A patient-specific FSI model for vascular access in haemodialysis
… improve the understanding of haemodynamics and vascular mechanics in arteriovenous shunting. To achieve the high flow rates that enable patients with renal disease to receive haemodialysis, a fistula is created between an artery and a vein. The patency rate of fistulas, especially those located …

Αιμοδυναμική μελέτη της ταυτόχρονης δημιουργίας εξωτερικής (shunt) & εσωτερικής (fistula) αρτηριοφλεβικής επικοινωνίας στα μηριαία αγγεία σκύλου: Πειραματική εργασία
… Intermitent Hemodialysis the two main methods of vascular access are discussed. These two methods are: a) The "shunt" or external arterio-venous (Αν) communication and b) The "Fistula" or internal A-V communication. Following this, the basic principles that govern the blood flow in the vessels are …

Audit of acute limb ischaemia in a paediatric intensive care unit
… patients is a well-recognised complication of vascular access. This retrospective review of a paediatric intensive care unit identified patients who developed iatrogenic acute limb ischaemia between January 2008 and July 2013. Methods: The medical records of inpatients diagnosed with acute limb …

Patient-specific computational haemodynamics in the arteriovenous fistula and aorta of a chronic kidney disease cohort
… Haemodialysis, the most common RRT, requires a vascular access for an efficient and repeatable procedure. An arteriovenous fistula (AVF) is widely considered the ‘gold-standard’ vascular access. However, AVFs suffer from poor patency rates, and their non-maturation is a key issue in failing …

ROLE OF CKD AND CASPASE-1 IN NEOINTIMAL HYPERPLASIA DEVELOPMENT
Vascular access dysfunction is a cause of morbidity and mortality in chronic kidney disease (CKD) patients that require hemodialysis. The major cause of vascular access failure is venous stenosis due to neointimal hyperplasia (NH). Vascular smooth muscle cells (VSMC) are critical for the …

Midline Catheter Usage in the Neonatal Population
… for evidence-based practices when selecting a vascular access device (VAD). Literature reviewed demonstrated that a midline catheter (MC) was an option for a VAD with neonatal populations requiring antibiotic therapy more than 48 hours. MCs offer fewer complications compared to the peripheral …

Giving birth to a new approach: a retrospective comparison of radiation safety parameters between transradial and transfemoral approaches for uterine fibroid embolization at Groote Schuur Hospital, South Africa
… leiomyomas. The conventional transfemoral access (TFA) in UAEs remains the method of choice for the majority of South African interventional radiologists. Transradial access (TRA) has grown as a viable alternate vascular access. The advantages of TRA over TFA have been well documented, …

Flow velocity measurement in haemodialysis access using 4D MRI
… renal failure while awaiting transplant requires vascular access, which comes with both complications and failure rates. In order to improve this, information about the AVF or AVG itself, as well as the haemodynamics is required. This data will then be used for computer modelling techniques and …

Incidence of Steal Phenomena and Steal Syndrome in Patients with Arteriovenous Fistulae
… to identify patients at risk of arteriovenous access ischaemic steal? 2. Is it possible to reduce reported rates of steal and steal phenomena in autogenous fistulae located at the antecubital fossa by modifying the arterial inflow used? 3. Should elderly patients initiating haemodialysis be …

Fluid-structure interaction modelling of a patient-specific arteriovenous access fistula
… detailed understanding of the haemodynamics and vascular mechanics in arteriovenous shunts that are required for haemodialysis treatments. A combination of new PCMRA imaging and computational modelling of in vivo blood flow aims to determine the haemodynamic conditions that may lead to the high …

Record review of post-haemodialysis blood results to assess adherence to guidelines for end stage renal disease
… public healthcare sector limits patients' access to renal replacement therapy: here 14.8% are on haemodialysis compared to 85.2% in private dialysis units. Quality indicators in internationally accepted guidelines address complications of End Stage Renal Disease for patients on …
