Dysplastic vessels after surgery for brain arteriovenous malformations.

abstract：BACKGROUND AND PURPOSE:Persons with early stages of chronic kidney disease, defined by a decreased glomerular filtration rate (GFR), have an increased risk of cardiovascular disease. It is unclear whether decreased GFR is a risk factor for stroke. We assessed the association between GFR and stroke in a prospective popu...
