Summary

The goal of this clinical trial is to determine if direct ischemic post-conditioning (IPostC) can alleviate ischemic-reperfusion injury (I/R) in patients who have undergone endovascular thrombectomy (EVT). Additionally, the study aims to explore the underlying mechanisms of direct IPostC.

The primary questions this trial seeks to answer are:

1. Is direct IPostC effective for acute stroke patients with large vessel occlusion?
2. What are the underlying mechanisms of direct IPostC?

Participants will be randomly assigned to one of two groups: an EVT alone group or an EVT plus direct IPostC group. Direct IPostC will be administered immediately after EVT through four cycles of mechanical interruptions of reperfusion. We will evaluate outcomes based on final infarct volume, infarct volume growth, clinical parameters, and I/R-related imaging and laboratory biomarkers. Additionally, an exploratory multi-omics analysis will be conducted to uncover the detailed mechanisms of direct IPostC.

Conditions

  • Stroke, Acute
  • Neuroprotection
  • Ischemic Conditioning

Interventions

PROCEDURE

Direct Ischemic Post-conditioning

After thrombectomy, the balloon was inflated to a pressure of no more than 4 atm at the occlusion site to block blood flow for 2 minutes, as confirmed by angiography. The balloon was then deflated, allowing blood flow to resume for 2 minutes. These steps were repeated four times.

PROCEDURE

Endovascular therapy

Thrombectomy alone.
