Fig. 8From: Peripheral nerve defects repaired with autogenous vein grafts filled with platelet-rich plasma and active nerve microtissues and evaluated by novel multimodal ultrasound techniquesHigh-frequency nerve ultrasound examination was performed at 2 weeks and 12 weeks after operation. A High-frequency ultrasound images of the nerve graft on the surgical side. Statistical analyses were performed by calculating the thickness of the nerve graft at B 2 weeks and C 12 weeks. D Comparison of nerve graft thickness at different time points. **P < 0.01, and n.s. not significant. Micro-T microtissues, PRP platelet-rich plasmaBack to article page
