Introduction
Aneurysm formation at the anastomosis site after extracranial–intracranial (EC–IC) bypass surgery for major arterial occlusion or stenosis due to atherosclerosis has only been reported a few times previously. However, no case describing the formation of a giant aneurysm after EC–IC bypass surgery has been reported to date. Additionally, this complication associated with moyamoya disease is extremely rare, and only one case has been reported so far.
Clinical report
We report a case of a 51-year-old woman having a rare complication of intracerebral hemorrhage due to rupture of a giant aneurysm that developed after superficial temporal artery–middle cerebral artery anastomosis for the treatment of moyamoya disease.
Conclusion
To the best of our knowledge, this is the first reported case of a giant aneurysm, also the largest so far occurring after EC–IC bypass surgery and the second reported case of a rupture of an aneurysm formed after bypass surgery for moyamoya disease.
