METHODS Data from 86 cases with intracranial CH from the Department of Neurosurgery of Tianjin Huanhu Hospital,Tianjin, China,during a period from 2000 to 2007,were retrospectively analyzed,and pertinent literature cited. RESULTS Epilepsy,headache,dizziness,sensory disability and limb-kinetic apraxia were the most commonly seen clinical manifestations of the intracranial CH cases.MRI was one of the preferred ways to diagnose CH.All 86 patients were treated with microsurgery,among which neuronavigator-guided surgery was conducted in 16,a second surgical procedure was performed in 3 due to a postoperative intracranial hematoma,and death occurred in 1.All the other 85 patients had a good prognosis. CONCLUSION MRI was the most sensitive diagnostic means for intracranial CH.Microsurgery was the main method to treat intracranial CH.展开更多

Thanks to the focused ion beam (FIB) tomography and the follow-up image processing, two 3D subsurface cracks and a cluster of inner cracks were picked out and discussed in this research. It was found that the subsurface crack (its length is about 15 part, width about 1-5 prn, and opening about 1 ~tm) was much larger than the inner crack (its length and width are about 1-5 pro, opening is from 200 nm to 1 pan), which arose from the sample preparation process. Besides, it was revealed that most of the inner cracks were in the form of clusters.展开更多
