Abstract After deep vein thrombosis (DVT) is diagnosed, prompt evaluation and therapeutic intervention are of paramount importance for improvement in patient-important outcomes. We systematically reviewed patient-important outcomes in patients with suspected DVT, including mortality, incidence of pulmonary embolism (PE) and DVT, major bleeding, intracranial hemorrhage, and postthrombotic sequelae. We searched the Cochrane Central Register of Controlled Trials, Ovid Medline, Embase for eligible studies, references lists of relevant reviews, registered trials, and relevant conference proceedings. Two investigators screened and abstracted data. Nine studies with 5126 patients were included for lower extremity DVT. Three studies with 500 patients were included for upper extremity DVT. Among patients with lower extremity DVT, 0.85% (95% confidence interval [CI], 0% to 2.10%) and 0% developed recurrent DVT and PE, respectively, at 3 months. Among patients with upper extremity DVT, 0.49% (95% CI, 0% to 1.16%) and 1.98% (95% CI, 0.62% to 3.33%) developed recurrent DVT and PE, respectively, at 3 months. No major bleeding events were reported for those anticoagulated, which is lower than in other systematic reviews. For both upper and lower extremity DVT, low pretest probability patients with a negative D-dimer had a comparable incidence of VTE at 3 months (∼1%) as patients with a negative ultrasound (US). At higher pretest probabilities, negative US testing with or without serial US appears to be the safer option. In this review, we summarized the outcomes of patients evaluated by various diagnostic pathways. In most instances, there was significant limitation due to small population size or lack of direct evidence of effects of using a specific pathway. This systematic review was registered at PROSPERO as CRD42018100502.

It is not well understood the efficacy and safety of primary deep vein thrombosis (DVT) prophylaxis of anticoagulants in patients with solid tumors. This systematic review and meta-analysis of randomized controlled trials (RCT) determines the relative ratio of primary DVT, survival rate and bleeding events among patients with solid tumors treated with anticoagulants or placebo. Comprehensive literature searches were conducted through the Pubmed, Ovid MEDLINE and EMBASE databases published from January 1st, 1993 to December 31st, 2015. Statistical analysis was performed by RevMan 5.0 software. For DVT events, therisk ratio in 16 trials between the prophylactic and control patients was statistically significant at 0.45 [0.36-0.58]; for major bleeding events, the risk ratio in 18 trials between the prophylactic and control patients was not statistically significant at 1.33 [0.99-1.79], while that in 15 trials with clinically relevant non-major bleeding was statistically significant at 1.83 [1.46-2.30]; the risk ratio for the mortality rate of patients with solid tumors in 16 trials was not statistically significant at 0.97 [0.93-1.02]. Inconclusion, the risk ratio in this meta-analysis showed a significantly reduced incidence of DVT with anticoagulant use. Treatment to patients who had solid tumors with prophylactic anticoagulants enhanced the incidence rate of non-major bleeding but has no significant impact on the incidence rate of major bleeding. No significant differences were found in the mortality outcomes between anticoagulant and non-anticoagulant groups.

Standard anticoagulant treatment alone for acute lower extremity deep vein thrombosis (DVT) is ineffective in eliminating thrombus from the deep venous system, with many patients developing postthrombotic syndrome (PTS). Because catheter-directed thrombolysis (CDT) can dissolve the clot, reducing the development of PTS in iliofemoral or femoropopliteal DVT. This meta-analysis compares CDT plus anticoagulation versus standard anticoagulation for acute iliofemoral or femoropopliteal DVT. Ten trials were included in the meta-analysis. Compared with anticoagulant alone, CDT was shown to significantly increase the percentage patency of the iliofemoral vein ( P < .00001; I2 = 44%) and reduce the risk of PTS ( P = .0002; I2 = 79%). In subgroup analysis of randomized controlled trials, CDT was not shown to prevent PTS ( P = .2; I2 = 59%). A reduced PTS risk was shown, however, in nonrandomized trials ( P < .00001; I2 = 47%). Meta-analysis showed that CDT can reduce severe PTS risk ( P = .002; I2 = 0%). However, CDT was not indicated to prevent mild PTS ( P = .91; I2 = 79%). A significant increase in bleeding events ( P < .00001; I2 = 33%) and pulmonary embolism (PE) ( P < .00001; I2 = 14%) were also demonstrated. However, for the CDT group, the duration of stay in the hospital was significantly prolonged compared to the anticoagulant group ( P < .00001; I2 = 0%). There was no significant difference in death ( P = .09; I2 = 0%) or recurrent venous thromboembolism events ( P = .52; I2 = 58%). This meta-analysis showed that CDT may improve patency of the iliofemoral vein or severe PTS compared with anticoagulation therapy alone, but measuring PTS risk remains controversial. However, CDT could increase the risk of bleeding events, PE events, and duration of hospital stay.

Abstract Upper extremity deep vein thrombosis (UEDVT) accounts for ≤10% of DVT and can be associated with morbidity and mortality. Accurate diagnosis and treatment are necessary for safe and effective patient management. We systematically reviewed the accuracy of D-dimer and duplex ultrasonography (US) for the evaluation of suspected first-episode UEDVT. We searched the Cochrane Central Register, OVID MEDLINE, EMBASE, and PubMed for eligible studies, reference lists of relevant reviews, registered trials, and relevant conference proceedings. We included prospective cross-sectional and cohort studies that evaluated test accuracy. Two investigators independently screened and collected data. The risk of bias was assessed using Quality Assessment of Diagnostic Accuracy Studies 2 and certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework. We pooled estimates of sensitivity and specificity. The review included 9 studies. The pooled estimates for D-dimer sensitivity and specificity were 0.96 (95% confidence interval [CI], 0.87-0.99) and 0.47 (95% CI, 0.43-0.52), respectively. The pooled estimates for duplex US sensitivity and specificity were 0.87 (95% CI, 0.73-0.94) and 0.85 (95% CI, 0.72-0.93), respectively. Certainty of evidence was moderate. In this review, we summarized the test accuracy (sensitivity and specificity) of D-dimer and duplex US for this indication. The sensitivity and specificity of the tests found in the present review should be considered in the context of whether they are used alone or in combination, which is dependent on the prevalence of disease in the population, the clinical setting in which the patient is being evaluated, cost, potential harms, and patient outcomes. This study was registered at PROSPERO as Systematic Review Registration Number CRD42018098488.

AbstractIsolated distal deep vein thrombosis (DVT) represents an important clinical problem but there is no consensus regarding its management. The aim of this review was to evaluate the safety, efficacy, and shorter versus longer duration of anticoagulation in patients with isolated distal DVT. A systematic search was conducted using MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systemic Reviews. Studies reporting rates of symptomatic pulmonary embolism (PE), recurrent DVT, proximal extension, and/or major bleeding were included. Fourteen studies (six randomized controlled trials, eight cohorts) involving 2,918 patients met the eligibility criteria (with a total of 13 meeting criteria for the meta-analysis). Compared with no anticoagulation, anticoagulation was associated with a significant reduction in proximal extension (odds ratio [OR]: 0.29; 95% confidence interval [CI]: 0.13–0.67; p < 0.004), recurrent DVT (OR: 0.16; 95% CI: 0.04–0.65; p = 0.01), and the composite end-point of proximal extension/PE (OR: 0.34; 95% CI: 0.16–0.72; p = 0.005); however, no significant differences in PE (OR: 0.47; 95% CI: 0.17–1.34; p = 0.16) or major bleeding (OR: 1.49; 95% CI: 0.33–6.86; p = 0.60) were observed. Anticoagulation for a longer duration (≥8 vs. ≤6 weeks) was associated with a significant reduction in proximal extension (OR: 0.23; 95% CI: 0.11–0.48; p < 0.001) but not for other outcomes.

Infection with SARS-CoV-2 leading to COVID-19 induces hyperinflammatory and hypercoagulable states, resulting in arterial and venous thromboembolic events. Deep vein thrombosis (DVT) has been well reported in COVID-19 patients. While most DVTs occur in a lower extremity, involvement of the upper extremity is uncommon. In this report, we describe the first reported patient with an upper extremity DVT recurrence secondary to COVID-19 infection.
