Management of Extra-cranial Arteriovenous Malformations of the Scalp: A case report

Arteriovenous malformations (AVMs) are congenital fast-flow vascular malformations characterized by abnormally tangled arteries and veins connected by abnormal shunts without intervening capillaries. The growth of AVMs is usually initiated by trauma and hormonal changes in puberty. Compared to the intracranial AVMs, extracranial AVMs are rare. The treatment of extracranial AVMs, though poses a challenge to the surgeon, is debilitating to the patients. We report a case of extracranial arteriovenous malformation of the head in a young man who noticed it from childhood. He was clinically and radiologically evaluated using CT angiography and had two-stage surgical interventions.
