摘　　要：用分子量20 000的高纯度聚乙二醇制成浅蓝色可溶性血管内支架,用于辅助小血管的缝合。在24例家兔股动脉缝合实验中,缝合一根小血管的时间为5～7分钟。缝合完毕后,支架在血流中10～15分钟(平均12分钟)内完全溶解,即时通畅率100％,起到理想的力学支撑作用,提高了缝合质量和速度,从根本上避免了错缝到对侧血管壁的可能性。对于缝合小血管操作不够熟练的医生更有益处。这种新型血管内支架制作工艺成熟,很容易转入临床应用。A new soluble intravascular stent was made from polyethylene glycol-20 000(PEG-20 000) and 24 rabbits femoral arteries were anastomosed supporting with the stent. The performing time of anastomosis was between 5 ~ 7min. The blue stent was solved in blood stream within 10~15min, after finishing a patency rate of 100%.
