The coronary artery bypass conduit: II The coronary artery bypass conduit: II. Assessment of the quality of the distal anastomosis J.Alan Wolfe, MD The Annals of Thoracic Surgery Volume 72, Issue 6, Pages S2253-S2258 (December 2001) DOI: 10.1016/S0003-4975(01)03298-2

Fig 1 Graft flow measurement technique. Cardioplegic solution pumped through proximal end of graft at a mean pressure of 100 mg Hg after completion of distal anastomosis. I.D. = inside diameter; W.T. = wall thickness. The Annals of Thoracic Surgery 2001 72, S2253-S2258DOI: (10.1016/S0003-4975(01)03298-2)

Fig 2 Reversal of acidosis with establishment of flow through graft indicates adequate revascularization. CP = cardioplegic solution; LIMA = left internal mammary artery; OMB = obtuse marginal branch; XC = cross-clamp.

Fig 3 Technically adequate anastomosis. CP = cardioplegic solution; LAD = left anterior descending coronary artery; LIMA = left internal mammary artery; SVG = saphenous vein graft; top tracing = pH in the posterior LV wall; bottom tracing = pH in the anterior wall. The Annals of Thoracic Surgery 2001 72, S2253-S2258DOI: (10.1016/S0003-4975(01)03298-2)

Fig 4 Limited distal runoff caused by severe coronary artery vessel disease. CP = cardioplegic solution; LIMA = left internal mammary artery; XC = crossclamp. The Annals of Thoracic Surgery 2001 72, S2253-S2258DOI: (10.1016/S0003-4975(01)03298-2)
