Computational analysis for competition flows in arteriovenous fistulas based on non-contrast magnetic resonance imaging [PDF]
arXiv, 2023 Introduction: Characteristics of hemodynamics strongly affect the patency of arteriovenous fistula (AVF) in hemodialysis patients. Because of pressure balance changes among arteries after AVF construction, regurgitating flow occurs in some patients.

Outcome of open excisional breast biopsies in Abakaliki, South-East Nigeria
The Pan African Medical Journal, 2018 INTRODUCTION: open excisional breast biopsy is a known modality for treatment of breast lumps especially in developing countries. Other sophisticated methods are available for management of breast lumps in more advanced nations. Our aim in this study was

Effect on the canine Eck fistula liver of intraportal TGF‐β alone or with hepatic growth factors [PDF]
, 1992 Transforming growth factor‐β canceled the hepatocyte proliferation caused by transforming growth factor‐α when the two substances were mixed and administered through a disconnected central portal vein branch after creation of an Eck fistula. In contrast,

Recent advances in the diagnosis and treatment of complex anal fistula [PDF]
Annals of ColoproctologyAnal fistula can be a challenging condition to manage, with complex fistulas presenting even greater difficulties. The primary concerns in treating this condition are a risk of damage to the anal sphincters, which can compromise fecal continence, and ...

Deep Learning for Needle Detection in a Cannulation Simulator [PDF]
arXiv, 2021 Cannulation for hemodialysis is the act of inserting a needle into a surgically created vascular access (e.g., an arteriovenous fistula) for the purpose of dialysis. The main risk associated with cannulation is infiltration, the puncture of the wall of the vascular access after entry, which can cause medical complications.

Fluid-structure interaction modelling and stabilisation of a patient-specific arteriovenous access fistula [PDF]
, 2017 A patient-specific fluid-structure interaction (FSI) model of a phase-contrast magnetic resonance angiography (PC-MRA) imaged arteriovenous fistula is presented. The numerical model is developed and simulated using a commercial multiphysics simulation package where a semi-implicit FSI coupling scheme combines a finite volume method blood flow model and
