title: Stenotic lesions in vascular access: treatment with transluminal angioplasty using high-pressure balloons.
abstract: In our institute, one hundred sixty-four balloon dilatations of stenotic lesions in vascular access have been performed since November 1991. All of these procedures were done with high-pressure balloon catheters. In addition to seventy-four cases treated with only percutaneous transluminal angioplasty, there were thirty-four cases which were treated by thrombectomy and/or surgical revision with subsequent intraoperative balloon angioplasty. These angioplastic procedures were initially successful in 142 (87%) of 164 stenoses. The patency rate after 3 months was 68%; after 6 months, 42%; and after 1 year, 25%. There were no serious adverse reactions in our series. This procedure can be safely done with minimal traumatization and, although long-term patency rates are low, repeated dilatations can be performed with ease, when restenosis occurs, to keep a fistula functioning for a long time in appropriate patients.
