Histopathological observations in (a,b) SG and (c,d) 3DT groups. (a–d) Representative images of H&E-stained aorta and surrounding tissue 30 days postoperation. Black arrow indicates SG graft: standard graft, ePTFE. Blue arrows indicate neovascularization. Red arrows denote advanced fibrosis. Small green dotted lines represent thrombosis; large green dotted lines suggest early fibrosis; green arrows indicate calcification. 3DT: 3D templated graft (magnification, 100× and 200×). (e) Histopathological score in SG and 3DT groups. Data are expressed as the mean ± standard deviation. * p < 0.05 compared with 7-day group.
