Lungenembolie Standard Wells' Criteria for DVT - MDCalc
Pulmonary embolism PE is a blockage of an artery in the lungs by a substance that has traveled from elsewhere in the body through the bloodstream embolism. PE usually results from a blood clot in the leg that travels to the lung. Efforts to prevent PE include beginning to move as soon as possible after surgery, lower leg exercises during periods of sitting, and the use of blood thinners after some types of surgery. Pulmonary emboli affect aboutpeople each year in Europe.
Symptoms of pulmonary embolism are typically sudden in onset and may include one or many of the following: On physical examination, the lungs are usually normal. Occasionally, a pleural friction rub may be audible over the affected area of the lung mostly in PE with infarct. A pleural effusion is sometimes present that is exudative, detectable by decreased percussion note, audible breath sounds, and vocal resonance. As smaller pulmonary emboli Lungenembolie Standard to lodge in Lungenembolie Standard peripheral areas without collateral circulation they are more likely to cause lung infarction and small effusions both of which are painfulbut not hypoxia, dyspnea or hemodynamic instability such as tachycardia.
Larger PEs, which tend to lodge centrally, typically cause dyspnea, hypoxia, Lungenembolie Standard, low blood pressureLungenembolie Standard, fast heart rate and faintingbut are often painless because there is no lung infarction due to collateral circulation. The classic presentation for PE with pleuritic pain, dyspnea and tachycardia is likely caused by a large fragmented embolism causing both large and small PEs, Lungenembolie Standard.
Thus, small PEs are often missed because they cause pleuritic pain alone without any other Lungenembolie Standard and large PEs often missed because they are painless and mimic other conditions often causing ECG changes and small rises in troponin and BNP levels. PEs are sometimes described as massive, submassive and nonmassive depending on the clinical signs and symptoms. Although the exact definitions of these are unclear, an accepted definition of massive PE is one in which there is hemodynamic instability such as sustained low blood pressure, slowed heart rateor pulselessness.
The conditions are generally regarded as a continuum termed venous thromboembolism VTE. The development of thrombosis is classically due to a group of causes named Virchow's triad alterations in blood flow, factors in the vessel wall and factors affecting the properties of the blood. Often, Lungenembolie Standard, more than one risk factor is present.
After a first PE, Lungenembolie Standard, the search for secondary causes is usually brief. Only when a second PE occurs, Lungenembolie Standard, and especially when this happens while still under anticoagulant therapy, a further search for Lungenembolie Standard conditions is undertaken. This will include testing "thrombophilia screen" for Factor V Leiden Lungenembolie Standardantiphospholipid antibodies, Lungenembolie Standard C and S and antithrombin levels, and later prothrombin mutation, MTHFR mutation, Factor VIII concentration and rarer inherited coagulation abnormalities, Lungenembolie Standard.
In order to diagnose a pulmonary embolism, a review of clinical criteria to determine the need Lungenembolie Standard testing is recommended. If there are concerns this is followed by testing to determine a likelihood of being able to confirm a diagnosis by imaging, followed by imaging if other tests have shown that there is a likelihood of a PE diagnosis, Lungenembolie Standard.
The medizinische Geschichte der Chirurgie mit Krampfadern of PE is based primarily on validated clinical criteria combined with selective Gebärmutterhals-Varizen because the typical clinical presentation shortness of breathchest pain cannot be Massage Fußbad und Krampfadern differentiated from other causes of chest pain and shortness of breath.
The decision to Lungenembolie Standard medical imaging is based on clinical reasoning, that is, Lungenembolie Standard, Varizen der oberen Extremität medical historysymptoms and findings on physical examinationfollowed by an assessment of clinical probability.
The most Lungenembolie Standard used method to predict clinical probability, the Wells score, is a clinical prediction rulewhose use Lungenembolie Standard complicated by multiple versions being available.
InPhilip Steven Wellsinitially developed a prediction rule based on a literature search to predict the Lungenembolie Standard of PE, based on clinical criteria, Lungenembolie Standard. There are additional prediction rules for PE, such as the Geneva rule. More importantly, the Lungenembolie Standard of any rule is associated with reduction in recurrent thromboembolism.
Traditional interpretation   . Alternative interpretation  . The pulmonary embolism rule-out criteria PERC helps assess people in Krampfadern Pilates pulmonary embolism is suspected, Lungenembolie Standard, but unlikely. Unlike the Wells score and Geneva scorewhich are clinical prediction rules intended to risk stratify people with suspected PE, the PERC rule is designed to rule out risk of PE in people when the physician has already stratified them into a low-risk category, Lungenembolie Standard.
People in this low risk category without any of these criteria may undergo no further Lungenembolie Standard testing for PE: The rationale behind this decision is that further testing specifically CT angiogram of the chest may cause more harm from radiation exposure and contrast dye than the risk of PE. In people with a low or moderate suspicion of PE, a normal D-dimer level shown in a blood test is enough to exclude the possibility of thrombotic PE, with a three-month risk of thromboembolic events being 0.
In other words, a positive D-dimer is not synonymous with PE, but a negative D-dimer is, with a good degree of certainty, an indication of absence of a PE. When a PE is being suspected, several blood tests are done in order to exclude important secondary causes of PE. This includes a full blood countclotting status PTaPTTTTLungenembolie Standard, and some screening tests erythrocyte sedimentation raterenal functionliver enzymeselectrolytes, Lungenembolie Standard.
If one of these is abnormal, further investigations might be Lungenembolie Standard. In typical people who are not known to be at high risk of PE, imaging is helpful to confirm or exclude a diagnosis of PE after simpler first-line tests are used.
CT pulmonary angiography is the recommended first line diagnostic imaging test in most people. Historically, the gold standard for diagnosis was pulmonary angiographybut this has fallen into disuse with the Lungenembolie Standard availability of non-invasive techniques.
CT pulmonary angiography CTPA is a pulmonary angiogram obtained using computed tomography CT with radiocontrast rather than right heart catheterization, Lungenembolie Standard. Its advantages are clinical Lungenembolie Standard, its non-invasive nature, its greater availability to people, and the possibility of identifying other lung disorders from the differential diagnosis in case there is no pulmonary embolism.
On CT scanpulmonary emboli can be classified according to level along the arterial tree. CT pulmonary angiography showing a "saddle embolus" at the bifurcation of the main pulmonary artery and thrombus burden in the lobar arteries on both sides. Assessing the accuracy of CT pulmonary angiography is hindered by the rapid changes in the number of rows of detectors available in multidetector CT MDCT machines.
However, this study's results may be biased due to possible incorporation bias, since the CT scan was Lungenembolie Standard final diagnostic tool in people with pulmonary embolism.
The authors noted that a negative single slice CT scan is insufficient to rule out pulmonary embolism on its own. This study noted that additional testing is necessary when the clinical probability is inconsistent Lungenembolie Standard the imaging results, Lungenembolie Standard. It is particularly useful in people who have an allergy to iodinated contrastimpaired renal function, or are pregnant due to its lower radiation exposure as compared to CT.
Tests that are frequently done that are not sensitive for PE, but can be diagnostic. The primary use of the ECG is to rule out Lungenembolie Standard causes of chest pain. While certain ECG changes may occur with PE, none are specific enough to confirm or sensitive enough to rule out the diagnosis.
The most commonly seen signs in the ECG are sinus tachycardiaright axis deviation, and right bundle branch block. In massive and submassive PE, dysfunction of the right side of the heart may be seen on echocardiographyLungenembolie Standard, an indication that the pulmonary artery is severely obstructed and the right ventriclea low-pressure pump, is unable to match the pressure.
Some studies see below suggest that this finding may be an indication for thrombolysis. Lungenembolie Standard every person with a suspected pulmonary embolism requires an echocardiogram, but elevations in cardiac troponins or brain natriuretic peptide may indicate heart Lungenembolie Standard and warrant an echocardiogram,  and be important in prognosis.
The specific appearance of the right Lungenembolie Standard on echocardiography is referred to Lungenembolie Standard the McConnell's sign. This is the finding of akinesia of the mid-free wall but a normal motion of the apex. Ultrasound of the heart showing signs of PE . Pulmonary embolism may be preventable in those with risk factors.
People admitted to hospital may receive preventative medication, including unfractionated heparinlow molecular weight heparin LMWHor fondaparinuxand anti-thrombosis stockings to reduce the risk of a DVT in the leg that could dislodge and migrate to the lungs. Following the completion of warfarin in those with prior PE, long-term aspirin is useful to prevent recurrence, Lungenembolie Standard. Anticoagulant therapy is the Lungenembolie Standard of treatment.
Acutely, Lungenembolie Standard treatments, such as oxygen or analgesiamay be required. Lungenembolie Standard are often admitted to hospital in the early stages of treatment, Lungenembolie Standard, and tend to remain under inpatient care until the INR has reached therapeutic levels. Increasingly, however, low-risk cases are managed at home in a fashion already common in the treatment of DVT.
Usually, anticoagulant therapy is the mainstay of treatment. Unfractionated heparin UFHlow molecular weight heparin LMWHor fondaparinux is administered initially, while warfarinLungenembolie Standard, acenocoumarolLungenembolie Standard, or phenprocoumon therapy is commenced this may take several days, usually while the patient is in the hospital. LMWH may reduce bleeding among people with pulmonary embolism as compared to UFH according to a systematic review of randomized controlled trials by the Cochrane Collaboration.
There was no difference in overall mortality between participants treated with LMWH and those treated with unfractionated heparin. Warfarin therapy often requires a frequent dose adjustment and monitoring of the international normalized ratio INR.
In patients with an underlying malignancy, Lungenembolie Standard, therapy with a course of LMWH is favored over warfarin; it Lungenembolie Standard continued for six months, at which point a decision should be reached whether ongoing treatment is required, Lungenembolie Standard.
Similarly, pregnant women are often maintained on low molecular Lungenembolie Standard heparin until at least six weeks after delivery to avoid the known teratogenic effects of warfarin, especially in the early stages of pregnancy.
Warfarin therapy is usually continued for 3—6 months, or "lifelong" if there have been previous DVTs or PEs, Lungenembolie Standard, or none of the usual risk factors is present. An abnormal D-dimer level at the Lungenembolie Standard of treatment might signal the need for continued treatment among patients with a first unprovoked pulmonary embolus.
In this situation, it is the best available treatment in those without contraindications and is supported by clinical guidelines. Catheter-directed thrombolysis CDT is a new technique found to be relatively safe and effective for massive PEs. This involves accessing the venous system by placing a catheter into a vein in the groin and guiding it through the veins by using fluoroscopic imaging until it is located next to the PE in the lung circulation.
Medication that breaks up blood clots is released through the catheter so that its highest concentration is directly next to the pulmonary embolus. CDT is performed by interventional radiologistsand in medical centers that offer CDT, it may be offered as a first-line treatment.
The use of thrombolysis in Lungenembolie Standard PEs is still debated. There are two situations when an inferior vena cava filter is considered advantageous, and those are if anticoagulant therapy is contraindicated e.
Inferior vena cava filters should be removed as soon as it becomes safe to start using anticoagulation. The long-term safety profile of permanently leaving a filter inside the body is not known.
Surgical management of acute pulmonary embolism pulmonary thrombectomy Lungenembolie Standard uncommon and has largely been abandoned because of poor long-term outcomes. However, Lungenembolie Standard, recently, it has gone through a resurgence with the revision of Lungenembolie Standard surgical technique and is thought to benefit certain people.
Pulmonary emboli occur in more thanpeople in the United States each year. There are several markers used for risk stratification and these are also independent predictors of adverse outcome, Lungenembolie Standard.
These include hypotension, cardiogenic shock, Lungenembolie Standard, syncope, evidence of right heart Lungenembolie Standard, and elevated cardiac enzymes. Prognosis depends on Welche Übung kann bei Krampfadern sein amount of lung that is affected and on the co-existence of other medical conditions; chronic embolisation to the lung can lead to pulmonary hypertension.
After a massive PE, the embolus must Lungenembolie Standard resolved somehow if the patient is to survive. In thrombotic PE, the blood clot may be broken down by fibrinolysisLungenembolie Standard, or it may be organized and recanalized so that a new channel forms through the clot.
Blood flow is restored most rapidly in the first day or two after a PE. There is controversy over whether small subsegmental PEs need treatment at all  and some evidence exists that patients with subsegmental PEs may do well without treatment.
Once anticoagulation is stopped, the risk of a fatal pulmonary embolism is 0, Lungenembolie Standard. This figure comes from a trial published in by Barrit and Jordan,  which compared anticoagulation against placebo for the management of PE. Barritt and Jordan performed their Lungenembolie Standard in the Bristol Royal Infirmary in
