Dị dạng động tĩnh mạch vùng tai: Nhân 8 trường hợp điều trị tại Khoa Phẫu thuật tạo hình và Hàm mặt, Bệnh viện Việt Đức

Abstract

Objective: To evaluate the symptoms and results after treatment of auricular arteriovenous malformation; preliminarily recommend the indications. Subject and method: This retrospective review of 8 patients with auricular arteriovenous malformation was based on medical records, imaging studies, and photographs. Data were collected on natural history, progression, and outcome. Result: The median age at initial presentation was 27 years (range, 18 to 47 years), and by the Schobinger classification the were 4 patients in stage II and 4 patients in stage III. No patients had a Schobinger stage of I and IV. Mean follow-up time was 16 months (range, 1 to 33 months). All of 8 patients had embolization before resection. Two patients (25%) are improved, the others (75%) are controlled. Five patients (25%) had partial ear resection, two patients had total ear resection and one (12,5%) had needed  latissimus dorsi flap transfer. No one had ear reconstruction. Conclusion: The auricular arteriovenous malformation is typical. Treatment consists of surveillance, embolization, and surgery. The authors recommend periodic evaluation for stage I auricular arteriovenous malformation and intervention if there is an evolution to stage II, III. Preoperative embolization and partial or total resection effectively control auricular and para-auricular arteriovenous malformation. Embolization can be palliative in children or in patients who are not psychologically prepared for amputation.
