Hemodialysis access thrombosis is the leading cause of hospitalization in the dialysis population. Thrombosis of polytetrafluoroethylene (PTFE) grafts can be treated either with surgical thrombectomy or percutaneous thrombolysis. Percutaneous aspiration thrombectomy (AT) is a new technique of rapidly recannalizing occluded PTFE grafts as an outpatient which utilizes standard 8 Fr catheters and vacuum aspiration without the need for surgery or the cost and risk of thrombolysis. Nineteen P with thrombosed PTFE grafts underwent AT with adjunctive balloon angioplasty (PTA). AT success was defined as successful declotting without the need for surgical declotting or thrombolysis. Angiographic success was defined as l30% stenosis after PTA with brisk graft flow. Clinical success was defined as immediate resumption of dialysis without need for hospitalization for anticoagulation. Acute results in 19 patients: N(%) AT success 19 (100) Adjunctive PTA 19 (100) Adjunctive stenting 2 (11) Angiographic success 17 (90) Clinical success 17 (90) Procedure time l30 minutes 12 (71) Complications 0 (0) All 17 clinically successful patients were dialyzed immediately after the procedure without difficulty. No patient required hospitalization. The 2 patients who were clinical and angiographic failures after PTA required placement of a new dialysis access. Conclusion Percutaneous aspiration thrombectomy appears to be a simple yet effective alternative to the conventional treatment of thrombosed PTFE dialysis grafts. |
