Abstract
BackgroundThe Middle cerebral artery (MCA) aneurysm is a common type of craniocerebral aneurysm that is prone to rupture and high mortality. The classic surgical approaches are the Pterional approach and the Lateral Supraorbital (LSO) approach, but there are shortcomings.MethodsThis study retrospectively analyzed clinical and imaging data from 181 patients with MCA aneurysm clipping in the Department of Neurosurgery, First Affiliated Hospital of Soochow University between 2011 and 2017. Statistical analysis using parametric and nonparametric tests showed that P values below 0.05 were considered statistically significant.ResultsThe preoperative GCS score (P = 0.003), Hunt-Hess scale (P < 0.001) and the operating habits of the surgeon (P < 0.001) affected the surgeon to choose a surgical approach. The choice of two surgical methods on the operation time (P < 0.001), skin incision (P < 0.001), complications (P = 0.026), tracheotomy (P = 0.014), prognosis (P = 0.002) were significantly different. Different surgical approaches (P = 0.002), Hunt-Hess scale (P < 0.001), GCS scale (P < 0.001), GCS sorse (P < 0.001), skin incision (P = 0.031) and complications (P < 0.001) are closely related to the prognosis of patients.ConclusionsModified LSO approach provides another surgical approach for MCA aneurysm clipping, while avoiding the drawbacks of the LSO approach in the clipping of MCA distal aneurysm.

Middle Cerebral Artery (MCA) aneurysm is a common type of craniocerebral aneurysm, the incidence of which accounted for 20% of all aneurysms
The classic Lateral Supraorbital (LSO) approach used in other anterior circulation aneurysm or basilar artery aneurysm eliminated some cases of MCA aneurysms involving interventional therapy or abandonment of surgery
Summary
The Middle cerebral artery (MCA) aneurysm is a common type of craniocerebral aneurysm that is prone to rupture and high mortality. Middle Cerebral Artery (MCA) aneurysm is a common type of craniocerebral aneurysm, the incidence of which accounted for 20% of all aneurysms. Many cerebral aneurysms and saddle tumors were treated with the Lateral Supraorbital (LSO) approach when J. The Pterional keyhole and Lateral supraorbital keyhole and other surgical approaches are applicable to clinical [4,5,6]. These surgical methods will undoubtedly bring more possibilities for the director medical treatment of patients, but various surgical methods have their own advantages and disadvantages. The Pterional approach creates larger skin incisions in patients, at the same time, the
