人工血管移植动-静脉造瘘术的临床应用

目的 报道采用人工血管移植进行动－静脉造瘘术的临床应用效果。方法 １９９５年１０月～１９９８年８月,对２３例肾功能衰竭患者选择了膨体泡沫聚四氟乙烯（ＰＴＦＥ）人工血管进行前臂的动－静脉造瘘术。人工血管的直径为６ｍｍ,长４０ｃｍ。用Ｇｏｒｅ皮下隧道器分两次做皮下隧道,将人工血管一端从肘部切口引至腕侧切口后再引回肘部切口,形成Ｕ形袢管。用肝素盐水２０ｍｌ灌入血管腔内,人工血管两端分别与肘浅静脉及肘动脉

CLINICAL APPLICATION OF ARTIFICIAL BLOOD VESSLE GRAFT FOR ARTERIOVENOUS FISTULIZATION

OBJECTIVE: To investigate the clinical application of artificial blood vessel graft for arteriovenous fistulization. METHODS: From October 1995 to August 1998, 23 cases with renal failure received PTEF artificial vessels grafting for arteriovenous fistulization in the forearm. The PTFE artificial vessel was 6 mm in diameter, and 40 cm in length. Artificial vessel "U"-shaped loop was formed from elbow incision to wrist incision, and perfused by 20 ml heparin saline. The two ends of artificial vessel were end-to-side anastomosed with superficial cubital vein and cubital artery respectively. RESULTS: All of arteriovenous fistulas were successfully formed, and could be performed hemodialysis periodically. The artificial vessels could be punctured repeatedly, and had sufficient volume of blood flow. It had no rejection, no formation of false aneurysm, and no ischemia in arm or exacerbated reflux to heart. CONCLUSION: The artificial vessel grafting for arteriovenous fistulization is a safe and convenient technique in clinical practice, especially when there is no autogenous vessels for arteriovenous fistula.
