钛轮钉建立动静脉内瘘的临床应用

目的:探讨钛轮钉建立动静脉内瘘手术方法和临床效果.方法:采用钛轮钉建立桡动脉与头静脉内瘘并长期维持透析的疗法,治疗终末期肾衰竭患者58例.结果:56例患者使用2.5 mm钛轮钉一次手术吻合成功,成功率96.6%,2例术中改为显微血管吻合术成功.术后内瘘未发生血管狭窄、栓塞,假性动脉瘤等并发症.结论:采用2.5 mm钛轮钉行桡动脉与头静脉吻合术是长期维持性血液透析患者建立动静脉内瘘的最佳手术方式;对于较细的血管宜采用显微外科血管吻合.

Clinical Application of Titanium Wheel Nail in the Establishment of Internal Arteriovenous Fistula

objective:To investigate the operative approach and clinical effect of titanium wheel nail in the establishment of internal arteriovenous fistula.Methods:58 patients with final stage of kidney failure were established internal arteriovenous fistula of radial artery and cephalic vein by means of titanium wheel nail,and kept hemodialysis for long.Results:56 of 58 patients obtained successful vascular anastomosis in first operation by using 2.5 mm titanium wheel nail,the achievement ratio was 96.6%.Other 2 cases had to be performed microabgio-anastomosis and got successful too.No postoperative complications,such as angiostegnosis,embolism and false aneurysm occurred in these internal arteriovenous fistulas.Conclusions:Anastomisis of radial artery and cephalic vein by using 2.5 mm titanium wheel nail is a best modus operandi to establish internal arteriovenous fistula in the patients who need long-term haemodialysis.But the subtile vascular anastomosis applied for microsurgery.
