Assessment of Vein Intima-Media Thickness in Determining Maturity of AV Fistula
Journal Title: Journal of Medical Science And clinical Research - Year 2016, Vol 4, Issue 11
Abstract
Vascular access is a hemo-dialysis patient’s lifeline. Two types of permanent vascular access are designed which include the arterio-venous fistula and the arterio-venous graft. After surgical creation, arteriovenous fistulas typically require several months of maturation for the draining vein to dilate and the arterio-venous blood flow to increase. The criteria for AV fistula maturation is vein diameter of 4 mm and access blood flow volume of 500 ml/min by using Doppler. Here we assess the intima-media thickness of the vein in determining maturity of AV fistula. Purpose- To determine cannulation readiness of AV fistula by determining vein intima-media thickness. Materials and methods- Institutional review board approval and informed consent were obtained for this study. The study is a cross-sectional study at our hospital tertiary health care set up. Statistical Analysis – A Chi-square test is used to find an association between variables (gender, diabetic and hypertensive status). Results and Conclusion- The conclusions drawn are those cases with intima-media thickness </= 0.20 mm are not matured, while those cases with intima-media thickness >/=0.26mm were matured and those cases with intima-media thickness between 0.21-0.25mm were matured only by vein diameter.
