Vascular Reactivity In Newly-Formed And Mature Arterialized Collateral Capillaries, Sara K. Hellstrom Dec 2014

Vascular Reactivity In Newly-Formed And Mature Arterialized Collateral Capillaries, Sara K. Hellstrom

Master's Theses and Project Reports

Peripheral arterial occlusive disease (PAOD) is a globally-prevalent cardiovascular disease in which atherosclerotic plaques narrow arterial lumen diameters and restrict blood flow to downstream tissues. The impact of these occlusions can be mitigated by collateral vessels that connect parallel arterial branches and act as natural bypasses to maintain perfusion. In animal models that lack collateral arterioles, capillaries that connect terminal arteriolar segments can arterialize and form functional collaterals following an ischemic event; however, in the early stages of development, vasodilation is impaired. We explored the mechanism of impaired vasodilation in arterialized collateral capillaries (ACCs) and pre-existing collaterals (PECs) by evaluating ...

Biomedical Engineering

Peripheral arterial occlusive disease (PAOD) affects approximately 200 million individuals globally. The major underlying cause of PAOD is an inflammatory disease known as atherosclerosis, which results from the build-up of low-density lipoproteins (LDL) in the sub-intimal space. This initiates a complex cascade of events that lead to plaque growth. Plaque growth can then expand into the lumen of the vessel and result in occlusion and/or thrombosis. Symptoms of the disease can include claudication, ulcers, and/or gangrene, although many patients are asymptomatic. Similar to other forms of ischemic disease, risk factors for PAOD include hypertension, diabetes, and smoking. Common ...
