Figure 3From: The use of tissue plasminogen activator as continuous infusion into an arteriovenous hemodialysis access in the hemodialysis unit: a case series Fistulogram images of radio-cephalic fistula. a: Fistulogram unable to demonstrate anastomosis with a clotted radio-cephalic fistula and no flow of contrast material past the point of the stenosis (arrow indicating stenosis). b: Post pharmacomechanical thrombolysis in radiology suite demonstrating poor flow through the same fistula with heavy clot burden. c: Fistulogram one week later with repeat angioplasty of existing stenosis, after hemodialysis tPA infusion. No clot was demonstrated. Residual stenosis indicated by arrows.Back to article page
