Question: Limbs AV Fistula Declot & Stenting Failure; TPA and Repeat Stent for Extravasation
AV left forearm graft fistulogram showed extensive thrombus in main draining vein up to the level of the distal third of the humerus. Crossing sheaths placed. Angiojet catheter used to treat arterial and venous anastamosis. It worked for arterial but not venous. Angioplasty of arterial anastomosis, with arterial flow re-established. Stent was placed across venous anastamosis to improve outflow. Patient continued to clot despite administration of 10,000 units of heparin during the procedure. Multiple passes again made with the angiojet. Flow was not re-established.
