Proposal of a classification of cannulation damage in vascular access grafts based on clinical, ultrasound, and microscopic observations
CONCLUSION: Cannulation damage alone does not solely account for AVG failure. It results from a biological host-mediated process that promotes the growth of intimal hyperplasia at the cannulation sites. This process is not clinically significant within the initial 2 years after AVG creation.PMID:38679815 | DOI:10.1177/11297298241248263 (Source: The Journal of Vascular Access)

The association between vascular access satisfaction and all-cause mortality in maintenance hemodialysis patients
J Vasc Access. 2024 Apr 29:11297298241244483. doi: 10.1177/11297298241244483. Online ahead of print.ABSTRACTBACKGROUND: The mortality is significantly higher in patients undergoing maintenance hemodialysis (MHD) than in the general population. It is well-known that vascular access (VA) is critical for MHD patients. But the association between VA satisfaction and all-cause mortality in MHD patients is still not clear. The aim of this study was to explore the relationship between VA satisfaction and all-cause mortality in MHD patients with a 30-month follow-up.METHODS: Two hundred twenty-nine MHD patients in two dialysis cen...

Interventions to manage occluded central venous access devices: An umbrella review
J Vasc Access. 2024 Apr 24:11297298241246092. doi: 10.1177/11297298241246092. Online ahead of print.ABSTRACTThe main objective of this umbrella review is to synthesise available evidence from systematic reviews on the effectiveness of interventions for the management of occlusions in central venous access devices. CVADS have been extensively utilised among the critically ill since the 1950s however have also been linked to an increase in catheter complications. CVAD occlusion can occur in 14%-36% of patients within 1-2 years of catheter placement and is a longstanding complication. Umbrella methodology was applied to revie...

A systematic review of prediction models on arteriovenous fistula: Risk scores and machine learning approaches
CONCLUSION: The performance of existing predictive models for AVF maturation/patency is underreported. They showed satisfactory performance in their own study population. However, there was high risk of bias in methodology used to build some of the models. The reviewed models also lack external validation or had reduced performance in external cohort.PMID:38658814 | DOI:10.1177/11297298241237830 (Source: The Journal of Vascular Access)

Tongue patch angioplasty for small-caliber vein segments directly connected to juxta-anastomotic stenosis
This study introduces a surgical method to increase the size of small vessels in patients with juxta-anastomosis stenosis (JAS) requiring full-length dissection. The small-caliber segment that is adjacent to JAS is usually expanded using balloon angioplasty or surgically resected. After resection, if the cannulation site is sufficient, only the arterial anastomosis is moved proximally; otherwise, it is replaced with a prosthetic graft. Herein, we describe the cases of two 60- and 34-year-old men with left brachio-basilar and left radiocephalic fistulas, respectively. The first and second patients needed transposition and s...

Ruminant model for hemodialysis cannulation
CONCLUSIONS: The stability of AVF patency and flow underscores the viability and potential of the Caprine species animal model as a valuable research platform for exploring interventions aimed at improving vascular access survival in hemodialysis patients.PMID:38659087 | DOI:10.1177/11297298241247085 (Source: The Journal of Vascular Access)

Perioperative arterial catheterization: A prospective evaluation of ultrasound, infection, and patient-focused outcomes
CONCLUSIONS: Thrombosis was the most common abnormality and was usually asymptomatic. There were no infections, few post-operative symptoms, and minimal functional impairment following arterial catheterization.PMID:38659089 | DOI:10.1177/11297298241246300 (Source: The Journal of Vascular Access)
