title: [Combined treatment of auricular vascular neoplasms].
abstract: Two cases of combined treatment of auricular vascular neoplasms (arteriovenous malformation and hemangioma) are presented. Their two-step management included endovascular microembolization of the posterior auricular artery with polyvinyl alcohol (PVA 300, 500 mcm) and surgical resection of the tumour. The results confirm the feasibility of combination of traditional and endovascular surgery for the treatment of this pathology. Preoperative endovascular microembilization not only arrests hemorrhage from angiodysplasia but also decreases its size and isolates it from healthy tissues. Embolization of the posterior auricular artery can be performed only after the comprehensive angiographic evaluation of the blood flow in angiodysplasia and the adjacent vessels using superselective catheterization and officinal emboli.
