Histological and histomorphometry evaluation of the implanted synthetic grafts after 2 weeks of implantation. H&E staining of the midsection of NanoGraft a entire graft Sect. (1.25×) b cell lining on the luminal surface of NanoGraft (depicted by red arrows) c abluminal surface of the graft with a minimal inflammatory response). d–e H&E staining of the midsection of ePTFE grafts d entire graft Sect. (1.25×) e cell lining on the luminal surface of ePTFE (depicted by red arrows) f abluminal surface of the graft with high inflammatory cells g Neointimal area h Percentage of graft stenosis and i Transluminal wall thickness, of the implanted synthetic grafts. Statistical significance between the two groups was assessed using a paired t-test. Error bars represent standard deviation. P-value of each comparison is depicted in the plot
