FIG. 3.

Graft diameter, blood flow rate, and puncture under ultrasound guidance. Ultrasound images of nanofiber TEVGs (A, C) and ePTFE grafts (B, D) at 2 weeks (A, B) and 4 weeks (C, D) after surgery. (E, F) Lumen diameter and blood flow rate of TEVGs versus ePTFE grafts. Asterisk indicates statistical significance between the two groups (p < 0.05). (G, H) Successful needle puncture of grafts at 4 weeks after AV shunt surgery under ultrasound guidance. Arrows refer to the needle within the grafts.
