1 Flow measurement before and after papaverine injection in above-knee prosthetic femoropopliteal bypass  Gustav Pedersen, MD, Elin Laxdal, MD, Svein Roar Amundsen, MD, Einar Dregelid, MD, Torbjørn Jonung, MD, PhD, Thomas Nyheim, MD, Steinar Aune, MD, PhD  Journal of Vascular Surgery  Volume 43, Issue 4, Pages (April 2006) DOI: /j.jvs Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

2 Fig 1 The primary assisted patency rates of 87 above-knee femoropopliteal prostheses. The numbers below the curve indicate the numbers at risk. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2006 The Society for Vascular Surgery Terms and Conditions

3 Fig 2 The distribution of intraoperative basal flow measurements in 87 above-knee prosthetic femoropopliteal bypass operations. The flow measurements are categorized as hundreds of milliliters per minute, rounding off downwards.

5 Fig 4 The primary patency rates of 59 grafts with a papaverine flow <500 mL/min and 28 grafts with a papaverine flow >500 mL/min. The numbers above and below the curves indicate the numbers at risk. The differences in patency rates are significant (P = .03, log-rank test). The median patency (time to reach 50% occlusion rate) for grafts with papaverine flow ≥500 mL/min is 48 months (SEM, 6.7; 95% confidence interval, 35 to 61). The median patency for grafts with papaverine flow <500 mL/min is 30 months (SEM, 4.3; 95% confidence interval, 21 to 38).
