Superficial vein thrombosis (SVT) is a blood clot formed in a superficial vein, a vein near the surface of the body. Usually there is thrombophlebitis , which is an inflammatory reaction around a thrombosed vein, presenting as a painful induration (thickening of the skin) with redness .
Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
Venous thrombosis is the blockage of a vein caused by a thrombus (blood clot). A common form of venous thrombosis is deep vein thrombosis (DVT), when a blood clot forms in the deep veins. If a thrombus breaks off and flows to the lungs to lodge there, it becomes a pulmonary embolism (PE), a blood clot in the
A right-sided acute deep vein thrombosis (to the left in the image). The leg is swollen and red due to venous outflow obstruction. The most common conditions associated with thrombophilia are deep vein thrombosis (DVT) and pulmonary embolism (PE), which are referred to collectively as venous thromboembolism (VTE).
Thrombosis (from Ancient Greek θρόμβωσις (thrómbōsis) 'clotting') is the formation of a blood clot inside a blood vessel, obstructing the flow of blood through the circulatory system. When a blood vessel (a vein or an artery ) is injured, the body uses platelets (thrombocytes) and fibrin to form a blood clot to prevent blood loss.
Recommendations by clinicians to reduce venous stasis and DVT/PE often encourage increasing walking, calf exercises, and intermittent pneumatic compression when possible. [5] [6] [7] Weakened Venous valves: these are crucial towards ensuring upward flow to the heart from the lower extremities.
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.
After many examples of false-positive Homans' signs were reported, Homans redefined it in 1944, stating that "discomfort need have no part in the reaction", and that increased resistance, involuntary flexure of the knee or pain in the calf upon forced dorsiflexion should be considered positive responses.
