1 Changing pattern of surgical revascularization for critical limb ischemia over 12 years: Endovascular vs open bypass surgery  Toshifumi Kudo, MD, PhD, Fiona A. Chandra, BS, Woo-Hyung Kwun, MD, PhD, Bradley T. Haas, Samuel S. Ahn, MD  Journal of Vascular Surgery  Volume 44, Issue 2, Pages (August 2006) DOI: /j.jvs Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 Trends of primary and subsequent procedures. The number of procedures in each time period are shown. P values were calculated with the χ2 test. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

3 Fig 2 Trends in combinations of primary and subsequent procedures performed in each limb during the follow-up. The number of combinations—primary endo with or without subsequent endo (endo alone), primary open bypass surgery with or with out subsequent open (open alone), or primary endo followed by subsequent open or primary open followed by subsequent endo (both) in each time period are shown. P was calculated via the Mann-Whitney U test. Endo, Angioplasty with or without stenting; open, bypass surgery and/or patch angioplasty.

4 Fig 3 Kaplan-Meier life-table analysis of outcomes for critical limb ischemia in each study period (54 limbs in 1993 to 1996, 79 in 1997 to 2000, and 104 in 2001 to 2004). A, Primary patency. B, Assisted primary patency. C, Continued clinical improvement. The assisted primary patency rates were significantly higher in 2001 to 2004 compared with those in 1993 to1996 and 1997 to 2000 (P = .012). The dashed line is the portion of plot where the standard error (SE) >10%. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

5 Fig 4 Kaplan-Meier life-table analysis of outcomes for critical limb ischemia in the endo group (n = 153) and the bypass group (n = 84). A, Primary patency. B, Assisted primary patency. C, Continued clinical improvement. The assisted primary patency rates were significantly higher in the endo group compared with those in the bypass group (P = .0001). The dashed line is the portion of plot where standard error (SE) >10%. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

6 Fig 5 Kaplan-Meier life-table analysis of the assisted primary patency rates in patients with tibial occlusive disease. There were 55 in the tibial-endo group and 41 tibial-bypass group. There was a statistical difference between the two groups (P = .041). The dashed line is the portion of plot where standard error (SE) >10%.
