Project description:ObjectiveTo evaluates the efficacy and safety of rivaroxaban versus aspirin in prevention of venous thromboembolism (VTE) following total hip (THA) or knee arthroplasty (TKA) or hip fracture surgery.MethodsMajor databases were systematically searched for all relevant studies published in English up to October 2020. The meta-analysis was conducted using RevMan 5.3 software.ResultsIn total, 7 studies were retrieved which contained 5133 patients. Among these patients, 2605 patients (50.8%) received rivaroxaban, whereas 2528 patients (49.2%) received aspirin. There were no statistical difference between aspirin and rivaroxaban for reducing VTE (RR = 0.75, 95% CI 0.50-1.11, I2 = 36%, p = 0.15), major bleeding (RR = 0.94, 95% CI 0.45-2.37, I2 = 21%, p = 0.95), and all-cause mortality (RR = 0.88, 95% CI 0.12-6.44, I2 = 0%, p = 0.90) between the two groups. Compared with aspirin, rivaroxaban significantly increased nonmajor bleeding (RR = 1.29, 95% CI 1.05-1.58, I2 = 0%, p = 0.02).ConclusionThere was no significant difference between aspirin and rivaroxaban in prevention of venous thromboembolism following total joint arthroplasty or hip fracture surgery. Aspirin may be an effective, safe, convenient, and cheap alternative for prevention of VTE. Further large randomized studies are required to confirm these findings.

Project description:Venous thromboembolism (VTE) has been identified as a major public health issue. Postbariatric body contouring surgery represents a major challenge for VTE prophylaxis due to the presence of multiple risk factors and broad areas of dissection that potentially increase the risk of postoperative bleeding.To define current VTE prophylaxis practices among surgeons of the American Society of Plastic Surgeons, performing postbariatric body contouring surgery in the United States.A total of 4081 surveys were sent to registered members of the American Society of Plastic Surgeons by e-mail. We received 596 (14.6%) responses.A total of 596 surgeons returned completed surveys, with 83% of respondents in private practice and 17% in academic practice. Deep venous thrombosis (DVT) was reported by 40% surgeons, pulmonary embolism (PE) by 34%, and 7% had at least 1 patient having died of a postoperative PE. About 39% to 48% participant surgeons reported providing no chemoprophylaxis to their postbariatric body contouring patients. The most common reason for not using routine prophylaxis was the concern for bleeding (84%), followed by lack of evidence specific to plastic surgery practice (50%). Academic surgeons were more likely to provide chemoprophylaxis when compared with those in nonacademic practice (P < 0.05).For postbariatric body contouring surgery, DVT has occurred in over one-third of plastic surgeons' practices with 7% of surgeons reporting a patient death from PE. A substantial proportion of surgeons performing postbariatric body contouring are not using chemoprophylaxis due to bleeding risk and perceived lack of evidence. VTE prophylaxis in postbariatric body contouring remains a topic that deserves further study.

Project description:BackgroundVenous thromboembolism (VTE) is a common source of perioperative morbidity and mortality.ObjectiveThese evidence-based guidelines from the American Society of Hematology (ASH) intend to support decision making about preventing VTE in patients undergoing surgery.MethodsASH formed a multidisciplinary guideline panel balanced to minimize bias from conflicts of interest. The McMaster University GRADE Centre supported the guideline-development process, including performing systematic reviews. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess evidence and make recommendations, which were subject to public comment.ResultsThe panel agreed on 30 recommendations, including for major surgery in general (n = 8), orthopedic surgery (n = 7), major general surgery (n = 3), major neurosurgical procedures (n = 2), urological surgery (n = 4), cardiac surgery and major vascular surgery (n = 2), major trauma (n = 2), and major gynecological surgery (n = 2).ConclusionsFor patients undergoing major surgery in general, the panel made conditional recommendations for mechanical prophylaxis over no prophylaxis, for pneumatic compression prophylaxis over graduated compression stockings, and against inferior vena cava filters. In patients undergoing total hip or total knee arthroplasty, conditional recommendations included using either aspirin or anticoagulants, as well as for a direct oral anticoagulant over low-molecular-weight heparin (LMWH). For major general surgery, the panel suggested pharmacological prophylaxis over no prophylaxis, using LMWH or unfractionated heparin. For major neurosurgery, transurethral resection of the prostate, or radical prostatectomy, the panel suggested against pharmacological prophylaxis. For major trauma surgery or major gynecological surgery, the panel suggested pharmacological prophylaxis over no prophylaxis.

Project description:PurposeVenous thromboembolism (VTE) after bariatric surgery is a significant cause of morbidity and mortality. Current modalities of thromboprophylaxis include subcutaneous injection of unfractionated or low-molecular-weight heparin (LMWH), pneumatic compression, elastic stockings, and inferior vena cava filters. Despite universal agreement on the need for thromboprophylaxis, no clear consensus has been reached regarding the best regimen and treatment duration of bariatric surgery.MethodsFrom April, 2009 to December, 2011, we performed 200 bariatric surgery (191 with primary intent, 9 with revisional intent). There was no history of VTE prior to surgery. Clexane therapy was done with 4000 U SQ once daily for 2 weeks to the day before surgery. Development of VTE was assessed by direct interview, physical examination in out-patient clinic, and phone calls to patients for history taking if needed. The history taking was presented in questionnaire format. The patients were asked to state their symptoms of VTE by answering the questionnaire. The patients were followed up for a minimum of 6 months after surgery to determine the incidence of clinical VTE.ResultsTwo-week Clexane therapy was completed in 193 patients. Clexane was stopped in 5 due to surgical related complications (4 bleeding, 1 reoperation due to leak), in 2 due to Clexane related complications (1 epistaxis, 1 metrorrhagia). Follow-up of out-patient clinic were 68%, those who could follow up by telephone were 89%. There was no evidence of VTE.ConclusionA 2-week VTE prophylaxis regimen using LMWH is simple, effective and associated with a low incidence of complications.

Project description:Albeit it does not have the highest venous thromboembolism (VTE) incidence compared to other neoplasms, breast cancer contributes to many VTE events because it is the most diagnosed tumor in women. We aim to analyze the occurrence and timing of VTE during the follow-up of patients who underwent breast surgery, the possible correlated factors, and the overall survival. This retrospective study included all female patients diagnosed with mammary pathology and surgically treated in our clinic between January 2002 and January 2012. Of 5039 women who underwent breast surgery, 1056 were found to have no evidence of malignancy, whereas 3983 were diagnosed with breast cancer. VTE rate resulted significantly higher in patients with invasive breast cancer than in women with benign breast disease or carcinoma in situ. Invasive cancers other than lobular or ductal were associated with a higher VTE rate. In addition, chronic hypertension, high BMI, cancer type, and evidence of metastasis turned out to be the most significant risk factors for VTE in women who underwent breast surgery. Moreover, VTE occurrence significantly impacted survival in invasive breast cancer patients. Compared to women with benign mammary pathology, VTE prevalence in women with breast cancer is significantly higher. The knowledge about the risk factors of VTE could be helpful as prognostic information, but also to eventually target preventive treatment strategies for VTE, as far as the co-existence of invasive breast cancer and VTE has a significantly negative impact on survival.

Project description:BackgroundModern diagnostic strategies for venous thromboembolism (VTE) incorporate pretest probability (PTP; prevalence) assessment. The ability of diagnostic tests to correctly identify or exclude VTE is influenced by VTE prevalence and test accuracy characteristics.ObjectiveThese evidence-based guidelines are intended to support patients, clinicians, and health care professionals in VTE diagnosis. Diagnostic strategies were evaluated for pulmonary embolism (PE), deep vein thrombosis (DVT) of the lower and upper extremity, and recurrent VTE.MethodsThe American Society of Hematology (ASH) formed a multidisciplinary panel including patient representatives. The McMaster University GRADE Centre completed systematic reviews up to 1 October 2017. The panel prioritized questions and outcomes and used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to assess evidence and make recommendations. Test accuracy estimates and VTE population prevalence were used to model expected outcomes in diagnostic pathways. Where modeling was not feasible, management and accuracy studies were used to formulate recommendations.ResultsTen recommendations are presented, by PTP for patients with suspected PE and lower extremity DVT, and for recurrent VTE and upper extremity DVT.ConclusionsFor patients at low (unlikely) VTE risk, using D-dimer as the initial test reduces the need for diagnostic imaging. For patients at high (likely) VTE risk, imaging is warranted. For PE diagnosis, ventilation-perfusion scanning and computed tomography pulmonary angiography are the most validated tests, whereas lower or upper extremity DVT diagnosis uses ultrasonography. Research is needed on new diagnostic modalities and to validate clinical decision rules for patients with suspected recurrent VTE.

Project description:BackgroundDespite an increasing incidence of venous thromboembolism (VTE) in pediatric patients in tertiary care settings, relatively few pediatric physicians have experience with antithrombotic interventions.ObjectiveThese guidelines of the American Society of Hematology (ASH), based on the best available evidence, are intended to support patients, clinicians, and other health care professionals in their decisions about management of pediatric VTE.MethodsASH formed a multidisciplinary guideline panel that included 2 patient representatives and was balanced to minimize potential bias from conflicts of interest. The McMaster University GRADE Centre supported the guideline-development process, including updating or performing systematic evidence reviews (up to April of 2017). The panel prioritized clinical questions and outcomes according to their importance for clinicians and patients. The panel used the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach, including GRADE Evidence-to-Decision frameworks, to assess evidence and make recommendations, which were subject to public comment.ResultsThe panel agreed on 30 recommendations, covering symptomatic and asymptomatic deep vein thrombosis, with specific focus on management of central venous access device-associated VTE. The panel also addressed renal and portal vein thrombosis, cerebral sino venous thrombosis, and homozygous protein C deficiency.ConclusionsAlthough the panel offered many recommendations, additional research is required. Priorities include understanding the natural history of asymptomatic thrombosis, determining subgroup boundaries that enable risk stratification of children for escalation of treatment, and appropriate study of newer anticoagulant agents in children.

Project description:Venous thromboembolism is a well-established complication of total hip and knee arthroplasty and hip fracture surgery. Clinical practice guidelines have been proposed to help clinicians provide prophylaxis against this risk. However, most guidelines reference data that are becoming outdated because of new advances in perioperative protocols. Recent data would suggest that aspirin may be appropriate for most patients after total hip and knee replacement and a more potent chemoprophylaxis for higher risk patients. Low-molecular-weight heparin remains the recommended choice after hip fracture surgery, although there is a paucity of recent literature in this patient population. There are randomized trials currently underway in the arthroplasty population that may guide clinicians in the appropriate choice of chemoprophylaxis. These studies should inform updates to the current clinical practice guidelines.

Project description:The Korean venous thromboembolism (VTE) registry, which was initiated by the Working Parties of Korean Society on Thrombosis and Hemostasis, and the Korean Society of Hematology, is a web-based multicenter registry (http://kdvt.chamc.co.kr) for recruiting consecutive VTE patients. The aim of the registry is to prospectively collect data on the epidemiology and clinical outcomes of VTE from a large, unselected cohort of patients, and to provide data on the true incidence and management of VTE in the real-world. By the end of 2007, the starting year of the registry, 840 patients were registered. By the end of 2008, 1,121 were registered, with 1,289 by the end of 2009, and 1,463 by April 2010 from 11 hospitals. The first report on the epidemiologic characteristics of 596 consecutive VTE patients was released in October 2007.

Project description:Background and purpose - New oral anticoagulants have been developed to prevent venous thromboembolism (VTE) after knee or hip arthroplasty. Although there have been several network meta-analyses (NMA) to compare different regimens, an NMA including 2 different enoxaparin doses and edoxaban has not been performed. Methods - Standard NMA for fondaparinux, dabigatran, rivaroxaban, apixaban, edoxaban, and enoxaparin was performed. Outcome variables included a composite of total VTE and major/clinically relevant bleeding. The rank probabilities of each treatment outcome were summarized by the surface under the cumulative ranking curve. Results - Fondaparinux, rivaroxaban, and apixaban were associated with a reduced risk of VTE compared with enoxaparin, while dabigatran was not. None of these 3 drugs increased bleeding compared with enoxaparin 30?mg twice daily. However, fondaparinux and rivaroxaban increased bleeding compared with enoxaparin 40?mg once daily, while apixaban did not. Apixaban was even associated with decreased major/clinically relevant bleeding compared with enoxaparin 30?mg twice daily or 40?mg once daily. When edoxaban was included in the NMA, edoxaban decreased VTE and did not increase bleeding compared with enoxaparin. Interpretation - A higher efficacy of fondaparinux and rivaroxaban compared with enoxaparin was associated with increased bleeding tendency, while apixaban was superior to enoxaparin regarding both efficacy and safety. A clustered ranking plot showed that apixaban might be the most preferred regarding efficacy and safety. However, our results were driven by indirect statistical inference and were limited by the heterogeneity of the bleeding outcome definitions, drug initiation and continuation, and different surgery types.
