Abstract：
UNASSIGNED: Scalp arteriovenous malformations (AVM) are rare vascular malformations reported only in small case series. Scalp AVMs usually present with symptoms, including headache, tinnitus, epilepsy, cerebral ischemia, and necrosis of the scalp, which can cause functional, cosmetic, and psychological problems. There are many difficulties in the treatment of scalp AVM because of its complex characteristics of vascular anatomy, non-uniform structure, and intracranial-extracranial anastomosis.
UNASSIGNED: To illustrate the endovascular treatment of scalp AVM via direct percutaneous puncture while traditional arterial and venous approaches were not available. In this report, access was obtained through a direct puncture of the enlarged frontal vein. Onyx-18 was injected through a microcatheter to occlude draining veins, fistulous connection, and the feeders. An 18-gauge indwelling needle was inserted into draining veins directly. Postembolization angiography demonstrated complete sAVM occlusion immediately and no non-targeted embolization. At a 1-year follow-up, no procedure-related complications and evidence of recurrence were observed.
UNASSIGNED: The technique of endovascular embolization via direct percutaneous puncture approach is safe, rapid, and effective for specific sAVM. Treatment options should be made in terms of size, vascular anatomical characteristics of the lesions, patient\'s preference, cosmetic factors, and available expertise.

摘要：
■头皮动静脉畸形（AVM）是仅在小病例系列中报道的罕见血管畸形。头皮AVM通常会出现症状，包括头痛,耳鸣,癫痫,脑缺血,头皮坏死，这可能会导致功能性，化妆品,和心理问题。头皮AVM由于其血管解剖复杂的特点,在治疗上存在许多困难,非均匀结构,颅内外吻合.
■为了说明通过直接经皮穿刺对头皮AVM进行血管内治疗，而传统的动脉和静脉方法不可用。在这份报告中,通过直接穿刺扩大的额静脉获得进入。Onyx-18通过微导管注射以阻塞引流静脉，拳头连接，和喂食器。将18号留置针直接插入引流静脉。栓塞后血管造影显示sAVM立即完全闭塞，没有非靶向栓塞。在1年的随访中，未观察到手术相关并发症和复发证据.
■直接经皮穿刺血管内栓塞技术是安全的，快速,对特定的sAVM有效。治疗方案应该根据尺寸来选择，病变的血管解剖特征，患者的偏好，美容因素，和可用的专业知识。
