Modeling survival of arteriovenous accesses for hemodialysis: semiparametric versus parametric methods.
BACKGROUND AND OBJECTIVES Comparing outcomes of arteriovenous grafts and fistulas is challenging because the pathophysiology of access dysfunction and failure rate profiles differ by access type. Studying how risks vary over time may be important. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Longitudinal data from 535 incident hemodialysis patients were used to study the relationship between...
متن کاملProsthetic arteriovenous grafts for hemodialysis.
INTRODUCTION Prosthetic arteriovenous (AV) grafts are indicated in patients with failed AV fistula (AVF), exhausted superficial veins or unsuitable vessels. Increasing the proportion of prevalent hemodialysis (HD) patients using autogenous AVF should reduce the need for AV grafts and associated morbidity. This paper reviews the current role of prosthetic AV grafts in vascular access for HD. T...
متن کاملLipectomy as a new approach to secondary procedure superficialization of direct autogenous forearm radial cephalic arteriovenous accesses for hemodialysis.
BACKGROUND The depth of veins can discourage surgeons from creating radial-cephalic arteriovenous accesses for hemodialysis in obese patients. Elevation and tunneled transposition are the two techniques that have been described to superficialize these veins and make them accessible for cannulation. Unfortunately, such manipulation of veins has potential drawbacks. We report lipectomy, a new tec...
متن کاملتعیین میزان شیوع و بقاء روش‌های مختلف دستیابی عروقی در بیماران مبتلا به بیماری کلیوی مرحله انتهای (ESRD) تحت همودیالیز مزمن در تهران در سال 1384
Background and Aim: Hemodialysis is the most common procedure which is performed for end-stage renal disease (ESRD) patients. Furthermore, vascular access is an important aspect of hemodialysis treatment, provided for patients with ESRD. There are different reports on the prevalence and survival of vascular access. In this study we report the prevalence and survival probability of vascular ...
متن کاملClinical use of computational modeling for surgical planning of arteriovenous fistula for hemodialysis
BACKGROUND Autogenous arteriovenous fistula (AVF) is the best vascular access (VA) for hemodialysis, but its creation is still a critical procedure. Physical examination, vascular mapping and doppler ultrasound (DUS) evaluation are recommended for AVF planning, but they can not provide direct indication on AVF outcome. We recently developed and validated in a clinical trial a patient-specific c...
