Abdominal collateral veins as an unconventional access site for hemodialysis after primary access failure.

Introduction: Vascular access dysfunction and the depletion of access pathways are complications associated with morbidity and mortality in dialysis patients. As described in the literature, catheter insertion through small collateral veins or recanalized cervical and thoracic veins is an attractive option.

Case Description: This article reports a case in which a collateral vein in the abdominal region was used as an access for hemodialysis.
