Methods Fifteen acute PE patients admitted from January 2003 to June 2009 were treated with percutaneous catheter drawing of thrombus, thrombectomy, and thrombolysis. Local infusion and immediate intra-venous injection of urokinase with 100 000 000 U in total were used for thrombolysis. Afterwards, the low molecular weight heparin was given for seven to ten days, and an oral intake of warfarin lasts for three to six months. Observe the clinical symptoms, improvement of physical signs, occurrence of complications, change of mean pulmonary arterial pressure (mPAP) and arterial partial pressure of oxygen (PO2), as well as the patency condition of pulmonary artery. Results Twelve of fifteer patients gained complete patency of pulmonary artery, and the other three patients gained partial patency, with an obvious effectiveness rate of 89% and an effectiveness rate of 100%. mPAP decreased from (41. 07±6. 97) mm Hg to (21. 00±5. 66) mm Hg, and PO2 elevated from (46. 26±9. 30) mm Hg to (79. 49±8. 04) mm Hg, showing a significant difference (Plt;0. 05) before and after the therapy. The immediate clinical symptoms exhibited a significant improvement. The pulmonary artery pressure of 11 patients dropped rapidly. During three to six months’ follow up, the therapeutic effects persisted and no recurrence was found. Conclusion The interventional treatment of acute PE demonstrates remarkable effectiveness, safety and feasibility, which plays an important role in the rescue of critical patients, improvement of clinical symptoms, and maintenance of hemodynamic stability.
Objective To explore the therapeutic effect of catheter-directed thrombolysis combined with vena cava filter on deep venous thrombosis (DVT) of lower extremity.Methods The clinical data of 65 patients with DVT of lower extremities from January 2008 to August 2009 were analyzed retrospectively, whose course of diseases were not more than 7 d and clinical type included central type and mixed type. Thirty-two cases were treated with catheter-directed thrombolysis combined with vena cava filter, while administrating treatment of anticoagulation and activating blood circulation to dissipate blood stasis, which were named as study group. Thirty-three cases were treated traditionally with thrombolysis, anticoagulation, and activating blood circulation to dissipate blood stasis, which were named as control group. The course of therapy was continued 10-14 d, then the efficacy in two groups patients was evaluated. Results It was (7.35±1.42) cm that circumference difference before treatment between affected extremties and unaffected extremties in study group, which of 3, 7, and 14 d after treatment was (4.21±1.12) cm， (2.87±0.98) cm, and (1.22±1.02) cm, respectively. Circumference difference between before and after treatment had significant difference in study group (Plt;0.01). It was (6.97±1.27) cm that circumference difference before treatment between affected extremties and unaffected extremties in control group, which of 3, 7, and 14 d after treatment was (5.72±1.31) cm, (4.58±0.88) cm, and (3.18±1.24) cm, respectively. Circumference difference between before treatment and 3, 7, and 14 d after treatment had significant difference in control group (Plt;0.05 or Plt;0.01). Circumference difference before treatment in two groups had no significant difference (Pgt;0.05). Circumference difference after treatment at different time points in two groups was significantly different, respectively (Plt;0.01). Circumference difference after treatment at different time points in study group was significantly less than that in control group, respectively (Plt;0.01). After 14 d, complete recanalization rate （71.88%, 23/32） and cure rate (71.88%, 23/32) of iliofemoral vein in study group were significant higher than that (36.36%, 12/33) in control group (Plt;0.01). No pulmonary embolism occurred. Conclusion In terms of ideal therapy targets of DVT of lower extremity, the catheterdirected thrombolysis combined with vena cava filter is obviously superior to traditional thrombolysis treatment.

ObjectiveTo investigate the significance of catheter thrombolysis combined with one-stage iliac vein percutaneous transluminal angioplasty (or stent implantation) in the treatment of acute left lower extremity deep venous thrombosis secondary to Cockett syndrome.MethodsForty-one cases of Cockett syndrome complicated with acute left lower extremity deep vein thrombosis were retrospectively analyzed and summarized in our hospital from January 2016 to June 2019. Catheter directed thrombolysis was performed under the protection of filter, and percutaneous transluminal angioplasty or stent implantation was performed in the first stage of the iliac vein stenosis or occlusion after thrombolysis. Compared the circumference of upper and lower legs of 15 cm above and below patella of the healthy and affected limbs, before and after treatment, and analyzed the venous patency rate.ResultsThe average time of using thrombolytic catheter were (7±3) days, and the average dosage of urokinase was (358.32±69.38) ×104 U. A total of thirty-five Bard stents were implanted (35 cases), four cases underwent percutaneous transluminal angioplasty, and two cases gave up treatment. Before and after treatment, the circumference difference of the higher leg, the circumference difference of the lower leg, and the venous patency were significantly different before and after thrombolysis (P<0.01). The venous patency rate was 58%–75% in this group, and the average venous patency rate was (61±10)%. There was no severe bleeding complication occurred. Thirty-five patients were followed up for 3–26 months, the preservation rate of the valve was 82.86% (29/35), and the first patency rate of iliac vein was 100% (39/39). During the follow-up period, thrombosis recurred in one case of untreated iliac vein, and acute thrombosis in the right side of one case was caused by long iliac vein stent entering the inferior vena cava. No pulmonary embolism was found.ConclusionOn the basis of catheter thrombolysis, one stage removal of iliac vein obstruction in the treatment of acute left lower extremity deep venous thrombosis can relieve the clinical symptoms, reduce the recurrence rate of thrombosis, and reduce the occurrence of deep vein thrombosis syndrome after catheter thrombolysis.
