Jul 14, Author: In superficial UFO mit Krampfadern, acute-onset pain and swelling usually occur over a previous varicose vein. At times, this pain and swelling, which is often associated with warm erythema, can appear even without an obvious underlying varicosity.

Swelling and pain in an upper extremity are suggestive of thrombosis. Pain associated with SVT is usually localized over the site of thrombosis. Pain associated with DVT is generally more diffuse and more common in the lower extremities than elsewhere. Recent surgery especially Manifestation von Thrombophlebitis surgerytrauma, immobilization, or prolonged bed rest are factors that can contribute to SVT or DVT. Inquire about a history or symptoms suggestive of heart disease or congestive Trainer Fahrrad Krampf failure; relevant findings include dizziness, Manifestation von Thrombophlebitis extremity swelling, and weight gain.

Obtain an accurate obstetric history in female patients. Recurrent spontaneous abortions may suggest an underlying factor deficiency.

Because hypercoagulability occurs in association with a number of malignancies, a history or symptoms suggestive of malignancy eg, Manifestation von Thrombophlebitis, fever, bone pain, weight loss, bruising, fatigue should be investigated in individuals without other known risk factors for thrombosis.

Risk factors in the healthy flying population include factors of immobilization associated with prolonged chair-rest deconditioning, including dehydration, hypovolemia, increased viscosity of the blood, and reduced venous blood flow, Manifestation von Thrombophlebitis. Illicit drug use can be a factor. Cannibis use has been attributed as a cause of SVT in a case report. The classic findings of SVT are a firm, tender, erythematous fibrous cord, usually in the area of a previous varicose or normal-appearing vein.

In cases of DVT, mild-to-moderate edema, erythema, and tenderness prevail. Predisposing factors include any event that can reduce venous flow; examples include prolonged sitting or immobilization and dehydration eg, as on a long airline flightlong surgery, or prolonged bed rest.

Internal trauma to a vein due to an indwelling catheter or even a difficult phlebotomy procedure can also cause venous injury Manifestation von Thrombophlebitis inflammation.

Manifestation von Thrombophlebitis

During the last decade much progress has been made toward better understanding of the underlying reasons causing thromboembolism in children. A considerable number of acquired and hereditary thrombotic risk factors have been identified which may also Manifestation von Thrombophlebitis an impact on therapeutic decisions and prognosis concerning outcome and the risk Manifestation von Thrombophlebitis a second event.

However, indications for therapeutic interventions, such as thrombolysis and prophylactic anticoagulation with respect to the Manifestation von Thrombophlebitis clinical conditions and their combination with other risk factors, are not yet well defined. The following article describes the causes, clinical presentation and management of thrombosis in neonates, infants and older children, focusing on the clinically most relevant conditions. Thromboembolism TE is still regarded as a rare event in childhood and therefore knowledge of diagnostics, therapy and prophylaxis is limited among general pediatricians.

During the past years, however, it is increasingly recognized as having significant impact on mortality, chronic morbidity and the normal development of children, which has led to an enhanced sensitivity toward considering such events in respective patients. Besides the greater awareness, an objective increase in childhood thrombosis is due to the medical progress in the treatment of critically ill patients. This seemingly contradictory observation is easily explained by Manifestation von Thrombophlebitis increasing use of central catheters and innovative interventional procedures in the treatment of premature infants, neonates and older children who are critically ill, suffering from complex cardiac defects, and from malignant disease, respectively.

Therapeutic and prophylactic measures have subsequently become increasingly important, but in addition to the complexity of the clinical background and the heterogeneity in the pattern of acquired and inherited risk factors for TE among patients, the physiological significant Manifestation von Thrombophlebitis of the coagulation system between newborns, young children and adolescents and differences in drug metabolism do not allow general recommendations for therapeutic interventions like thrombolysis and prophylactic anticoagulation for the different clinical conditions.

This situation is further complicated by a lack of availability of pediatric formulations and pediatric data for new drugs. The increasing knowledge of exogenous and endogenous thrombophilic risk factors has initiated a number of studies to assess the impact of such factors with respect to their contribution to the thrombophilic state, both individually but also in concert with other factors. In addition to their impact on a first thrombotic event, much of the interest is now focused on their importance for thrombotic relapses.

Only such studies will give us an answer to questions concerning the indications for treatment, prophylaxis and its optimal duration. The annual incidence of TE in childhood in general is considerably lower than in adults, with a reported frequency of 0. The results of a prospective German study suggested an incidence of 5.

The estimated yearly incidence of stroke in childhood is between 3—8 perManifestation von Thrombophlebitis, In addition to its impact on the development of children, stroke also quantitatively Manifestation von Thrombophlebitis the most important role, Manifestation von Thrombophlebitis.

There Manifestation von Thrombophlebitis two age-related peaks in the frequency of thromboembolic disorders in children and adolescents: The relatively higher incidence in neonates as compared to older children may be due to higher hematocrit, Manifestation von Thrombophlebitis, and the greater lability of the hemostatic system in neonates due to the generally decreased levels of both coagulation factors and their inhibitors in this age group, except factor VIII FVIII and von Willebrand factor VWF which are normal or even elevated, Manifestation von Thrombophlebitis.

Clearly, these epidemiological data have to be considered when assessing the Manifestation von Thrombophlebitis absolute thrombotic risk of children with thrombophilia. Pain, swelling and discoloration of extremities are acute symptoms of deep vein thrombosis DVT.

Vena cava inferior thrombosis manifests with prominent cutaneous veins and possibly liver or renal dysfunction depending on the site and extension of the thrombus. Superior vena cava thrombosis leads to cyanosis and swelling of the head and upper thorax with prominent collateral veins and may finally result in acute cardiac failure. Portal vein thrombosis, Manifestation von Thrombophlebitis, in most cases due to central catheters, and renal vein thrombosis with hematuria as a frequent sign may result in functional impairment or even failure of liver and renal function, respectively.

Acute chest pain and dyspnea could suggest pulmonary embolism. Acute Manifestation von Thrombophlebitis, visual impairment, cerebral convulsions and signs of venous congestion may indicate sinus venous thrombosis.

Childhood arterial ischemic stroke AIS manifests in neonates preferentially with seizures and abnormalities of muscle tone, whereas in elder children hemiparesis is the most frequent neurologic sign, Manifestation von Thrombophlebitis. Thrombotic thrombocytopenic purpura TTPa severe microangiopathic disorder is characterized by nonimmunologic hemolytic anemia and thrombocytopenia, neurologic symptoms, and renal, pulmonary and cardial involvement.

Every thrombotic event initiates a particular response to re-establish the balance of the hemostatic system, e. Subsequently markers of fibrinolysis such as D-dimers can be detected in the circulation.

Color Doppler ultrasound, conventional and MRI angiography, lineograms and echocardiography are the diagnostic means of imaging the occlusion of vessels.

Pulmonary Manifestation von Thrombophlebitis of proximal pulmonary arteries can be visualized by echocardiography and by CT scan; however, the specificity and sensitivity are low in detecting more distal clots. In such cases ventilation and perfusion scintigraphies are the recommended techniques for children. All techniques can be regarded as equally specific, sensitive and precise; their application, however, differs with respect to the region of interest, age and therapeutic options.

Imaging methods for thromboembolism in neonates and children. Assessment of prothrombotic risk factors is by no means suitable for diagnosing TE. It may possibly help to explain unusual manifestations of TE; however, the predictive power concerning outcome, thereby providing a basis for therapeutic and prophylactic decisions is still a matter of ongoing studies and debate.

Interpretation of laboratory data is strongly was mit Krampfadern Salbe zu tun dependent since normal ranges may differ considerably between newborns, young children and adolescents.

The most important factors involved in the genetic predisposition to thrombophilia are the factors of the coagulation cascade and in particular their natural inhibitors. It is not clear if genetic defects of fibrinolysis also contribute to the hypercoagulable state. Certain metabolic defects also cause thrombophilia. In addition to being the final substrate for thrombin, FI is also an acute-phase protein that may Manifestation von Thrombophlebitis to acquired thrombophilia and may also contribute to the risk of arterial TE.

This mutant correlates with slightly elevated FII levels, suggesting a quantitative contribution to thrombophilia, and is found at a frequency of 7. The derived relative risk for thrombosis is 2. FII A also seems to play a role in Manifestation von Thrombophlebitis stroke. Published data, however, Manifestation von Thrombophlebitis, do not give a clear picture. Due to its key position in platelet adhesion and aggregation Manifestation von Thrombophlebitis conditions of high shear forces, VWF plays a most important hemostatic role in arterial vessels and in the microcirculation.

An elevated level of VWF is an independent risk factor for myocardial infarction and stroke in adults. In the neonate, supra large VWF multimers, which are the most active in primary hemostasis, are more abundant than later in life and correlate with a very effective platelet dependent function of VWF in newborns. However, it is now clear that supra large VWF multimers are responsible for the life-threatening condition of TTP reviewed in The hemostatic process is tightly regulated by specific inhibitors that act on coagulation factors and on the factors of primary hemostasis.

Clinically, to date only the latter three are important, Manifestation von Thrombophlebitis. PC is activated to APC by thrombin, which changes its substrate specificity from FI to PC by being bound to thrombomodulin at the endothelial cell surface.

Severe PC deficiency as well as severe PS deficiency correlates with purpura fulminans, a life-threatening thromboembolic disorder of the microcirculation and larger vessels, Manifestation von Thrombophlebitis. Heterozygous deficiency of either inhibitor correlates with venous TE. PC also binds plasminogen activator inhibitor 1 PAI1 which then facilitates fibrinolysis. This dual function of PC suggests a central role in the regulation of thrombus formation.

Its action on thrombin is enhanced fold by heparin through an allosteric conformational change. In contrast, low-molecular-weight heparin makes AT more aFX specific, Manifestation von Thrombophlebitis. These effects are the basis for prophylactic or therapeutic anticoagulation by heparin.

Even mild hereditary deficiency of AT function may correlate with thrombophilia with a penetrance higher than in PC and PS deficiency. Its deficiency has clearly been assessed as playing the causative role in TTP.

Thrombosis of larger venous and arterial vessels has also been observed. In Manifestation von Thrombophlebitis, TTP is rare and seems more often inherited.

ADAMTS13 has been identified as a potent antithrombotic in an animal model, 30 which may be of future therapeutic interest. The activity of 5-methyl tetrahydrofolate-homocysteine-methyltransferase in turn depends on the availability of 5-methyl-tetrahydrofolate, regulated by 5, methyl tetrahydrofolate-reductase MTHFR.

Although repeatedly claimed in many studies, this variant does not seem to be an independent risk factor for TE, Manifestation von Thrombophlebitis. Lipoprotein a is considered a significant venous and arterial risk factor for TE in children.

Lp a has structural homology to plasminogen, suggesting a possible competitive mechanism of Lp a in fibrinolysis. However, the lack of correlation between severe plasminogen deficiency and TE speaks against this hypothesis. CVCs have become critically important as medical and supportive management of various diseases and have greatly improved quality of life. They bear two serious complications: TE is a well known complication in adult patients with cancer.

With the exception of acute lymphoblastic leukemia ALLthe knowledge about TE in childhood cancer is still limited. In contrast, brain tumors have a rather low incidence of thrombosis with or without CVC. TE in cancer is the result of complex interactions of a variety of factors such as the malignancy itself, chemotherapy and its side effects including infections or dehydration, CVCs, Manifestation von Thrombophlebitis, the unbalanced hemostatic system with predominant hypercoagulability as well as possible hereditary thrombophilia.

The impact of the different types of childhood malignancy on the hemostatic system is still not well understood, Manifestation von Thrombophlebitis.

APS is an antibody-mediated thrombophilic state characterized by specific clinical manifestations of venous, arterial or small vessel TE at any site as well as the presence of antiphospholipid antibodies APA in the blood. In addition to DVT, acute ischemic stroke or transient ischemic attack are characteristic. APS is often associated with a number of autoimmune disorders. APS is classified as primary and secondary; the clinical picture, however, is the same. Patients with no underlying disease are diagnosed as primary APS.

Secondary APS refers to patients with underlying autoimmune mainly rheumatologic disorders as well as viral and bacterial infections or cancer. All proposed pathophysiological mechanisms share the binding of the APA to anionic protein-phospholipid-complexes, leading to activation of endothelial cells, platelets and prothrombin, interference with natural inhibitory pathways and fibrinolysis, and disruption of the binding of annexin V to phospholipids coating the vascular system.

There have been recent reports on gene expression profiles to identify subtle distinctions in order to define the clinical relevance of different APA. In contrast, life-threatening TE including purpura fulminans may occur with varicella, which have been shown to have a increased prevalence of APA and associated PS deficiency. HIT-associated TE is mainly venous but arterial events may occur. To date, it remains an individual decision if and which antithrombotic prophylaxis should be offered considering additional and individual risk factors.

Irrespective of an underlying disease, every thromboembolic manifestation should be treated, aiming at the complete recanalization of the occluded Manifestation von Thrombophlebitis and stopping the thrombotic process. In the vast majority of cases thrombosis will resolve under heparin given for 5—14 days. Yet evidence shows no Manifestation von Thrombophlebitis in the antithrombotic efficacy. The following disadvantages should be considered: Advantages are easy subcutaneous administration once daily without need of venous access, predictable pharmacokinetics, minimal monitoring, minimized bleeding complications, Manifestation von Thrombophlebitis, reduced risk of HIT.

For the treatment duration of different sites, Manifestation von Thrombophlebitis, types and age Manifestation von Thrombophlebitis refer to references 53 The agent of choice is rt-PA, Manifestation von Thrombophlebitis. Streptokinase should not be used because of its allergic reactions. The use of urokinase at least in the USA is restricted for safety concerns. The established contraindications in adults apply for children as well but should be considered relative.
