摘　　要：目的:对两种不同结构的血管吻合用支架的溶解方式进行研究和比较,选择最合适的支架结构。方法:采用聚乙二醇20000(PEG20000)为原料制备不同结构的吻合用血管支架,分别观察其在体外检测模型内的溶解方式。结果:中空结构的吻合用支架具有不阻断血流、原位溶解、溶解速度快、用料少等特点,和实心结构支架相比具有明显优势。结论:中空支架和实心支架相比更适于血管吻合。In this paper, the solution modes of two stents with different structures are compared, and then one involved is elected as the optimum stent for anastomosis. Made of PEG20 000, two stents are solid and hollow respectively. The result proves that the hollow one, with the advantages of nonblocking bloodstream, undeflected and rapid solution, low requirement for raw materials, is fitter for anastomosis than the solid one.
