<jats:title>Abstract</jats:title><jats:p>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. A depopulated bovine ureteric xenograft was implanted from the left subclavian artery to innominate vein. It became massively aneurysmal, requiring emergency embolization. Biopsy of the graft stained positive for α‐gal. We believe this is the first reported case of massive aneurysmal dilatation of a depopulated bovine ureteric xenograft.</jats:p>
