Voluminous arteriovenous malformation of a child's forearm treated by sequential embolizations: case report.
An arteriovenous malformation (AVM) is a congenital lesion with high vascular flow resulting from direct connections between arteries and veins. Its treatment is often complex, and most authors recommend a multidisciplinary approach combining surgical and endovascular treatments. We report the case of a 6-month-old boy with a voluminous AVM of the left forearm inducing osteolysis of the radius, with bowing of its diaphysis and subsequent radial head dislocation. Surgical excision of the AVM was not possible, but 2 sequential coil embolizations achieved control of the lesion. After 3.5 years, the AVM was undetectable, and notable improvement was noted both in symptoms and radiographic findings. This case underlines how an AVM can have noteworthy influence on surrounding tissues and shows that embolization alone can achieve a satisfying midterm outcome even when surgery is not possible.
