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.

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.

Discussion on Prevention and Treatment of Lower Extremity Deep Venous Thrombosis in Orthopedic Perioperative Period from Spleen and Stomach Meridians

Deep venous thrombosis of lower extremity is one of the common complications in orthopedic perioperative period.It is caused by many factors,such as peripheral vein dilation,slow blood flow;long-term immobilization,bed rest and so on.On the one hand,it affects the early postoperative functional exercise and functional recovery,on the other hand,it increases the length of hospital stay and economic burden,increases the pain of patients and even endangers their lives.Effective treatment of traditional Chinese medicine combined with western medicine can play a better role in the prevention and treatment of lower extremity deep venous thrombosis.This study expounds the concept of spleen and stomach meridians in the prevention and treatment of lower extremity deep venous thrombosis,and puts forward some opinions on the dialectical treatment and daily conditioning of lower extremity deep venous thrombosis,hoping to provide ideas for the clinical prevention and treatment of lower extremity deep venous thrombosis in traditional Chinese medicine.

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.

Manual aspiration thrombectomy for acute and subacute inferior vena cava thrombosis and lower extremity deep venous thrombosis

Deep vein thrombosis(DVT), which can lead to pulmonary embolism(PE), is a major contributor to the global disease burden and is the third most common cardiovascular pathology after coronary artery disease and stroke. Venous thromboembolic disease, which encompasses the disease entities of DVT and PE, affects up to 10 million cases every year and represents a serious and potentially life-threatening condition. Standard anticoagulation therapy alone is ineffective at promoting deep venous system thrombus removal. Many patients develop postthrombotic syndrome(PTS) despite being on adequate anticoagulation therapy. Aggressive therapy for rapid thrombus removal is important to prevent the development of PTS. Besides impeding the onset of PTS, rapid clearance of the thrombus is also required in the treatment of phlegmasia cerulea dolens, an uncommon but life-threatening complication of acute DVT that can lead to arterial insufficiency, compartment syndrome, venous gangrene, and limb amputation. Manual aspiration thrombectomy(MAT) can provide rapid and effective therapy that could be compared to the open surgical thrombectomy approach with minimal risk of morbidity, mortality, or recurrence after surgery. Though many devices have been developed to date for pharmacomechanical thrombolysis, the cost of the treatment using these devices is very expensive. MAT is simple to perform, easy to learn, inexpensive, and rapid. This review will outline and dissect several studies and case reports, sourced from the Pub Med database, on the subject of the use of MAT in treating inferior vena cava thrombosis and lower extremity DVT, including in patients with compression of the iliac vein and phlegmasia cerulea dolens.

Clinical Application of Percutaneous Transluminal Angioplasty and Stent Implantation in Acute Lower Extremity Deep Venous Thrombosis

Purpose: To analyze the application of percutaneous transluminal angioplasty and stenting in acute deep venous thrombosis of lower extremities. Methods: 70 patients were divided into two groups according to the presence or absence of percutaneous transluminal angioplasty and stenting. Results: The mean circumferential diameter difference between the affected limbs and the healthy limbs and the knees at 15 cm was statistically significant. The cure rate and effective rate of the research group were higher than those of the control group (P<0.05). Conclusion: Percutaneous transluminal angioplasty and stenting are of high value in acute lower extremity deep venous thrombosis.

Establishment of a nomogram model for predicting therapy complications in patients with polycythemia and deep venous thrombosis

BACKGROUND Patients with deep venous thrombosis(DVT)residing at high altitudes can only rely on anticoagulation therapy,missing the optimal window for surgery or thrombolysis.Concurrently,under these conditions,patient outcomes can be easily complicated by high-altitude polycythemia(HAPC),which increases the difficulty of treatment and the risk of recurrent thrombosis.To prevent reaching this point,effective screening and targeted interventions are crucial.Thus,this study analyzes and provides a reference for the clinical prediction of thrombosis recurrence in patients with lower-extremity DVT combined with HAPC.AIM To apply the nomogram model in the evaluation of complications in patients with HAPC and DVT who underwent anticoagulation therapy.METHODS A total of 123 patients with HAPC complicated by lower-extremity DVT were followed up for 6-12 months and divided into recurrence and non-recurrence groups according to whether they experienced recurrence of lower-extremity DVT.Clinical data and laboratory indices were compared between the groups to determine the influencing factors of thrombosis recurrence in patients with lowerextremity DVT and HAPC.This study aimed to establish and verify the value of a nomogram model for predicting the risk of thrombus recurrence.RESULTS Logistic regression analysis showed that age,immobilization during follow-up,medication compliance,compliance with wearing elastic stockings,and peripheral blood D-dimer and fibrin degradation product levels were indepen-dent risk factors for thrombosis recurrence in patients with HAPC complicated by DVT.A Hosmer-Lemeshow goodness-of-fit test demonstrated that the nomogram model established based on the results of multivariate logistic regression analysis was effective in predicting the risk of thrombosis recurrence in patients with lowerextremity DVT complicated by HAPC(χ^(2)=0.873;P>0.05).The consistency index of the model was 0.802(95%CI:0.799-0.997),indicating its good accuracy and discrimination.CONCLUSION The column chart model for the personalized prediction of thrombotic recurrence risk has good application value in predicting thrombotic recurrence in patients with lower-limb DVT combined with HAPC after discharge.

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.

Choosing ankle tourniquets in foot and ankle surgery: Beyond postoperative pain considerations

This editorial critically explores the use of ankle vs thigh tourniquets in foot and ankle surgery based on a recent study that found no significant difference in postoperative pain between the two placement techniques.Despite these findings,we argue for the preferential use of ankle tourniquets,highlighting their potential benefits in reducing venous blood stasis and minimizing soft tissue injury.This approach underscores the importance of considering long-term patient outcomes and vascular health beyond immediate postoperative pain.By integrating study findings with broader clinical considerations,we hereby advocate for a nuanced approach to tourniquet use that prioritizes patient safety and long-term recovery in conjunction with immediate postoperative pain.
