Objective  To discuss the clinical effect and value of stent placement combined with mechanical aspiration thrombectomy for acute iliofemoral venous thrombosis with iliac vein occlusion.
Methods  From October 2004 to December 2011, interventional treatment were performed in 273 patients with acute iliofemoral venous thrombosis and iliac vein occlusion, including left side of 235 cases and right side of 38 cases. Antegrade femoral vein under local anesthesia, an 8-14F catheter was inserted into iliofemoral vein with the guidance of guide wire to aspirate thrombus directly, 53 patients used 18-24F large lumen sheath to aspirate thrombus. As for the femoralpopliteal vein thrombus, a “cross sheath” was inserted to affected iliac vein with the help of guide wire capture technique, a guide wire was introd-uced to popliteal vein, then a Fogarty balloon catheter was inserted and extracted thrombus to iliac vein, mechanical aspiration thrombectomy was performed again. After iliofemoral vein thrombus were removed completely, percutaneous transluminal angioplasty (PTA) and stenting were performed for stenosis or occlusion displayed by venography.
Results  Thrombus removal were completely cleared (degreeⅢ) in 219 cases (80.22%), partly cleared (degreeⅡ) in 49 cases (17.95%), and minimal cleared (degreeⅠ) in 5 cases (1.83%). The effect of stent placement:were cured in 235 cases (86.08%), excellent in 29 cases (10.62%), mild in 2 cases (2.57%), and invalid in 7 cases (0.73%). Total effective rate was 99.27% (271/273), the average days in hospital was 7.5 days. Tumescence and pain of affected limb disappeared or relieved after interventional therapy for 1-2 days. The followe up effect:3-6 months, 7-12 months, 13-24 months, and 25-36 months after treatment of iliac vein patency were 94.87%,93.73%,87.08%,and 84.13% respectively.
Conclusion  Mechanical aspiration thrombectomy combined with stent placement for acute lower extremity deep venous thrombosis and iliac vein obstruction is an effective and safe treatment for its notable therapeutic effect and the short hospitalization time.
