Outcomes of post-operative duplex ultrasound following arteriovenous fistula formation: A pragmatic single-centre experience.

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 and 'standard practice'. RESULTS: Two hundred forty-one arteriovenous fistulae were created in 216 patients. A higher proportion of brachiobasilic transposition arteriovenous fistula and patients undergoing arteriovenous fistula creation following a previously failed access were identified in the duplex ultrasound surveillance group. Primary patency at 12 months (hazard ratio = 0.43, 95% confidence interval = 0.30-0.61, p

Preoperative ultrasound vessel mapping is a crucial step in operative planning for permanent hemodialysis access creation. Whereas the majority of the focus remains on vein caliber, anatomic arterial variants are often overlooked. Despite being a relatively common variation, little is known about the impact of a high brachial bifurcation on hemodialysis access outcomes. Our goal was to examine the relationship between a high brachial bifurcation and arteriovenous fistula (AVF) maturation and patency in patients undergoing upper arm hemodialysis access placement.

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...

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 ...
