However, few studies have longitudinally evaluated vascular remodeling after DCB treatment using ultrasound. This study aimed to evaluate vascular remodeling after DCB treatment using high-frequency ultrasound.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>\n                      In this retrospective single-center study, 50 patients with single AVF stenosis were treated with DCB and followed by ultrasound at four time points: pre-treatment, immediately post-treatment, 3\u2009months, and 6\u2009months. Patients were classified into short-term (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      \u2009=\u200924; reintervention within 6\u20139\u2009months) and long-term (\n                      <jats:italic toggle=\"yes\">n<\/jats:italic>\n                      \u2009=\u200926; patency \u2a7e18\u2009months) groups. The mean follow-up time in the long-term group was 24.5\u2009months. Nineteen patients had complete ultrasound data every 3\u2009months up to 15\u2009months. Parameters included lumen cross-sectional area (L-CSA), external cross-sectional area (E-CSA), and intima-media thickness area (IMT area).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Baseline demographics were similar between groups.
