A successful struggle to prolong arteriovenous fistula patency: a case report.

An adequate vascular access (VA) significantly determines the morbidity and mortality of chronic renal failure (CRF) patients on maintenance hemodialysis (HD). VA patency depends on the early identification of complications and its management by the nephrologists and vascular surgeon. Venous stenosis accounts for the majority of thromboses, but its early detection followed by either percutaneous angioplasty (PTA) and/or surgical correction will improve fistula patency. We present the clinical case report of a 90-year-old patient with recurrent central venous stenosis after PTA that was corrected with bypass surgery. Two years after surgery the original fistula is still used showing no signs of access dysfunction.
