Because the number of patients who require maintenance hemodialysis is increasing in number recently, angioaccess has become important to many vascular surgeons participating in the management of such patients.
The authors created 269 arteriovenous fistulas(AVF) for angioaccess in 229 patients with chronic renal failure(CRF) at the Department of Thoracic and Cardiovascular Surgery in Chungnam National University Hospital during the period from August
1990
to
March 1994. We analyzed the results of 260 operations for 220 patients except 9 patients who were lost during the follow up period.
We performed snuffbox AVF in 171 cases, classic radiocephalic AVF in 46 cases, direct AVF at other site in 5 cases, forearm Gore-Tex AVF in 29 cases, and upper arm Gore-Tex AVF in 9 cases.
We experienced 13 cases of operative failures, 11 cases of early complications, and 60 cases of late complications including obstructions during the follow-up period.
The 1 year, 2 year and 3 year patency rates of snuffbox AVF(Group 1), classic radiocephalic AVF (group 2), and Gore-Tex AVF(Group 3) are like followings; 89, 84, 76% in group 1, 84, 75, 68% in group 2, and 79, 66, 55% in group 3,. It showed a
statistically significant difference between group 1, 2 and group 3. (Korean J Thoracic Cardiovas Surg 1994; 27:669-76)
