deep vein thrombosis ppt

[18][106] A review of prior imaging is considered worthwhile, as is "reviewing baseline blood test results including full blood count, renal and hepatic function, PT and APTT. The most common form of venous thrombosis is a deep vein thrombosis (DVT), when a blood clot forms in the deep veins of the leg. VTE has a strong genetic component, accounting for approximately 50 to 60% of the variability in VTE rates. [167][168], Methods to observe DVT by ultrasound were established in the 1960s. What can RIETE teach … After deep vein thrombosis (DVT) is diagnosed, prompt evaluation and therapeutic intervention are of paramount importance for improvement in patient-important outcomes. Deep vein Thrombosis (DVT) (1) - Deep vein thrombosis (DVT) is a serious condition that occurs when a blood clot forms in a vein located deep inside your body. 3 0 obj [29] Those with significant VTE risk factors[p] undertaking long-haul travel are suggested to use either graduated compression stockings or LMWH for VTE prevention. [4] VTE occurs in association with hospitalization or nursing home residence about 60% of the time, active cancer about 20% of the time, and a central venous catheter or transvenous pacemaker about 9% of the time. [49], Treatment for acute leg DVT can continue at home instead of one being hospitalized. %���� To provide an evidence-based approach to treatment of patients presenting with deep vein thrombosis (DVT). [65][79], DVT often develops in the calf veins and "grows" in the direction of venous flow, towards the heart. [87] With this prediction rule, three points or less means a person is at low risk for DVT. [80] When DVT does not grow, it can be cleared naturally and dissolved into the blood (fibrinolysis). [1][5] A Wells score of two or more means DVT is considered "likely" (about a 28% chance), while those with a lower score are considered "unlikely" to have DVT (about a 6% chance). The score is used in suspected first lower extremity DVT (without any PE symptoms) in primary care and outpatient settings, including the emergency department. pΚ�lJ�e6�'C>�\�U��GV���ZW�ҺE��j���|��u�խ�5gGs��g4o�8��B��B$���w���[�:w��2�a��L�m{/s�ma},��w��j��ح��R���� �R�׽fR�bI� u7��t$���b�}��+�7pe�x�}~�'�`�56�R4?�^��e��(N���vy�(���&�}/��. •Deep Vein Thrombosis, or DVT, occurs when a large blood clot forms in a vein in your body, usually the leg. Description. Deep vein thrombosis can cause leg pain or swelling, but may occur without any symptoms. [29] Critically ill hospitalized patients are recommended to either receive unfractionated heparin or low-molecular weight heparin instead of foregoing these medicines. [5], An unprovoked VTE might signal the presence of an unknown cancer, as it is an underlying condition in up to 10% of unprovoked cases. Oral contraceptives[b] and hormonal replacement therapy increase the risk through a variety of mechanisms, including altered blood coagulation protein levels and reduced fibrinolysis. For example, in cases of isolated distal DVT, ultrasound surveillance (a second ultrasound after 2 weeks to check for proximal clots), might be used instead of anticoagulation. ), Doppler ultrasonography showing absence of flow and hyperechogenic content in a clotted femoral vein (labeled subsartorial[j]) distal to the branching point of the deep femoral vein. [11], Provoked DVTs occur in association with acquired risk factors, such as surgery, oral contraceptives, trauma, immobility, obesity, or cancer; cases without acquired states are called unprovoked or idiopathic. [24] Inactivity and immobilization contribute to venous stasis, as with orthopedic casts,[31] paralysis, sitting, long-haul travel, bed rest, hospitalization,[28] and in survivors of acute stroke. WebMD explains what puts you at risk and offers ways to prevent it. A superficial venous thrombosis … [10] Additionally, approximately 5% of people have been identified with a background genetic risk comparable to the factor V Leiden and prothrombin G20210A mutations. [174] VTE follow-up costs at three months, six months, and a year are about $5,000, $10,000, and $33,000 respectively; in Europe, the three and six-month figures are about €1,800 and €3,200. 2. A blood clot is a clump of blood that is in a gelatinous, solid state. [7], Blood has a natural propensity to clot when blood vessels are damaged (hemostasis) to minimize blood loss. She started to receive an ultrasound to look for DVT in the legs, prompting her to express dissatisfaction to the medical staff that they were not looking for clots where she had symptoms (her lungs), and they were not yet treating her presumed PE. Symptoms of DVT may include the following: 1. [citation needed][quantify] Statins have also been investigated for their potential to reduce recurrent VTE rates, with some studies suggesting effectiveness. [28][24] These three deficiencies increase the risk of VTE by about 10 times. [28] Minor injuries,[29] lower limb amputation,[30] hip fracture, and long bone fractures are also risks. Those with another thrombophilia but no family or personal history of VTE were suggested for watchful waiting only. Depending on how likely you are to have a blood clot, your doctor might suggest tests, including: 1. [102] Thrombophilia test results rarely play a role in the length of treatment. Clinical symptoms of PE as the primary manifestation As many as 46% with patients with classic symptoms have negative venograms,[2] and as many as 50% of those with image-documented venous thrombosis lack specific symptoms. [143] Meanwhile, almost 1% of those aged 85 and above experience VTE each year. National Institute for Health and Care Excellence. [27] The New York Times described a "furious battle" among the three makers of these drugs "for the prescription pads of doctors".[172]. While there are a number of risk factors for developing a DVT, two of the most common are experiencing an injury to your lower body and having surgery that involves your hips or legs. [85], A clinical probability assessment using the Wells score (see dedicated column in the table below) to determine if a potential DVT is "likely" or "unlikely" is typically the first step of the diagnostic process. For other uses, see, Formation of a blood clot (thrombus) in a deep vein, Structural representations of the backbone of heparins (, "It is important to note that smoking is not an independent risk factor, although it increases the risk for cancers and other comorbidities and works synergistically with other independent risk factors.". [21] Around 56% of those with proximal DVT also have PE, although a chest CT is not needed simply because of the presence of DVT. An elevated level[h] can result from plasmin dissolving a clot—or other conditions. [168] It was not until 1950 that this framework was cited as Virchow's triad,[167] but the teaching of Virchow's triad has continued in light of its utility as a theoretical framework and as a recognition of the significant progress Virchow made in expanding the understanding of VTE. They use the term VTE because the two conditions are very closely related. [98] Periodic INR monitoring is not necessary when first-line direct oral anticoagulants are used. [18] Signs and symptoms alone are not sufficiently sensitive or specific to make a diagnosis, but when considered in conjunction with pre-test probability, can help determine the likelihood of DVT. [14] However, available data has been historically dominated by European and North American populations,[15] and Asian and Hispanic individuals have a lower VTE risk than whites or Blacks. Both DVT and PE are considered as part of the same overall disease process, venous thromboembolism (VTE), which can occur as DVT or PE with or without DVT. Anyone can get DVT at any time, but there are risk factors that can increase your chances of developing this condition. [2] Providing anticoagulation, or blood-thinning medicine, is the typical treatment after patients are checked to make sure they are not subject to bleeding. [29], DVT is most frequently a disease of older age that occurs in the context of nursing homes, hospitals, and active cancer. Symptoms can include pain, swelling, redness, and enlarged veins in the affected area, but some DVTs have no symptoms. [1] The most common life-threatening concern with DVT is the potential for a clot (or multiple clots) to detach from the veins (embolize), travel through the right side of the heart, and become stuck in arteries that supply blood to the lungs. [30] Chemotherapy treatment also increases risk. It contains only objective criteria but requires obtaining a D-dimer value. You'll also have a physical exam so that your doctor can check for areas of swelling, tenderness or discoloration on your skin. [18] In those with an annual risk of VTE in excess of 9%, as after an unprovoked episode, extended anticoagulation is a possibility. DVT results from conditions that impair venous return, lead to endothelial injury or dysfunction, or cause hypercoagulability.

[27], About 1.5 out of 1000 adults a year have a first VTE in high-income countries,[141][142] and about 5–11% of people will develop VTE in their lifetime. [88], CT scan venography, MRI venography, or a non-contrast MRI are also diagnostic possibilities. [96] The benefit of taking warfarin declines as the duration of treatment extends,[97] and the risk of bleeding increases with age. [13] Whole-leg ultrasound is the option that does not require a repeat ultrasound,[13] but proximal compression ultrasound is frequently used because distal DVT is only rarely clinically significant. [106] A 2018 study associated IVC filter placement with a 50% reduction in PE, a 70% increase in DVT, and an 18% increase in 30 day mortality when compared to no IVC placement. [5] A minority of upper extremity DVTs are due to Paget–Schroetter syndrome, also called effort thrombosis, which occurs in 1–2 people out of 100,000 a year, usually in athletic males around 30 years of age or in those who do significant amounts of overhead manual labor. 4 0 obj When compared to this clot, clots that instead obstruct the common femoral vein cause more severe effects due to impacting a significantly larger portion of the leg. [126] Following major orthopedic surgery, a blood thinner or aspirin is typically paired with intermittent pneumatic compression, which is the preferred mechanical prophylaxis over graduated compression stockings. A D-dimer test can also be used to assist with excluding the diagnosis or to signal a need for further testing. Homozygous carriers of factor V Leiden or prothrombin G20210A with no personal or family history of VTE were suggested for watchful waiting during pregnancy and LMWH or a VKA for six weeks after childbirth. [1] A thorough clinical assessment is needed and should include a physical examination, a review of medical history, and universal cancer screening done in people of that age. Similar Images . A wandlike device (transducer) placed over the part of your body where there's a clot sends sound waves into the area… [16][17] Warfarin is taken to maintain an international normalized ratio (INR) of 2.0–3.0, with 2.5 as the target. Deep vein thrombosis occurs when a blood clot (thrombus) forms in one or more of the deep veins in the body, usually in the legs. [106] However, a 2020 NICE review found "little good evidence" for their use. The Wells score as displayed here is the more recent modified score, which added a criteron for a previous documented DVT and increased the time range after a surgery to 12 weeks from 4 weeks. [177] As an example, if 300,000 symptomatic DVT patients were treated at costs averaging $20,000 annually, that would cost $6 billion a year. <>>> "[95] Anticoagulation alone is suggested over thrombectomy. [3] VTE is the third most common cause of death from cardiovascular disease, with the top two causes being coronary heart disease and ischemic stroke. Those with another thrombophilia and a family history but no previous VTE were suggested for watchful waiting during pregnancy and LMWH or—for those without protein C or S deficiency—a VKA. [7], The risk of VTE is increased in pregnancy by about five times[40][128] because of a more hypercoagulable state, a likely adaptation against fatal postpartum hemorrhage. Deep vein thrombosis (DVT) commonly affects the lower limb, with clot formation beginning in a deep calf vein and propagating proximally. The most common cause of death associated with DVT is when a blood clot (or multiple clots) detach from the veins (embolize), travel through the right side of the heart, and become stuck in pulmonary arteries that supply deoxygenated blood to the lungs for oxygenation. For populations in China, Japan, and Thailand, deficiences in protein S, protein C, and antithrombin predominate. [1][5] The numerical result (possible score −2 to 9) is most commonly grouped into either "unlikely" or "likely" categories. [138][3] VTE recurrence in those with prior DVT is more likely to recur as DVT than PE.

For example, DVT and PE played a role in rapper Heavy D's death at age 44. PE, and can be fatal. [51] Other associated conditions include heparin-induced thrombocytopenia,[52] thrombotic storm,[53] catastrophic antiphospholipid syndrome,[54] paroxysmal nocturnal hemoglobinuria,[55] nephrotic syndrome,[12] chronic kidney disease,[56] HIV,[57] polycythemia vera,[31] intravenous drug use,[58] and smoking. [39] Genetic factors that increase the risk of VTE include deficiencies of three proteins that normally prevent blood from clotting—protein C, protein S, and antithrombin. [36] Cancers of the bone, ovary, brain, pancreas, and lymphomas are especially associated with increased VTE risk. [83] Platelets and white blood cells are also components. A 2019 study published in Nature Genetics reported more than doubling the known genetic loci associated with VTE. The circumstances in which an index VTE event occurred are crucial when personalized VTE recurrence risk is assessed. Preventive efforts following low-risk surgery include early and frequent walking. [19] Reductions in fibrinolysis or increases in coagulation can increase the risk of DVT.[19]. [165][166], In 1856, German physician and pathologist Rudolf Virchow published his analysis after the insertion of foreign bodies into the jugular veins of dogs, which migrated to the pulmonary arteries. Presentation Summary : Thrombosis and embolism . [24] Inflammation is associated with VTE,[g] and white blood cells play a role in the formation and resolution of venous clots. [21] In those unlikely to have DVT, a diagnosis is excluded by a negative D-dimer blood test. EPIDEMIOLOGY & DEMOGRAPHICS
Annual incidence in urban population is 1.6 cases/1000 persons. A blood clot is when blood congeals together and creates a gel-like, semi-solid state inside of the vein. [18] Upper extremity DVT occurs in the arms or the base of the neck. If the thrombus breaks off (it embolizes) and flows towards the lungs, it can become a pulmonary embolism (PE), a blood clot in the lungs. [81] The blood flow pattern in the valves can cause low oxygen concentrations in the blood (hypoxemia) of a valve sinus. [121], Anticoagulation, which increases the risk of bleeding, is sometimes used indefinitely (lifelong treatment) in those with a high-risk for recurrence. This causes a blood clot, in this case in a deep vein, which prevents deoxygenated blood from returning to the heart. She was first diagnosed while First Lady in 1998 and again in 2009. Download Deep Vein Thrombosis PPt Comments. [8] In orthopedic surgery, venous stasis can be temporarily provoked by a cessation of blood flow as part of the procedure. [2, 3] No single physical finding or comb… 2 0 obj %PDF-1.5 [4], In North American and European populations, around 4–8% of people have a thrombophilia,[40] most commonly factor V leiden and prothrombin G20210A. [179], "DVT" redirects here. Frequent walking, calf exercises, maintaining a healthy body weight, 1.0–1.8 out of 1,000 people per year with European ancestry, Active cancer (treatment within last 6 months or palliative), Calf swelling ≥ 3 cm compared to asymptomatic calf (measured 10 cm below, Swollen unilateral superficial veins (non-varicose, in symptomatic leg), Unilateral pitting edema (in symptomatic leg), Localized tenderness along the deep venous system, Recently bedridden ≥ 3 days, or major surgery requiring regional or general anesthetic in the past 12 weeks, Positive D-dimer (≥ 0.5 mcg/mL or 1.7 nmol/L), This page was last edited on 6 January 2021, at 14:12. Leg pain - Occurs in 50% of patients but is nonspecific 3. [140] In upper extremity DVT, annual VTE recurrence is about 2–4%. [32] Conditions that involve compromised blood flow in the veins are May–Thurner syndrome, where a vein of the pelvis is compressed, and venous thoracic outlet syndrome, which includes Paget–Schroetter syndrome, where compression occurs near the base of the neck. [1][116] As such, if someone develops a PE despite being anticoagulated, care should be given to optimize anticoagulation treatment and address other related concerns before considering the placement of a IVC filter. [147] Non-O blood type is present in around 50% of the general population and varies with ethnicity, and it is present in about 70% of those with VTE. Riskier surgeries generally prevent VTE with a blood thinner or aspirin combined with intermittent pneumatic compression. [18] In most suspected cases, DVT is ruled out after evaluation,[21] and symptoms are more often due to other causes, such as ruptured Baker's cyst, cellulitis, hematoma, lymphedema, and chronic venous insufficiency. [3], The mechanism of clot formation typically involves some combination of decreased blood flow rate, increased tendency to clot, and injury to the blood vessel wall. By Dr S Homathy. [9] Other related causes include activation of immune system components, the state of microparticles in the blood, the concentration of oxygen, and possible platelet activation. These parenteral (non-oral) medicines include low-molecular-weight heparin, fondaparinux, and unfractionated heparin. The Dutch Primary Care Rule has also been validated for use. The term 'thrombophilia' as used here applies to the five inherited abnormalities of antithrombin, protein C, protein S, factor V, and prothrombin, as is done elsewhere. [99], The duration of anticoagulation therapy (whether it will last 4 to 6 weeks,[5] 6 to 12 weeks, 3 to 6 months,[18] or indefinitely) is a key factor in clinical decision making. [175] Post-thrombotic syndrome is a significant contributor to DVT follow-up costs. – PowerPoint PPT presentation. Despite it being relatively rare, it is a leading cause of maternal morbidity and mortality. [37], D-dimers are a fibrin degradation product, a natural byproduct of fibrinolysis that is typically found in the blood. [3], During pregnancy and after childbirth, acute VTE occurs about 1.2 of 1000 deliveries. [11], The causes of arterial thrombosis, such as with heart attacks, are more clearly understood than those of venous thrombosis. [76][77][f] It is a particularly severe form of acute, proximal, and occlusive DVT.
The risk of recurrent thromboembolism is higher among men than women
Annual … [94] Catheter-directed thrombolysis against iliofemoral DVT has been associated with a reduction in the severity of post-thrombotic syndrome at an estimated cost-effectiveness ratio of about $138,000[n] per gained QALY. [98] After surgery, a provoked proximal DVT or PE has an annual recurrence rate of only 0.7%. [165] Yet, in the mid 1990s, contrast venography and impedance plethysmography were still described as common. This translates to 2 … [10][39] Having a non-O blood type roughly doubles VTE risk. You’ve selected "Deep Vein Thrombosis (DVT)." Thrombosis is the formation of a … Add to Likebox #138801634 - Hand stain Deep red blood clot in hand Symptoms of hemorrhage.. Ultrasound. After feeling the sudden onset of a PE symptom, shortness of breath, she told her nurse and requested a CT scan and an IV heparin drip, all while gasping for air. [4] Genetic factors include non-O blood type, deficiencies of antithrombin, protein C, and protein S and the mutations of factor V Leiden and prothrombin G20210A. [165] In 1271, DVT symptoms in the leg of a 20-year-old male were described in a French manuscript, which has been cited as the first case or the first Western reference to DVT. [101] For example, antithrombin deficiency, a strong or moderately strong risk factor, carries an annual risk of VTE of only 0.8–1.5%;[40] as such, asymptomatic individuals with thrombophilia do not warrant long-term anticoagulation. Some oral medicines are sufficient when taken alone, while others require the use of an additional parenteral blood thinner. [72][73] DVT below the popliteal vein, a proximal vein behind the knee, is classified as distal[64] and has limited clinical significance compared to proximal DVT. [5][93] Although, those with isolated distal DVT at a high-risk of VTE recurrence are typically anticoagulated as if they had proximal DVT. About 10-20% of thromboses extend proximally, and a further 1-5% go on to develop fatal pulmonary embolism. [78] It can occur in the arm but more commonly affects the leg. (The common femoral vein is distal to the external iliac vein. G J Geersing, N P A Zuithoff, C Kearon, D R Anderson, A J ten Cate-Hoek, J L Elf, S M Bates, A W Hoes, R A Kraaijenhagen, R Oudega, R E G Schutgens, S M Stevens, S C Woller, P S Wells, K G M Moons. [94] Thus, anticoagulation is the preferred treatment for DVT. What Is Deep Vein Thrombosis (DVT)? It is life-threatening, limb-threatening, and carries a risk of venous gangrene. endobj [67][68] An initial episode of DVT is called incident and any subsequent DVT is termed recurrent. Appropriate antithrombotic measures can reduce this complication. [104] Graduated compression stockings—which apply higher pressure at the ankles and a lower pressure around the knees[95] can be trialed for symptomatic management of acute DVT symptoms, but they are not recommended for reducing the risk of post-thrombotic syndrome,[94] as the potential benefit of using them for this goal "may be uncertain". [151] Head injuries prompting brain bleeds are of particular concern. [135] However, graduated compression stockings are not suggested for long-haul travelers (>4 hours) without risk factors for VTE. [18][94] When warfarin is initiated for VTE treatment, a 5-day minimum of a parenteral anticoagulant[l] together with warfarin is given, which is followed by warfarin only therapy. [158][161], Patients with a history of DVT might be managed by primary care, general internal medicine, hematology, cardiology, vascular surgery, or vascular medicine. In the postpartum, placental tearing releases substances that favor clotting. 2 3 4 The rate of involvement of particular sites varies: distal veins 40%, popliteal 16%, femoral 20%, common femoral 20%, and iliac veins … [12][13] VTE becomes much more common with age. [5] In contrast, those with proximal DVT should receive at least 3 months of anticoagulation. For a customized experience, choose the option below that best applies to you: Learning about DVT I recently had a deep vein thrombosis, and I need more information about the condition and treatment options. DVT is the primary cause of pulmonary embolism. [41] Individuals without O blood type have higher blood levels of von Willebrand factor and factor VIII than those with O blood type, increasing the likelihood of clotting. In isolated distal DVT, the profile of risk factors appears distinct from proximal DVT. 1 0 obj [d], Some risk factors influence the location of DVT within the body. [133][134] Graduated compression stockings have sharply reduced the levels of asymptomatic DVT in airline passengers, but the effect on symptomatic DVT, PE, or mortality is unknown, as none of the individuals studied developed these outcomes. [122] If someone decides to stop anticoagulation after an unprovoked VTE instead of being on lifelong anticoagulation, aspirin can be used to reduce the risk of recurrence,[123] but it is less effective at preventing VTE than anticoagulation.
