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.

✓ This study reviews aneurysms of the proximal segment (A1) of the anterior cerebral artery in 38 patients (23 men and 15 women) and their surgical, angiographic, and clinical management. Thirty-seven aneurysms were saccular and one was fusiform. The incidence of A1 aneurysms among a total of 4295 aneurysm cases treated was 0.88%. Multiple aneurysms occurred in 17 patients (44.7%) of the 38 cases; in 10 (58.8%), there was bleeding from the A1 aneurysm. The aneurysms were classified into five categories according to the mode of origin of the aneurysm in relation to the A1 segment: in 21 cases, aneurysms originated from the junction of the A1 segment and a perforating artery; in eight, from the A1 segment directly; in six, from the proximal end of the A1 fenestration; and in two, from the junction of the A1 segment and the cortical branch. One patient had a fusiform aneurysm. Computerized tomography (CT) of these aneurysms revealed bleeding extending to the septum pellucidum similar to that of anterior communicating artery aneurysms. When performing radical surgery it is very important to recognize the characteristics of A1 aneurysms, including multiplicity, a high incidence of vascular anomalies (especially A1 fenestration), and their similarity to anterior communicating artery aneurysms on CT.

✓ A case of a giant anterior cerebral artery fusiform aneurysm is presented. The lesion was treated by primary excision of the involved segment with an end-to-end anastomosis of the proximal-distal segments of the anterior cerebral artery. It is believed that this technique has not been reported previously for lesions involving major intracranial arteries.

We report 2 cases of parent artery occlusion (PAO) for anterior cerebral artery (ACA) fusiform aneurysm embolization after superselective provocative testing was performed to confirm distal territory viability. The first case involves a patient in the second decade of life who presented with subarachnoid hemorrhage and underwent PAO after a balloon test occlusion in the distal ACA revealed no neurophysiology changes. The second case involves another patient in the forth decade of life who presented with an enlarging pseudoaneurysm and underwent PAO after a sodium amobarbital infusion in the distal ACA revealed no clinical change. Both patients tolerated PAO without clinical compromise. PAO after provocative testing may be a safe and effective strategy in the management of fusiform aneurysm treatment. Key Messages: Provocative testing with superselective balloon test occlusion and sodium amobarbital infusion are both viable options for clinical and physiological interrogation of brain tissue prior to parent vessel occlusion. Neurophysiological monitoring may be a useful surrogate for clinical examination after provocative testing, particularly if patients were treated under general anesthesia.
