Summary
Arteriovenous malformations (AVM) are rare facial vascular anomalies. This case highlights a lip AVM, emphasizing the need for early detection and intervention to prevent serious bleeding and airway obstruction.
Area of Science:
- Vascular Surgery
- Dermatology
- Plastic Surgery
Background:
- Arteriovenous malformations (AVM) are abnormal connections between arteries and veins, lacking capillaries.
- While common in the brain, AVMs are exceptionally rare in facial locations, particularly the lips.
- Lip AVMs are susceptible to trauma, potentially causing severe hemorrhage due to their exposed anatomical position.
