Abstract: Objective To study the effect of minimally invasive decompression on the treatment of malignant middle cerebral artery infarction. Method There were 13 cases under minimally invasive decompression in the treatment of massive cerebral infarction from December 2012 to December 2016 in our department, 4 male cases, 9 female cases, and aged from 22 to 85 years old, of which 6 cases with patients older than 60 years. The telephone follow-up was conducted at 180th day after the attack, and the modified Rankin cale (mRS) was used to evaluate prognosis. mRS ≤ 2 scored favorable prognosis, mRS>2 scored unfavorable prognosis. Result 4 cases among 13 cases died from cerebral hernia and associated severe complications, and the death rate was 30.8%. 1 case died from massive hemorrhage of upper gastrointestinal tract gallstones. There were 5 cases of mRS ≤ 2, and 3 cases of mRS>2 among 8 survivor cases. There was no complication, such as intracranial infection, hemorrhage or subdural hematoma. Conclusion Minimally invasive decompression in the treatment of malignant middle cerebral artery infarction decreased significantly the death rate. This method was simple, fast, safe, and effective, without age limit and complication.
