Summary
Arteriovenous malformations (AVMs) are rare congenital vascular anomalies. Early diagnosis through thorough examination and advanced imaging is crucial for dental practitioners to prevent potentially fatal bleeding during procedures.
Area of Science:
- Vascular Surgery
- Oral and Maxillofacial Surgery
- Pediatric Dentistry
Background:
- Arteriovenous malformations (AVMs) are rare congenital vascular anomalies, comprising 1.5% of all vascular anomalies.
- Fifty percent of AVMs occur in the oral and maxillofacial region, often resulting from congenital vascular defects.
Observation:
- A case report details the accidental diagnosis of an asymptomatic high-flow AVM in a pediatric patient presenting for periapical abscess treatment.
- Despite no prior bleeding history, clinical examination and investigations confirmed the high-flow vascular malformation.
Findings:
- Few case reports exist for facial AVMs, highlighting diagnostic challenges and potential for fatal hemorrhage during dental procedures like extractions or surgical interventions.
- This case underscores the importance of recognizing AVMs, even when asymptomatic, in the head and neck region.
Implications:
- Dental practitioners must maintain high awareness of AVMs in the head and neck, as undiagnosed cases can lead to life-threatening bleeding during routine procedures.
- Comprehensive patient history, meticulous clinical examination, and advanced imaging are essential for accurate AVM diagnosis and prevention of severe complications.
