Hemangioblastoma is a rare tumor of vascular origin, most commonly located in the posterior fossa, which presents with severe symptoms and usually very hard to resect without remarkable operative blood loss. Pre-operative embolization may decrease the amount of intra-operative bleeding, but the endovascular treatment of such tumor may be very challenging due to the high risk of infarction of the surrounding tissues. Direct puncture embolization has been developed to overcome many of the limitations of endovascular techniques for many hypervascular lesions, also hemangioblastomas. We present in this Technical Video (video 1) a direct puncture embolization with balloon-protection of a hemangioblastoma of the medulla oblongata using Onyx 18 (Medtronic, inc.) as sole liquid embolic agent.
血管母细胞瘤是一种罕见的血管来源肿瘤，最常见于后颅窝，其症状严重，通常在没有明显手术失血的情况下很难切除。术前栓塞可以减少术中出血，但由于周围组织梗死的风险很高，这种肿瘤的血管内治疗可能非常具有挑战性。直接穿刺栓塞已经发展成为克服许多高血运病变，包括血管母细胞瘤的血管内技术的局限性。我们在这个技术视频（视频 1）中展示了使用 Onyx 18（美敦力公司）作为唯一的液体栓塞剂，对延髓的血管母细胞瘤进行直接穿刺栓塞并用球囊保护。
