Doomed peripheral intravenous catheters: Bad Outcomes are similar for emergency department and inpatient placed catheters: A retrospective medical record review.
Authors: Kache S, Patel S, Chen NW, Qu L, Bahl A Abstract INTRODUCTION: The survivorship of peripheral intravenous catheters (PIVCs) placed in hospitalized patients is shockingly poor and leads to frequent reinsertions. We aimed to evaluate differences in failure rates and IV insertion practices for PIVCs that are placed in the emergency department (ED) compared to those placed in the inpatient (IP) setting. METHODS: We conducted a retrospective electronic medical record review of PIVC survival at a single-site suburban, academic tertiary care referral center with 130,000 annual ED visits and 1100 inpatient bed...

The past and the future of vascular access surgery: Creation of percutaneous arteriovenous fistula using Ellipsys vascular access system in a patient with previous ipsilateral Scribner-shunt.
CONCLUSIONS: This is the first report of the creation of pAVF in a patient with previous "traumatic" ipsilateral placement of a Scribner-shunt. It allows the creation of a small anastomosis in very short time, which can be successfully used for hemodialysis treatment on the same day, if necessary, and reduces the expected risk of high-flow AVF with associated peripheral steal and cardiac outcomes (especially in a patient with cardiomyopathy such this one).

Tapered and non-tapered prosthetic grafts in upper extremity dialysis access: A systematic review and meta-analysis.
CONCLUSIONS: The risk of ischemic steal syndrome and patency rate are comparable for upper extremity tapered and non-tapered AVGs. This meta-analysis does not support the routine use of tapered graft over non-tapered graft to prevent ischemic steal syndrome in upper extremity dialysis access. However, due to small number of studies and sample sizes as well as limited stratification of outcomes based on risk factors, future studies should take such limitations into account while designing more robust protocols to elucidate this issue.

Comparing Outcomes of Upper Extremity Brachiobasilic Arteriovenous Fistulas and Arteriovenous Grafts: A Systematic Review and Meta-Analysis.
The objective of this systematic review and meta-analysis was to compare the outcomes for upper extremity transposed brachiobasilic AVFs (BBAVFs) and prosthetic arteriovenous grafts (AVGs). METHODS: A systematic review was performed to identify all English publications and abstracts comparing the patency outcomes of upper extremity BBAVFs and AVGs (January 1st, 1994 to April 1st, 2020). The outcomes assessed were 1-year and 2-year primary and secondary patency rates.

To ligate or not to ligate hemodialysis arteriovenous fistulas in kidney transplant patients.
Authors: Abreo K, Sachdeva B, Abreo AP Abstract There is significant disagreement about maintenance or ligation of arteriovenous fistulas (AVFs) in kidney transplant patients (KTPs). Potential harms from maintaining AVFs are their impact on cardiac function, cosmetic concerns and complications such as bleeding and rupture. High flow AVFs can place a strain on the heart and cause or exacerbate pre-existing cardiac dysfunction. There is an improvement in cardiac function after kidney transplantation independent of vascular access status. Studies comparing cardiac parameters in patients with and without AVFs after ren...

Determinants of venous catheter hemodialysis onset and subsequent switch to arteriovenous fistula: An epidemiological study in Lazio region.
CONCLUSION: The observed high rate of AVF at the start of hemodialysis and of the switch from CVC to AVF in the first year, although declining since 2008, is a positive outcome. However, over one-third of patients maintain the CVC as vascular access for the first year because of unmodifiable factors, such as gender, age, comorbidity. The present study suggests that logistics/management and assistance/welfare problems may contribute to the delay or lack of AVF placement in incident hemodialysis patients or within the first year of dialysis.

CONCLUSIONS: Both strategies were effective in controlling bacterial colonization. Glue was effective in reducing local bleeding, and it was more cost-effective than sponge dressing. During the first week, when local bleeding and bacterial colonization must be prevented, glue might be more appropriate than chlorhexidine-releasing dressing; after the first week chlorhexidine-releasing dressing might be preferable, considering that the safety of glue application on the skin for prolonged periods is still questionable.
