Vascular access steal syndrome

Vascular Access Steal Syndrome

Vascular access steal syndrome (pronunciation: /ˈvæskjʊlər ˈæk.ses stiːl sɪnˈdroʊm/), also known as dialysis-associated steal syndrome (DASS), is a medical condition that can occur in patients undergoing hemodialysis.

Etymology

The term "steal" in the syndrome's name refers to the diversion of blood flow away from the distal extremity, which can lead to ischemia and related symptoms. The term "vascular access" refers to the site where blood is removed and returned during hemodialysis.

Symptoms

Symptoms of vascular access steal syndrome may include pain, numbness, weakness, or coolness in the hand or arm used for hemodialysis access. In severe cases, it can lead to tissue death (necrosis) and may require amputation.

Causes

Vascular access steal syndrome is caused by the creation of an arteriovenous fistula (AVF) or arteriovenous graft (AVG) for hemodialysis, which can alter normal blood flow patterns and lead to the syndrome.

Treatment

Treatment options for vascular access steal syndrome include surgical correction of the AVF or AVG, use of a banding procedure, or revascularization.
