Thromboembolism is a condition in which a blood clot breaks off from its original site and travels through the bloodstream (as an embolus) to obstruct a blood vessel, causing tissue ischemia and organ damage. Thromboembolism can affect both the venous and arterial systems, with different clinical manifestations and management strategies.
While venous thrombosis of the legs is the most common form, venous thrombosis may occur in other veins. These may have particular specific risk factors: [5] Cerebral venous sinus thrombosis, cavernous sinus thrombosis and jugular vein thrombosis: thrombosis of the veins of the brain and head
Various risk factors contribute to VTE, including genetic and environmental factors, though many with multiple risk factors never develop it. [57] [58] Acquired risk factors include the strong risk factor of older age, [5] which alters blood composition to favor clotting. [59] Previous VTE, particularly unprovoked VTE, is a strong risk factor. [60]
Deep vein thrombosis/ right leg Thrombophlebitis causes include disorders related to increased tendency for blood clotting and reduced speed of blood in the veins such as prolonged immobility; prolonged traveling (sitting) may promote a blood clot leading to thrombophlebitis but this occurs relatively less.
Symptoms include liver and kidney failure and vasculitis. [10] Lyme disease* is a disease caused by Borrelia burgdorferi, a spirochaete, and spread by ticks of the genus Ixodes. Symptoms in dogs include acute arthritis, anorexia and lethargy. There is no rash as is typically seen in humans. [11]
This Australian Cattle Dog's obesity poses a health risk for the dog. Obesity is an increasingly common problem in dogs in Western countries. As with humans, obesity can cause numerous health problems in dogs (although dogs are much less susceptible to the common cardiac and arterial consequences of obesity than humans are).
Some other risk factors are poor ejection fraction (<35%), size of infarct, and the presence of AF. In the first three months after infarction, left-ventricle aneurysms have a 10% risk of emboli forming. Patients with prosthetic valves also carry a significant increase in risk of thromboembolism.
A 2006 meta-analysis showed only a 1.3-fold increased risk for coronary disease. [6] Deficiencies in the anticoagulants Protein C and Protein S further increase the risk five- to tenfold. [2] Behind non-O blood type [7] and factor V Leiden, prothrombin G20210A is one of the most common genetic risk factors for venous thromboembolism. [4]
