In 1998 the arteriovenous fistula in occasion of absence of peripheric veins and necessities of periodic infusional therapy (a serious bronchial asthma) is imposed. A week ago there was a feeling of vibration of a forearm. About what it can speak?

Most likely about narrowing an anastomosis between arteries and a vein.
