本文介绍了本室建立的围堤式颅窗软脑膜微循环观察方法。大鼠暴露颅骨，顶骨钻孔后，固定一根４号头皮针于骨孔边缘，将牙托粉、牙托水调匀后于骨孔周围围一个环形堤，根据需要硬脑膜可以保持完整或剥去。经头皮针持续向颅窗内输恒温人工脑脊液（ａＣＳＦ），并维持颅窗内ａＣＳＦ的ｐＨ值和Ｐｃｏ２于正常水平。颅窗内数毫米厚的ａＣＳＦ将外界隔开，使脑组织和软脑膜处于较好的生理环境。围堤式颅窗简便易行，并可达到与密闭颅窗相似的效果。
This paper introduces the method of observing microcirculation of pouch type plinth cranial window. After exposing the skull to the rat, the bones of the parietal bone were drilled. A scalp of No. 4 was fixed on the edge of the bone hole. After the trapezoid powder and the denture were thoroughly mixed, a circular dike around the bone hole was formed. The dura mater could be kept intact or peeled go with. The scalp acupuncture continued to cryogenic intracranial and intracranial artificial cerebrospinal fluid (aCSF), and maintain aCSF cranial window of the pH and Pco2 at normal levels. A few millimeters thick cranial window aCSF will be separated from the outside world, so that brain tissue and pia mater in a better physiological environment. Wai-style cranial window is simple and can achieve the effect similar to closed cranial window.
