A series of 4 patients with aneurysm of distal anterior cerebral artery(DACA), operated with microtechniques, is reviewed. Because the incidence of aneurysms in this location was only 2 to 4% of that of total aneurysm, little expericences on surgical management of this aneurysm have been reported. An aneurysm in this location is difficult to approach surgically because of their multiplicity, characteristically broad and sclerotic base, with small subarachnoid space in the interhemispheric fissure. We surgically treated DACA aneurysms of 4 cases through the interhemispheric approach via the unilateral frontal paramedian craniotomy on the nondominant side.
