ObjectivesTo systematically review the efficacy and safety of new oral anticoagulants (Apixaban, Rivaroxaban, or Dabigatran) after joint replacement.MethodsCNKI, WanFang Data, VIP, CBM, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) on new oral anticoagulants after joint replacement from inception to October, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies, and then meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 13 RCTs were included. The results of meta-analysis showed that compared to Enoxaparin, the new oral anticoagulant significantly reduced the incidence of asymptomatic deep vein thrombosis (DVT) (RR=0.60, 95%CI 0.46 to 0.78, P<0.000 1) and symptomatic DVT (RR=0.40, 95%CI 0.28 to 0.58, P<0.000 1), while the incidence of symptomatic pulmonary embolism (PE) during treatment (RR=0.91, 95%CI 0.59 to 1.39, P=0.65) and mortality (RR=1.00, 95%CI 0.40 to 1.76, P=0.99) were not reduced. Major bleeding (RR=1.05, 95%CI 0.81 to 1.35, P=0.72) and clinically relevant non-major bleeding events (RR=0.99, 95%CI 0.73 to 1.33, P=0.94) with new oral anticoagulants were not statistically different from Enoxaparin.ConclusionsCurrent evidence shows that new oral anticoagulants can effectively reduce the incidence of DVT in patients after joint replacement without increasing the risk of adverse events such as bleeding. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusions.
ObjectiveTo summarize the applied research status on the evaluation tools of patient-reported outcome at home and abroad in patients with venous thromboembolism (VTE). MethodBy searching and analyzing the literatures, this paper summarized the concept, evaluation tools and application status of patient-reported outcome in the field of VTE. ResultsThe patient-reported outcomes can more comprehensively and accurately evaluate the disease burden and treatment effect of patients with venous thromboembolism, and can help doctors better understand patients' needs and guide individualized treatment and rehabilitation plans. ConclusionsPatient-reported outcome has a broad application prospect in the field of venous thromboembolism. Further promotion and application of patient-reported outcome can promote the development of medical research and provide reference guidelines for improving the management of patients with venous thromboembolism.
Objective Pulmonary thromboembolism ( PTE) is associated with various risk factors which existed in multidisciplinary patients. It is necessary to know what the role of pulmonologists in the diagnosis of PTE. Methods Data were collected from thirteen general hospitals in Guangxi. Hospital records of PTE cases from1995 to 2007 were retrospectively analyzed. The rates of PTE to inpatients between the respiratory departments and other departments or between different periods were compared. Results The rates of PTE of inpatients in respiratory departments ( 1. 55‰, 170/109 577) was higher than that in other departments ( 0. 03‰, 69/2 322 944) , P lt; 0. 001. Compared to that of 1995-2001, the rate of PTE of inpatients in the respiratory departments in the last 6 years increased by 3220. 22% [ ( 2. 43‰,167/68 638) vs ( 0. 07‰, 3 /40 939) ] . During 1995-2001 and 2002-2007, the rates of PTE of inpatients in the respiratory departments were higher than those in other departments [ 0. 004‰ ( 4/1 012 830) during 1995-2001 and 0. 05‰( 65 /1 310 114) during 2002-2007, respectively] , P lt; 0. 01. Conclusion pulmonologists play an important role in the diagnosis of PTE in the recent years.
Objective To investigate the value of different imageology methods in the diagnosis of acute pulmonary thromboembolism (PTE).Methods 22 cases diagnosed acute PTE in the last two years were retrospectively analysed，including 4 cases diagnosed by clinical signs and symptoms who did not perform further examinations due to severity of the disease (2 cases confirmed by autopsy)，18 cases diagnosed by either two methods of computed tomographic pulmonary angiography (CTPA)，ultrasound，radioisotope scanning of lung and pulmonary arteriography.The diagnostic positive rate of different methods were measured.Results 15 of the 18 subjects were performed CTPA，with a positive rate of 80.0% (12/15).Nuclide detection was performed in 14 cases，in which 5 cases were performed simple pulmonary infusion scanning，9 cases by lung ventilation/perfusion scanning，resulted in a positive rate of 92.9% (13/14).10 cases were performed nuclide phlebography on the low extremity simultaneously，deep phlebothrombosis was found in 5 subjects，and unnormal formation of collateral circulation，blocked blood circulation，stenosis of lumens，and valve disfunction et al were found in other 5 cases.16 cases were performed heart color ultrasound detection，in which 2 were found normal，one was directly found thrombus，and the other 8 cases were found indirect manifestations of acute PTE，including right ventricular enlargement，pulmonary artery hypertension，tricuspid backstreaming et al，with a diagnosing rate of 56% (9/16).Deep phlebothrombosis was found in 6 of the 10 cases who were performed color Doppler ultrasonography on the lower extremity，and one was found with valve function impaired.Conclusions CTPA possesses high positive rate in diagnosing acute PTE with promptness，convenience and reliability，thus can be taken as the front-line detection device.Radioisotope scanning of lung associated with same-time phlebography on the low extremity also has fairly high positive rate to diagnosing acute PTE and make it easy.
ObjectiveTo observe the impact of obstructive sleep apnea-hyponea syndrome (OSAHS) on the severity of pulmonary thromboembolism (PTE) and its treatment strategies. MethodsPTE patients hospitalized in our department between January 2006 and December 2012 were screened for this study, including 16 patients with OSAHS and 20 patients without OSAHS, and the difference in clinical characteristics such as arterial blood gas, apnea-hypopnea index, lowest pulse oxygen saturation (LSpO2) and treatment methods were analyzed and compared between the two groups. ResultsAs compared to PTE patients without OSAHS, the age of patients was lower[(53.4±12.1), (64.5±9.8) years; P=0.005], while body mass index[(29.3±2.2), (26.1±3.3) kg/m2, P=0.002] and smoking index (150±24, 101±18; P<0.001) were higher in PTE patients with OSAHS. Additionally, significantly lower LSpO2[(71.7±8.3), (79.4±7.1) mm Hg (1 mm Hg=0.133 kPa); P=0.005] and more lung segments (8±3, 5±2; P=0.001) were involved in PTE patients with OSAHS. In this cohort, all patients received anticoagulation and/or thrombolysis treatment, but the rate of continuous positive airway pressure (CPAP) ventilation application was significantly higher in PTE patients with OSAHS. ConclusionPTE patients with OSAHS have relatively lower age but serious condition, and both anticoagulation and CPAP should be used in the clinical treatment.
Cerebral hemorrhage is a common clinical critical disease, and venous thromboembolism is one of its common complications. How to diagnose and treat venous thromboembolism early is still the main problem in the management of patients with cerebral hemorrhage. This article reviews the concept, pathogenesis, risk factors, evaluation tools, prevention and treatment of venous thromboembolism in patients with cerebral hemorrhage. Suggestions are put forward on the development of evaluation tools and improvement of prevention and treatment, in order to provide reference for clinical management and related research of patients with cerebral hemorrhage complicated with venous thromboembolism.
ObjectiveTo comprehensively evaluate the incidence of venous thromboembolism (VTE) after colorectal surgery.MethodsWe searched PubMed/Medline, Web of science, and Embase databases by computer, collected studies by using the combination of corresponding English keywords. Then, we screened literatures according to inclusion and exclusion criteria, and evaluated the quality of literatures by using Downs and Black tools. Finally, we used Stata 15.1 and R Project 3.4.1 for meta-analysis.ResultsA total of 15 studies (n=721 730) were included in the meta-analysis. The combined incidence of VTE after colorectal surgery was 2.26% [95% CI was (1.93%, 2.61%), P<0.000 1], and the incidence of VTE after adjusting for publication bias was 1.82% [95% CI was (1.53%, 2.13%), P<0.000 1]. Meta regression analysis revealed that patients’ age (P<0.000 1), smoking (P=0.000 4), open surgery (P=0.020 0), preoperative albumin level (P=0.023 6), and malignant tumor (P=0.036 4) were correlated with the incidence of VTE after colorectal surgery, which may be potential factors for heterogeneity.ConclusionsThe incidence of VTE after colorectal surgery is not insignificant. It is necessary for clinicians to be vigilant about the occurrence of VTE after colorectal surgery and provide appropriate preventive interventions in combination with patients’ own risk factors, disease-related factors, and surgical factors.
ObjectiveTo evaluate the venous thromboembolism (VTE) risk and anticoagulant therapy in patients with coronavirus disease 2019 (COVID-19).MethodsThe patients with COVID-19 in Optics Valley Hospital of Wuhan Tongji Hospital from February 9, 2020 to March 29, 2020 were collected and analyzed. Padua scores were performed within 24 hours after admission. The relationship between Padua score, disease severity and 28 day prognosis was analyzed.ResultsCOVID-19 was diagnosed in 102 cases. The age, fibrinogen and mortality of the severe group were significantly higher than those of the common group. The Padua score of the severe group was higher than that of the common group, but there was no statistical difference. The platelet count in the critical group was significantly lower than that in the severe group, while the prothrombin time (PT), activated partial thromboplastin time (APTT), and D dimer were significantly higher than that in the severe group, and the Padua score, anticoagulation ratio, and mortality were significantly higher than those in the severe group. According to Padua score 4, it was divided into VTE high risk group (≥ 4 points) and VTE low risk group (<4 points). The mortality, APTT, D dimer and fibrinogen of high risk group were significantly higher than those of low risk group. In the high-risk group of VTE, the anticoagulation rate was significantly higher than that in the low-risk group of VTE, but it was still only 41.7%. The mortality of patients with anticoagulation was lower than that of patients without anticoagulation.ConclusionsSevere and critical novel coronavirus pneumonia patients have obvious coagulation dysfunction and high risk of VTE. Anticoagulant therapy may be associated with low mortality in patients with high risk of VTE, but the proportion of drug-induced anticoagulant intervention still needs to be improved.
Objective To observe the effectiveness of prevention and management of venous thromboembolism (VTE) in the day surgery wards, analyze the influencing factors of VTE occurrence in postoperative patients, in order to reduce the occurrence of VTE adverse events, improve the utilization of medical resources, and enhance the quality of day care. Methods The patient data of the Daytime Diagnosis and Treatment Center of Deyang People’s Hospital between January 2020 and December 2023 were retrospectively selected. According to the implementation time of VTE prevention and control in the day surgery wards, patients between 2022 and 2023 were selected as the observation group, and patients between 2020 and 2021 were selected as the control group. The incidence and the influencing factors of postoperative of VTE were compared between the two groups. Results A total of 2 300 patients were included, with 1 150 cases in each group. The comparison of in-hospital [12 cases (1.0%) vs. 3 cases (0.3%)] and post discharge [7 cases (0.6%) vs. 1 case (0.1%)] VTE incidence rates between the control group and the observation group showed statistically significant differences (P＜0.05). Among the 9 specialties in the Daytime Diagnosis and Treatment Center, the incidence of VTE in thoracic surgery (1.58%), vascular surgery (1.51%), and hepatobiliary surgery (1.29%) ranked among the top 3. The results of multiple logistic regression analysis showed that fourth grade surgery, lower limb surgery, and large intraoperative bleeding (>100 mL) were the influencing factors for postoperative VTE (P<0.05). Conclusions There are many reasons for VTE occurrence, and it is necessary to prevent and treat VTE in the day surgery ward. More attention should be paid to the patient’s surgical grading, intraoperative bleeding volume, and surgical site.
The incidence of venous thromboembolism (VTE) is relatively high in the elderly population, and the disability, mortality, and medical expenses caused by VTE are also high. However, in a large number of randomized controlled and non-randomized controlled studies related to VTE, sufficient attention has not been paid to the elderly population with multiple underlying diseases. Therefore, the vast majority of research results recommended by VTE guidelines come from younger patients and healthy elderly people, at the same time, most relevant VTE prevention and treatment guidelines or consensus are formulated for hospitalized patients, and for non-hospital elderly populations such as home and elderly care institutions that truly need attention and risk of VTE, their recommended opinions are uncertain. In this context, the Peripheral Vascular Disease Management Branch of the Chinese Geriatrics Society has developed a consensus among Chinese experts on the prevention and treatment of VET in the elderly, based on evidence-based evidence such as domestic and foreign guidelines and relevant research.
