ABSTRACT
Objective To evaluate the effects of asymptomatic arteriovenous fistula closure on left ventricular morphology and function in renal transplant recipients.Methods Between March 2007 and March 2011,a total of 60 patients undergoing consecutive kidney transplantation with asymptomatic arteriovenous fistula were divided randomly into two groups: arteriovenous fistula closure group,and non-arteriovenous fistula closure group.By using echocardiography,the changes in CO,CI,EF,LVEDV and LVMI were analyzed.Results At 12th month after transplantation,the values of CO,LVEDV and LVMI were significantly lower than those before transplantation (P<0.05).The value of CI also showed a tendency to decrease (P>0.05),and the value of EF was increased significantly (P<0.05).At 6th month after arteriovenous fistula closure (18 months after transplantation),the values of CO,CI,LVEDV and LVMI were significantly lower than those before arteriovenous fistula closure (12 months after transplantation) (P<0.05),and the value of EF was increased significantly (P<0.05),but the values of CO,CI,EF,LVEDV and LVMI remained unc(b)anged in controls (P>0.05).At 18th month after transplantation,the values of CO (4.4 ±0.8 L/min),CI [3.0 ± 0.8 L·min-1·m-2],LVEDV (110.0 ± 17.4 ml) and LVMI (114.7 ± 42.5g/m2) in trial group were significantly lower than the values [CO: 5.1 ± 0.9 L/min,CI: 3.5 ± 1.0L·min-1·m-2,LVEDV: 121.4±19.3 mL,LVMI: 138.4±44.1 g/m2] in controls (P<0.05),and the value of EF (75.2% ± 7.4% vs.70.5% ± 8.2%) significantly higher (P<005).Conclusion In both groups,kidney transplantation benefits significantly the regression of cardiac mass,cardiac index and left ventricular dimensions,but closure of asymptomatic AVF induces more significant regression.
