Middle cerebral artery aneurysm ( MCAA ), as a common intracranial aneurysm, grows mostly at the bifurcations and lateral walls of artery blood vessels. Studies show that the complete embolization rate and good prognosis of wide-necked MCAA treated with craniotomy clipping and endovascular intervention had no significant difference, but the length of hospital stays and complications of the interventional therapy were significantly lower than those of craniotomy clipping. Therefore, the intravascular interventional therapy is safer and can be preferentially used.
