Inclusion Criteria:

1. Diagnosis of spontaneous basal ganglia hemorrhage by imaging (CT, CT angiography, etc.) with a volume between 15 to 30 mL and Glasgow Coma Scale score ≥ 9. 2. With dysfunction such as hematoma-related motor aphasia, sensory aphasia, hemiplegic limb muscle strength ≤ grade 3 or NIHSS score ≥ 15 points. 3. Diagnostic CT scan should be obtained within 24 hours after the onset of symptoms. 4. Hematoma stability shown by a CT scan at least 6 hours after the diagnostic CT (hematoma volume increase < 5 ml) 5. Surgery should be performed within 72 hours after onset. 6. Age between 18-70 years old. 7. Modified Rankin Scale score (mRS) ≤ 1 in past medical history. 8. Patients who are suitable and willing to be randomized to surgery group or conservative medical treatment.

Exclusion Criteria:

1. Hematoma involves other structures such as the thalamus and midbrain. 2. Mass effect or hydrocephalus due to intraventricular hemorrhage. 3. Imaging-based diagnosis of cerebrovascular abnormalities such as ruptured aneurysm, arteriovenous malformation (AVM) and moyamoya disease as well as hemorrhagic transformation of ischemic infarct and recent recurrence (within 1 year) of cerebral hemorrhage. 4. Manifestation of early stage cerebral herniation such as ipsilateral pupil changes and midline shift exceeding 1 cm. 5. Patients with unsteady hematoma or with progression to intracranial hypertension syndrome. 6. Patients with any irreversible coagulopathy or known coagulation disorders; platelet count <100,000; International normalized ratio (INR) > 1.4. 7. Patients requiring long-term use of anticoagulants. 8. Patients taking dabigatran, apixaban and/or rivaroxaban (or similar drugs of the same category) before symptoms arise. 9. Bleeding in other sites, including retroperitoneal, gastrointestinal, genitourinary or respiratory tract bleeding; superficial or skin surface bleeding mainly occurring in the vascular puncture site or transvenous approach (eg. arterial puncture, venous incision, etc. ) or in the recent surgical site. 10. May be pregnant in the near future or already pregnant. 11. Previously enrolled in this study. 12. Participating in other interventional medical research or clinical trials at the same time. 13. Patients with severe co-morbidity (including hepatic, renal, gastrointestinal, respiratory, cardiovascular, endocrine, immune and/or hematological disorders) which may affect the outcome assessment. 14. Patients difficult to follow up or with poor compliance due to various reasons (such as geographical and social factors, drug or alcohol abuse, etc.)

Basal ganglion hemorrhage is one of the most common subtypes of cerebral hemorrhage, characterized by high morbidity, mortality, and disability rates. Minimally invasive surgery for cerebral hemorrhage, particularly utilizing a fiber tract-based AI Robot Guiding System, has shown potential advantages for patient prognosis. However, there is currently no standardized practice or robust evidence confirming the effectiveness and safety of this technology for small-volume basal ganglion hemorrhage. Therefore, we are conducting a nationwide, prospective, multicenter randomized controlled clinical trial to evaluate the therapeutic effects of the fiber tract-based artificial intelligence (AI) Robot Guiding System on the perioperative and long-term recovery of patients with small-volume basal ganglion hemorrhage.

Arms

Patients will be operated on minimally invasive puncture and aspiration using Tract-based AI Robot guidance System

Sham Comparator: Conservative Group

Patients will be managed with guideline-based medications without surgery

Interventions

Procedure: - Minimally invasive basal ganglion hematoma evacuation with Tract-based AI Robot Guiding System

Basal ganglion hemorrhage patients will be operated on hematoma puncture and aspiration with Tract-based AI Robot Guiding System

Drug: - "Hemocoagulase Bothrops Atrox for Injection"；"Nicardipine"

Basal ganglion hemorrhage patients will be managed with guideline-based medications without surgery. "Hemocoagulase Bothrops Atrox for Injection" belongs to the drug class of "Hemostatic Agents." "Nicardipine" is a calcium channel blocker (CCB) drug to control blood pressure.
