In patients requiring hemodialysis, arteriovenous fistulae may be created using autogenous vessels or prosthetic grafts. Complications of such operations include thrombosis, infection, venous hypertension, pseudoaneurysm, congestive heart failure, true venous aneurysms, and arterial "steal" syndrome. Of these the last two are the least common. On reviewing the English literature (Medline search: 1969-1991) we found only 8 reported cases of true venous aneurysms secondary to creation of an arteriovenous fistulae for dialysis. Hemodynamic assessment has shown that arterial "steal" is frequently present distal to an arteriovenous fistula. However, these patients rarely have ischemic symptoms. Over the last 7 years 236 patients had arteriovenous fistulae created for hemodialysis at our institution. Three of these patients (1.2%) developed true venous aneurysms. One of these 3 patients (0.4%) also had severe hand claudication due to arterial "steal". All of these patients were treated successfully without any complications. The etiology and various therapeutic options for these rare complications are discussed.
