A computational study of viscoelastic blood flow in an arteriovenous fistula [PDF]

arXiv, 2020
A finite element analysis of flows of an Oldroyd-B fluid is developed, to simulate blood flow in an arteriovenous fistula. The model uses a combination of a standard conforming finite element approximation for the momentum equation, and the discontinuous Galerkin method, with upwinding, for the equation governing the evolution of the extra stress.

Kasabach-Merritt syndrome arising from an Enteroatmospheric Fistula [PDF]

arXiv, 2022
Kasabach-Merritt syndrome (KMS) is a rare, life-threatening condition that is characterized by profound thrombocytopenia, hypofibrinogenemia, elevated partial thromboplastin time, and may also be associated with microangiopathic hemolytic anemia. It is well established that this phenomenon is notably associated with the vascular tumors kaposiform ...

Immediate access arteriovenous grafts versus tunnelled central venous catheters: study protocol for a randomised controlled trial [PDF]

, 2015
Background Autologous arteriovenous fistulae (AVF) are the optimal form of vascular access for haemodialysis. AVFs typically require 6 to 8 weeks to “mature” from the time of surgery before they can be cannulated.

Endovascular Treatment of Malfunctioning Dialysis Fistulas: A Multicenter Retrospective Analysis Comparing Transradial and Conventional Transvenous Access

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Venous outflow is the favored access for endovascular management of dialysis fistulas. However, transradial access (TRA) offers advantages in specific clinical scenarios. The study aims to compare the efficacy, feasibility, and safety of TRA and transvenous access (TVA) in the endovascular management of malfunctioning dialysis ...

Lesões artério-venosas durais primárias intra-cranianas.

Acta Médica Portuguesa, 2003
Vascular lesions with arteriovenous shunts are a heterogeneous group of diseases composed of three distinct pathological entities: adult type dural arteriovenous fistula, dural sinus malformations with arteriovenous shunts and juvenile type of dural ...

High fidelity blood flow in a patient-specific arteriovenous fistula [PDF]

arXiv, 2020
An arteriovenous fistula, created by artificially connecting segments of a patient's vasculature, is the preferred way to gain access to the bloodstream for kidney dialysis. The increasing power and availability of supercomputing infrastructure means that it is becoming more realistic to use simulations to help identify the best type and location of a ...

A Clinical Prediction Score to Guide Referral of Elderly Dialysis Patients for Kidney Transplant Evaluation. [PDF]

, 2017
IntroductionDialysis patients aged ≥70 years derive improved life expectancy through kidney transplantation compared to their waitlisted counterparts, but guidelines are not clear about how to identify appropriate transplantation candidates. We developed

Safety and Efficacy of Single Femoral Vein Puncture Technique for Double Access in Patent Foramen Ovale Closure Under ICE Guidance—A Single Center Experience of the “Two‐In‐One Technique”

Catheterization and Cardiovascular Interventions, Volume 105, Issue 6, Page 1427-1433, May 1, 2025.
ABSTRACT Background In selected patient populations, percutaneous closure of patent foramen ovale has been shown to be beneficial in preventing cerebral ischaemic events. In most cases, this procedure requires echocardiographic guidance, which may be transesophageal, transthoracic or intracardiac.

Successful hand salvage with free flap reconstruction in a limb with arteriovenous fistula

JPRAS Open, 2017
Free flap reconstruction of a defect on an extremity with an arteriovenous fistula is a surgical challenge due to the unique hemodynamic characteristics of an arteriovenous fistula and its potential complications.
