Figure 2: Comparison between TEVG implantation to sham group. A TEVG was made of biodegradable electrospun polylactic acid (PLA) nanofibers (length=3mm; inner luminal diameter 500-600 μm). B implantation of TEVG. The image shows inferior vena cava (IVC) and aorta (Ao). C Survival rate at 24 hours after surgery. < 10% of mice implanted with TEVG died within 24 hours after TEVG implantation because of bleeding or thrombosis. D Kaplan-Meier survival curve considering the 12 months of experiment. No significant statistical difference was highlighted between the two groups.
