Massive aneurysmal dilatation of a depopulated ureteric hemodialysis xenograft.

Use of depopulated bovine ureteric xenografts for hemodialysis vascular access has recently been described. Cellular components have been removed, giving a connective tissue matrix which can be neocellularized, retaining native biomechanics. A 24-year-old male with end-stage renal disease from focal segmental glomerulosclerosis presented with particularly difficult vascular access.
