Patients with kidney disease may delay AVF creation
Many patients start hemodialysis with temporary vascular access despite regular kidney care and pre-dialysis education. Delay is often related to patient choice but research on patients' perspectives is limited. In this study, researchers surveyed pre-dialysis patients and their family members about their perceptions of chronic kidney disease (CKD) and their intentions to undergo access creation. They also report on a new survey instrument to measure attitudes towards hemodialysis preparation. (2020-12-03)

Without intervention, a 70% reduction in strokes or death in patients with brain AVMs
For people with a brain arteriovenous malformation (AVM), a congenital vascular system defect, fate has a name: stroke. To avoid this risk, patients sometimes undergo interventions to remove the malformation. But is this very beneficial? Not necessarily. According to an international clinical trial, co-directed by researchers from the University of Montreal Hospital Research Centre (CRCHUM), interventional treatment--by neurosurgery, neuroradiology or radiation therapy--could be more dangerous than the disease itself. (2020-06-17)

Study ties stroke-related brain blood vessel abnormality to gut bacteria
In a nationwide study, NIH funded researchers found that the presence of abnormal bundles of brittle blood vessels in the brain or spinal cord, called cavernous angiomas (CA), are linked to the composition of a person's gut bacteria. Also known as cerebral cavernous malformations, these lesions which contain slow moving or stagnant blood, can often cause hemorrhagic strokes, seizures, or headaches. (2020-06-03)

Simulations characterize turbulence caused by common connection for dialysis
The complex interplay among the arteriovenous grafts, the vessels they connect, and the blood they transport has been difficult to simulate, but one new method provides a way. Researchers report simulations that reconstructed the fluid dynamics affected by the insertion of an AVG. They used a model that considered the ability of AVG tubes and blood vessels to deform and found much of the disrupted flow could be mitigated by this flexibility. (2019-09-27)

One-fifth of US surgeons still overusing riskier procedure to create kidney dialysis access
Long-term hemodialysis is a lifesaver for approximately half a million patients in the United States with kidney failure (also known as end-stage renal disease, or ESRD) who are either waiting on or unsuitable for a kidney transplant. But before the external machinery can take over the function of the kidneys -- filtering and cleansing wastes from the blood -- a minor surgical procedure is needed to create a stable, functional and reusable access to the circulatory system, usually through blood vessels in the arm.
