Www Thrombophlebitis ist Akute Thrombophlebitis ist
Thrombophilia sometimes hypercoagulability or a prothrombotic state is an abnormality of blood coagulation that increases the risk of thrombosis blood clots in blood vessels. There is no specific treatment for most thrombophilias, but recurrent episodes of thrombosis may be an indication for long-term preventative anticoagulation.
The most common conditions associated with thrombophilia are deep vein thrombosis DVT and pulmonary embolism PEwhich are referred to collectively as venous thromboembolism VTE. DVT usually occurs in the legs, and is characterized by pain, www Thrombophlebitis ist, swelling and redness of the limb. It may lead to long-term swelling and heaviness due to damage to valves in the veins. Depending on the size and the location of the clot, this may lead to sudden-onset shortness of breathchest painpalpitations and may be complicated by collapsewww Thrombophlebitis ist, shock and cardiac arrest.
Venous thrombosis may also occur in more unusual places: Thrombophilia has been linked to recurrent miscarriage and possibly various complications of pregnancy such as intrauterine growth restrictionstillbirthsevere pre-eclampsia and abruptio placentae. Protein C deficiency may cause purpura fulminansa severe clotting disorder in the newborn that leads to both tissue death and bleeding into the skin and other organs.
The www Thrombophlebitis ist has also been described in adults. Protein C and protein S www Thrombophlebitis ist have also been associated with an increased risk of skin necrosis on commencing anticoagulant treatment with warfarin or related drugs. Thrombophilia can be congenital or acquired. Congenital thrombophilia refers to inborn conditions www Thrombophlebitis ist usually hereditary, www Thrombophlebitis ist, in which case " hereditary thrombophilia " may be used that increase the tendency to develop thrombosis, while, on the other hand, acquired thrombophilia refers to conditions that arise later in life.
The most common types of congenital thrombophilia are those that arise as a result of overactivity of coagulation factors. They are relatively mild, and are therefore classified as "type II" defects. The rare forms of congenital thrombophilia are typically caused by a deficiency of natural anticoagulants. They are classified as "type I" and are more severe in their propensity to cause thrombosis.
Blood group determines thrombosis risk to a significant extent. O blood group is associated with reduced levels of von Willebrand factor — because of increased clearance — and factor VIII, which is related to thrombotic risk. A number of acquired conditions augment the risk of thrombosis. In some cases antiphospholipid syndrome can cause arterial as well as venous thrombosis. It is also more strongly associated with miscarriage, and can cause a number of other symptoms such as livedo reticularis of the skin and migraine, www Thrombophlebitis ist.
Heparin-induced thrombocytopenia HIT is due to an immune system reaction against the anticoagulant drug heparin or its derivatives. PNH increases the risk of venous thrombosis but is also associated with hemolytic anemia anemia resulting from destruction of red blood cells. Hematologic conditions associated with sluggish blood flow can increase risk for thrombosis. For example, sickle-cell disease caused by mutations of hemoglobin is regarded as a mild prothrombotic state induced by impaired flow.
Again, www Thrombophlebitis ist, these conditions usually warrant specific treatment when identified. Cancerparticularly when metastatic spread to other places in the bodyis a recognised risk factor for thrombosis. Furthermore, particular cancer treatments such as the use of central venous catheters for chemotherapy may increase the risk of thrombosis further. Various mechanisms have been proposed. Pregnancy is associated with an increased risk of thrombosis.
This probably results from a physiological hypercoagulability in pregnancy that protects against postpartum hemorrhage. The female hormone estrogenwhen used in the combined oral contraceptive pill and in perimenopausal hormone replacement therapyhas been associated with a two- to sixfold increased risk of venous thrombosis.
The risk depends on the type of hormones used, the dose of estrogen, and the presence of other thrombophilic risk factors. Obesity has long been regarded as a risk factor for venous thrombosis. It more than www Thrombophlebitis ist the risk in numerous studies, www Thrombophlebitis ist, particularly in combination with www Thrombophlebitis ist use of oral contraceptives or in the period after surgery.
Various coagulation abnormalities have been described in the obese. Plasminogen activator inhibitor-1an inhibitor of fibrinolysis, is present in higher levels in people with obesity. Obese people also have larger numbers of circulating microvesicles fragments of damaged cells that bear tissue factor. Platelet aggregation may be increased, and there are higher levels of coagulation proteins such as von Willebrand factor, fibrinogen, factor VII and factor VIII.
Obesity also increases the risk of recurrence after an initial episode of thrombosis. A number of conditions that have been linked with venous thrombosis are possibly genetic and possibly acquired. Activated protein C resistance that is not attributable to factor V mutations is probably caused by other factors and remains a risk factor for thrombosis.
There is an association between the blood levels of homocysteine and thrombosis,  although this has not been reported consistently in all studies. Thrombosis is a multifactorial problem because there are often multiple reasons why a person might develop thrombosis. These risk factors may include any combination of abnormalities in the blood vessel wall, abnormalities in the blood flow as in immobilizationand abnormalities in the consistency of the blood. Thrombophilia is caused by abnormalities in blood consistency, which is determined by the levels of coagulation www Thrombophlebitis ist and other circulating blood proteins that participate in the "coagulation cascade".
Normal coagulation is initiated by the release of tissue factor from damaged tissue. Tissue factor binds to circulating factor VIIa. Factor Xa in the presence of factor V activates prothrombin into www Thrombophlebitis ist. Thrombin is a central enzyme in the coagulation process: In thrombophilia, the balance between "procoagulant" and "anticoagulant" activity is disturbed.
The severity of the imbalance determines the likelihood that someone develops thrombosis. In addition to its effects on thrombosis, hypercoagulable states may accelerate the development of atherosclerosisthe arterial disease that underlies myocardial infarction and other forms of cardiovascular disease. There are divergent views as to whether everyone with an unprovoked episode of thrombosis should be investigated for thrombophilia.
Even those with a form of thrombophilia may not necessarily be at risk of further thrombosis, while recurrent thrombosis is more likely in those who have had previous thrombosis even in those who have no detectable thrombophilic abnormalities. It is more likely to be cost-effective in people with a strong personal or www Thrombophlebitis ist history of thrombosis.
For example, www Thrombophlebitis ist, if the thrombosis is due to immobilization after recent orthopedic surgeryit is regarded as "provoked" by the immobilization and the surgery and it is less likely that investigations will yield clinically important results.
When venous thromboembolism occurs when a patient is experiencing transient major risk factors such as prolonged immobility, surgery, or trauma, testing for thrombophilia is not appropriate because the outcome of the test would not change a patient's indicated treatment. In the United Kingdom, professional guidelines give specific indications for thrombophilia testing. It is recommended that testing be done only after www Thrombophlebitis ist counseling, and hence the investigations are usually not performed at the time when thrombosis is diagnosed but at a later time.
In other rare conditions generally linked with hypercoagulability, such as cerebral venous thrombosis and portal vein thrombosis, there is insufficient data to state for certain whether thrombophilia screening is helpful, and decisions on thrombophilia screening in these conditions are therefore not regarded as evidence-based. Recurrent miscarriage is an indication for thrombophilia screening, particularly antiphospholipid antibodies anti-cardiolipin IgG and IgM, as well as lupus anticoagulantfactor V Leiden and prothrombin mutation, activated protein C resistance and a general assessment of coagulation through an investigation known as thromboelastography, www Thrombophlebitis ist.
Women who are planning to use oral contraceptives do not benefit from routine screening for thrombophilias, as the absolute risk of thrombotic events is low. If either the woman or a first-degree relative has suffered from thrombosis, the risk of developing thrombosis is increased.
Screening this selected group may be beneficial,  but even when negative may still indicate residual risk. Thrombophilia screening in people with arterial thrombosis is generally regarded unrewarding and is generally discouraged,  except possibly for unusually young patients especially when precipitated by smoking or use of estrogen-containing hormonal contraceptives and those in whom revascularization, such as coronary arterial bypassfails because of rapid occlusion of the graft.
There is no specific treatment for thrombophilia, unless it is caused by an underlying medical illness such as nephrotic syndromewhere the treatment www Thrombophlebitis ist the underlying disease is needed.
Apart from the abovementioned forms of thrombophilia, the risk of recurrence after an episode of thrombosis is determined by factors such as the extent and severity of the original thrombosis, whether www Thrombophlebitis ist was provoked such as by immobilization or pregnancythe number of previous thrombotic events, male sex, the presence of www Thrombophlebitis ist inferior www Thrombophlebitis ist cava filterthe presence of cancer, symptoms of post-thrombotic syndromeand obesity.
Those with antiphospholipid syndrome may be offered long-term anticoagulation after a first unprovoked episode of thrombosis.
The risk is determined by the subtype of antibody detected, by the antibody titer amount of antibodieswhether multiple antibodies are detected, and whether it is detected repeatedly or only on a single occasion. Women with a thrombophilia who are contemplating pregnancy or are pregnant usually require alternatives to warfarin during pregnancy, especially in the first 13 weeks, when it may produce abnormalities in the unborn child.
Low molecular weight heparin LMWH, such as enoxaparin is generally used as an alternative. When women experience recurrent pregnancy loss secondary to thrombophilia, some studies have suggested that low molecular weight heparin reduces the risk of miscarriage.
When the results of all studies are analysed together, no statistically signifiant benefit could be demonstrated. People with factor V Leiden are at a relatively low risk of thrombosis, but may develop thrombosis in the presence of an additional risk factor, such as immobilization.
Most people with the prothrombin mutation GA never develop thrombosis. The major "type 1" thrombophilias are rare. Antithrombin deficiency is present in 0. Protein C deficiency, too, is present in 0, www Thrombophlebitis ist. The exact prevalence of protein S deficiency in the population is unknown; it is found 1. The minor "type 2" thrombophilias are much more common. Like factor V Leiden, this abnormality is uncommon in Africans and Asians.
The exact prevalence of antiphospholipid syndrome www Thrombophlebitis ist not well known, as different studies employ different definitions of the condition. German physician Rudolf Virchow categorized abnormalities in the consistency of the blood as a factor in the development of thrombosis in The exact nature of these abnormalities remained elusive until the first form of thrombophilia, antithrombin deficiencywas recognized in by the Norwegian www Thrombophlebitis ist Olav Egeberg.
Centers of Disease Control. Antiphospholipid syndrome was described in full in the s, after various previous reports of specific antibodies www Thrombophlebitis ist people with systemic lupus erythematosus and thrombosis. Hughes, and is www Thrombophlebitis ist referred to as Hughes syndrome for that reason. The more common genetic thrombophilias were described in the s. Many studies had previously indicated that many people with thrombosis showed resistance activated protein C.
In a group in LeidenThe Netherlands, identified the most common underlying defect—a mutation in factor V that made it resistant to the action of activated protein C. The defect was called factor V Leidenas genetic abnormalities are typically named after the place where they are discovered. It is suspected that www Thrombophlebitis ist genetic abnormalities underlying familial thrombosis will in future be discovered through studies of the entire genetic codelooking for small alternations in genes.
