When is an avm not really an avm?

Answer 1

An arteriovenous malformation (AVM) is not truly classified as such when it lacks the characteristic direct connections between arteries and veins without an intervening capillary network. Additionally, certain vascular anomalies that mimic AVMs, such as venous malformations or other vascular lesions, may be misidentified as AVMs but have different underlying pathophysiology. Accurate diagnosis often requires imaging studies and clinical evaluation to differentiate these conditions.
