A case of non-traumatic dissecting aneurysm of the A1 anterior cerebral artery and recent treatment trends

Abstract

We report a case of a non-traumatic dissecting aneurysm of the A1 anterior cerebral artery (ACA) with a subarachnoid hemorrhage. A 51-year-old man lost consciousness with acute onset and was sent to our hospital. CT, MRI/MRA, and cerebral angiography showed a left A1 ACA dissecting aneurysm. Trapping of the aneurysm was performed using a left front-temporal craniotomy, and the patient made a good recovery. We consider recent treatment for A1 ACA dissecting aneurysms with bleeding based on the literature cited, and the trapping of aneurysms may take priority over other methods.
