HeRO Graft candidates are those patients with central venous stenosis (CVS) or venous outflow obstruction that are:

• Catheter-dependent or approaching catheter-dependency
• Failing fistulas or grafts
• Unable to achieve prescribed flow rates
• Unable to achieve adequacy of dialysis (KDOQI target clearance = 1.4 Kt/V)

However, as with conventional grafts, the HeRO Graft may occlude in patients with:

• A small brachial artery (e.g., less than 3mm)
• Insufficient arterial inflow or inflow stenosis
• A history of clotted accesses for unknown reasons
• A coagulability disorder or medical condition that is associated with clotting (i.e., cancer)
• Insufficient anticoagulation or non-compliance with anticoagulation medication
• Systemic low blood pressure or severe hypotension following fluid removal post dialysis

Thrombosis is the most common cause of vascular access dysfunction. Missed hemodialysis sessions significantly increase the number of thrombosis episodes in AVFs and AVGs.¹  HeRO Graft thrombosis rates are comparable to conventional grafts and are treated with similar methods.²
