[Transluminal percutaneous angioplasty of stenosis of arteriovenous fistulas; 24-month follow-up]. / Angioplastica percutanea transluminare delle stenosi di fistole artero-venose. Follow-up di 24 mesi.

Stenosis is a common cause of the functional loss of vascular shunts used in chronic hemodialysis and percutaneous transluminal angioplasty represents the elective method to correct these anomalies. A total of 42 percutaneous transluminal angioplasties were performed, with a prospective study and follow-up lasting an average of 18 months, in 32 patients with insufficient blood flow of arteriovenous fistula. In over 90% of cases the procedure restored adequate hemodynamic conditions that remained unchanged during follow-up. The authors therefore conclude that percutaneous transluminal angioplasty is an efficacious, easily performed and low-cost method that does not present major complications.
