Project description:Chronic upper extremity deep vein thrombosis (UEDVT) and superior vena cava syndrome (SVCS) are important and underdiagnosed entities that are associated with significant morbidity, and both are becoming increasingly common due to the use of indwelling catheters and implantable central venous access devices. Currently, as many as 25% of patients with an indwelling catheter are diagnosed with chronic UEDVT or venous stenosis. SVCS is most commonly seen in the setting of malignancy, especially lung cancer and lymphoma. Endovascular management of chronic UEDVT and SVCS is accepted as an important first-line treatment given its high overall success rate and low morbidity as compared with medical and surgical treatments. In this article, the indications for treatment, complications, and success rates of the endovascular management of UEDVT and SVCS are reviewed. Relevant findings on presentation and physical exam as well as various imaging modalities and imaging findings are evaluated. Details of preprocedure evaluation, relevant anatomy, and avoidance of potential complications are discussed.

Project description:Approximately 10% of all deep vein thromboses occur in the upper extremity, and that number is increasing due to the use of peripherally inserted central catheters. Sequelae of upper extremity deep vein thrombosis (UEDVT) are similar to those for lower extremity deep vein thrombosis (LEDVT) and include postthrombotic syndrome and pulmonary embolism. In addition to systemic anticoagulation, there are multiple interventional treatment options for UEDVT with the potential to reduce the incidence of these sequelae. To date, there have been no randomized trials to define the optimal management strategy for patients presenting with UEDVT, so many conclusions are drawn from smaller, single-center studies or from LEDVT research. In this article, the authors describe the evidence for the currently available treatment options and an approach to a patient with acute UEDVT.

Project description:Lower extremity deep vein thrombosis (DVT) is a common illness with an annual incidence of 1 per 1000 adults. The major long-term complication of DVT is post-thrombotic syndrome (PTS) which occurs in up to 60% of patients within 2 years of an episode of DVT.We aim to evaluate the outcomes of catheter-directed treatment (CDT) for symptomatic acute or subacute lower extremity DVT.A retrospective 12-year study was conducted on the outcomes of CDT on 54 consecutive patients who presented with acute or subacute lower extremity DVT to our hospital.Descriptive summary statistics and the Chi-square test were used to measure the outcomes of CDT.Grade 3 thrombolysis was achieved in 25 (46.3%) patients, grade 2 thrombolysis in 25 (46.3%) patients, and grade 1 thrombolysis in 4 (7.4%) patients. Significant recanalization (grade 2 or 3 thrombolysis) was possible in 50 (92.6%) patients. There was no statistically significant difference in the percentage of significant recanalization that could be achieved between patients who underwent CDT before and after 10 days. There was no significant difference between the thrombolysis achieved between urokinase and r-tPA. PTS was seen in 33% of the patients. Major complications were seen in 5.5% of the patients.CDT is a safe and effective therapeutic technique in patients with acute and subacute lower extremity DVT, if appropriate patient selection is made.

Project description:Purpose:Deep vein thrombosis (DVT) is the third most common cause of cardiovascular morbidity and mortality. Anticoagulation has been the primary treatment modality for acute DVT. However, catheter-directed thrombolysis (CDT) has recently become widely accepted as an additional therapy to anticoagulation. We assessed comparative outcomes in patients with acute DVT who underwent anticoagulation therapy alone (ACA) group and those treated with CDT group. Materials and Methods:We retrospectively reviewed medical records of 149 patients with DVT from January 2011 to December 2015. We compared patients who received ACA group (n=120) and those who received CDT plus anticoagulation (CDT group, n=29). We analyzed the prevalence of lesions, thrombus removal rate in each lesion, and recurrence-free rate between the two groups. Results:We found thrombus involvement in a total of 281 lesions in the ACA group and 85 lesions in the CDT group. For the distribution of lesions in each group, those in the femoral vein accounted for 34.2% of all lesions and those in the popliteal vein accounted for 31.7%. During follow-up, the overall thrombus removal rate was 91.1% in the ACA group and 87.0% in the CDT group (P=0.273). The recurrence-free rate was higher in the CDT group in a log-rank test; however, there was no statistically significant difference between the two groups (P=0.594). Conclusion:According to our results, there was no significant difference in thrombus removal and recurrence-free rates between the CDT and ACA groups. ACA still has an important role in the treatment of DVT.

Project description:BackgroundDeep vein thrombosis (DVT) of the lower extremity (LE) might lead to pulmonary embolism (PE) and post-thrombolytic syndrome (PTS). Recently, percutaneous endovenous intervention (PEVI) has been advocated for early removal of thrombus clot and restoration of venous patency. This study aims to review the safety and efficacy outcomes of PEVI versus anticoagulation in the treatment of acute LE-DVT.MethodsWe searched the databases of PubMed, Embase, and the Cochrane Library for randomized controlled trials (RCTs) comparing catheter-directed thrombolysis (CDT) and/or pharmacomechanical thrombectomy (PMT) versus anticoagulation for acute proximal LE-DVT, published before August 2022. Efficacy outcomes were PTS and venous patency. Safety outcomes included recurrent thromboembolism, bleeding complications, and PE.ResultsOverall, 1,266 patients were included from 6 RCTs. The overall risk of bias was small due to enrolled high-quality RCTs. Compared to anticoagulation, PEVI moderately reduced PTS incidence [odds ratio (OR) 0.47, 95% confidence interval (CI) 0.23-0.99], obviously inhibited moderate-to-severe PTS (OR 0.60, 95% CI: 0.40-0.88), significantly decreased PE (OR 0.16, 95% CI: 0.05-0.48), and substantially increased venous patency (OR 7.95, 95% CI: 1.00-63.16). There was no significant difference in recurrent thromboembolism between PEVI and anticoagulation (OR 0.76, 95% CI: 0.34-1.73). Bleeding events did not differ statistically between PEVI and anticoagulation (OR 1.36, 95% CI: 0.87-2.11). We conducted single-arm meta-analysis of the PEVI or anticoagulation. Pooled proportion of PTS was less after PEVI (0.295, 95% CI: 0.123-0.505) than after anticoagulation (0.459, 95% CI: 0.306-0.616). Pooled proportion of moderate-to-severe PTS was lower after PEVI (0.098, 95% CI: 0.033-0.191) than after anticoagulation (0.183, 95% CI: 0.126-0.247). Pooled proportion of PE was smaller after PEVI (0.006, 95% CI: 0.00-0.020) as compared to anticoagulation (0.075, 95% CI: 0.038-0.122). Pooled proportion of recurrent thromboembolism was similar between PEVI (0.095, 95% CI: 0.054-0.146) and anticoagulation (0.124, 95% CI: 0.061-0.206). Pooled proportion of bleeding was not different statistically between PEVI (0.026, 95% CI: 0.00-0.131) and anticoagulation (0.008, 95% CI: 0.00-0.094).ConclusionsPEVI, consisting of PMT and/or CDT, is an extremely effective and feasible approach for patients with acute LE-DVT. In comparison to therapeutic anticoagulation, PEVI restores venous patency, inhibits the PTS development, reduces the PE occurrence, does not markedly increase the bleeding risk, but does not reduce recurrent thromboembolism.

Project description:BackgroundIdiopathic upper extremity deep vein thrombosis (UEDVT) management is controversial and ranges from anticoagulation alone to the addition of further interventions such as thrombolysis and decompressive surgery.ObjectivesThe objective of this systematic review was to assess the effects of anticoagulation alone compared to anticoagulation with additional interventions such as thrombolysis or decompressive surgery on the incidence of recurrent UEDVT and post-thrombotic syndrome (PTS) in patients with idiopathic UEDVT (including those associated with the oral contraceptive pill).Patients/methodsA systematic search was conducted for studies which focused on acute UEDVT treatment defined as therapies starting within 4 weeks of symptom onset. We limited studies to those that recruited 10 or more subjects and involved at least 6 weeks to 12 months anticoagulation alone or together with additional interventions with at least 6-month follow-up. Primary outcomes were symptomatic recurrent radiologically confirmed UEDVT and PTS. Secondary outcomes were symptomatic venous thromboembolism, bleeding and mortality.ResultsWe found seven studies which reported recurrent UEDVT rates and five that reported PTS rates. All studies were retrospective or cross-sectional. None compared anticoagulation alone to anticoagulation with additional intervention. Study heterogeneity precluded meta-analysis and risk of bias was moderate to serious. Recurrent UEDVT occurred in 0% to 12% post-anticoagulation alone and 0% to 23% post-additional interventions. PTS rates varied from 4% to 32% without severe PTS. Only limited studies reported on our secondary outcomes.ConclusionThere is limited evidence behind idiopathic UEDVT management. Prospective comparative studies in this area are essential.

Project description:Our understanding of postthrombotic syndrome (PTS) predictors in children is evolving. The present study aimed to investigate differences in patient- and deep vein thrombosis (DVT)-related characteristics between central venous catheter (CVC)-related and non-CVC-related thrombosis in children, as well as early PTS predictors. Children aged 0 to 18 years were prospectively recruited ≥6 months after imaging-proven upper- or lower-extremity DVT. PTS was measured using CAPTSure. Early predictors included age at DVT diagnosis, DVT symptoms, DVT burden, and days on therapeutic anticoagulation within 30 days post-DVT diagnosis. Analysis of predictors was stratified by CVC-related and non-CVC-related thrombosis. Generalized estimating equations were used for data analyses. In total, 313 DVT-affected extremities of 256 patients were assessed; 275 (88%) DVT cases were CVC related. Patients with non-CVC-related thrombosis were older (median age, 5.8 years; 25th-75th percentile, 4.9-6.4 years vs 3.5 months; 25th-75th percentile, 0.7-18.7 months; P < .001) and more likely to have thrombophilia (64% vs 22%; P < .001) and obesity (30% vs 13%; P = .01) than patients with CVC-related thrombosis. CAPTSure scores were 9.5 points higher (standard error, 3.0; P = .02) in the non-CVC-related thrombosis stratum. Age at the time of DVT predicted PTS in both strata; DVT burden and time from DVT diagnosis to PTS assessment predicted PTS in CVC-related thrombosis. In sum, PTS severity was higher in non-CVC-related vs CVC-related thrombosis. Increasing age at the time of DVT was associated with higher PTS severity. DVT burden and time from DVT diagnosis to PTS assessment were significant PTS predictors in CVC-related thrombosis, indicating that long-term follow-up of these children is important.

Project description:BackgroundThe ATTRACT trial (Acute Venous Thrombosis: Thrombus Removal with Adjunctive Catheter-Directed Thrombolysis) previously reported that pharmacomechanical catheter-directed thrombolysis (PCDT) did not prevent postthrombotic syndrome (PTS) in patients with acute proximal deep vein thrombosis. In the current analysis, we examine the effect of PCDT in ATTRACT patients with iliofemoral deep vein thrombosis.MethodsWithin a large multicenter randomized trial, 391 patients with acute deep vein thrombosis involving the iliac or common femoral veins were randomized to PCDT with anticoagulation versus anticoagulation alone (No-PCDT) and were followed for 24 months to compare short-term and long-term outcomes.ResultsBetween 6 and 24 months, there was no difference in the occurrence of PTS (Villalta scale ≥5 or ulcer: 49% PCDT versus 51% No-PCDT; risk ratio, 0.95; 95% CI, 0.78-1.15; P=0.59). PCDT led to reduced PTS severity as shown by lower mean Villalta and Venous Clinical Severity Scores ( P<0.01 for comparisons at 6, 12, 18, and 24 months), and fewer patients with moderate-or-severe PTS (Villalta scale ≥10 or ulcer: 18% versus 28%; risk ratio, 0.65; 95% CI, 0.45-0.94; P=0.021) or severe PTS (Villalta scale ≥15 or ulcer: 8.7% versus 15%; risk ratio, 0.57; 95% CI, 0.32-1.01; P=0.048; and Venous Clinical Severity Score ≥8: 6.6% versus 14%; risk ratio, 0.46; 95% CI, 0.24-0.87; P=0.013). From baseline, PCDT led to greater reduction in leg pain and swelling ( P<0.01 for comparisons at 10 and 30 days) and greater improvement in venous disease-specific quality of life (Venous Insufficiency Epidemiological and Economic Study Quality of Life unit difference 5.6 through 24 months, P=0.029), but no difference in generic quality of life ( P>0.2 for comparisons of SF-36 mental and physical component summary scores through 24 months). In patients having PCDT versus No-PCDT, major bleeding within 10 days occurred in 1.5% versus 0.5% ( P=0.32), and recurrent venous thromboembolism over 24 months was observed in 13% versus 9.2% ( P=0.21).ConclusionsIn patients with acute iliofemoral deep vein thrombosis, PCDT did not influence the occurrence of PTS or recurrent venous thromboembolism. However, PCDT significantly reduced early leg symptoms and, over 24 months, reduced PTS severity scores, reduced the proportion of patients who developed moderate-or-severe PTS, and resulted in greater improvement in venous disease-specific quality of life.Clinical trial registrationURL: https://www.clinicaltrials.gov .

Project description:Small studies have suggested differences in demographics and outcomes between left- and right-sided deep vein thrombosis (DVT), and also unilateral versus bilateral DVT. We investigated the clinical presentation and outcomes of patients with DVT based on thrombus sidedness. The authors used the data from the Registro Informatizado Enfermedad TromboEmbólica (RIETE) database (2001-2016) to identify patients with symptomatic proximal lower-extremity DVT. Main outcomes included cumulative 90-day symptomatic pulmonary embolism (PE) and 1-year mortality. Overall, 30,445 patients were included. The majority of DVTs occurred in the left leg (16,421 left-sided, 12,643 right-sided, and 1,390 bilateral; p < 0.001 for chi-squared test comparing all three groups). Comorbidities were relatively similar in those with left-sided and right-sided DVT. Compared with those with left-sided DVT, patients with right-sided DVT had higher relative frequency of PE (26% versus 23%, p < 0.001) and 1-year mortality (odds ratio [OR]: 1.08; 95% confidence interval [CI]: 1.00-1.18). This difference in mortality did not persist after multivariable adjustment (OR: 1.01; 95% CI: 0.93-1.1). Patients with bilateral DVT had a greater burden of comorbidities such as heart failure, and recent surgery compared with those with unilateral DVT (p < 0.001), and higher relative frequency of PE (48%), and 1-year mortality (24.1%). Worse outcomes in patients with bilateral DVT were attenuated but persisted after multivariable adjustment for demographics and risk factors (OR: 1.64; 95% CI: 1.43-1.87). Patients with bilateral DVT had worse outcomes during and after discontinuation of anticoagulation. There is a left-sided preponderance for proximal lower-extremity DVT. Compared with those with left-sided DVT, patients with right-sided DVT have slightly higher rates of PE. Bilateral DVT is associated with markedly worse short-term and 1-year outcomes.
