Peripheral arterial occlusive disease (PAOD) occurs when there is a narrowing or blockage – usually a buildup of plaque - within the arteries that reduces blood flow to tissues which can chronic ischemia. As with most diseases, early detection and proactive treatment are important to maximize prognosis. Exercise effectively treats PAOD, but due to ischemic pain in the limbs, or intermittent claudication (IC), exercise can become painful and difficult. Due to the buildup of plaque, occlusions create an ischemic environment that changes the pressure distribution in collateral networks and increases the shear stress in transverse collaterals. Those two responses signal …

Peripheral arterial occlusive disease (PAOD) involves distal artery occlusion by atherosclerotic plaques, which restricts blood flow and leads to ischemia in downstream tissues. Increased blood flow through preexisting collateral vessels leads to increased shear stress that triggers an outward remodeling of the vessel called arteriogenesis. In some cases this natural compensatory mechanism is able to sufficiently restore blood flow following arterial occlusion. However, for many individuals this process is insufficient to relieve peripheral ischemia, and patients experience intermittent claudication, or limb pain with locomotion or exercise. Without treatment, reduced blood flow can lead to tissue necrosis and potentially amputation. The …
