ABSTRACT
INTRODUCTION:
This study aimed to investigate the complication frequency and the changes in right heart geometry with different access types in the pediatric population.METHODS:
We included 32 consecutive patients aged between 10 and 19 and who underwent hemodialysis sessions via permanent hemodialysis catheter (nHC = 18) or arterio-venous fistula (nAVF = 14) between January 2013 and March 2018. We recorded and compared the complication frequency and the changes in echocardiography findings with different access types.FINDINGS:
Demographic data were similar in both groups. Number of new access creation (nHC = 15 vs nAVF = 1) and all complications (nHC = 19 vs nAVF = 6) were significantly higher in hemodialysis catheter group and the statistical analysis showed the superiority of arterio-venous fistula group in comparison of event-free survival (event-free patients; nAVF = 8 (57%), nHC = 3 (16%); p = 0.02). Control echocardiography showed impressive delta-change in right atrium diameter (p = 0.04), right ventricular end-diastolic volume (p = 0.004), right ventricular end-systolic volume (p < 0.001), and right ventricular free wall thickness (p = 0.009) in arterio-venous fistula group, but no significant difference between two groups in terms of delta-change of right ventricular ejection fraction (p = 0.35), fractional area change (p = 0.21), and tricuspid annular plane systolic excursion (p = 0.13) parameters.CONCLUSION:
Arterio-venous fistula has lower risk of complications, but overloading stress on right heart chambers triggers remodeling process and geometrical changes, which can be early pieces of evidence of delayed right heart dysfunction in pediatric hemodialysis patients.Palabras clave
