Evaluation of the patency and luminal diameter of explanted grafts at 3 months after implantation. (A) The patency was measured by color Doppler ultrasound. (B) The patency rates of the PCL and PCL/PDS grafts at both time points. (C) The lumen of the explanted grafts was smooth and free of thrombus under stereomicroscope. (D) Cross sections were stained with H&E to identify the neointima formation. (E) Representative H&E staining of longitudinal sections of explanted grafts. (F) The luminal diameter of explanted grafts was calculated based on the cross sections with H&E staining. (L) lumen; Red arrows: suture site. *p < 0.05.
