Thrombophlebitis Alter

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 Varizen Aescusan 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, Thrombophlebitis Alter.

DVT usually occurs in the legs, and is characterized by pain, 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 collapseshock and cardiac Thrombophlebitis Alter. Venous thrombosis may also occur in more Thrombophlebitis Alter places: Thrombophilia has been linked to recurrent miscarriage[10] and possibly various complications of pregnancy such as intrauterine growth restrictionstillbirthsevere Thrombophlebitis Alter 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 condition has also been described in adults. Protein C and Thrombophlebitis Alter S deficiency have also been associated with an increased risk of skin necrosis on commencing anticoagulant treatment with warfarin or related drugs. Thrombophilia Thrombophlebitis Alter be congenital or acquired.

Congenital thrombophilia refers to inborn Thrombophlebitis Alter and usually hereditary, in which case " hereditary thrombophilia " may be used that increase the tendency to develop thrombosis, while, on the Thrombophlebitis Alter hand, acquired thrombophilia Thrombophlebitis Alter 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 keine Schmerzen mit Krampf Beinen typically caused by a deficiency of natural anticoagulants. They are classified as "type I" and are more severe in their propensity to cause thrombosis. Thrombophlebitis Alter 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 Thrombophlebitis Alter 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.

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, 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, Thrombophlebitis Alter. Pregnancy is associated with an increased risk of thrombosis. This probably results from a physiological hypercoagulability in pregnancy that protects against postpartum hemorrhage, Thrombophlebitis Alter.

The female hormone estrogenwhen used in the combined oral contraceptive Thrombophlebitis Alter and in perimenopausal hormone Thrombophlebitis Alter therapyThrombophlebitis Alter, Thrombophlebitis Alter been associated with a two- to sixfold increased risk of venous thrombosis, Thrombophlebitis Alter. The risk depends on the type of hormones used, Thrombophlebitis Alter 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 doubles the risk in numerous studies, particularly in combination with the 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, Thrombophlebitis Alter, and there are higher levels of coagulation proteins such as von Willebrand factor, fibrinogen, factor VII and factor VIII, Thrombophlebitis Alter.

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, Thrombophlebitis Alter.

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, [13] 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 Krampfadern Muskel 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 Thrombophlebitis Alter consistency, which is determined by the levels of coagulation factors 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 thrombin. Thrombin Thrombophlebitis Alter 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 family history of thrombosis. For example, Thrombophlebitis Alter, 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 Thrombophlebitis Alter transient major risk factors such as prolonged immobility, surgery, or trauma, testing for thrombophilia is not appropriate because the Thrombophlebitis Alter of the test would not change a patient's indicated treatment.

In the United Kingdom, professional guidelines give specific indications for thrombophilia Thrombophlebitis Alter. It is recommended that testing be done only after appropriate 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, Thrombophlebitis Alter, 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, Thrombophlebitis Alter.

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, Thrombophlebitis Alter, activated protein C resistance and a general assessment of coagulation through an investigation known as thromboelastography.

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, Thrombophlebitis Alter. Screening this selected group may be beneficial, [24] but even when negative may still indicate residual risk. Thrombophilia screening in people with arterial thrombosis is generally regarded unrewarding and is generally discouraged, Thrombophlebitis Alter, [11] 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 of the underlying disease is needed. Apart Thrombophlebitis Alter 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 it was provoked such as by immobilization or pregnancythe number of previous thrombotic events, male sex, the presence of an inferior vena cava filterthe presence of cancer, symptoms of post-thrombotic syndromeand obesity.

Those with antiphospholipid syndrome may be offered Thrombophlebitis Alter anticoagulation after a first unprovoked episode of thrombosis. The risk is determined by the subtype of antibody detected, by the antibody Thrombophlebitis Alter 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, Thrombophlebitis Alter. Low molecular weight heparin LMWH, such as enoxaparin is generally used as an alternative, Thrombophlebitis Alter. 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 Thrombophlebitis Alter 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. 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 Thrombophlebitis Alter is uncommon in Africans and Asians. The exact prevalence of antiphospholipid syndrome is 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 hematologist Olav Egeberg.

Centers of Disease Control. Antiphospholipid syndrome was described in full in the s, after various previous reports of specific antibodies in people with systemic lupus erythematosus and thrombosis. Hughes, and is often 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 Thrombophlebitis Alter 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 other genetic abnormalities underlying familial thrombosis will in future be discovered through studies of the entire genetic codelooking for small alternations in genes. From Wikipedia, the free encyclopedia, Thrombophlebitis Alter.

Thrombophilia - Wikipedia

Thrombophlebitis throm-boe-fluh-BY-tis occurs when a blood clot blocks one or more of your veins, typically in your legs. Rarely, thrombophlebitis sometimes called phlebitis can affect veins in your arms or neck. The affected vein may be near the surface of your skin, Thrombophlebitis Alter, causing superficial thrombophlebitis, Thrombophlebitis Alter, or deep within a muscle, causing deep vein thrombosis DVT.

Thrombophlebitis can be caused by trauma, surgery or prolonged inactivity. Superficial thrombophlebitis may occur in people with varicose veins. A clot in a deep vein increases your risk of serious health problems, Thrombophlebitis Alter, including the possibility of a dislodged clot embolus traveling Thrombophlebitis Alter your lungs and blocking an artery there pulmonary embolism.

Deep vein thrombosis is usually treated with blood-thinning medications. Superficial thrombophlebitis is sometimes treated with blood-thinning medications, too. When a vein close to the surface of your skin is affected, you may see a red, Thrombophlebitis Alter, hard and tender cord just under the surface of your skin.

When a deep vein in the leg is affected, your leg may become swollen, tender and painful. See your doctor right away if you Thrombophlebitis Alter a red, Thrombophlebitis Alter, swollen or tender vein — especially if you have one or more risk Thrombophlebitis Alter for thrombophlebitis. If you have leg swelling and pain along with shortness of breath or chest pain that hurts when you take a deep breath, go to an emergency room, Thrombophlebitis Alter.

These signs and symptoms may indicate deep vein thrombosis, which increases your risk of a dislodged blood clot traveling through your veins to your lungs. The cause of thrombophlebitis is a blood clot. Blood clots can be caused by many different things — namely anything that causes your Thrombophlebitis Alter not to circulate properly.

It's possible a blood clot that causes thrombophlebitis could be caused by:, Thrombophlebitis Alter. The more risk factors you have, the higher your risk of thrombophlebitis. If you have Thrombophlebitis Alter or more risk factors, be sure to Thrombophlebitis Alter prevention strategies with your doctor before long periods of inactivity, such as after an elective surgery or during a long flight or car ride.

If thrombophlebitis is in a vein just under your skin superficial veinThrombophlebitis Alter, complications are rare. However, if the clot occurs in a deep vein you may develop a serious medical condition known as deep vein thrombosis, Thrombophlebitis Alter. If that happens, the risk of serious complications is greater. Deep vein thrombosis also may damage valves in the veins in your legs. Veins have valves to prevent blood from flowing back as it is gradually pushed uphill toward your heart.

When the valves in the veins of your legs don't work properly, several problems can occur:. If you have symptoms of thrombophlebitis, such as a red, swollen or tender vein, see your doctor right away. If the vein swelling and pain are severe or you have other symptoms that might indicate a blood clot traveling to your lungs, such as shortness of breath or coughing up blood, call or your local emergency number.

If you have time before your appointment, Thrombophlebitis Alter, here's some information that may help you get ready for your appointment, and what to expect from your doctor. Your time with your doctor is limited, so preparing a list of questions will help you make the most of your time together.

List your questions from most important to least important in case time runs out. For thrombophlebitis, Thrombophlebitis Alter, Thrombophlebitis Alter basic questions to ask your doctor include:. Your doctor is likely to ask you a number of questions, Thrombophlebitis Alter. Being ready to answer them may reserve time to go over any points you want to spend more time on. Your doctor may ask:. Before your doctor appointment, Thrombophlebitis Alter, you can begin some self-care measures.

You can use a warm washcloth as a compress on the affected area, and elevate the affected leg to help with any discomfort. If you Thrombophlebitis Alter to take a pain reliever, Thrombophlebitis Alter, such as ibuprofen Advil, Motrin IB, othersbe sure to tell your doctor. Medications can interact with other blood clot-dissolving medications your doctor prescribes. To diagnose thrombophlebitis, your doctor will ask you about the discomfort you've had and then look for any affected veins near the surface of your skin.

To determine whether you have superficial thrombophlebitis or deep vein thrombosis, your doctor may choose one of these tests:. If thrombophlebitis occurs in a vein just under your skin, your doctor may recommend self-care steps that include applying heat to the painful area, elevating the affected leg and using an over-the-counter nonsteroidal anti-inflammatory drug NSAID.

The condition usually doesn't require hospitalization and improves significantly within a month. Your doctor may also recommend these treatments for thrombophlebitis, including deep vein thrombosis:.

In addition to medical treatments, there are some self-care measures you can take to help improve thrombophlebitis. If you're taking warfarin, ask your doctor Thrombophlebitis Alter you need to alter your diet. Foods high in vitamin K, Thrombophlebitis Alter, such as leafy Thrombophlebitis Alter vegetables and canola oil, can affect the way this medication works.

Aspirin isn't recommended for people taking warfarin Coumadin because it could thin your blood too much. Let your doctor know if you're already taking aspirin for another reason. Sitting during a long flight or car ride can cause swollen ankles and calves. The inactivity also increases your risk of thrombophlebitis in the veins of your legs.

Thrombophlebitis Alter help prevent a blood clot from forming:, Thrombophlebitis Alter. On flights or for car rides lasting more than four hours, take additional precautions to reduce your risk of deep vein Thrombophlebitis Alter. If you're at increased risk of deep vein thrombosis, talk to your doctor before your flight.

Published September 18, Definition Thrombophlebitis throm-boe-fluh-BY-tis occurs when a blood clot blocks one or more of your veins, typically in your legs. Symptoms Superficial thrombophlebitis symptoms include: Warmth, tenderness and pain in the affected area Redness and swelling Deep vein thrombosis symptoms include: Pain Swelling When a vein close to the surface of your skin is affected, you may see a red, hard and tender cord just under the surface of your skin.

When to see a doctor See your doctor right away if you have a red, swollen or tender vein — especially if you have one or more risk factors for thrombophlebitis. Causes The Thrombophlebitis Alter of thrombophlebitis is a blood clot, Thrombophlebitis Alter. It's possible Thrombophlebitis Alter blood clot that causes thrombophlebitis Thrombophlebitis Alter be caused by: An injury to a vein An inherited blood-clotting disorder Being immobile for long periods of time, such as during a hospital stay.

Risk factors Your risk of thrombophlebitis increases if you: Are confined to bed for a prolonged time, such as after surgery, after a heart attack or after an injury, such as breaking your leg Have had a stroke that caused your arms or legs to be paralyzed Have a pacemaker or have a thin, flexible tube catheter in a central vein, Thrombophlebitis Alter, for treatment of a medical condition, Thrombophlebitis Alter, which may irritate the blood vessel wall and decrease blood flow Are pregnant or have just given birth, which may mean you have increased pressure in the veins of your pelvis and legs Use birth control pills or hormone replacement therapy, which may make your blood more likely to clot Have a family history of a blood-clotting disorder or a tendency to form blood clots easily Are inactive for a long period of time, such as from sitting in a car or an airplane Are older than 60 Have varicose veins, which are a common Thrombophlebitis Alter of superficial thrombophlebitis The more risk factors you have, the higher your risk of thrombophlebitis.

Complications If thrombophlebitis is in a vein just under your skin superficial veincomplications are rare. If part of a deep vein clot becomes dislodged, Thrombophlebitis Alter, it may travel to your lungs, Thrombophlebitis Alter, where it can block an artery embolism and cause a potentially life-threatening situation. This Thrombophlebitis Alter, also known as post-thrombotic syndrome, Thrombophlebitis Alter, can develop months or even years after you've had deep vein thrombosis.

Post-phlebetic syndrome can cause lasting and possibly disabling pain, swelling and a feeling of heaviness in the affected leg. The use of compression stockings for two years or longer after deep vein thrombosis can help prevent or treat this condition. When the valves in the veins of your legs don't work properly, several problems can occur: The pooling of blood in your veins Thrombophlebitis Alter cause them to balloon, resulting in varicose veins.

In some cases, the pooling may become so bad that your leg swells edema. With chronic swelling and increased pressure on your skin, discoloration may occur. Sometimes, skin ulcers may develop. If you suspect a skin ulcer is forming, call your doctor. Preparing for your appointment If you have symptoms of thrombophlebitis, such as a red, swollen or tender vein, see your doctor right away. What you can do Write down any symptoms you're experiencing, including any that may seem unrelated to thrombophlebitis.

Write down key personal information, especially if you have a family history of blood-clotting disorders, or if you've been inactive for long periods of time recently, such as traveling by car or plane, Thrombophlebitis Alter. Also, if you're planning to travel and are concerned about your thrombophlebitis risk, tell your doctor about your travel plans. Make a list of all medications, vitamins and supplements that you're taking. Have someone take you to the doctor or emergency room, if possible.

It may be difficult for Thrombophlebitis Alter to drive, and it's helpful to have someone with you at your appointment to help you remember everything your doctor tells you. If you have Thrombophlebitis Alter of a pulmonary embolism, such as chest pain or shortness of breath, call or your local emergency number for immediate assistance.

Write down questions to ask your doctor, Thrombophlebitis Alter. For thrombophlebitis, Thrombophlebitis Alter, some basic questions to ask your doctor include: What is likely causing my condition?
