The purpose of this study was to compare the efficacy and safety associated with catheter-directed thrombolysis (CDT) using either recombinant tissue plasminogen activator (rt-PA) or urokinase (UK) for subacute deep venous thrombosis (DVT). From January 2014 to December 2016, we conducted a retrospective analysis on a total of 49 patients who underwent consistent CDT with either rt-PA (rt-PA-CDT group) or UK (UK-CDT group) treatment. The thrombolytic rate of the rt-PA-CDT group was significantly higher than that of the UK-CDT group (87.5% vs 60%, respectively; χ2 = 4.751; P = .029). The rt-PA-CDT group exhibited an improved grade III thrombolytic rate (9 patients vs 3 patients; χ2 = 5.144; P = .023). The time for the rt-PA-CDT group to achieve a grade III thrombolytic rate was shorter than that of the UK-CDT group (5.01 ± 1.09 days vs 6.43 ± 1.69 days, respectively; t = −2.187; P = .044). No severe complications were seen in either group and mild complications rates were 16.7% and 20.0% (χ2 = .091; P = .763). The clinical efficacy rates at discharge were 91.7% and 76.0%, respectively (χ2 = 2.200; P = .138). In conclusion, CDT with a continuous infusion of low-dose rt-PA resulted in safe and effective thrombolysis in the great majority of patients with proximal DVT in the subacute phase. Furthermore, rt-PA was significantly better than UK in terms of the thrombolytic rate. In our study, rt-PA-CDT improved the thrombolytic rate of grade III thrombus and achieved a grade III thrombolytic rate in a shorter time than UK-CDT.

Objectives The objective of this study was to evaluate the efficacy and safety in patients with acute lower extremity deep venous thrombosis who underwent pharmacomechanical thrombectomy (PMT, AngioJet mechanical thrombus aspiration). Methods In this retrospective, 424 consecutive patients with acute lower extremity deep venous thrombosis from three institutions were enrolled in the study from January 2015 to December 2018. Of these, patients were divided into two groups, AngioJet group ( n = 186) and catheter-directed thrombolysis (CDT) group ( n = 238). Evaluation indexes including limb circumference difference, length of stay (LOS), urokinase dosage, periprocedural complications, follow-up imaging findings and villalta scores were analyzed from the medical records. Results A total of 424 patients diagnosed with acute lower extremity deep venous thrombosis were collected in this study. These patients were categorized into AngioJet group and CDT group. Significant differences were observed between the two groups with respect to the thigh circumference difference (5.32 ± 1.85 cm vs. 4.69 ± 2.15 cm; p = 0.04), calf circumference difference (2.79 ± 1.54 cm vs. 2.35 ± 1.25 cm; p = 0.01), thigh detumescence rate (72.19 ± 19.55% vs. 65.35 ± 17.26%; p = 0.00) and calf detumescence rate (62.79 ± 18.56% vs. 55.75 ± 17.27%; p = 0.00). The mean dose of urokinase in AngioJet group was 95.16 ± 45.89 million IU significantly less than that in the CDT group 293.76 ± 42.71 million IU ( p = 0.00). The overall bleeding complication rate was 9.91% (19 patients in AngioJet group and 23 patients in CDT group), which included three major (0.71%, 3/424) and 39 minor (9.2%,39/424) events. In the AngioJet group, serum creatinine (sCr) concentration and urine erythrocyte from the hemolysis caused by the mechanical process were higher than baseline data at admission ( p = 0.00, p = 0.00). The postoperative red blood cell and hemoglobin in two groups were lower than baseline data ( p = 0.00, p = 0.00). Compared with CDT, AngioJet thrombectomy has significantly lower estimated incidence of PTS in the follow-up. Conclusion AngioJet thrombectomy has stronger clearance ability for acute lower extremity deep venous thrombosis leading to significant reduction in the consumption of hospital resources, total dose of thrombolytic agents, and infusion time, thereby preventing adverse bleeding events, but patients with renal insufficiency should be careful. Ideal short-term and medium-term efficacy and safety are certain.

BackgroundWe aimed to review the efficacy and safety of recanalisation procedures for the treatment of PE.MethodsWe searched PubMed, the Cochrane Library, EMBASE, EBSCO, Web of Science and CINAHL databases from inception through 31 July 2015 and included randomised clinical trials that compared the effect of a recanalisation procedure versus each other or anticoagulant therapy in patients diagnosed with PE. We used network meta-analysis and multivariate random-effects meta-regression to estimate pooled differences between each intervention and meta-regression to assess the association between trial characteristics and the reported effects of recanalisation procedures versus anticoagulation.ResultsFor all-cause mortality, there were no significant differences in event rates between any of the recanalisation procedures and anticoagulant treatment (full-dose thrombolysis: OR 0.60; 95% CI0.36 to 1.01; low-dose thrombolysis: 0.47; 95% CI 0.14 to 1.59; and catheter-associated thrombolysis: 0.31; 95% CI 0.01 to 7.96). Full-dose thrombolysis increased the risk of major bleeding (2.00; 95% CI 1.06 to 3.78) compared with anticoagulation. Catheter-directed thrombolysis was associated with the lowest probability of dying (surface under the cumulative ranking curve (SUCRA), 0.67), followed by low-dose thrombolysis (SUCRA, 0.66) and full-dose thrombolysis (SUCRA, 0.55). Similarly, low-dose thrombolysis was associated with the lowest probability of major bleeding (SUCRA, 0.61), followed by catheter-directed thrombolysis (SUCRA, 0.54) and full-dose thrombolysis (SUCRA, 0.17). The results were similar in sensitivity analyses based on restricting only to studies in haemodynamically stable patients with PE.ConclusionsIn the treatment of PE, recanalisation procedures do not seem to offer a clear advantage compared with standard anticoagulation. Low-dose thrombolysis was associated with the lowest probability of dying and bleeding.Trial registration numberPROSPERO CRD42015024670.

SummaryThe feasibility of catheter-directed thrombolysis with recombinant staphylokinase was evaluated in six selected patients with deep vein thrombosis. The patients underwent intrathrombus infusion of recombinant staphylokinase (2 mg bolus followed by a continuous infusion of 1 mg/h). Heparin was given via the catheter as a bolus (5000 U) and as a continuous infusion (1000 U/h). Complete lyis was obtained in five patients and partial lysis in one patient. Complications consisted of minor bleeding in four subjects. Symptomatic reocclusion occurred in one. Debulking of the thrombus mass by a high speed rotating impeller (n = 1) and stenting (n = 3) were used as additional interventions. An underlying anatomical abnormality was present in two patients. Long term follow up revealed normal patency in all patients and normal valve function in four patients. Symptomatic venous insufficiency with valve dysfunction was present in the two with a second thrombotic episode.Thus catheter-directed infusion of recombinant staphylokinase in patients with deep vein thrombosis appears feasible and may be associated with a high frequency of thrombolysis. Larger studies to define the clinical benefit of this treatment appear to be warranted.
