Symptomatic giant extracranial internal carotid artery (ICA) aneurysm is a rare and surgically intractable disease. Several authors have described successful treatments for extracranial ICA aneurysm. None, however, have described a perioperative evaluation of cerebral perfusion or a postoperative complication of cerebral hyperperfusion syndrome (CHS). We present a rare case of CHS after endovascular covered stent grafting for a giant extracranial ICA aneurysm. The CHS was successfully managed on the basis of hemodynamic monitoring. CHS can appear after endovascular reconstruction of an extracranial ICA aneurysm, and perioperative repeated evaluation of cerebral perfusion allows safe and effective management of CHS.
