The independent association of preoperative serum albumin on the functional maturation of radiocephalic arteriovenous fistulae

Abstract

Preoperative hypoalbuminemia (<35 mg/dL) is independently associated with 40% reduction in the functional maturation of RCAVF. Stratification of this readily available biomarker prior to RCAVF formation may require consideration subjected to further research.

Predictive Factors for Unsuccessful Use of Arteriovenous Fistula in a Population of End-Stage Renal Disease Patients in Southeastern Mexico

“…Low serum protein levels have been previously associated with poor AVF survival time, 14 and preoperative hypoalbuminemia (3.5 gr/dL) was previously demonstrated as a predictor for failure of AVF maturation in a study conducted by Kordzadeh et al 23 Malnutrition has been reported as an important risk factor for AVF failure in patients on HD. 24 We identified low serum albumin level as a predictive factor for FUHD use in both analyses (univariate and multivariate) and a regular performance in ROC analysis with a 3.3 gr/dL cutoff.…”

Independent association of arteriovenous ratio index on the primary functional maturation of autologous radiocephalic arteriovenous fistula

“…These have contributed to the creation of different risk predictors and scoring models; however, failure of primary FM secondary to thrombosis or stenosis remains an ongoing issue. [8][9][10][11][12] Recent evidence has shown that radial artery and cephalic vein diameters, irrespective of all factors, are independently associated with primary FM of RCAVFs. 13 The study by Browne et al 14 highlighted the subsequent impact of this paradigm on wall shear stress (WSS), remodeling process (positive or negative), endothelial cells, and extracellular matrix deposition.…”

Multifrequency Bioimpedance Phase Angle as a Tool to Predict Maturation Failure of Native Fistulae for Hemodialysis

“…The phase angle is considered to be a measurement of cellular stability and integrity that has a well-defined correlation with nutritional status and is considered to be an important predictor of survival in patients with chronic kidney disease compared with other traditionally used determinations such as DEXA (Dual energy X-ray absorptiometry assessment), global subjective evaluation and biochemical markers like total proteins and albumin; and its relation with mortality in this population has been described [21][22][23] (Figure 1). To this date only few studies have taken into account the relation between plasma albumin levels and adverse results related to arteriovenous fistulas, suggesting that low levels of plasma albumin could associate with failure of maturation of native fistulas [24,25]; however, considering that albumin is not an ideal marker for evaluating nutritional status in patients undergoing hemodialysis, its role as a tool helpful in predicting the probability of success or failure of a vascular access like an arteriovenous fistula is still unclear.…”
