Snaring of the Target Vessel in Less Invasive Bypass Operations Does Not Cause Endothelial Dysfunction Louis P Perrault, Philippe Menasché, Jean-Pierre Bidouard, Christine Jacquemin, Nicole Villeneuve, Jean-Paul Vilaine, Paul M Vanhoutte The Annals of Thoracic Surgery Volume 63, Issue 3, Pages 751-755 (March 1997) DOI: 10.1016/S0003-4975(96)01118-6 Copyright © 1997 The Society of Thoracic Surgeons Terms and Conditions

Fig. 1 Definition of the four segments of the left anterior descending coronary artery studied in the experimental protocol. (LAD = left anterior descending artery; LCX = left circumflex artery.)

Fig. 2 Cumulative concentration-relaxation curves to serotonin in rings of porcine left anterior descending coronary arteries with endothelium submitted to proximal snaring (n = 5, squares), the anastomotic site submitted to 30 minutes of ischemia and 30 minutes of reperfusion (n = 5, triangles), distal snaring (n = 5, diamonds), and control (n = 5, circles). Responses are given as a percentage of relaxation to the contraction induced by prostaglandin F2α (PGF2α). Results are presented as mean ± standard error of the mean. (5-HT = 5-hydroxytryptamine.)
