Sonographic detection of a radiolucent object in dialysis vascular access

Abstract

Percutaneous endovascular angioplasty is a valuable tool to salvage dialysis vascular access failure, but is accident-prone if performed by unskilled operators. We report a case of vascular access failure caused by the plastic protective tube of a balloon catheter, which had been mistakenly left in the vasculature and was undetectable on radiography but was detected by ultrasonography.
