Interhemispheric Approach for Intracranial Aneurysms / 대한뇌혈관학회지

ABSTRACT

The author describes the basic and standard operative method of interhemispheric(IH) approach for intracranial aneurysms especially aneurysm in anterior cerebral artery territory.Though most neurosurgeons prefer to pterional approach for anterior communicating artery aneurysm, some neurosurgeons select IH approach routinely for this aneurysm because of least brain retraction and excellent anatomical orientation with this approach. But IH approach should be chosen for distal anterior cerebral artery aneurysms and certain cases of anterior communicating artery aneurysms such as high positioned aneurysm or aneurysm with significant hematoma at frontal lobe. interhemispheric approach.
