It is important that forceps for aneurysm clips should be used unclasping when neurosurgeons are trying to approach and to clip aneurysm neck. It is difficult to insert clip beside aneurysm neck clipping forceps since the tip of clip is fixed and surgeons can not control the width of the tip of clip.<BR>We emphasize that necessity of some techniques of clipping by the left hand even the right-handed surgeons. In some cases such as aneurysms of the left ophthalmic artery, internal carotid artery, and some basilar artery and anterior communicating artery by the left pterional approach, it is more convenient to use for clipping by the left hand than using the right hand. In such cases we can use the right hand to separate and to move surrounding cranial nerves and perforating arteries. We should train to use both hands for clipping aneurysm necks skillfully.
