medical monday | the muscle of AVF

I was discussing with my colleague that after having the diabetes, hypertension and stroke combo (not me), the worse would be to be down with renal failure, especially end-stage.

She mentioned not only the long term repeated financially-draining dialysis, it is difficult to look for a good surgeon to make a good arteriovenous fistula.

I couldn't have agreed more. With so much of AVFs failing and creation of the new one, probably will make the whole arm looks 'muscular'.

Do you know?

Compression of AVF can cause bradycardia.
It is called the Nicoladoni sign.

A slowing of the heart rate (bradycardia) in response to (manual) compression of an arteriovenous fistula

A circulatory phenomenon observed in angioma racemosum of the extremities.Compression of an arteriovenous fistula causes bradycardia…if there is a significant circulation through the fistula.The phenomenon was first described by Nicoladoni in 1875, then by Israel in 1877 and Branham in 1890, and subsequently rediscovered by Wigdorowitsch in 1915.
