简要总结
This is a feasibility study trial to determine whether hyperacute (≤8 hour) mechanical Minimal Invasive Surgical (MIS) management is feasible and secondarily improves outcome in patients with spontaneous supratentorial intracranial hemorrhage (ICH).
Patients meeting the inclusion and exclusion criteria, will be enrolled and randomized to either minimally invasive hematoma evacuation (MIS) or best medical management alone (MM). Subjects will be randomly assigned by a central web-based system in a 3:1 manner to treatment with MIS or MM. Data for each subject will be collected at the time of enrollment and treatment, and at subsequent follow-up visits.
详细描述
The proposed study seeks to determine whether hyperacute (≤8 hour) mechanical MIS management is feasible and improves outcome in patients with spontaneous supratentorial intracranial hemorrhage (ICH).
- Screening The subject will be evaluated as any non-traumatic spontaneous intra-parenchymal hemorrhage patient including medical history screened, available clinical/neurological exams (focused exam, NIHSS, GCS, historical mRS), ECG, laboratory work, and imaging information per institutional standard of care. A CTA (or MRA) will be performed, as standard of care.
- Randomization After all inclusion and exclusion criteria are confirmed and written informed consent obtained, randomization will occur. Subjects will be randomized to best MM or MIS.
- Treatment Procedure (if randomized to MIS) Minimally Invasive Surgical evacuation.
- Treatment Procedure (if randomized to MM) There is no intervention for the control group beyond the current standard of care provided at The Ottawa Hospital. Subjects randomized to the MM group will receive best MM for ICH according to Canadian Best Practice Recommendations for ICH care. Outcomes assessments will be in accordance to table 2.
- Post procedure, D1, D2 and D5 or discharging A post-procedural computed tomographic scan will be obtained within 24 hours (± 6 hours) for MIS group. Clinical assessment such as NIHSS, mRS, NCCT head, computed tomographic Angiogram, adverse event assessment will be conducted as SOC for MIS group (Table 2 in protocol).
A CT will be obtained in MM subjects 24 hours (± 6 hours) after randomization. Adverse event assessment will be conducted for MM subjects 4-6 hours after randomization. Neurological and functional exams will be conducted in D1 and D2 after randomization (Table 2 in protocol).
Follow-up visits (D30, D90): (Both MIS and MM groups) Follow-ups will be combined with phone and onsite visit. D30 will be conducted over the phone, and D90 will be onsite visit. The follow-ups will involve clinical assessment such as NIHSS, Glasgow Coma Scale, EuroQol- 5 Dimension (EQ-5D), mRS, Barthel, Glasgow Outcome Scale (GOSE), adverse event assessment, concomitant. medications.

主要结局
Feasibility of enrolment <=8 hours
时间窗: Baseline
Number of patients eligible for treatment recruited
Quality of life assessment
时间窗: Day 1, Day 5 and Day 90
Quality of life assessed via NIH Stroke Scale 0: No stroke symptoms 1-4: Minor stroke 5-15: Moderate stroke 16-20: Moderate to severe stroke 21-42: Severe stroke Change from Day 1 to Day 90 will be assessed as well
Number of patients with good functional outcome
时间窗: Day 1 (baseline), Day 30 and Day 90
Functional outcome assessed via modified Rankin score (mRS). Change from Day 1 to Day 90 will be assessed (0 no symptoms - 5 severe disability)
Rate of mortality
时间窗: Day 30
Number of deaths
Quality of life EQ-5D-5L
时间窗: Day 90
EQ-5D-5L stands for European Quality of Life Five Dimension, the 5-level EQ-5D version (EQ-5D-5L), which was introduced by European Quality of Life Scale group in 2009. EQ-5D-5L is used for self-assessment on activities of daily living. The EQ-5D-5L comprises five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 5 levels: LEVEL 1: indicating no problem LEVEL 2: indicating slight problems LEVEL 3: indicating moderate problems LEVEL 4: indicating severe problems LEVEL 5: indicating unable to/extreme problems
