    Author: Kimura T, Nishimura K, Fukaya S, Morita A.
    Journal: Neurosurgery; 2010 May; 66(5):E1025-6. PubMed ID: 20404674.
    Abstract:
    OBJECTIVE: Fusiform aneurysm of the anterior cerebral artery is rare and difficult to treat because of perforators. We encountered a patient with subarachnoid hemorrhage due to rupture of a fusiform aneurysm of the anterior communicating artery complex, and treated this patient with cerebral revascularization. CASE PRESENTATION: A 39-year-old man presented with sudden severe headache resulting from subarachnoid hemorrhage. Digital subtraction angiography showed dilatation from the distal A1 segment to the proximal A2 segment of the left anterior cerebral artery. Despite intensive conservative treatment, repetitive angiography showed aneurysmal growth from this dilated portion. INTERVENTION: Proximal clipping and clip-on wrapping on the A2 segment was successfully performed with a A3-A3 bypass. He was discharged without neurological deficit. CONCLUSION: Cerebral revascularization technique is necessary to achieved appropriate obliteration without ischemic complications.
