and symptoms of arterial disease include pale skin, absent pulses, and painful ulcers. Venous disease presents with warm skin, edema, and less painful ulcers. Grading scales assess severity of venous disease based on symptoms and ulcer characteristics.
