Efficacy of percutaneous mechanical thrombus removal in acute lower extremity deep venous thrombosis

BACKGROUND Acute lower extremity deep venous thrombosis(LEDVT)is a common vascular emergency with significant morbidity risks,including post-thrombotic syndrome(PTS)and pulmonary embolism.Traditional treatments like catheter-directed thrombolysis(CDT)often result in variable success rates and complications.AIM To investigate the therapeutic efficacy of percutaneous mechanical thrombus removal in acute LEDVT.METHODS A retrospective analysis was performed to examine 58 hospitalised patients with acute LEDVT between August 2019 and August 2022.The patients were categorised into the percutaneous mechanical thrombectomy(PMT)group(n=24)and CDT group(n=32).The follow-up,safety and treatment outcomes were compared between the two groups.The main observational indexes were venous patency score,thrombus removal effect,complications,hospitalisation duration and PTS.RESULTS The venous patency score was 9.04±1.40 in the PMT group and 8.81±1.60 in the CDT group,and the thrombus clearance rate was 100%in both groups.The complication rate was 8.33%in the PMT group and 34.84%in the CDT group,and the difference was statistically significant(P<0.05).The average hospitalisation duration was 6.54±2.48 days in the PMT group and 8.14±3.56 days in the CDT group.The incidence of PTS was lower in the PMT group than in the CDT group;however,the difference was not statistically significant(P<0.05).CONCLUSION Compared with CDT,treatment of LEDVT via PMT was associated with a better thrombus clearance rate,clinical therapeutic effect and PTS prevention function,but the difference was not statistically significant.Moreover,PMT was associated with a reduced urokinase dosage,shortened hospitalisation duration and reduced incidence of complications,such as infections and small haemorrhages.These results indicate that PMT has substantial beneficial effects in the treatment of LEDVT.

Clinical Value of Predictive Nursing Intervention on Deep Venous Thrombosis of Lower Extremities after Cesarean Section

[Objectives]To explore the clinical nursing value of predictive nursing intervention in patients with deep venous thrombosis of lower extremities after cesarean section.[Methods]From December 2022 to April 2023,105 pregnant and lying-in women who were hospitalized in the Gynecology Department of Pingquan Hospital and underwent cesarean section and met the inclusion criteria were included as the study objects.According to the medical records,they were divided into observation group(n=52 cases)and control group(n=53 cases).The clinical experimental subjects were divided into two groups.One group was the control group with routine nursing,and the other group was the observation group with predictive nursing intervention.The number of cases of deep venous thrombosis of lower extremities in the two groups was recorded to evaluate the clinical value.[Results]The incidence of deep venous thrombosis of lower extremities in the two groups after cesarean section was compared,and it was suggested that the incidence of the observation group was lower than that of the control group(P<0.05).[Conclusions]Special predictive nursing intervention can greatly reduce the incidence of deep venous thrombosis of lower extremities after cesarean section,improve nursing satisfaction,and improve clinical efficacy,which is worthy of recommendation.

Prevention and management of postoperative deep vein thrombosis in lower extremities of patients with gastrointestinal tumor

BACKGROUND Deep vein thrombosis(DVT)is a significant postoperative concern,particularly in patients undergoing surgery for gastrointestinal(GI)cancers.These patients often present multiple risk factors,including advanced age and elevated body mass index(BMI),which can increase the likelihood of thromboembolic events.Effec-tive prophylaxis is crucial in this high-risk population to minimize complications such as DVT and pulmonary embolism(PE).This study investigates a compre-hensive DVT prevention protocol,combining mechanical and pharmacological strategies alongside early mobilization,to evaluate its effectiveness and safety in reducing postoperative thrombosis rates among GI cancer surgery patients.AIM To evaluate the effectiveness and safety of postoperative DVT prevention strate-gies in patients with GI cancer.METHODS A prospective cohort study was conducted involving 100 patients who underwent surgery for GI tumors between January and December 2022.All patients received a standardized DVT prevention protocol,which included risk assessment,mecha-nical prophylaxis,pharmacological prophylaxis,and early mobilization.The primary endpoint was the incidence of DVT within 30 days postoperatively.Se-condary outcomes included the occurrence of PE,bleeding complications,and adherence to the protocol.RESULTS The overall incidence of DVT was 7%(7/100 patients).One patient(1%)deve-loped PE.The adherence rate to the prevention protocol was 92%.Bleeding complications were observed in 3%of patients.Significant risk factors for DVT development included advanced age[odds ratio(OR):1.05;95%confidence interval(95%CI):1.01-1.09],higher BMI(OR:1.11;95%CI:1.03-1.19),and longer operative time(OR:1.007;95%CI:1.001-1.013).CONCLUSION Implementing a comprehensive DVT prevention and management protocol for patients undergoing GI tumor surgery resulted in a lower incidence.Strict adherence and individualized risk assessment are crucial for optimizing outcomes.

Diagnostic Value of the Padua Score Combined with Thrombotic Biomarker Tissue Plasminogen Activator Inhibitor-1 (tPAI-1) Detection for the Risk of Deep Vein Thrombosis in Patients with Pulmonary Heart Disease

This study explores the diagnostic value of combining the Padua score with the thrombotic biomarker tissue plasminogen activator inhibitor-1(tPAI-1)for assessing the risk of deep vein thrombosis(DVT)in patients with pulmonary heart disease.These patients often exhibit symptoms similar to venous thrombosis,such as dyspnea and bilateral lower limb swelling,complicating differential diagnosis.The Padua Prediction Score assesses the risk of venous thromboembolism(VTE)in hospitalized patients,while tPAI-1,a key fibrinolytic system inhibitor,indicates a hypercoagulable state.Clinical data from hospitalized patients with cor pulmonale were retrospectively analyzed.ROC curves compared the diagnostic value of the Padua score,tPAI-1 levels,and their combined model for predicting DVT risk.Results showed that tPAI-1 levels were significantly higher in DVT patients compared to non-DVT patients.The Padua score demonstrated a sensitivity of 82.61%and a specificity of 55.26%at a cutoff value of 3.The combined model had a significantly higher AUC than the Padua score alone,indicating better discriminatory ability in diagnosing DVT risk.The combination of the Padua score and tPAI-1 detection significantly improves the accuracy of diagnosing DVT risk in patients with pulmonary heart disease,reducing missed and incorrect diagnoses.This study provides a comprehensive assessment tool for clinicians,enhancing the diagnosis and treatment of patients with cor pulmonale complicated by DVT.Future research should validate these findings in larger samples and explore additional thrombotic biomarkers to optimize the predictive model.

This is an update on the first edition of the expert consensus. This document discusses the indications and contraindications of interventional treatment methods for deep venous thrombosis such as anticoagulation, catheter-directed thrombolysis, percutaneous mechanical thrombectomy, percutaneous transluminal angioplasty and stent implantation. The operational procedures, considerations, preoperative management, and prevention of complications were also updated, supplemented, and revised. Emphasis is placed on the interventional treatment of acute and subacute deep venous thrombosis to effectively reduce the incidence of post-thrombosis syndrome.

The effect of nursing intervention based on Autar scale results to reduce deep venous thrombosis incidence in orthopaedic surgery patients

Purpose:To reduce the incidence of deep venous thrombosis(DVT)with nursing intervention based on the Autar DVT risk assessment scale among orthopaedic surgery patients.Methods:We recruited 216 orthopaedic surgery patients at our hospital between September 2013 and March 2014.The patients were assigned to intervention and historical control groups based on the time of admission.Using the Autar DVT risk assessment scale,we assessed the DVT risk levels in both groups;the intervention group received the corresponding prophylactic measures while the control group received routine nursing.Results:The DVT incidence rate and the D-dimer level on postoperative day 3 in the intervention group were lower(1.82%;623±225 mg/L,respectively)than that of the control group(9.43%;825±201 mg/L,respectively);both differences were statistically significant(p<0.05).Conclusions:The Autar scale is beneficial when used in orthopaedic surgery patients;corresponding nursing intervention based on Autar scale assessment can prevent DVT effectively.

Clinical Study on Effect of Osteoking (恒古骨伤愈合剂) in Preventing Postoperational Deep Venous Thrombosis in Patients with Intertrochanteric Fracture

Objective： To evaluate the effect of Osteoking （恒古骨伤愈合剂） in preventing postoperational deep venous thrombosis （DVT） in patients with intertrochanteric fracture （ITF）. Methods： With prospective and randomized controlled clinical design adopted, 62 patients with ITF after operation were assigned into 2 groups, the tested group and the control group, Osteoking （25 ml every other day） and Sanchidansheng tablets （三七丹参片, 3 tablets thrice a day） were given orally to them respectively for 10 days. Difference of round length of thighs and shanks between two sides were measured on the 10th day and Doppler ultrasonic examination on the fractured leg was carried out. Results： The occurrence rate of DVT in the tested goup was 9.4%, which was lower than that in the control group （30.0%, P〈0.05）. All the difference of round lengths, either that of the thigh or the shank, was less in the tested group than that in the control group, showing statistical significance （P〈0.05）. Conclusion： Osteoking has a satisfactory effect in preventing postoperational DVT in patients with ITF.

Two-point compression ultrasonography: Enough to rule out lower extremity deep venous thrombosis?

BACKGROUND: Deep venous thrombosis(DVT) is a major cause of morbidity and is a common presenting complaint to the emergency department(ED). Point-of-care two-point compression ultrasonography has evolved as a quick and effective way of diagnosing DVT. The purpose of this study is to validate the prevalence and distribution of venous thrombi isolated to proximal lower extremity veins, other than common femoral and popliteal veins in patients with DVT.METHODS: This is a single-center retrospective study that looked at patients presenting to the ED of a tertiary care hospital between January 2014 and August 2018. The clinical presentation and laboratory and imaging results were obtained using the hospital's electronic medical record.RESULTS: A total of 2,507 patients underwent a lower extremity duplex ultrasound during the study period. Among them, 379(15%) were included in the study. The percentages of isolated thrombi to the femoral vein and deep femoral vein were 7.92% and 0.53%, respectively. When the patients were stratified into the two groups of isolated DVT and two-point compression DVT, there were no statistically significant differences in the laboratory results between both groups. However, immobilized patients and patients with recent surgeries were more likely to have an isolated DVT.CONCLUSIONS: Thrombi isolated to proximal lower extremity veins other than the common femoral and popliteal veins make up 8.45% of DVTs. Given this significant number of missed DVTs, the authors recommend the addition of the femoral and deep femoral veins to the two-point compression exam.

Perioperative Management of Case of Gynecological Malignancy with Bilateral Deep Venous Thrombosis of Lower Limbs Along with Pulmonary Embolism

We describe the anaesthetic management of 45 year female patient with pre-existing deep venous thrombosis (DVT) and pulmonary embolism (PE) who was subsequently scheduled for an laparotomy. Before planning the surgical procedures, adequate anticoagulation must be achieved to prevent further complications of DVT, thromboembolism, and pulmonary embolism in particular. The risk of stopping the anticoagulation prior to surgery must be considered and adequately discussed with the patient and surgeons. The anaesthetic plan must be selected keeping in mind the coagulation status and the need of anticoagulation in the postoperative period.

Deep Venous Thrombosis: Commonly Affected Veins in the Lower Limbs

Aim and Objectives: This study aimed to record the commonly affected veins in the lower limbs, to compare the affected sides and gender and to correlate the Doppler findings and stages of deep venous thrombosis (DVT). Materials and Methods: A descriptive retrospective study of 46 already diagnosed cases of lower limb DVT. Results: Out of 46 cases of DVT, 71.74% were females. The majority of patients (93.47%) were affected in unilateral lower limb with significant predominance (65.22%) to affect the left lower limb (p Conclusion: Lower limb deep venous thrombosis affects left lower limb more than right and females more than males. Superficial femoral vein (SFV) and common femoral vein (CFV) are the most common affected veins. Lower limb DVT predominantly present in acute stage with venous distension and absent blood flow.

Combined MR Imaging for Pulmonary Embolism and Deep Venous Thrombosis by Contrast-enhanced MR Volume Interpolated Body Examination

MR pulmonary angiography(MRPA)combined with indirect MR venography(MRV)was attempted by using 3D contrast-enhanced MR volume interpolated body examination(VIBE)sequence.Agreement rate for deep venous thrombosis(DVT)detection between MRV and duplex sonography(DUS)was evaluated;the potential of this method for venous thromoembolism(VTE)was also investigated.Thirty-four patients with DUS-identified DVT were enrolled in this study.MRI was performed after a single administration of Gadopentetate dimeglumine.Fatsuppressed 3D VIBE was applied for visualizing pulmonary arteries,abdominal veins,pelvic and leg veins,ranging from lung apex to ankle level.Two radiologists observed the MR images in consensus,recorded the location and number of emboli.MRV images were assessed based on per-vein segment.The agreement rate between MRV and DUS for venous segment-to-segment comparison was analyzed by Wilcoxon rank sum test.All the patients were diagnosed as having DV 1 by MRV.MRV detected 55 more venous segments with thrombi than DUS based on per-vein segment analysis.Twenty-three patients with pulmonary embolism(PE)were detected by MRPA.Twenty-one patients underwent both pulmonary CT angiography and MRPA,and consistency for PE detection was 100%.Total examination time of the combined MR protocol was 7 min for each patient.The contrast-enhanced VIBE sequence proves to be a feasible and reliable method for VTE diagnosis in one-stop MR scanning procedure,and contrast-enhanced VIBE performs better to depict DVT than DUS on per-vein segment basis.

Comparison of four clinical scores for the predicting lower limb deep venous thrombosis in Chinese patients

Objective：To evaluate Wells, Kahn, St.Andr 6 and Constans scores for the prediction of deep venous thrombosis in Chinese patients. Methods：One hundred and seventy-two patients, prospectively, blinded referred for evaluation with four clinical-score systems for suspected deep venous thrombosis, were examined by ultrasonography. Sensitivity, specificity, positive predictive value, negative predictive value and receiver operation curves were calculated for four clinical scores. The difference between areas of the ROC curve for each of the scores was compared with others and reference line. Results：Forty-six of 172 patients had deep venous thrombosis proven by sonography. The sensitivity, specificity, positive predictive value and negative predictive value for Wells score was 91.3%, 57.1%, 43.8% and 94.7%, respectively, for Kahn score; 65.2%, 71.4%, 45.5% and 84.9%, respectively, for St.Andr 6 score; 63%, 38.9%, 27.4% and 74.2% respectively, for Constans score; 95.7%, 34.9%, 34.9% and 95.7% respectively. Area under ROV curve of Constans score was 0.814, which was similar to that of Wells score, then followed by Kahn score and that of St.Andr 6 score was no difference with the reference line. Conclusion：Based on the results of our study, the sensitivity, negative prediction value and area under ROC curve are larger for Constans score and Wells score in Chinese hospitalized patients than that of Kahn score or St.Andr 6 score. Considering the aim of the clinical assessment, Constans score and Wells score are more efficient for Chinese hospitalized patients.

Carbohydrate Antigens as Potential Biomarkers for the Malignancy in Patients with Idiopathic Deep Venous Thrombosis:A Retrospective Cohort Study

A variety of biomarkers have been identified in recent prospective and retrospective re- ports as being potentially predictive of venous thromboembolis （VTE）, particularly idiopathic deep venous thrombosis （IDVT）. This study identified a serum tumor biomarker for early screening of IDVT. A total of 128 IDVT patients （54 females and 74 males; average age： 50.9＋17.4 years） were included. Carcinoembryonic antigen （CEA）, ferritin, β2-microglobulin, cancer antigen （CA） 125, CA 15-3, CA 19-9, squamous cell carcinoma antigen （SCC）, alpha-fetoprotein （AFP）, prostate specific antigen （PSA）, free PSA （f-PSA）, and beta-human chorionic gonadotropin （13-HCG） in patients with IDVT were detected. Malignancies were histo- or cytopathologically confirmed. Of the 128 IDVT patients, 16 （12.5%） were found to have malignarteies. Serum CEA, CA 125, CA 15-3, and CA 19-9 were found to be helpful for detecting malignancies in IDVT patients. Our study revealed a positive association between these markers and tumors in IDVT patients. On the other hand, SCC and AFP were not sensitive enough to be markers for detecting tumors in patients with IDVT. No significant differences were found in positive rates of ferritin and 132-microglobulin between turnor and non-ttmaor groups, and no significant difference exists in serum levels of ferritin and 132-microglobulin between the two groups. Carbohydrate antigens, CA 15-3 in particular, may be useful for differential diagnosis and prediction of malignancies in patients with IDVT.

Acute deep venous thrombosis induced by May-Thurner syndrome after spondylolisthesis surgery:A case report and review of literature

BACKGROUND Deep venous thrombosis(DVT)is a serious complication of lumbar spine surgery.Current guidelines recommend pharmacomechanical prophylaxis for patients at high risk of DVT after spine surgery.May-Thurner syndrome(MTS),a venous anatomical variation that may require invasive intervention,is an often overlooked cause of DVT.To date,no case reports of symptomatic MTS caused by isthmic spondylolisthesis or subsequent acute DVT after posterior lumbar surgery have been published.CASE SUMMARY We here present a case of a patient who developed acute DVT 4 h after spondylolisthesis surgery,and MTS was only considered after surgery,during a review of a gynecological enhanced computed tomography image taken before the procedure.CONCLUSION In conclusion,clinicians should consider MTS in the presence of a dangerous triad:spondylolisthesis,elevated D-dimer levels,and sonographically indicated unilateral deep vein dilation.Consultation with a vascular surgeon is also essential to MTS management.

Deep Venous Thrombosis in Breast Cancer Patients Using Tamoxifen, a Hypothesis

Breast cancer is the most frequently diagnosed cancer in women and systematic therapy is an essential component of disease. Hormonal therapy, cytotoxic chemotherapy and the more recently introduced biological therapies are routinely employed in the vast majority of patients. Several pharmaceuticals that affect the estrogenic pathways have been studied as chemopreventive agents. Tamoxifen is an anti-estrogenic drug used in the treatment of estrogen receptor positive breast cancer patients. One of the important side-effects of tamoxifen is thromboembolic events like deep venous thrombosis. Tamoxifen also causes an increase in mean platelet volume. We hypothesize that thromboembolic effect of tamoxifen is via increase of mean platelet volume.

Case-control analysis of venous thromboembolism risk in nonalcoholic steatohepatitis diagnosed by transient elastography

BACKGROUND Nonalcoholic fatty liver disease(NAFLD)is the most common cause of chronic liver disease worldwide.Studies have shown a strong association between nonalcoholic steatohepatitis(NASH)cirrhosis and portal vein thrombosis.Specifically,there is paucity of data on the association of NASH and venous thromboembolism(VTE),with one such study predicting a 2.5-fold increased risk for VTE compared to other liver diseases in hospitalized patients.The mechanism is believed to be a hepatocellular injury,which causes a chronic inflammatory state leading to the unregulated activation of procoagulant factors.There has been no prior analysis of the degree of steatosis and fibrosis(measured using transient elastography,commonly known as FibroScan)in NASH and its association with VTE.AIM To examine the association between the degree of hepatic steatosis and fibrosis,quantified by transient elastography,and the incidence of VTE in patients with NASH.METHODS In our case-control study,we included patients with a documented diagnosis of NASH.We excluded patients with inherited thrombophilia,hemoglobinopathy,malignancy,alcohol use disorder,autoimmune hepatitis,and primary biliary cirrhosis.The collected data included age,demographics,tobacco use,recreational drug use,medical history,and vibration controlled transient elastography scores.VTE-specific data included the location,type of anticoagulant,need for hospital stay,and history of VTE recurrence.Steatosis was categorized as S0-S1(mild)and S2-S3(moderate to severe)based on the controlled attenuation parameter score.Fibrosis was classified based on the kilopascal score and graded as F0-F1(Metavir stage),F2,F3,and F4(cirrhosis).χ^(2) and Mann-Whitney U tests were used for the qualitative and quantitative variable analyses,respectively.Furthermore,we performed a logistic regression using VTE as the dependent variable.RESULTS A total of 415 patients were analyzed,and 386 met the inclusion criteria.51 and 335 patients were included in the VTE and non-VTE groups,respectively.Patients with VTE had a mean age of 60.63 years compared to 55.22 years in the non-VTE group(P<0.014).Patients with VTE had a higher body mass index(31.14 kg/m²vs 29.30 kg/m²)and a higher prevalence of diabetes mellitus(29.4%vs 13.1%).The history of NASH was significantly higher in the VTE group(45.1%vs 30.4%,P<0.037).Furthermore,moderate-to-severe steatosis was significantly higher in the VTE group(66.7%vs 47.2%,P<0.009).Similarly,the F2-F4 fibrosis grade had a prevalence of 58.8%in the VTE group compared to 38.5%in the non-VTE group(P<0.006).On logistic regression,using VTE as a dependent variable,diabetes mellitus had an odds ratio(OR)=1.702(P<0.015),and F2-F4 fibrosis grade had an OR=1.5(P<0.033).CONCLUSION Our analysis shows that NASH is an independent risk factor for VTE,especially deep vein thrombosis.There was a statistically significant association between the incidence of VTE,moderate-to-severe steatosis,and fibrosis.All hospitalized patients should be considered for medical thromboprophylaxis,particularly those with NASH.
