Familial Arteriovenous Malformation in Extremity: A Case Report

Arteriovenous malformation (AVM) is a genetic vascular anomaly that can significantly affect daily activities. Its occurrence varies by race and gender, being more common in women. This report examines AVM in two siblings, aged 12 and 14. Clinical, radiological, and pathological evaluations revealed differing tumor sizes, expansions, and causes of vascular enlargement. Consequently, the siblings received different treatments: one underwent embolization, while the other had a wide excision. Both approaches resulted in favorable outcomes. AVM is a vascular neoplasm that may present at birth or be discovered later, often during routine check-ups or after trauma. The familial nature of AVM in this case emphasizes the variability in presentation and treatment response. Established diagnostic and therapeutic guidelines may not always be applicable, necessitating individualized treatment plans. This case highlights the importance of tailored treatment approaches for familial AVM, demonstrating successful outcomes with both embolization and wide excision.
