ABSTRACT: Iliac artery calcification is a common phenomenon complicating renal transplantation, particularly in those with diabetes. The potential for vascular clamp injury can threaten the renal allograft, ipsilateral lower extremity, or both.
Utilization of internal balloon occlusion can allow for placement of a “Chimney Patch” graft, fashioned from a deceased donor artery, to the calcified vessel, eliminating the risk of clamp injury and minimizing warm ischemic time.
We present a series of 6 patients transplanted with internal balloon occlusion with successful renal and pancreatic allograft function and no ipsilateral vascular complications.
Internal balloon occlusion is a safe and effective adjunct for renal or pancreas transplant to prevent clamp injury with no adverse effect on allograft function.
