Minimally Invasive Soft Channel Brain Haemorrhage Evacuation for Acute Basal Ganglia Haemorrhage--Small Hemorrhage Evacuation (MIRACLE-S)

During the study treatment and follow-up periods, patients are to receive usual standard of care according to published guidelines for acute stroke care. It is anticipated that background care may include the use of other treatments including drugs and interventions.

This technique is based on the study of hematoma anatomy, cerebral vascular anatomy, and neural fiber structure anatomy in basal ganglia hemorrhage to determine the optimal surgical (catheter insertion) path. By applying stereogeometric principles, it allows for simple yet precise localization. Through surgical steps including puncture, aspiration, liquefaction (intermittent infusion of urokinase or alteplase), and external drainage, the hematoma can be completely removed in stages over a short period. This ensures that hematoma clearance and decompression of the brain occur simultaneously, achieving a minimally invasive intracerebral hemorrhage evacuation technique with a gradual reduction in intracranial pressure.
