1 The impact of sequential versus single anastomoses on flow characteristics and mid- term patency of saphenous vein grafts in coronary bypass grafting  Hee Jung Kim, MD, Taek Yeon Lee, MD, Joon Bum Kim, MD, Won Chul Cho, MD, Sung Ho Jung, MD, Cheol Hyun Chung, MD, Jae Won Lee, MD, Suk Jung Choo, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 141, Issue 3, Pages (March 2011) DOI: /j.jtcvs Copyright © 2011 The American Association for Thoracic Surgery Terms and Conditions

2 Figure 1 Relationship between hemodynamic flow characteristics and number of distal anastomoses per graft. A, Mean flow versus the number of anastomoses per graft shows a direct linear relationship (P < .001). B, Inverse relationship is shown with the PI (P = .02). Bar represents mean value and 95% CI.

3 Figure 2 Correlation between mean flow and logarithmic transformation of PI values (Ln PI). Correlation coefficient = −0.43, P = 001. The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /j.jtcvs ) Copyright © 2011 The American Association for Thoracic Surgery Terms and Conditions

4 Figure 3 Comparison of freedom from graft failure. The solid line represents group A (sequential bypass graft), and the dotted line represents group B (individual bypass graft). Note that group A shows superior freedom from graft failure compared with group B (P = .048).
