Patient-Specific Computational Modeling of Upper Extremity Arteriovenous Fistula Creation: Its Feasibility to Support Clinical Decision-Making
INTRODUCTION Inadequate flow enhancement on the one hand, and excessive flow enhancement on the other hand, remain frequent complications of arteriovenous fistula (AVF) creation, and hamper hemodialysis therapy in patients with end-stage renal disease. In an effort to reduce these, a patient-specific computational model, capable of predicting postoperative flow, has been developed. The purpose ...
متن کاملRisk factors predicting the successful function and use of autogenous arteriovenous fistulae for hemodialysis.
BACKGROUND For patients with end-stage renal failure hemodialysis with an autogenous arteriovenous fistula (AVF) has proven to be the ideal vascular access. OBJECTIVE The aim of this study is to discover potential predictors of a well-functioning hemodialysis fistula. METHODS From December 2009 to March 2011, 80 patients undergoing first time AVF creation were enrolled in our retrospective ...
متن کاملTwo Approaches to the Initial Transient Problem
This paper describes two diierent approaches to dealing with the initial transient problem. In the rst approach, the length of the \warm-up period" is determined by obtaining analytical estimates on the rate of convergence to stationarity. Speciically, we obtain an upper bound on the \second eigenvalue" of the transition matrix of a Markov chain, thereby providing one with a theoretical device ...
متن کاملSimplified phosphorus kinetic modeling: predicting changes in predialysis serum phosphorus concentration after altering the hemodialysis prescription.
BACKGROUND The KDIGO work group recommends increasing dialytic phosphorus removal in Stage 5D chronic kidney disease patients with persistent hyperphosphatemia; however, optimal prescriptions to enhance phosphorus removal by hemodialysis (HD) therapies have not yet been established. This study evaluated whether phosphorus kinetic modeling based on a pseudo one-compartment model could provide pr...
متن کاملIschemic Monomelic Neuropathy after a Brachio-Cephalic AVF Creation: A Case Report and Review of Literature
Ischemic monomelic neuropathy (IMN) is an under-diagnosed and disabling complication of upper extremity hemodialysis access. The hemodynamic disturbance that occurs during the time of access creation can lead to both neurologic and ischemic complications. These complications are most commonly seen following proximal procedures involving the upper limbs. Diagnosis and treatment are often delayed...
