1 Efficacy of duplex ultrasound surveillance after infrainguinal vein bypass may be enhanced by identification of characteristics predictive of graft stenosis development  Chelsey N. Tinder, MD, Joe P. Chavanpun, MD, Dennis F. Bandyk, MD, Paul A. Armstrong, DO, Martin R. Back, MD, Brad L. Johnson, MD, Murray L. Shames, MD  Journal of Vascular Surgery  Volume 48, Issue 3, Pages (September 2008) DOI: /j.jvs Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

3 Fig 2 Kaplan-Meier estimates of primary (A) and assisted-primary (B) patency of 141 bypasses with abnormal first duplex scan and 212 bypasses with normal first duplex scan. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2008 The Society for Vascular Surgery Terms and Conditions

4 Fig 3 The number of secondary interventions performed during each postoperative time interval on bypasses with normal (n = 212) or abnormal (n =141) first duplex surveillance scan. During the follow-up period, 53 (25%) of 212 “normal” bypasses and 73 (52%) of 141 “abnormal” bypasses based on the first duplex scan were revised.
