1 The middle cerebral artery, anterior cerebral artery and posterior cerebral artery of 37 healthy volunteers were examined by duplex transcranial color Doppler.

2 The anterior cerebral artery complex has the most frequent incidence of intracranial aneurysms.

3 MethodsThe clinical data of 21 patients with A2 anterior cerebral artery aneurysms, who underwent microsurgery through longitudinal fissure approach, were analyzed retrospectively.

4 Conclusion:The cortical branches occlusion of the anterior cerebral artery may cause the symptoms of contralateral hemiplegia, mutism or apathy.

5 Conclusions Microsurgery through longitudinal fissure approach for A2 anterior cerebral artery aneurysms can get good results.

6 Objective To explore the value and safety of neuronavigation used in the surgery for anterior cerebral artery aneurysms.

7 ObjectiveTo analyse and explore microsurgery skill and clinical effects of Surgical case study in A2 anterior cerebral artery aneurysms with longitudinal fissure approach.

8 The clinical, radiological and surgical findings of a ruptured aneurysm of pericallosal artery were analyzed. The variable CT patterns of ruptured aneurysms of anterior cerebral artery were discussed.

9 Methods:The clinical conditions and CT scan findings in 3 patients with the infarction in the territory of cortical branches of anterior cerebral artery were reviewed and analyzed.

10 The PC point was an important surgical landmark in planning the surgical strategy for treating infracallosal distal anterior cerebral artery aneurysms.

11 Methods SAH was produced by passing a nylon thread up through the right internal carotid artery and piercing a hole in the right anterior cerebral artery.

12 Objective To explore the significance of the trans-longitudinal fissure keyhole approach for distal anterior cerebral artery aneurysms.

13 Methods Focal ischemic models of middle cerebral artery occlusion (MCAO) were established by inserting nylon monofilament through the right common carotid artery into the anterior cerebral artery.

14 To further understand the clinical features of the infarction in the territory of cortical branches of anterior cerebral artery.

15 The authors are interested mainly in the course of the pericallosal branch of the anterior cerebral artery.
