Correlation of vascular stenosis with hemodialysis parameters in native arterio-venous fistula (AVF), pre and post percutaneous transluminal angioplasty (PTA)

| description | Introduction: Stenosis and thrombosis of Arterio-Venous Fistula (AVF) has been an ongoing
problem in hemodialysis patients. Early treatment by Percutaneous Transluminal Angioplasty
(PTA) helps in maintaining AVF patency. However, how much PTA would improve the
hemodialysis function was still questionable and only few literatures discussed on this matter.
Hence, we performed a study on “Correlation of Vascular Stenosis with Hemodialysis
Parameters in Native Arteriovenous Fistula (AVF), Pre and Post Percutaneous Transluminal
Angioplasty”.
Objective: To determine association between percentage of residual stenosis with
hemodialysis success.
Methodology: A total of 47 patients underwent Percutaneous Transluminal Angioplasty
(PTA) in AMIEN Unit HUSM from June 2014 till October 2015; 14 were excluded and 19
lost to follow up leaving 14 subjects to study. All measurements of stenosis diameter were
made from the PACS system whereas hemodialysis parameters were gathered through phone
call to the subjects’ regular hemodialysis centre.
Results: This study has revealed a weak correlation between percentage of stenosis with
blood pump flow rate (Qb) in pre and post PTA. No correlation between percentage of
stenosis with venous dialysis pressure (Vp) in pre and post PTA. The achieved technical
success was 57.1% (P = 0.001).
Conclusion: There is weak correlation between degree of stenosis with blood pump flow rate
(Qb) but not observed in venous dialysis pressure (Vp). |
