title: The results of high-frequency duplex surveillance after iliac arterial stenting in a single center.
abstract: Frequent duplex surveillance after iliac arterial stenting is time-consuming and costly, so solid benefits of this approach must be available. Frequent duplex surveillance was performed at our center, this was reviewed retrospectively.A total of 117 stents were assessed. Duplex was done for 84 (71.8%) of 117 patients at 1 year and 25 (21.4%) of 117 at 5 years, mean follow-up 27.6 months. Totally, 456 scans were performed; 386 (84.6%) scans were normal, 43 (9.4%) showed an abnormality for which intervention was not necessary, 27 (5.9%) showed abnormalities which needed interventions. The maximum attendance of patients was 62%. In all, 18 patients had interventions unrelated to scheduled follow-up; 15 (83.3%) of 18 had no prior abnormalities on duplex, 3 (16.6%) of 18 had prior abnormalities which were not acted upon after clinical assessment. Our findings demonstrate a high nonattendance rate with frequent emergency presentations due to acute complications. We cannot, therefore, recommend frequent duplex surveillance program both in terms of results or resource allocation.
