When fistulas and grafts become clogged or narrowed, an Interventional Radiologist uses multiple techniques to correct the problem:


•  Catheter directed thrombolysis- which involves injecting a medicine that dissolves blood clots that build up in fistulas and grafts.

•  Catheter directed mechanical thrombectomy-where the clot is physically removed or macerated.

•  Angioplasty and vascular stenting which use mechanical devices such as balloons and stents to keep fistulas and grafts patent.
