Successful endovascular treatment of extracranial arteriovenous malformation of a head: a case report

. Arteriovenous malformations (AVM) of the head represent the rare lesions that have a congenital, traumatic or post-infectious nature. In the last decade, endovascular methods have become the most prevalent in the treatment of AVM. Staged embolization is performed to achieve maximum eect and minimize the complications. Case report . A 30-year-old female patient is presented with complaints of enlarged vessels in the frontal and parietal regions. CT-angiography scan and cerebral angiography showed extracranial AVM of the fronto-parietal regions with aerent vascular supply from the right and left supercial temporal and ophtalmic arteries with signicant expansion of the aerent arteries and the presence of varix dilatation of the draining veins. Two-stage endovascular embolization of AVM was performed. The rst stage was embolization of the aerent vessels from the left supercial temporal artery system with exclusion of 60–65% AVM volume. Three months later, the second stage was performed with embolization of the afferent vessels from the right supercial temporal artery system and the exclusion of 75–80% of the residual volume of AVM. The non-adhesive composition SQUIDR12 (Embou, Switzerland) and glue composition PHILR25% (Microvention, USA) were used. A good aesthetic eect was achieved. Postoperative complications were not observed. There was no recurrence during the observation within a year. Summary . The staging and the use of various liquid embolization agents in the treatment of AVM of the head allow to achieve a good aesthetic outcome and prevent complications associated with facial soft tissue necrosis.
