ABSTRACT: Arteriovenous malformation (AVM) are
vascular anomalies that arise due to abnormal connection with shunting of blood
from arteries to veins without an intervening capillary network. They are
mostly found intracranially but extracranially, the scalp AVM cases are also
well reported. However, arteriovenous malformation (AVM) of the scalp is a
rare lesion whose natural history is not clearly understood. The clinical
manifestation of AVM includes asymptomatic state, local discomfort, headaches
and occasional scalp necrosis leading to massive haemorrhage. CT or MR
angiography remains the cornerstone for investigation. The options of
treatment include complete surgical excision, embolization or a combination of
the two modalities. We present the successful management of a young man who
presented with a torrential bleeding from a ruptured scalp arteriovenous
malformation and had to undergo emergency complete excision followed with a
rotational flap for the scalp reconstruction.
