应用医用胶和可溶性小血管支架粘接小动脉的实验研究

Anastomosis of small artery using ZT medical adhesive and soluble stent

常规间断缝合法吻合小血管难度大,需时长。我们应用国产医用胶和可溶性小血管支架法粘接兔小动脉的实验研究,只需在12点、6点处缝合两针,置入小血管支架,将两断端严密对齐,吻合口处涂布医用胶,待胶固化后,吻合便告完成,操作简便,省时。远期通畅率、吻合口的修复过程与间断缝合法相比较,基本一致。

The conventional technique of interrupted suture in microvascular anas- tomosis is difficult to perform and timeconsuming.A new method with ZT medical adhe- sive and soluble intravascular stent is introduced.Using this method,end-to-end anasto- mosis of small arteries could be performed easily and quickly.Both the patency rate and histopathologic changes at the anastomosis sites were examined.In comparison with su- ture technique,similar patency rate was obtained.Inflammatory reaction in mid and out- er layers of the vessel was observable and reendothelialization of the intima was identi- cal.
