Plain English summary of protocol
Background and study aims
Normally, the kidneys filter the blood, removing harmful waste products and excess fluid and turning these into urine to be passed out of the body. Dialysis is a procedure to remove waste products and excess fluid from the blood when the kidneys stop working properly. Dialysis often involves diverting blood out of the body to a machine that acts similarly to a kidney to filter the blood and then is returned to the body. In order to remove and return the blood from the body on multiple occasions for dialysis, a point of access will be created surgically. There are a number of methods that may be used including an arteriovenous graft which is a looped tube that connects an artery to a vein. This tube may be made of plastic such as polytetrafluoroethylene (PTFE) or biological material such as bovine carotid artery.
This study will compare whether the grafted tube remains open to the flow of blood 12 months after surgery in patients who received a bovine carotid artery graft.
Who can participate?
Adult patients who received surgical placement of a bovine carotid artery graft between 2017-2018
What does the study involve?
This study involves a retrospective review of all patients undergoing surgical placement of a bovine carotid artery graft for dialysis access between 2017-2018 at Louisiana State University Health Sciences Center.
Data on the extent to which the graft remains open to allow blood flow (patency) will be collected from patient records for the whole cohort and results determined based on gender, BMI, and indication for use. The outcomes of bovine carotid artery grafts will be compared to polytetrafluoroethylene (PTFE) grafts performed at the same institution between 2013 and 2016.
What are the possible benefits and risks of participating?
There is no human risk involved as this is retrospective study.
Where is the study run from?
Louisiana State University Health Sciences Center (USA)
When is the study starting and how long is it expected to run for?
From September 2019 to September 2021
