For clipping by the pterional approach of the anterior communicating artery aneurysm, we decided the appropriate approach side based on CT angiography in preoperation, and a right-handed operator clipped 20 consecutive cases. The left side and the side on which both of A2 were closed were the most frequent approaches. All cases were clipped completely, but, as surgical complications, two cases of olfactory dysfunction and six cases of cerebral infarction of the caudate head were produced.
In clipping by the pterional approach of the anterior communicating artery aneurysm, adequate preoperative examination based on the form of aneurysm and adequate intraoperative care for the perforating arteries are important.
