PS: Haven't changed; it's messy. I'll get back to it later. Thank you.
The little girl Xixi now exhibits left-sided limb paralysis, which indicates a blood vessel occlusion. A blood vessel occlusion means that if it persists beyond a certain time, the brain tissue supplied by this blood vessel will undergo infarction.
Emergency surgery aims to restore blood supply before the brain tissue infarcts, reversing the illness and averting lifelong disability. Thus, the left-sided limb paralysis would return to normal.
Once brain tissue infarction occurs, the condition is irreversible, resulting in permanent left-sided limb paralysis.
The core of surgery for Moyamoya disease is still the treatment of blood vessels, specifically intracranial vascular surgery, with vascular anastomosis being the most critical aspect.
