The assay is always used for its sensitivity (ie ability to rule out the diagnosis of dvt) rather than its specificity (ie ability to rule it in). This means that, in the appropriate clinical context, it is possible to definitively exclude a diagnosis of dvt and discharge a patient. It is not possible to definitively make the diagnosis: if the d-dimer assay is positive, further investigation is required. So the crucial question is: in which individual patients is the d-dimer test going to be useful in ruling out a diagnosis of dvt? The answer to this question depends on the pre-test probability of dvt which, in turn, is determined by clinical risk stratification. The major exception to this principle is pregnant / post-partum women in whom the risk of dvt and/or pe is universally high; there is no role for D-dimers in the investigation of these patients who, if the diagnosis is suspected, require definitive imaging. Another group of patients that are being increasingly recognised as being at high risk of dvt is the intravenous drug abuser; in particular, they are at risk of septic dvt.
This test is vulnerable to misuse (with potential patient harm) if the its role is misunderstood. The test detects fibrin fragments from clot degradation with a high sensitivity when used in appropriately risk-stratified patients with suspected vte: a negative d-dimer assay in this population results in a 3 month incidence of subsequent vte of approximately.5. However, its specificity is poor: D-dimer levels may be raised in any clinical condition in which clot turnover (clot formation and subsequent degradation) is increased. The assay also returns increasingly positive with advanced age, irrespective of the potential presence of any of these predisposing factors. A further important issue is the type of D-dimer assay used: a number of different D-dimer assays are in use throughout the uk, with varying levels of sensitivity and specificity.
Each test employs a different monoclonal antibody sensitive to a different part of the d-dimer molecule: D-dimer levels remain detectable for 7 days after initial clot formation. Testing outside this time may result in a false negative result. The presence of small clot load, particularly in the distal venous system, may provide too small a d-dimer level for a positive result. This may not be of major clinical concern, however, since there is no universal agreement whether isolated distal dvt requires treatment. It is critical that the result of a d-dimer assay is interpreted in light of the overall clinical picture and with knowledge of the locally used assays characteristics.

The wall thickens further over time, the likelihood of venous contractility increases, as does the tendency to chronic venous insufficiency causing long term morbidity and increased risk of recurrence. Regardless of the many described risk factors, only a few have been selected for formal risk stratification in proven clinical studies (see below). Symptoms and signs are variable at presentation and no single symptom or sign is pathognomonic of dvt. Presenting features are related to the effects of outflow obstruction and local inflammation. However, adaptation of venous collaterals and variable levels of inflammation mean that the degree of thrombus formation (ie the clot load ) is frequently unrelated to the clinical findings.
Typical features related to the presenting complaint elicited in the history and examination: A careful history searching for relevant risk factors is crucial in determining the most appropriate strategy for investigation; risk factors have been described in the previous section. These are combined with clinical features on presentation to complete a formal risk stratification of patients with suspected dvt (see below). There are many other conditions that present with localised pain or oedema in the lower limbs which may be confused with dvt (see box). A carefully taken history will be helpful:. Determine if onset was sudden (musculoskeletal) or gradual (dvt, arterial insufficiency). Examination will help to exclude cellulitis (fever, skin demarcation or arterial insufficiency (pallor of the leg, absent pulses, sensory changes). Following history, evaluation of risk factors and clinical examination, the d-dimer test is the most immediately available investigation used in the diagnostic strategy for dvt in the.

Rudolf Virchow 2 reported the relationship between venous stasis, a hypercoaguable state and endothelial vessel wall damage and risk of thrombosis the so called Virchow Triad : There exists equilibrium between clot formation and clot breakdown; a combination of risk factors may tip this equilibrium. Virchows Triad forms the basis for the pathophysiology of dvt. A combination of the triad of factors is required for thrombosis to twins form one factor in isolation is not usually sufficient. The presence of each constituent of Virchows triad is, in turn, determined by various factors (Fig 1) which collectively determine risk of dvt in any individual patient. The presence and combination of these factors may trigger the pathophysiological process that results in local cytokine production and facilitation of leukocyte adhesion to the endothelium. Whilst the relative contribution of each factor has been long debated, the process reflects ontstoken the dynamic equilibrium between the pro- and anti-thrombotic tendencies in the deep venous system. The standard treatment strategies for dvt are determined by these factors and are centred on anticoagulation and the prevention of venous stasis. If the condition goes unrecognised over time, the thrombus subsequently organises and inflammatory cells infiltrate into the clot resulting in intimal thickening.
Deep vein Thrombosis: History and
The early diagnosis of dvt and pe in symptomatic patients significantly reduces adverse outcome. The initial presentation of a dvt is usually with leg pain and/or swelling. Clearly this has a wide differential diagnosis and presents the clinician with a diagnostic challenge this challenge and the subsequent treatment of dvt is the subject of this session. Dvt typically presents in the lower limb, although it can also werkende rarely occur in the upper limb. The venous anatomy of the leg predisposes itself to the formation of thrombosis: low flow areas such as soleal sinuses, valve pockets and at venous confluences are common sites of clot formation. Clearly the lower limbs are also more prone to the dependent effects of gravity than the upper limbs. This clot can then propagate proximally into the popliteal, femoral and iliac veins.
Authors: James Simon Dunn, jason m kendall /. Editor: gavin Lloyd reviewer: Sarah Hickin codes: cap20, hap19/. Published: 20/19/2017 review Date: 20/19/2020, deep vein Thrombosis (DVT) is defined as the presence of a blood clot (thrombus) in the deep venous system. Dvt and Pulmonary embolism (PE) form the spectrum of venous thromboembolic disorders (VTE) and are associated with significant mortality and morbidity. Pe, whilst it can occur de novo, is most commonly secondary to dvt. It zelf occurs at a rate of 100-200 per 100,000 of the general population, with.5 5 of the population being affected at some point in their lifetime. Up to 50 of dvt patients will suffer long-term consequences including chronic pain, pigmentation or ulceration. Prevention of vte by using effective thromboprophylaxis in patients admitted to hospital is a major healthcare priority. This aspect of vte is not covered in this session.
