Veins and Arteries
There are significant pathogenic and clinical presentational symptoms that differ with chronic venous insufficiency (CVI) and deep vein thrombosis (DVT). As a provider, it is important to differentiate between both the pathogenic processes and clinical presentation to provide an accurate diagnosis and plan of care. This paper will review the pathophysiology of CVI and DVT, including thrombosis differentiation. The influence of behavioral factors on the pathophysiology, diagnosis, and treatment will additionally be reviewed.
Pathophysiology
An understanding of the pathophysiology and function of both veins and arteries can help clinicians recognize disease processes such as CVI and DVT. According to Huether and McCance (2012), veins are comprised of a thin layer of endothelium and fibrous tissue that exhibits less recoil than arteries. Changes in the endothelium of the vein 's wall will lead to an "exposed subendothelial wall potentiating prothrombogenic and proinflammatory cytokines" (Huether & McCance, 2012). These cellular changes can lead to opportunities for vasoconstriction, platelet adhesion, and inflammatory processes (Huether & McCance, 2012). Furthermore, the function of blood flow back to the heart can be altered when pathogenic changes occur at the cellular level, and there are changes in muscle contraction. Veins have valves that return circulating blood back to the heart. Muscle activity will support blood return by contracting skeletal muscles in the extremities to assist with blood return (Huether & McCance, 2012). Therefore, individuals who have conditions that alter the vessel endothelium such as hypertension or are inactive are at risk for inefficient blood flow back to the heart or...

...ent who presents with these behavioral factors.
Diagnosis of a DVT involves a physical assessment, doppler, and lab tests (D-dimer) (Huether & McCance, 2012). Treatment would need to include anticoagulation therapy or insertion of a superior vena cava (Huether & McCance, 2012). When behavioral factors such as inactivity, obesity, and smoking are present considerations will need to include risk for the presence of other cardiovascular disease processes.
Summary
When caring for patients who exhibit signs of vein disease, it is important to assess and identify vein disease progression. Furthermore, a detailed history and physical will need to include coexisting behavioral factors that can be modified to help prevent further progression of vein disease. Lastly, providing education related to preventative strategies and signs of thrombi formation are essential.
