Dialysis-associated steal syndrome as a rare complication of arteriovenous fistula angioplasty

The angioplasty of arteriovenous fistulas (AVF) has become indispensable in preserving haemodialysis access. Though well-known complications, such as pseudoaneurysm formation and rupture, can occur, the incidence of severe dialysis-associated steal syndrome (DASS) following AVF angioplasty is low. We describe a patient with limited dialysis options who developed significant DASS following angioplasty of his AVF. After excluding flow-limiting causes of DASS, the patient underwent a successful Revision Using Distal Inflow procedure, redirecting blood flow to his distal arm. Subsequently, all ischaemic symptoms resolved. While effective surgical options are available for the management of DASS, preventive measures such as proper angioplasty balloon sizing remain key.
