Abstract

The operative techniques routinely used in our clinics of intracranial aneurysms, especially microsurgical techiniques were described. Recent statistics showed 272 cases of intracranial aneurysms, in which 58 cases of anterior communicating aneurysm were submitted to direct intracranial operations during surgical treatment. We have analyzed the factors infuencing the mortality involved in aneurysm surgery in 58 cases of anterior communicating aneurysm. The incidence of aneurysm in this location was 42.7%, the median time from most recent hemorrhage to surgery was 7-14 days and the mortality rate was 7.5%. The aneurysms were also analyzed with regard to size, multiplicity, direction and origin. Approzimately 70% projected inferior and 30% superiorly. Based on this direction, we have used frontal, pterional or interhemispheric approaches. Microsurgical technique during aneurysm surgery was stressed. We believed that microsurgical radial aneurysmal neck clipping or ligation is the method of choice under the hypotensive anesthesia and proximal ligation of anterior communicating artery is also effective procedure in selective cases of anterior communicating arterial aneurysm.
