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.展开更多

Methods:...Objective: To test the therapeutic effect of integrated traditional Chinese and western medicine on venous ulcer of lower limbs by Meta analysis method, and then to propose the best clinical treatment scheme. Methods: Domestic databases in the past 20 years (January 1999-December 2019) were searched by computer, including China Journal Full-text Database (CNKI), VIP, Wanfang and CBM. Literature was screened according to inclusion and exclusion criteria. Cochrane risk assessment tool was used to evaluate the quality of the included literature. Two-classification method was used to extract data. RevMan 5.3 software was used to make statistical analysis of the data. Results: Eleven articles were finally included, totaling 1,576 patients, 804 cases in the treatment group and 772 cases in the control group. Meta-analysis results show that there is no difference in heterogeneity and bias among the included literatures. The total effective rate (risk ratio [RR]=1.12, 95% confidence interval [CI]=1.09-1.15) of integrated traditional Chinese and western medicine in treating venous ulcer of lower limbs is higher, which is obviously better than that of western medicine alone. Conclusion: Through data analysis, it is concluded that in the study population, the treatment of integrated traditional Chinese and western medicine has a significant effect on venous ulcer of lower limbs. Make up for the deficiency of simple western medicine treatment, improve the cure rate and reduce the recurrence rate. However, there is currently a lack of relevant high-quality literature, so a large sample size, rigorous and standardized experimental design and randomized double-blind clinical study are needed to further test the conclusions.展开更多

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.展开更多

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.展开更多

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.展开更多

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.展开更多

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.展开更多
