[Smooth intramural and kink-resistant polyester vascular prosthesis].
OBJECTIVE
To study the healing effect, neointimal formation and patency rate of smooth intramural and kink-resistant polyester vascular prosthesis.


METHODS
Experimental implantations of the smooth intramural and kink-resistant polyester vascular prosthesis of internal diameters of 0.6-1. Ocm were performed in segments of abdominal aorta and thoracic descending aorta.


RESULTS
The patency rate was 100% in both abdominal aortic implantations and thoracic descending aortic implantations after postoperative observation for 425 days, while the total patency rate was only 70% in the crimped controls. The thickness of the neointimal linings of both implantation groups was determined, smooth intramural, kink-resistant polyester vascular prostheses were significantly thinner than that using crimped polyester vascular grafts (P < 0.001).


CONCLUSIONS
Our study proves the feasibility of using smooth intramural and kink-resistant polyester vascular prosthesis to substitute small arteries with an internal diameter of 0.6-1. Ocm.
