RESUMEN
Objective To evaluate the mid-term and long-term result of mechanical aspiration thrombectomy or combined with balloon thrombectomy,venoplasty and catheter-directed thrombolysis therapy for lower extremity deep venous thrombosis.Methods Clinical data of 1 068 admitted patients were analysed retrospectively from January 2000 to June 2010.Among these patients,271 cases were treated by thrombectomy only,537 cases received thrombectomy with arterial catheter-directed thrombolysis,260 cases were treated by thrombectomy with dorsalis pedis vein thrombolysis,492 patients with stenosis or obstruction of iliac vein underwent venoplasty treatment.Results After 36 month follow-up edema,pigmentation and chronic ulcers were 10.26％,7.28％,1.55％ respectively.The patency without reflux,patency with reflux,residual thrombus,occlusion rate of the iliofemoral vein were 84.25％,8.95％,4.3％,2.5％ respectively; The patency,residual thrombus and occlusion rate of popliteal vein were 93.32％,5.49％,1.19％.Iliac vein stent patency rate was 92.28％.Conclusions Endovascular treatment for lower extremity deep venous thrombosis was a reasonable therapy with a satisfactory mid-term and long-term result,protecting venous valve function and reducing the morbidity of post-thrombotic syndrome.
