ClinConnect Summary

This clinical trial is looking at a new way to treat a type of stroke called intracerebral hemorrhage, specifically when bleeding occurs in the basal ganglia area of the brain. Researchers want to find out if performing a special surgery to remove the blood (called neuroendoscopic hematoma evacuation) along with giving a medication called methylprednisolone can help patients recover better and have fewer complications compared to the surgery alone. The trial will include adults aged 18 to 80 who have been diagnosed with this type of bleeding and can be treated within 24 hours of the stroke starting.

To be part of this trial, participants need to meet certain criteria, like having a specific amount of bleeding in their brain and a certain level of consciousness. If eligible, participants can expect to undergo the surgery and receive the medication while being closely monitored for their recovery. It's important to note that there are strict guidelines for who can join, such as not having other types of bleeding or serious medical conditions. Overall, this trial aims to improve treatment for patients who experience this serious condition.

Eligibility criteria

• Inclusion Criteria:
• • 1. Aged between 18 and 80 years old.
• • 2. Diagnosed with spontaneous intracerebral hemorrhage (ICH) through cranial CT scan, with the bleeding site located in the basal ganglia region.
• • 3. Calculate the hematoma volume based on the cranial CT scan. The volume should range from 30 to 80 ml, and the shift of the mid - line structure at the pineal gland level should be less than 3 mm. The formula for calculating the hematoma volume is V (cm³)=A \* B \* C \* 1/2, where A represents the longest diameter (cm) of the largest hematoma layer in the horizontal position of the plain CT scan, B is the widest diameter (cm) of the hematoma perpendicular to A on this plane, and C is the thickness (cm) of the hematoma shown in the CT images.
• • 4. The time from the onset of the disease to randomization should be within 24 hours. If the actual onset time is unclear, the onset time will be regarded as the time when the subject was last confirmed to be in good health.
• • 5. The National Institutes of Health Stroke Scale (NIHSS) score should be ≥ 6 points at the time of randomization.
• • 6. The Glasgow Coma Scale (GCS) score should range from 5 to 14 points at the time of randomization.
• • 7. The modified Rankin Scale (mRS) score before the onset of the disease should be 0 - 1 points.
• • 8. The patient and their legal representative should sign a written informed consent form.
• Exclusion Criteria:
• • 1. Hemorrhage in other locations (such as hemorrhage in infratentorial regions like the lobes, thalamus, brainstem, or cerebellum).
• • 2. Hemorrhage caused by other reasons (for example, hemorrhage due to aneurysm, arteriovenous malformation, brain trauma, brain tumor, hemorrhagic transformation of large-area cerebral infarction, hemorrhage caused by amyloid angiopathy, hemorrhage resulting from coagulation disorders) or combined with aneurysm, arteriovenous malformation, brain trauma, brain tumor, large-area cerebral infarction, amyloid angiopathy, severe coagulation disorders.
• • 3. Patients with intraventricular hemorrhage or those with intracerebral hemorrhage (ICH) breaking into the ventricles and considered to require external ventricular drainage.
• • 4. A history of any parenchymal brain hemorrhage or other intracranial subarachnoid, subdural, or epidural hemorrhage and a history of relevant surgeries within the recent 30 days.
• • 5. Patients with genetic or acquired bleeding tendencies, coagulation disorders such as deficiency of coagulation factors.
• • 6. Platelet count \< 75 × 10⁹/L.
• • 7. Undergoing anticoagulant drug treatment with warfarin, dabigatran, or rivaroxaban, etc. within one week before enrollment, and having an international normalized ratio (INR) \> 1.4.
• • 8. Expected to require long-term anticoagulation and antiplatelet therapy.
• • 9. A history of previous internal hemorrhage, with risks of gastrointestinal bleeding (such as gastrointestinal ulcers), genitourinary bleeding, or respiratory tract bleeding that has not been fully controlled.
• • 10. Myocardial infarction occurred within the recent 30 days.
• • 11. Known to have a high embolism risk, including patients with mechanical heart valves implanted in the body, a history of left heart thrombus, mitral stenosis accompanied by atrial fibrillation, acute pericarditis, or subacute bacterial endocarditis. Atrial fibrillation without mitral stenosis is eligible.
• • 12. Severe liver function impairment, with alanine aminotransferase (ALT) \> 3 times the upper limit of the normal range, or aspartate aminotransferase (AST) \> 3 times the upper limit of the normal range. Severe renal insufficiency, with a glomerular filtration rate \< 30 ml/min/1.73 m².
• • 13. Patients with Alzheimer's disease or mental disorders who are unable to complete the follow-up plan as required.
• • 14. Complicated by any severe diseases that, upon evaluation, may interfere with the trial results, including diseases of the respiratory system, circulatory system, digestive system, genitourinary system, endocrine system, immune system, and hematopoietic system, etc.
• • 15. Allergic to drugs or devices related to the operation.
• • 16. Pregnant or lactating women, or those planning to become pregnant within one year.
• • 17. In the terminal stage of any disease with an expected lifespan of less than 6 months.
• • 18. Currently participating in other clinical trials or having been previously enrolled in this trial.
• • 19. The patient or his/her legal guardian is unwilling to sign the written informed consent form.
