Robotic Assisted Evacuation of Subacute and Chronic Supratentorial Deep Hypertensive Intracerebral Hemorrhage for Accelerating Functional Rehabilitation (RESCUE-CHAIN): a Multi-center Randomized Controlled Trial
Background: Hypertensive intracerebral hemorrhage (HICH) is a devastating neurological disorder with high mortality and disability rates. Secondary injury following HICH may worsen motor function rehabilitation in subacute and chronic hematoma. Hematoma evacuation has the potential to reduce mass effect and mitigate the neurotoxic effects. A per-protocol analysis identified a significant functional improvement in patients with minimally invasive surgery with thrombolysis achieving end of treatment (EOT) goal ≤ 15mL. However, no surgical management of stabilized subacute or chronic HICH have been reported before. Therefore, we design this study in which we hypothesize this robotic assisted approach to hematoma EOT goal ≤ 15mL would accelerate functional rehabilitation in subacute and chronic HICH patients.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| robotic assisted evacuation | Active Comparator | In the intervention arm, patients will receive stereotactic robotic assisted HICH evacuation according to the protocol under general anesthesia. |
|
| Concomitant care | No Intervention | All enrolled HICH patients in this study will receive standard medical treatment in the first 3-4 weeks according to the ASA/AHA guideline . Continued medical treatment is applied to patients in the control arm. Both arms will receive identical rehabilitation therapy three times per week for 180 days at one facility. Rehabilitation therapy includes identical physical therapy, occupational therapy, speech therapy, functional training, acupuncture and massage. |

| Robotic Assisted Evacuation | Procedure | On the day of surgery, the patient is placed in the prone position. After the Mayfield skull clamp is positioned to reduce interference, the videometric tracker of robot will automatically scan the preliminary markers to complete patient-to-image registration. Following the registration, the robotic arm will move on command according to the planned puncture trajectory and stop at a defined distance to the marked target point. The entry point is marked on the scalp along the puncture trajectory, then a scalp incision and burr-hole drilling will be performed. After penetrating the dura with unipolar electrocautery, a drainage tube will be gently inserted to the defined depth under the indication of the disinfected robotic arm. The liquefied hematoma will be withdrawn slowly by a 10 mL syringe. |

The modified Rankin Scale (mRS) is a single item, global outcomes rating scale for patients post-stroke. It is used to categorize level of functional independence with reference to pre-stroke activities rather than on observed performance of a specific task.

| Extended Glasgow Outcome Scale (eGOS) | The GOS-E adds to the original 5 GOS categories, with 3 additional categories.
