“…Resection of the genu of the corpus callosum allowed us to gain length in the proximal portion of the A2 and to cut the corner of the genu by resecting a small, clinically insignificant portion of the corpus callosum. Such resection of the corpus callosum is of no clinical significance to the patient and generally has been used to obtain proximal control when exposing ruptured pericallosal artery aneurysms (4,10,11). This maneuver also shortened the total arterial occlusion time and period of operative ischemia, because only one anastomosis was performed.…”

OBJECTIVE AND IMPORTANCE: Subarachnoid hemorrhage caused by an isolated dissection of the anterior cerebral artery (ACA) is an extremely rare problem. The optimal treatment for patients with this clinical scenario varies and is controversial in the literature. We report a patient with a hemorrhage from a distal ACA dissecting aneurysm at presentation 2 years after an arteriovenous malformation resection, who was treated effectively with excision of the diseased segment and direct revascularization of the ACA. We report this as the first case of delayed hemorrhagic arterial dissection after arteriovenous malformation resection treated with early revascularization. We review this rare topic and present our perspective on the method of treatment of ACA dissection. CLINICAL PRESENTATION: A 32-year-old woman was transferred to the University of Texas Southwestern Medical Center and admitted with subarachnoid and intraventricular hemorrhage. Angiography revealed the source of the hemorrhage to be a dissecting aneurysm of the pericallosal artery. INTERVENTION:The patient underwent surgery on the third day after hemorrhage for excision of the dissecting aneurysm and in situ primary anastomosis of the pericallosal artery. Exposure and anastomosis of the pericallosal artery was facilitated by partial resection of the genu of the corpus callosum. CONCLUSION: On the basis of our experience and review of the literature regarding this topic, an optimal treatment for a dissecting aneurysm with hemorrhage involving the pericallosal portion of the ACA at presentation is excision of the diseased segment followed by revascularization. This treatment should prevent rehemorrhage from the aneurysm and avoid iatrogenic ischemic complications to the ACA territory that would be likely with trapping of the aneurysm without revascularization.
