“…AVM was first reported by John Bell in 1815 using the term “aneurysm by anastomosis.” AVM is a pathological communication between arteries and veins via blood vessels such as a dilated capillary without interposition of the arteriole [ 10 ]. Collateral formation is consequently facilitated, and regional blood flow is increased at the peripheral level.…”

Background: Arteriovenous malformation (AVM) which is a high-blood-flow lesion with connections between arteries and veins without an intervening capillary bed, is difficult to manage. The ear is the second most common site of extracranial AVM. However, studies regarding the management of this condition remain lacking. The purpose of this study was to share managing experiences in our center and to investigate the treatment effect through a retrospective analysis of cases. Methods: Among 265 patients with AVM treated in our vascular anomalies center between January 2008 and January 2021, 10 patients with auricular AVM were included in the study to investigate the lesion distribution, clinical stage, and treatment methods by performing a retrospective evaluation. Results: Among 10 patients, five patients had AVMs distributed in the upper half of the ear, one patient in the lower half of the ear, and four patients in whole ear, respectively. Seven patients had Schobinger stage II, and three had stage III. One patient received surgical treatment only, four patients received sclerotherapy only, and five patients received both surgical treatment and sclerotherapy. The posttreatment status was checked as controlled in two patients, improved in seven patients, persistent in one patient. There were no worsening patients. Conclusion: Auricular AVM is a disease that is difficult to manage by one specific department, thus requiring a collaborative management effort from multidisciplinary team.

Patient: Female, 40-year-old Final Diagnosis: Arterio-venous malformation Symptoms: Neck swelling Medication: — Clinical Procedure: Coil embolization • surgical resection Specialty: Radiology Objective: Rare disease Background: Extracranial arteriovenous malformations (AVMs) of the parotid gland and auricle are rarely encountered. Management of these AVMs depends on the Schobinger stage and their flow characteristics. We present a rare case of an AVM involving the parotid and auricle concurrently. The clinical and imaging features of these high-flow vascular malformations and their treatment options are discussed and we provide a review of the literature. Case Report: A 40-year-old woman presented with a large 6.4×6.0×13.0 cm high-flow Schobinger stage II high-flow AVM of the parotid gland and auricle. Diagnostic imaging included magnetic resonance imaging (MRI) and conventional catheter angiogram, which defined the vascular anatomy and flow characteristics of the AVM. She was treated with preoperative endovascular embolization followed by surgical excision and free-tissue transfer reconstruction on the next day. The results were excellent, with no recurrence over 3.5 years of follow-up. Conclusions: This is the second case reported in the literature of high-flow AVM concurrently involving the parotid gland and auricle, treated with perioperative embolization followed by surgical excision and grafting. Management of AVMs requires a multidisciplinary team approach and understanding of the natural history of the lesion. Although total surgical resection is the criterion standard for these AVMs, endovascular embolization is an alternative treatment that can be used as an adjunct to surgery. Furthermore, perioperative embolization can decrease the vascularity of the lesion and effectively reduce blood loss during AVM surgery.
