Abstract
A 78-year-old male patient was referred for diagnostic work-up 31 months after an ischemic stroke affecting the left parietal lobe. An incidental giant, partly thrombosed aneurysm located on the left A1 segment of the anterior cerebral artery (ACA) causing compression of the third ventricle and a noncommunicating hydrocephalus was diagnosed. A stenosis of the left A1 segment proximal to the aneurysm neck was considered to be either an atherosclerotic lesion or due to a previous dissection. An external ventricular drain was placed prior to endovascular parent vessel reconstruction using a p48 (phenox) flow diverter (FD). MRI/MRA and DSA follow-up showed the complete occlusion of the aneurysm and a remodeling of the parent artery. The clinical condition of the patient was the same as before the intervention, and no new neurological deficit had occurred. The treatment of A1 aneurysms with FD stents is the main topic of this chapter.
