1 Radiation arteritis: A contraindication to carotid stenting?
Clinton D. Protack, BS, Andrew M. Bakken, MD, Wael A. Saad, MD, Karl A. Illig, MD, David L. Waldman, MD, PhD, Mark G. Davies, MD, PhD  Journal of Vascular Surgery  Volume 45, Issue 1, Pages (January 2007) DOI: /j.jvs Copyright © 2007 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Freedom from restenosis. Sixteen (13%) patients with atherosclerotic occlusive disease (ASOD) and 10 patients (43%) with radiotherapy-induced (XRT) arteritis restenosed (P < .05). The 3-year rates for freedom from restenosis were 74% for ASOD and 20% for XRT. Error bars are omitted for clarity. The number of procedures at risk at each time interval is shown below the figure. The standard error did not exceed 10% at all time intervals that were analyzed. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2007 The Society for Vascular Surgery Terms and Conditions

3 Fig 2 Freedom from restenosis, assisted. One patient with atherosclerotic occlusive disease (ASOD) and three patients with radiotherapy-induced (XRT) arteritis underwent reintervention. Restenosis rates remained significantly different between the two groups. Error bars are omitted for clarity. The number of procedures at risk at each time interval is shown below the figure. Standard error did not exceed 10% at all time intervals that were analyzed. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2007 The Society for Vascular Surgery Terms and Conditions

4 Fig 3 Vessel patency. No patient (0%) with atherosclerotic occlusive disease (ASOD) and two patients (8.6%) with radiotherapy-induced (XRT) arteritis occluded postoperatively (P < .05). The 3-year rates for freedom from occlusion were 100% for ASOD and 79% for XRT. Error bars are omitted for clarity. The number of procedures at risk at each time interval is shown below the figure. Standard error did not exceed 10% at all time intervals that were analyzed. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2007 The Society for Vascular Surgery Terms and Conditions

5 Fig 4 Freedom from recurrent symptoms. Twenty patients (16%) with atherosclerotic occlusive disease (ASOD) four patients (17%) with radiotherapy-induced (XRT) arteritis experienced recurrent symptoms postoperatively (P = NS). Error bars are omitted for clarity. The number of procedures at risk at each time interval is shown below the figure. Standard error did not exceed 10% at all time intervals that were analyzed.

6 Fig 5 Patient survival. One patient (1%) with atherosclerotic occlusive disease (ASOD) and two (9%) with radiotherapy-induced (XRT) arteritis died during follow-up (P = NS). Error bars are omitted for clarity. The number of procedures at risk at each time interval is shown below the figure. Standard error did not exceed 10% at all time intervals that were analyzed.
