Comparison Of Three Types Of Hemodialysis Vascular Access

Objective To evaluate three types of vascular access in hemodialysis patients, in order to select reasonable hemodialysis vascular access for patients.Methods Clinical data of675hemodialysis cases in our hospital from December1994to June2011were analyzed in patency、utility time and complications rate retrospectively.Results Patients with arteriovenous fistula were significantly higher than the other two groups in primary patency, assisted primary patency and secondary patency. Patients with arteriovenous graft were significantly higher than the central venous catheter in assisted primary patency and secondary patency after12months. The utility time of arteriovenous fistula was the best, the graft was the secondary and the central venous catheter was the last. Patients with arteriovenous fistula and graft respectively developed a total of0.24/py and0.91/py vs1.65/py complications in the central venous catheter. A total of0.66/py stenosis in the arteriovenous graft and0.17/py in the arteriovenous fistula, differences were statistically significant.Conclusions The construction of arteriovenous fistula is the primary and best option for vascular access for hemodialysis. In case of poor vessels maybe benefit from implantation of a graft for vas(?)ular access but central venous catheter should be avoided if possible.
