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.

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.

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.
