Arteriovenous malformation with auricular hypertrophy
1Department of Otolaryngology, Teikyo University School of Medicine, Ichihara, Japan.
Summary
This case study details an arteriovenous malformation (AVM) affecting the auricle. Surgical ligation of the external carotid artery successfully treated the condition, followed by auricular plasty.
Area of Science:
- Vascular Surgery
- Dermatology
- Plastic Surgery
Background:
- Arteriovenous malformations (AVMs) are complex vascular anomalies.
- Auricular AVMs are rare, presenting unique diagnostic and therapeutic challenges.
- This case focuses on an AVM localized to the auricle, supplied by the external carotid artery.
Observation:
- A patient presented with severe hypertrophy of the left auricle due to an AVM.
- The malformation was extensive, involving the entire auricle.
- Initial treatment involved surgical ligation of the superficial temporal artery.
Findings:
- Recurrent pulsation after superficial temporal artery ligation indicated persistent AVM supply.
- A second surgery ligated the external carotid artery at an inframandibular site.
- This intervention successfully addressed the auricular AVM.
Implications:
- Effective management of auricular AVMs may require identifying and ligating the primary feeding vessel, the external carotid artery.
- Surgical intervention can resolve AVMs, enabling subsequent reconstructive procedures.
- This case highlights the importance of thorough vascular assessment in managing localized AVMs.
