Hi every one, just a quick question, what is the difference between an AVM and an AVF?

Thanks, jg

An avm (arteriovenous malformation) has multiple abnormal connections between arteries and veins and looks like a tangled ball of spaghetti. An avf (arteriovenous fistula) may have many veins involved, but only a single abnormal arterial connection. Elsewhere, you asked about a DAVF. The D is for dural. The dura mater is the outerermost layer covering the brain.

Different doctors have used the term AVM and AVF for mine, so I’m not sure it is 100% clear cut.
