1 A ruptured cerebral aneurysm causes a stroke.

2 Objective To produce an animal model of cerebral aneurysm after a short period elastase application.

3 At present, computer-aided diagnosis for cerebral aneurysm technology is still at research stage, so there is no clinical application.

4 Methods A rat model of cerebral aneurysm was established. The dynamic changes of MMP-2, MMP-9 and TIMP-1 expression were examined in the process of aneurysm formation.

5 It is still to diagnose cerebral aneurysm according to observing angiography images by clinician, whose disadvantage is poor accuracy and objectivity.

6 Aim:To observe whether cerebral aneurysm could be induced in stroke-prone renovascular hypertensive rats.

7 Cerebral aneurysm and arteriovenous malformation are frequent disease of cerebral vessels.

8 To evaluate the endovascular embolizing therapy of ruptured cerebral aneurysm in early bleeding period.

9 Pathologic changes of cerebral aneurysm biopsies from 27 were studied by light microscope and electron microscope.

10 Two dimensional flat, airfoil, prolate spheroid and cerebral aneurysm were calculated as examples compared with experiment data.

11 Ruptured cerebral aneurysm is one of the important reasons for subarachnoid hemorrhage.

12 Conclusion The cerebral aneurysm is the most common cause for SAH, and the effective diagnostic method of SAH is cerebral angiography.

13 Conclusion The virtual three-dimensional cerebral aneurysm model that was established by the software method would be useful in assisting morphology study and guiding clinical work.

14 Conclusions This model has not only digital but also individual properties, and can be used to calculate the hemodynamic property in cerebral aneurysm and help to analyze its rupture mechanism.

15 Objective Cerebral ischemia is one of the main factors affect prognosis of cerebral aneurysm.

16 Firstly, this paper does research on basic knowledge such as cerebral aneurysm and DSA imaging principle and so on; analyzes the processes and methods of cerebral aneurysm diagnosis by clinicians.

17 Objective:To compare the effects of propofol on the patients undergoing cerebral aneurysm clipping with brain tumor removal.

18 Spontaneous subarachnoid hemorrhage (SAH) is a common presentation in an emergency department and most often results from a ruptured cerebral aneurysm.

19 Objective To establish the finite element model of 3D reconstruction for cerebral aneurysm to provide the basic analysis with hemodynamic mechanism in rupture of cerebral aneurysm.
