چکیده
Purpose The aim of this study was to evaluate the flow volume and resistive index parameters of the brachial artery in the functioning and dysfunctioning radiocephalic and brachiocephalic hemodialysis arteriovenous fistula (AVF). Methods 82 patients were distributed into three groups according to their hemodialysis function - as normal function, decreased pump flow and increased venous pressure. Flow volumes and resistive indexes (RI) of the brachial artery of radiocephalic and brachiocephalic AVFs were measured by Doppler ultrasound. Flow parameters of the groups were compared. Results A statistically significant difference was found between the normal and decreased pump flow groups in terms of flow volume and resistive index values. 770 ml/min flow volume of the brachial artery has a 94% sensitivity and 84% specificity and 0.52 value of RI has an 89% sensitivity and 88% specificity in the the differentiation of normal and decreased pump flow groups. Conclusion Doppler parameters of the brachial artery such as flow volume and RI can provide valuable information about AVF function.

Background and purpose: Pulmonary hypertension (PH) has been reported in hemodialysis patients, but there are scant studies about its prevalence and mechanisms. The aim of this study was to determine the prevalence of pulmonary hypertension in hemodialysis patients and to study some of its possible etiologic factors. Materials and methods: Ïn this cross-sectional study, the prevalence of p...

INTRODUCTION The autogenous brachiocephalic fistula is a recognized secondary access for hemodialysis. However, veins in the antecubital fossa are often damaged, due to repeated venipunctures and subsequent scarring. Sometimes their anatomy does not enable successful arteriovenous fistula creation. In cases when the proximal part of the cephalic vein seemed patent, during ultrasound Doppler exa...

Background: Arteriovenous fistula is an important method for hemodialysis and prediction of fistula function and failure rate and access is crucial. This study was performed to determine the association between Doppler ultrasonography findings with function and failure and access rate of fistula. Methods: In this observational comparative cross-sectional study, out of 108 patients requiring fi...
متن کاملValidation of a patient-specific hemodynamic computational model for surgical planning of vascular access in hemodialysis patients.
Vascular access dysfunction is one of the main causes of morbidity and hospitalization in hemodialysis patients. This major clinical problem points out the need for prediction of hemodynamic changes induced by vascular access surgery. Here we reviewed the potential of a patient-specific computational vascular network model that includes vessel wall remodeling to predict blood flow change within...
