Pathophysiology of Intermittent Claudication in Peripheral Artery Disease.
Peripheral artery disease (PAD) affects more than 200 million adults worldwide. Patients with lower extremity PAD have a heightened risk for cardiovascular events because of the systemic nature of atherosclerosis, and benefit from treatment with risk factor-modifying therapies. Limb symptoms in PAD include intermittent claudication and diminished walking ability. Arterial obstruction from ather...
متن کاملThe microvascular pathophysiology of chronic venous insufficiency.
Severe chronic venous insufficiency (CVI) demonstrates as chronic, hard-to-heal wounds of the lower extremity. The wound is the result of poor skin perfusion due to a complex series of pathologic events, often initiated by a deep vein thrombosis (DVT). As years pass, the DVT causes venous valvular damage and incompetence. The calf muscle pump fails to augment venous return, and venous blood pre...
متن کاملClaudication
may be no blood-flow through the calf muscle of a claudicant during certain forms of exercise, in particular when the patient rhythmically raises himself up and down on tiptoe of one leg. It may also be true of an athlete that there is no bloodflow through his calf muscles when performing short and rapid sprints like running 100 yards in 10 seconds. My interest in this subject started when I fo...
متن کاملReview Article Pathophysiology of Cerebral Venous Thrombosis - An overview
Cerebral venous sinus thrombosis is a disorder with a unique pathophysiology which needs to be described.A Medline search of all articles detailing pathophysiology of CVST was done, using keywords: cerebral venous thrombosis and pathophysiology. In addition, major texts were reviewed for additional references. The pathophysiology of CVST depends on two interconnected events, local signs due to ...
متن کاملVenous Admixture in COPD: Pathophysiology and Therapeutic Approaches
Chronic obstructive and interstitial lung diseases impair pulmonary gas exchange leading to wasted ventilation (alveolar dead space) and wasted perfusion (venous admixture). These two fundamental types of abnormality represent opposite ends of the spectrum of ventilation-perfusion mismatch with V/Q ratios of infinity and zero. Treatment approaches that improve airway function, reduce air trappi...
