Natural Vascular Remodelling After Arteriovenous Fistula Creation in Dialysis Patients With and Without Previous Ipsilateral Vascular Access.

CONCLUSION: Arteriovenous fistulae show haemodynamic and remodelling changes up to three months post-operatively. Previous ipsilateral VAs may initiate vessel preconditioning, and accelerate the observed haemodynamic changes after AVF creation. However, this preconditioning does not result in a beneficial or detrimental effect on VA function. PMID: 31911136 [PubMed - as supplied by publisher]

We describe the successful use of EUS-FNA in a peritoneal dialysis (PD) patient to evaluate a pancreatic cyst. The patient continued on PD immediately after the procedure without using hemodialysis. The patient did not experience any complication such as infection, bleeding, or peritoneal fluid leakage. PMID: 32063184 [PubMed - as supplied by publisher]

Authors: Kaptein MJ, Kaptein JS, Nguyen CD, Oo Z, Thwe PP, Thu MB, Kaptein EM Abstract Cardiac output may increase after volume administration with relative intravascular volume depletion, or after ultrafiltration (UF) with relative intravascular volume overload. Assessing relative intravascular volume using respiratory/ventilatory changes in inferior vena cava (IVC) diameters may guide volume management to optimize cardiac output in critically ill patients requiring hemodialysis (HD) and/or UF.We retrospectively studied 22 critically ill patients having relative intravascular volume assessed by IVC Collapsibility ...

ConclusionsDrug-coated balloon angioplasty resulted in superior survival of dysfunctional peripheral vascular access at 6 and 12  months, but this result was not statistically significant. Both arms show equivalent complications and similar mortality.Level of EvidenceLevel Ia, therapeutic study, RCT. EBM ratings will be based on a scale of 1-5.

CONCLUSION: The technique described allows elevation of the vein to the level of the dermis without division and re-anastomosis or re-tunneling, through several small incisions maintaining virgin skin and normal contour for easier cannulation. PMID: 31992105 [PubMed - as supplied by publisher]

Abstract Since the amount of contrast media during percutaneous coronary intervention (PCI) is closely related to the exacerbation of renal function, it should be important to reduce the dose of contrast media during PCI. The purpose of this retrospective study was to evaluate the association of less-contrast media with clinical factors in elective PCI. A total of 709 patients were divided into the less-contrast media group (n = 142) and the conventional-contrast media group (n = 567) according to the quintile of total contrast volume. Univariate and multivariate logistic regression analyses w...

OBJECTIVE AND METHODS: We investigated the effect modification by systemic inflammation (serum CRP) on the relationship between a...

Macaulay Amechi Chukwukadibia Onuigbo, Nneoma Agbasi, Bibek Sarki, Sana Khan, Kramer WahlbergIndian Journal of Nephrology 2020 30(1):29-31 Internal jugular vein (IJV) cannulation was originally described by English et al. in 1969 as the safest approach. Carotid artery puncture had an incidence rate of 4–6% before ultrasound guidance. We encountered an unexpected sequence of events following the ultrasound-guided placement of a temporary HD catheter in the left IJV. The postprocedure chest radiograph was misinterpreted as an arterial misplacement, the blood return was correspondingly bright red, and simultaneous ...

Authors: Colucci M, Torreggiani M, Bernardi I, Stangalino S, Catucci D, Esposito V, Sileno G, Esposito C Abstract BACKGROUND: Smart Flow is an innovative tool available on the Carestream Touch Prime Ultrasound machines, which provides automated blood flow measurement and shows the vectors that form the blood flow in the vessel. We compared the use of Smart Flow with traditional Duplex Doppler Ultrasound to evaluate blood flow of arteriovenous fistulas in prevalent hemodialysis patients. METHODS: A total of 31 chronic patients on hemodialysis were enrolled. Blood flow was measured on the brachial artery with Sma...

This study aims to determine whether post-operative duplex ultrasound surveillance can improve fistula patency at 12 months and improve the proportion of 'pre-haemodialysis' patients commencing haemodialysis via a usable fistula. METHODS: All arteriovenous fistulae formed between 1st January 2015 and 31st August 2017 in a single, tertiary vascular centre were included. Primary and secondary patency at 12 months, along with the proportion of pre-haemodialysis patients commencing haemodialysis via a usable arteriovenous fistula, were compared between the fistulae undergoing duplex ultrasound surveillance an...
