Successful endovascular treatment of extra-intracranial arteriovenous malformation using a combination of liquid non-adhesive embolic agents

Congenital malformations of blood vessels, including arteriovenous malformations (AVMs), are a less common pathology, which remains one of the most diagnostically and therapeutically complex diseases for treatment. Patients with vascular abnormalities often receive an erroneous diagnosis and inadequate treatment. Depending on the abnormality, such improper treatment can lead to potential long-term functional and cosmetic consequences. Existing treatment options include surgical resection, endovascular embolization, and a combination of these methods. To date, there is no pharmacotherapy available that allows you to radically treat this pathology. Despite recent advances, AVMs are rarely cured and may require multi-stage therapy throughout life. The article presents a clinical case of successful endovascular treatment of extra-intracranial arteriovenous malformation of the frontoparietal region in a young girl with a more pronounced extracranial component of AVM on the front and frontoparietal region with cosmetic and functionally significant defect. We performed double-stage embolization of AVMs with a combination of non-adhesive liquid embolic agents with high and low viscosity. We got good angiographic, clinical and cosmetic treatment results. © 2020 The Authors
