The 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 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...
متن کاملAnomalous pulmonary venous return with intact atrial septum: diagnosis and pathophysiology.
Twenty-one patients with partial anomalous pulmonary venous drainage with intact atrial septum have been studied. These include 13 patients not previously reported from our laboratories and eight patients with complete hemodynamics reported by others. Methods for identification of this abnormality and for identification of an intact atrial septum are described, including differential indicator ...
متن کاملEpidemiology and pathophysiology of venous thromboembolism: similarities with atherothrombosis and the role of inflammation.
Venous thromboembolism (VTE) is a multifactorial disease. Major provoking factors (e. g. surgery, cancer, major trauma, and immobilisation) are identified in 50-60 % of patients, while the remaining cases are classified as unprovoked. However, minor predisposing conditions may be detectable in these patients, possibly concurring to the pathophysiology of the disease, especially when co-existing...
