从“初病气结在经,久病血伤入络”探讨偏头痛的病因病机

Discussing the Etiology and Pathogenesis of Migraine from the Perspective of"Stagnation of Qi Activity in the Meridians in the Initial Disease and Blood Injuries into the Collaterals in the Prolonged Disease"

以叶天士“初病气结在经,久病血伤入络”理论为基础,探讨偏头痛病机由经入络、从气结到血伤的动态演变过程,初期气结为主,治疗时应注意辨经脉、邪气的不同,及时疏散肝经气结,防止壅塞脉道,预防入里传变;后期因实致虚,络脉血伤,见脉络空虚,顽痰死血混处,证属虚实夹杂,病多胶结难愈,治疗时应当搜风通络以治标,补虚荣脉以治本,祛邪而不伤正,扶正以助祛邪。
