“…Proximal DVT is often associated with acute PE. [19][20][21][22][23] Embolic risk is low in calf-only DVT, but elevated in calf DVT with proximal (thigh) involvement. 19 DVT in the right iliac vein is easily torn off and PE easily occurs because the right iliac vein is not compressed, unlike the left iliac vein.…”

Background There are few data on the differences between deep vein thrombosis (DVT) with pulmonary embolism (PE) (Group A) and without PE (Group B), and no recent data on the incidence of PE and DVT in Japan. Methods and ResultsThe symptoms and findings of the lower extremities and risks for venous thromboembolism were compared between Groups A and B, and the numbers of new patients with PE and those with DVT in 2006 were calculated. DVT was found equally in left and right legs in Group A, but more frequently in left legs than in right legs in Group B. Proximal thrombus was more frequent in Group A than in Group B, and the number of cases of symptoms resulting from DVT was less in Group A than in Group B. Proximal DVT, DVT in the right leg, no symptoms, and younger age were related to the presence of PE. The calculated number of new patients with PE per year was 7,864 (3,492 cases in 1996), and that with DVT per year was 14,674. Conclusion DVT in patients with PE and those without PE differed in the site and symptoms. The calculated number of new patients with PE per year doubled in 1 decade in Japan.

“…Of asymptomatic surgical patients, 15% have been shown to have evidence of PE on lung scans [24]. In patients with known DVT but without symptoms suggesting PE, 40% to 60% have lung scan or angiogram findings suggesting PE [19][20][21]; this has led some authors to propose that all patients diagnosed with DVT have a baseline ventilation-perfusion (V/Q) scan [18,21]. Because the risk of recurrent VTE is low in patients adequately treated and because of the unclear clinical significance of these abnormal V/ Q scans, other authors do not think that baseline lung scans are indicated for all patients diagnosed with DVT [20,[44][45][46].…”

“…A high incidence of asymptomatic PE has been shown in patients with deep venous thrombosis (DVT) [18][19][20][21][22], suggesting that PE may be common and only infrequently may lead to death. Although some studies have found mortality rates from untreated PE ranging from 25% to 30%, these studies involved patients with other comorbidities that likely contributed to the adverse outcomes [17,23,24].Other studies involving patients without coexisting cardiopulmonary disease have found that mortality even with untreated or recurrent PE was significantly lower [22,[24][25][26][27].…”

“…Some investigators feel that small emboli must be considered the harbinger of future larger emboli and, therefore, clinically important. But other evidence suggests that small peripheral emboli might have little consequence for patients without underlying cardiopulmonary disease and no evidence of peripheral deep vein thrombosis [37,59]. In a study by HULL et al [60], patients with nondiagnostic V9/Q9 lung scans, who had no substantial cardiac or pulmonary disease, received no anticoagulants unless there was evidence of deep vein thrombosis at impedance plethysmography.…”

Diagnostic strategies for suspected pulmonary embolism

Pulmonary embolism often remains a difficult diagnosis for the clinician, particularly in patients with comorbidity factors. This is in contrast with the availability of effective treatment, which should be prescribed as soon as possible.To date, there is still no ideal diagnostic test that is accurate, safe, readily available and cost-effective.Recent technical advances in computed tomography, magnetic resonance imaging and laboratory findings have raised new possibilities in the diagnosis of pulmonary embolism.This review covers the performance of different diagnostic tests, and focuses on the advantages and limitations of single diagnostic tests and the clinical usefulness of these tests in diagnostic strategies.
