Streptokinase and transluminal angioplasty in the treatment of acutely thrombosed hemodialysis access fistulas

RS Rodkin, JJ Bookstein, DJ Heeney and GB Davis

Streptokinase was selectively infused into nine thrombosed hemodialysis access fistulas in eight patients. Lysis occurred in all but one case. Of the eight infusions producing lysis, seven resulted in some clinical benefit. Three grafts functioned adequately for 2 to 6 months after streptokinase infusion alone. A fourth patient had good function for over 11 months after streptokinase treatment and transluminal angioplasty. In a fifth patient, graft function was partially restored, but a persistent arterial defect led to elective graft replacement. Moderate fibrinolysis in the sixth case was of no clinical benefit; rethrombosis developed promptly after SK was discontinued because of bleeding from a recent puncture site. In cases 7 and 8, fibrinolysis restored arterial inflow to the graft, but surgery was needed to revise partially obstructed venous outflow. It is concluded that selective streptokinase infusion, with or without transluminal angioplasty and operation, is often effective in the treatment of acutely thrombosed vascular access fistulas.
