ObjectiveTo summarize the current research progress on the relationship between thyroid cancer and venous thromboembolism.MethodsRetrieved the literatures about risk factors associated with thyroid cancer and venous thromboembolism both at home and abroad in recent years and reviewed the literatures.ResultsThe incidence of venous thromboembolism in patients with thyroid cancer was not high, and there were few factors related to risk factors, it might be related to the age of patient and the time of diagnosis of thyroid cancer. In addition, various types of therapeutic drugs for thyroid cancer might lead to the occurrence of venous thromboembolism.ConclusionsThe study of thyroid cancer and venous thromboembolism related factors and prethrombotic state occurrence are necessary to reduce the incidence of venous thromboembolism in thyroid cancer and improve prognosis.
Objective To investigate the compliance status of intermittent pneumatic compression device (IPCD) in patients after lumbar surgery, and to analyze the reasons and influencing factors affecting compliance. Methods The continuous enrollment method was used to select patients who underwent posterior decompression for lumbar degenerative diseases in the orthopedic department of Peking Union Medical College Hospital between December 2022 and June 2023. The general information of patients and their compliance with IPCD were collected, and the reasons that affected compliance were analyzed. ResultsA total of 46 patients were included. The overall proportion of patients with good compliance was relatively low, and their compliance was poor. On the first and second day after surgery, the daytime compliance was relatively good (the proportion range of excellent compliance was 39%-52%); the compliance at night was significantly lower than that during the daytime (the proportion range of excellent compliance was 21%-26%); after 3 days of surgery, the patients’ compliance significantly decreased. A total of 460 time periods were observed and 195 reasons for not using IPCD were collected. The main reasons were physical discomfort caused by the device, inconvenience during bedside activities, and little significance to the patient. The compliance of female patients was better than that of males (P<0.05). Patients with education level of primary school and below had the highest compliance, while patients with high school and above had the lowest compliance (P<0.05). There was no statistically significant difference in compliance among patients of different age groups (P>0.05). Conclusions The overall compliance of patients with IPCD after lumbar surgery is poor, which is an urgent clinical problem, and the adaptability and cognitive level of patients to the device are the main factors affecting compliance. In clinical nursing work, men and patients with higher education level should be strengthened.
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.
Objective To explore the correlation between risk factors in respiratory department patients and the occurrence of venous thromboembolism (VTE), and to evaluate the optimization of the Padua score for predicting VTE occurrence in hospitalized respiratory patients based on these correlations. The effectiveness of the modified assessment model for VTE prediction was also validated. Methods A retrospective study was conducted, involving 51 VTE patients who were hospitalized in the Respiratory Department of Huaian First People’s Hospital from March 2019 to July 2023. These patients were compared with 1,600 non-VTE patients who were discharged during the same period. Clinical data, including medical history and laboratory test results, were retrospectively collected from both groups. The correlation between clinical data and VTE occurrence was analyzed, and highly relevant risk factors were incorporated into the Padua score. The modified Padua risk assessment model was applied to all patients and validated in a validation group. The scores from both the original and modified risk assessment models were compared to evaluate the effectiveness of the modified Padua score. Results Rank sum tests showed significant differences in basic information, such as age, BMI, and length of hospital stay, as well as laboratory tests including mean corpuscular volume, procalcitonin, albumin, alanine aminotransferase, aspartate aminotransferase, urea, and D-dimer (P<0.05). Univariate and multivariate logistic regression analyses revealed that newly identified high-risk factors for VTE included hypoalbuminemia (OR=2.972), blood transfusion (OR=47.035), and mechanical ventilation (OR=6.782) (P<0.05). Receiver operating characteristic curve analysis showed that the sensitivity and specificity of the modified Padua score were higher than those of the original version. The area under the curve (AUC) difference was 0.058, with a Z-test value of 2.442, showing statistical significance (P<0.05). Conclusions The modified Padua score demonstrated superior predictive ability for VTE in hospitalized respiratory patients compared to the original Padua score.
Objective To analyze the clinical features of rickettsial infection complicated with pulmonary embolism and to improve clinicians’ knowledge of rickettsial infection complicated by thromboembolism events. Methods We retrospectively analyzed the clinical data of a patient with pulmonary thromboembolism complicated by Rickettsial felis infection and conducted a review of the relevant literature. The search terms "Rickettsia/Scrub typhus, thrombosis" or "Rickettsia/ Scrub typhus, embolism" were used to search the Wanfang ,VIP ,Chinese National Knowledge Infrastructure and PubMed databases from January 1985 to May 2023, respectively. Results The 81-year-old male patient was admitted to the hospital on June 1, 2021 due to "dizziness, sore throat for 11 days, fever for 7 days, and shortness of breath for 3 days". Physical examination revealed a eschar-like rash behind the left ear, venous thrombosis in both lower limbs was detected by color ultrasound, computed tomographic pulmonary angiography indicated multiple pulmonary embolism in both lungs, and positive rickettsiae on peripheral blood next-generation sequencing, confirming the diagnosis of Rickettsial felis infection complicated by venous thromboembolism (VTE) in both lower limbs and pulmonary embolism. Twenty manuscripts, including 20 cases, were retrieved from databases. Among them, Rickettsial felis infection combined with thromboembolism event was not found. With the addition of our case, a total of 21 cases were analyzed in detail. Six of the 21 cases were complicated with VTE, 10 with pulmonary embolism, 5 with intracranial venous thrombosis, 6 with thrombosis at other sites (jugular venous thrombosis, mesenteric thrombosis, aortic thrombosis, etc), and 8 of which had concurrently involved systemic thrombosis. Of the 4 deaths, 2 cases had mesenteric embolism, 1 case had cerebral infarction, and 1 case had systemic multiple thrombus. Conclusions Rickettsial infection symptoms and signs are often atypical, can be complicated with lower limb VTE or pulmonary embolism. Early identification, diagnosis and treatment are very important, especially for patients with dyspnea, chest pain and other related symptoms.
Inpatients after COVID-19 infection, especially those admitted to intensive care unit (ICU), may encounter a series of coagulation dysfunction, which may lead to thrombosis, such as pulmonary embolism (PE), deep vein thrombosis (DVT) or arterial thrombosis (AT). Although there are many literatures on the incidence rate, prevention and treatment of venous thromboembolism (VTE) in hospitalized patients with COVID-19 infection, there are few data on the symptomatic and subclinical incidence rate of VTE after COVID-19 infection discharge. Therefore, there are no specific recommendations or guidelines for the prevention of VTE after discharge from hospital due to COVID-19 infection, and the current guidelines are controversial. In this study, we reviewed and summarized the existing literature on the incidence rate, prevention, diagnosis and treatment of venous thromboembolism in patients with COVID-19 infection, in order to provide guidance for VTE prevention in patients with COVID-19 infection after discharge.
ObjectiveTo investigate association between the nutrition-related indicators and the recurrence of venous thromboembolism (VTE). MethodsThe clinical data from the patients with VTE receiving 3 or 6 months of anticoagulation therapy at the West China Hospital of Sichuan University, from January 2020 to October 2022, were retrospective analyzed. The multivariate logistic regression analysis was used to assess the association between the nutrition-related indicators such as albumin to fibrinogen ratio (AFR) and prognostic nutrition index (PNI) and VTE recurrence. The test level was set as α=0.05. ResultsA total of 141 patients with VTE were enrolled, of whom 12 (8.5%) experienced recurrence within 2 years. The multivariate logistic regression analysis identified several risk factors for recurrence, including diabetes [β=–3.368, OR (95%CI)=0.034 (0.001, 0.920), P=0.044], pulmonary embolism [β=–0.454, OR (95%CI)=0.635 (0.423, 0.954), P=0.029], and decreased AFR [β=–0.454, OR (95%CI)=0.635 (0.423, 0.954), P=0.029], but it was not found that the PNI was associated with VTE recurrence [β=–0.153, OR (95%CI)=0.858 (0.722, 1.020), P=0.083]. ConclusionThe findings of this study indicate that close monitoring for recurrent VTE is warranted in patients with diabetes mellitus, pulmonary embolism, and decreased AFR receiving anticoagulation therapy.
Objective
To investigate the risk factors and prevention methods of the venous thromboembolism (VTE) after hepatectomy.
Methods
The literatures about VTE after hepatectomy in recent years at home and abroad were reviewed and summarized.
Results
The risk factors for postoperative VTE include tumor, male, old age, massive hepatectomy, hypercoagulability, etc. The incidence of VTE in patients with massive hepatectomy is significantly higher, which is closely related to the hypercoagulability caused by postoperative liver dysfunction. Effective prophylaxis include mechanical methods and anticoagulant drugs, the latter of which can markedly reduce the incidence of VTE. For patients who develop postoperative liver insufficiency, including those with cirrhosis and high risk of bleeding, anticoagulant VTE prophylaxis dosing decisions should be made with caution. In addition, it is rationale for extended thromboprophylaxis in high risk patients.
Conclusions
VTE is a common complication after hepatectomy, resulting in prolonged postoperative hospital stay and increased postoperative mortality. Therefore, it is important to determine the risk of VTE after surgery to improve the prognosis of patients after hepatectomy.
ObjectiveTo evaluate efficacy and safety of early anticoagulation therapy with low molecular weight heparin (LMWH) in prevention of venous thromboembolism (VTE) after pancreatoduodenectomy (PD).MethodsThe patients who received PD in our hospital from January 2017 to December 2018 were collected retrospectively, then were divided into the anticoagulant group and the non-anticoagulant group. The operation time, intraoperative blood loss, tumor property, coagulation function indexes such as prothrombin time (PT), PT activity (PTA), fibrinogen (FIB), activated partial thromboplastin time (APTT), thrombin time (TT), and D-dimer (DD), platelet (PLT), VTE, bleeding related complications etc. were compared between the two groups.ResultsA total of 103 patients underwent PD were included in this study, including 52 patients in the anticoagulant group and 51 patients in the non-anticoagulant group. There were no significant differences in the baseline data such as the gender, age, and preoperative coagulation function indexes, etc. between the two groups (P>0.05). The incidence of VTE in the anticoagulant group was lower than that in the non-anticoagulant group (13.5% versus 47.1%, P<0.001). There was no significant difference in the incidence of bleeding between the anticoagulant group and the non-anticoagulant group (9.6% versus 7.8%, P>0.05). There were no statistically significant differences in the coagulation indexes between the two groups before operation and day 1 after operation (P>0.05). On day 8 after operation, the FIB and DD values of the anticoagulant group were significantly lower than those of the non-anticoagulant group (P values were 0.040 and 0.002, respectively). A comparison of different phases in the same group on coagulation indexes between day 8 and day 1 after surgery showed that there were statistically significant differences (P<0.05), the changes of all indexes were within the normal range.ConclusionThe results of this study indicate that LMWH administered at 24 h after PD could decrease incidence of VTE and don’t increase risk of bleeding.
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.
