1 Histomorphologic superiority of internal thoracic arteries over right gastroepiploic arteries for coronary bypass  Tomohiro Nakajima, MD, Kazutoshi Tachibana, MD, Nobuyuki Takagi, MD, Toshiro Ito, MD, Nobuyoshi Kawaharada, MD  The Journal of Thoracic and Cardiovascular Surgery  Volume 151, Issue 6, Pages (June 2016) DOI: /j.jtcvs Copyright © Terms and Conditions

3 Figure 2 Gastroepiploic artery (GEA) specimens from 2 different patients. A, GEA with concentric nonatheromatous intimal thickening (Elastica van Gieson stain; original magnification, ×40). This patient was a 52-year-old man with hypertension and hyperlipidemia; his glycated hemoglobin (HbA1c) concentration was 5.4%. B, Normal GEA. The intima is a very thin layer consisting mainly of endothelium (Elastica van Gieson stain; original magnification, ×40). This patient was a 70-year-old woman with diabetes, smoking, hypertension, and hyperlipidemia; her HbA1c was 6.6%.

4 Figure 3 Three histopathologic specimens from 1 patient. This patient was a 60-year-old man with hypertension and hyperlipidemia; his glycated hemoglobin (HbA1c) was 6.0%. A, Gastroepiploic artery (GEA) with moderate concentric nonatheromatous intimal thickening. B, Normal left internal thoracic artery (LITA). The intima is a very thin layer consisting mainly of endothelium resting on the internal elastic lamina. C, Normal right internal thoracic artery (RITA). The intima is very thin (Elastica van Gieson stain; original magnification, ×40). The Journal of Thoracic and Cardiovascular Surgery  , DOI: ( /j.jtcvs ) Copyright © Terms and Conditions

5 Figure 4 Scatter plot of intimal width of the left internal thoracic artery (LITA), right internal thoracic artery (RITA), and gastroepiploic artery (GEA). The GEA is variously scattered, and the intimal thickness increases in parallel with the glycated hemoglobin (HbA1c) concentration, whereas the intima of both internal thoracic arteries does not.
