OBJECTIVE
To show that migraine pain is not related to dilatation of the dural meningeal arteries.
BACKGROUND
The origin of the pain in migraine has not yet been adequately explained and remains the subject of vigorous debate. Current theories implicate changes in the trigeminovascular system, which is defined as comprising the large intracranial vessels, and in particular, the dural meningeal vessels, the dura mater, and their neural connections.
METHODS
The anatomical relationships of the dural meningeal arteries to the dura mater and the inner surface of the calvarium are described.
RESULTS
The dural meningeal arteries lie in grooves in the inner table of the calvarium, are encased in the unyielding fibrous dura mater, and are consequently unable to dilate.
CONCLUSION
The pain of migraine is not related to dilatation of the dural meningeal arteries.
目的
表明偏头痛疼痛与硬脑膜动脉扩张无关。
背景
偏头痛的疼痛起源尚未得到充分解释，仍然是激烈争论的主题。目前的理论涉及三叉血管系统的变化，该系统被定义为包括颅内大血管，特别是硬脑膜血管、硬脑膜及其神经连接。
方法
描述了硬脑膜动脉与硬脑膜和颅骨内表面的解剖关系。
结果
硬脑膜动脉位于颅骨内板的凹槽内，被坚韧的纤维硬脑膜包裹，因此无法扩张。
结论
偏头痛的疼痛与硬脑膜动脉扩张无关。
