Comparison of Two Clinical Scales to Assess the Post-thrombotic Syndrome: Secondary Analysis of a Multicenter Randomized Trial of Pharmacomechanical Catheter-Directed Thrombolysis for Deep Venous Thrombosis

Objective To identify predictors of post-thrombotic syndrome in patients with iliofemoral deep venous thrombosis who underwent catheter-directed thrombolysis. Methods Fifty-two consecutive patients who underwent catheter-directed thrombolysis were included in this retrospective study. In addition to catheter-directed thrombolysis, aspiration thrombectomy or stent placement was performed if needed. At six months, duplex ultrasound was performed to assess iliofemoral patency and deep venous reflux. Post-thrombotic syndrome was assessed using the clinical, etiologic, anatomic, and pathophysiologic classification (post-thrombotic syndrome present ≥3 on a scale from 0 to 6). Univariate analysis and multivariate logistic regression were used to identify predictors of post-thrombotic syndrome. Results Median follow-up was 52 months and post-thrombotic syndrome developed in nine patients (17.3%). In univariate analysis, stent placement (odds ratio 0.16, p = 0.022) was negatively associated with post-thrombotic syndrome, whereas iliofemoral venous obstruction with reflux at six months (OR 6.08, p = 0.037) was positively associated with post-thrombotic syndrome. Multivariate analysis indicated that stent placement was associated with reduced risk of post-thrombotic syndrome (OR 0.17, p = 0.043), and iliofemoral obstruction with reflux was associated with increased risk (OR 6.67, p = 0.046). Conclusion Stent placement and iliofemoral venous obstruction with reflux, respectively, were important protective and risk factors for post-thrombotic syndrome in patients who underwent catheter-directed thrombolysis.

Background Catheter-directed thrombolysis may prevent post-thrombotic syndrome in patients with ilio-femoral deep venous thrombosis. We performed a retrospective review of prospectively collected follow-up data to evaluate the results of catheter-directed thrombolysis at our institution. Method Patients admitted for venous thrombolysis were included in the study and their files screened for information regarding results and technical aspects of treatment and patient status on follow-up. A catheter was inserted under imaging guidance into the thrombosed vein. Through the catheter tissue plasminogen activator was administered. Daily catheter-based venographies were performed to monitor progression in thrombus resolution. After thrombolysis flow-limiting stenosis was stented. Patients started wearing compression stockings and were started on oral anticoagulant therapy. Follow-up visits with ultrasound, magnetic resonance venography and clinical assessment were scheduled at six weeks and three, six, 12 and 24 months. Results A total of 48 patients underwent catheter-directed thrombolysis, including 36 female patients. Median age was 28 years. Complete lysis of the thrombus was achieved in 43 cases and partial lysis in two cases and 26 stents were placed. No deaths or life-threatening bleeding events occurred. Thirty-two of the patients who achieved full lysis and were followed up remained patent at follow-up. At 12 months seven patients had symptoms of post-thrombotic syndrome. Conclusion Catheter-directed thrombolysis represents a safe and effective alternative to systemic anticoagulative treatment of deep venous thrombosis with rapid resolution of the thrombus and few complications. Long-term patency shows good validity and this study suggests that catheter-directed thrombolysis is effective in preventing post-thrombotic syndrome.

Abstract Screening

Objectives The aim was to assess the effectiveness and safety of catheter-directed thrombolysis in children with deep venous thrombosis and to evaluate its long-term effect. Method and results EMBASE, Medline and Cochrane databases were searched to identify studies in which paediatric acute deep venous thrombosis patients received thrombolysis. Following title and abstract screening, seven cohort studies with a total of 183 patients were identified. Technical success was 82% and superior in regional rather than systemic thrombolysis (p < 0.00001). One cohort study identified significant difference in thrombus resolution at one year between thrombolytic and anticoagulant groups (p = 0.01). The complication rate was low, with incidence rates of major bleeding, pulmonary embolism and others at 2.8%, 1.8% and 8.4%, respectively. The overall post-thrombotic syndrome rate was 12.7%. The incidence of re-thrombosis ranged from 12.3% to 27%. Conclusion Thrombolysis for paediatric deep venous thrombosis is an effective and relatively safe therapeutic option, lowering the incidence of post-thrombotic syndrome and deep venous thrombosis recurrence.

Abstract. Background: Here, we update an earlier systematic review on the preventive efficacy of active compression stockings in patients with diagnosed proximal deep venous thrombosis (DVT) by including the results of recently published trials. The aims are to synthesize the results of the original studies, and to identify details to explain heterogeneous results. Methods: We searched the Cochrane Library, PubMed, Scopus, and Medline for original studies that compared the preventive efficacy of active compression stockings with placebo or no compression stockings in patients with diagnosed proximal DVT. Only randomized controlled trials (RCTs) were included. Results: Five eligible RCTs with a total of 1393 patients (sample sizes ranged from 47 to 803 patients) were included. In three RCTs, patients started to wear compression stockings, placebo stockings or no stockings within the first three weeks after the diagnosis of DVT. The results of two RCTs indicate a statistically significant reduction in post-thrombotic syndrome (PTS) of 50% or more after two or more years. The result of one RCT shows no preventive effect of compression stockings at all. Due to the heterogeneity of the study results, we refrained from pooling the results of the RCTs. In a further RCT, randomization to groups with and without compression stockings took place six months after the diagnosis of DVT, and in another RCT, only patients with the absence of PTS one year after the diagnosis of DVT were analyzed. One RCT revealed a significant reduction in symptoms, whereas another RCT failed to show any benefit of using compression stockings. Conclusions: At this time, it does not seem to be justifiable to entirely abandon the recommendations regarding compression stockings to prevent PTS in patients with DVT. There is evidence favoring compression stockings, but there is also evidence showing no benefit of compression stockings.
