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.

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.

Application of negative pressure closed drainage in the treatment of venous ulcer of lower limbs

Venous ulcer of lower extremities is a serious manifestation of venous insufficiency of lower extremities in the later stage,which is characterized by inflammatory exudation at the initial stage,followed by skin rupture,and finally forms the whole layer of skin atrophy and necrosis,which does not heal for a long time.How to promote ulcer healing is the most important problem in the treatment of venous ulcers of lower extremities.Vacuum sealing drainage(VSD)is constantly used in clinic and plays a unique advantage in wound healing.This paper mainly reviews the present situation of venous ulcer of lower extremities and summary,principle,application progress,attentions and prospect of VSD at home and abroad.

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.

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.

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.

Application of Color Doppler Ultrasonic Examination in Deep Vein Valvular Incompetence in Lower Limbs

By use of color Doppler Flow Imaging (CDFI), the morphologic and hemodynamic parameters such as the diameters of femoral and popliteal veins,blood flow velocity and the reflux 0f valve area were examined in lower extremity deep valvular incompetence (DVI) and normal control gr0ups. The purpose was to evaluate the value of CDFI in the diagnosis of DVI. The results demonstrated that the parameters between the two groups had a very significant difference (P<0. 001), indicating that the CDFI is non-invasive, cost-effective and safe and it might serve as a practical tool in the diagnosis of lower extremity deep va1vular incompetence.

Analysis thrombolysis with anticoagulation treatment for early stage of deep vein thrombosis in the lower extremities

Objective: To explore the effect of thrombolysis with anticoagulation treatment for early stage of deep vein thrombosis of lower extremity. Methods: The clinical data of 106 patients at the early stage of deep vein thrombosis (DVT) in the lower extremities treated by thrombolysis with anticoagulation and dispersion drugs were analyzed retrospectively. Results: The thrombolytic effect was significant. After treatment, the deep veins were recanalized without regurgitation in 75.3% of the patients. The total effective rate was 100%. Only three patients had hemorrhagic complication, but none of the patients died. Conclusion: Thrombolysis with anticoagulation treatment is an effective and safe method for DVT at the early stage.

Lower Extremity Ulcers in Patients with Systemic Sclerosis

Introduction: Cutaneous manifestations of systemic sclerosis (SSc) include skin ulceration;4% - 12% of patients with SSc develop lower extremity ulcers of various etiologies. Limited data, significant morbidity, and substantial cost of wound care led us to undertake this study to describe and identify risk factors. Methods: After Institutional Review Board approval, we identified 30 patients with SSc and lower extremity ulcers over a 10-year period at a single center with an SSc clinic, which were included in a descriptive analysis. Results: Median age of onset of lower extremity ulcers was 59.5 years (range 20 - 84). Ninety percent of patients were female, 60% were Caucasian, 63% had limited SSc, 13% diffuse SSc and 23% an overlap syndrome. Immunomodulators or steroids were prescribed in 53%;hypercoagulable state identified in 16%. Ulcers were attributed to venous stasis (27%), SSc (20%), trauma (20%), arterial disease (17%), and multifactorial/unknown (17%). In patients with ulcers attributed to SSc, age at onset was lower (45.5 vs 59.5 years). Biopsies generally did not contribute to management. Multidisciplinary treatment was routine;20% required amputation, 10% endovascular intervention, 20% frequent surgical debridement, 10% hyperbaric oxygen, 26% local treatment and antibiotics and 13% received immunosuppression for wound treatment. Conclusion: Lower extremity ulcers are a serious clinical problem in patients with SSc. The clinical exam, venous dopplers, ankle-brachial indices and assessment of vascular risk factors helped define causality. In younger patients, ulcers were more frequently attributed to SSc and these patients were more likely to be on immunosuppressants/DMARDS, possibly indicating severe phenotype of SSc.

目的 分析创伤性膝关节骨性关节炎(TKOA)患者行关节镜微骨折术效果及术后下肢静脉血栓形成危险因素。方法 回顾性选取2020年3月至2023年3月佳木斯市中心医院收治的80例TKOA患者进行研究,按照治疗方法不同将其分为对照组(n=30)与观察组(n=50)。对照组行常规膝关节手术,观察组行关节镜微骨折术,分析两组的临床治疗效果和下肢静脉血栓发生率。另根据术后是否发生下肢静脉血栓将观察组患者分为有血栓组和无血栓组,分析两组患者的一般特征,并建立多因素Logistic模型分析分析影响关节镜微骨折术后下肢静脉血栓形成的独立危险因素。结果 观察组的总有效率为96.00%,高于对照组(80.00%),差异有统计学意义(P<0.05)。观察组下肢静脉血栓发生率为24.00%,低于对照组(46.67%),差异有统计学意义(P<0.05)。与无血栓组比较,有血栓组年龄≥60岁、高血脂症、止血带应用时间>90 min、术后卧床时间≥3 d、手术时间≥1 h率和Caprini评分较高(P<0.05)。单因素分析结果显示,年龄、高血脂症、止血带应用时间、术后卧床时间、手术时间、Caprini评分均是TKOA患者关节镜微骨折术后下肢静脉血栓形成的影响因素(P<0.05)。多因素Logistic分析结果显示,年龄≥60岁、高血脂症、止血带应用时间>90 min、术后卧床时间≥3 d、手术时间≥1 h、Caprini评分均是TKOA患者关节镜微骨折术后下肢静脉血栓形成的独立危险因素(P<0.05)。结论 关节镜微骨折术在TKOA治疗中效果较为显著,但受年龄过大、术后卧床时间和手术时间过长等因素影响极易引发下肢静脉血栓,只有加强对该类影响因素的预防干预,才能有效降低患儿的下肢静脉血栓形成风险。
