A Tangled Web Arteriovenous Malformation Weaves

When your arteries and veins abnormally tangle, a web of deceit begins brewing forming AVM nidus.

Shout out to Mayfield clinic for helping break down the complexities of arteriovenous malformation (AVM).

This is what I was able to understand…

It’s understood that blood flows from the heart, through your larger arteries to the body’s cells.

Arteries: Carry oxygen-rich blood away from the heart to the body’s cells

The arteries branch until they form into a capillary.

Capillary: Any of the branching blood vessels that form a network between the arterioles and venues.

A bed of capillaries is formed, and the powerful exchange of oxygen and nutrients takes place.

That blood travels away from the capillary bed back to the heart through your veins.

Veins: Return oxygen-depleted blood to the lungs and heart.

The AVM tangled web of blood vessels and arteries connect directly LEAVING OUT the critical capillary bed. So you get arteries that are in a feeding frenzy and enlarged veins form.

An AVM can rupture. The bleeding also can be held responsible for a possible stroke.

The risk of AVM bleeding is 2 to 3% per year. Death from the first hemorrhage is between 10 to 30%. Once a hemorrhage has occurred, the AVM is 9 times more likely to bleed again during the first year.

I found a GREAT VIDEO of Dr. John Hudson and Dr. Ted Larson giving a brief overview and discussion on AVM’s and treatment modality.

It’s 8 MINUTES OF SOLID AVM EDUCATION. Definitely worth a listen.

(Heads up: volume is low!)

Much love,
