Endovascular obliteration of hypervascular lesions of the head and neck has become clinically accepted, but it may cause stroke and peripheral cranial nerve palsy. By using a flow-controlled technique to deliver the materials and by knowing the vascular anatomy of the cranial nerves, these problems are less likely to occur. Occasionally, though, vascular anatomy is distorted by the lesion or is anomalous in its distribution. A provocative test of lidocaine injected into the appropriate artery seems to offer a functional test of whether the capillary bed will tolerate small-particle or liquid plastic occlusion. Twenty-six patients had various branches of their external carotid arteries challenged with lidocaine. Three developed transient palsies, and their treatments were modified. None of the 26 patients developed a complication of embolization.
头颈部高血运病变的血管内闭塞术已被临床所接受，但它可能导致中风和周围性颅神经麻痹。通过使用流量控制技术输送材料并了解颅神经的血管解剖结构，这些问题不太可能发生。不过，偶尔病变会使血管解剖结构变形或其分布异常。向适当动脉注射利多卡因的激发试验似乎可对毛细血管床是否能耐受小颗粒或液体栓塞剂提供功能测试。26例患者的颈外动脉各分支接受了利多卡因激发试验。3例出现短暂性麻痹，其治疗方案得以修改。26例患者均未发生栓塞并发症。
