ABSTRACT
Objective:To investigate the feasibility, indication selection and treatment of Catheter- directed thrombolytic therapy with endovascular angioplasty for TASC- D type aorto- iliac artery occlusive diseases.Methods:From Jan 2014 to Jun 2017, the clinical data of 27 patients (33 limbs) with TASC- D type aorto- iliac artery occlusive diseases were analyzed retrospectively.Results:After catheter embolization , 31 limbs were successfully treated with endovascular angioplasty, the success rate was 93.9% (31/33). ankle brachial index (ABI) of successful limbs improved from (0.47±0.09) preoperatively to (0.80±0.11) postoperatively ( P<0.01). The patency rates of 6、12、24 months were 90.32%, 80.65%, 77.42%. One case (3.85%)suffered hematoma.There were no other major complications such as iliac artery rupture, arteriovenous fistula, deep vein thrombosis or pseudoaneurysm. Conclusions:Catheter-directed thrombolytic therapy can effectively reduce artery lumen thrombosis volume. Catheter- directed thrombolytic therapy with endovascular angioplasty for TASC- D type aorto- iliac artery occlusive diseases is a safe and effective treatment.
