To present experience with percutaneous balloon-assisted aspiration thrombectomy (BAT) for the treatment of patients with clotted hemodialysis access grafts.
BAT was performed with use of 7-F intravascular sheaths and a Fogarty balloon catheter. It was tested with an in vitro flow-circuit model. Twenty consecutive BAT procedures were performed in 15 patients with clotted grafts. The balloon catheter was advanced through the sheath to the arterial anastomosis. The balloon was inflated and withdrawn while suction was applied from the sideport to recover thrombus. The procedure was repeated for the venous limb. BAT was used alone in 12 procedures and in combination with urokinase in eight procedures.
Almost complete thrombectomy was achieved in all tubes (in vitro), with very low venous and arterial embolic fractions. Technical success (restored graft thrill and almost complete thrombectomy) was achieved in 18 cases (90%). Clinical success (patency after 1 week of dialysis) was achieved in 17 cases (85%).
Percutaneous BAT is feasible in recently clotted dialysis grafts.
介绍经皮球囊辅助抽吸血栓切除术（BAT）治疗血液透析通路移植物血栓形成患者的经验。
使用7F血管鞘和Fogarty球囊导管进行BAT。在体外血流循环模型上进行测试。对15例移植物血栓形成的患者连续进行了20次BAT手术。将球囊导管通过鞘推进至动脉吻合口。充气并抽出球囊，同时从侧孔施加吸力以回收血栓。对静脉端重复该操作。12例手术单独使用BAT，8例手术联合使用尿激酶。
所有管道（体外）几乎均实现了完全血栓清除，静脉和动脉栓塞分数极低。18例（90%）获得技术成功（恢复移植物震颤且几乎完全血栓清除）。17例（85%）获得临床成功（透析1周后通畅）。
经皮BAT对近期血栓形成的透析移植物可行。
