Purpose: Active venous mapping by ultrasonography much increased the rate of autologous graft operations while significantly decreasing the rate of maturation failures. Reports on this phenomenon, however, have been rare in Korea. We here the effect of venous mapping by ultrasonography.
Methods: From 2005.1 to 2006.6, we selected 73 patients with autologous or artificial vessel or tunneled catheter and put them into 2 groups: the group that had operation after venous mapping by ultrasonography (n=40) and the control group (n=33) and rate of autologous vessels and the frequency and cause of maturation failure were analysed retrospectively.
Results: Patient’s age, patient ratio of age, DM ratio in the map group against the control group were respectively 58.95±19.93 (25-86) vs 60.76±11.93 (39-80), 20/40 vs 17/33, 14/40 vs 19/33 showing no signficant differences between them. Gender ratios (M/F) were 12/28 vs 21/12 showing more females in the mapping group. As for the rate of autologous vessel, 34 out of 40 in map group, and 31 out of 33 in the control group showed no significant difference. After the first operation, 36 out of 40 in map group and 16 out of 33 in the control group were using autologous vessel. The map group had tendency to use higher rate of autologous vessels than the control group (p=0.059). MF ratio was significantly low in the mapping group (p=0.000).
Conclusion: Carrying out preoperative venous mapping would promote development of appropriate techniques, together with increased use of autologous vessels. It is also thought that MF reduced the chance of reoperation.
