About this trial

1. The goal of this clinical trial is to evaluate the efficacy and safety of hyperbaric oxygen (HBO)in stroke patients after endovascular treatment 2. The main questions it aims to answer is:

Whether HBO can improve the prognosis of ischemic stroke patients after endovascular treatment? 3. Participants will:

receive HBO (1.6 Atmosphere Absolute,1.6ATA),Once a day, for 1 hour each time, for 5 days a week (it can be non-consecutive days), the total course of treatment is 10 times.

undergo three scheduled face to face or telephone follow-up assessments during the 12-month period following HBO.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

35-75 years

The symptoms and signs are consistent with acute anterior circulation ischemic stroke. The immediate postoperative angiographic recanalization grade was ≥ 2b.

Neurological deficit score at the time of enrollment: 5 ≤ NIHSS ≤ 15 points

Consciousness status (NIHSS 1a-1b items): 0-1 point

Disqualifiers

Subjects with HBO contraindications or intolerance

Postprocedural imaging identified either procedure-related subarachnoid hemorrhage or hemorrhagic transformation

Based on the medical history, it is suspected that the cerebral embolism is caused by sepsis or infective endocarditis

Expected lifespan < 90 days

Trial outcomes

Primary outcomes

1

The proportion of patients with a favorable prognosis (mRS score of 0-2 ) after randomization at 90 (±7) days

Modified Rankin Scale (mRS) is defined as the gold standard for measuring global functional outcomes after stroke: 0-1 indicating functional independence, 0-2 favorable prognosis, defining functional independence, 4-5 Severely disabled, 6 death. Higher mRS scores indicate worse prognosis.

Time frame
Day 90 (±7) post-randomization

Secondary outcomes

1

Core infarction volume on Diffusion-Weighted Imaging

The effectiveness of HBO for patients with acute ischemic stroke was evaluated based on the core cerebral infarction volume.

Time frame
Day 10 (±1)post-randomization
2

National Institutes of Health Stroke Scale (NIHSS)score [(0, Normal)-(42, worst)]

The effectiveness of HBO therapy in patients with acute ischemic stroke undergoing endovascular treatment was evaluated based on the improvement rate of NIHSS score day 10 post-randomization.

Time frame
Day 10(±1) NIHSS score post-randomization
3

mRS score [ (0, Normal)-(6, worst)]

To assess the effectiveness of HBO treament for ischemic stroke using mRS score on day 10, 30, 90 and 360 post-randomization

Time frame
Day 10 (±1)post-randomization; Day 30(±3) post-randomization; Day 180(±14) post-randomization; Day 360(±30) post-randomization.
4

Distribution of mRS score [(0, normal)-6(worst)]

mRS (0-1): the proportion of functional independence; mRS (0-2): the proportion of good prognosis; mRS (4-6) : the proportion of severe disability.

Time frame
Day 90 (±7) post-randomization
