Filter by:The objective of this clinical trial is to determine whether rapid local ischemic postconditioning (RL-IPostC) is effective in preventing brain edema and safe in acute ischemic stroke (AIS) patients treated with mechanical thrombectomy. In this trial, researchers will block antegrade cerebral blood flow temporarily by the way of balloon inflation/deflation in AIS patients immediately after revascularization. It makes the ischemic reperfusion brain tissue have a capacity of adaptation through intermittent blood flow restoration. Researchers will evaluate the protective role and safety of different duration of balloon inflation/deflation. The optimal postconditioning intervention dose will be determined for further confirmative investigation.
This project investigates the impact of statins on cerebral vascular wall damage after mechanical thrombectomy. The investigators will undertake a multi-center, prospective, parallel-controlled, open-label, superiority randomized controlled study based on past research on intense lipid-lowering intervention trials. Patients undergoing post-thrombectomy will be divided into two groups: the test group and the control group. After surgery, the test group will be given a high dose of atorvastatin (80mg/day), followed by a standard dose (20mg/day). The control group will continue to receive the standard dose of atorvastatin (20mg/day). The investigators will compare the high-resolution vascular wall MRI characteristics (vascular wall enhancement, lumen stenosis rate, and so on) within 3-5 days of the operation, as well as the composite incidence of ischemic stroke, transient ischemic attack, intracranial hemorrhage 1 month postoperatively, and the modified Rankin Score at 90 days.
In ischemic stroke, the recanalization rate after intravenous thrombolysis has been estimated to be less than 50% in patients with proximal intracranial artery occlusion; this rate is greater than 80% after endovascular thrombectomy. Thromboelastometry is a method of analysis of coagulation and fibrinolysis in whole blood. The main objective of this study is to evaluate whether the parameters obtained by thromboelastometry are predictive of revascularization at arteriography during mechanical thrombectomy, after treatment with rt-PA thrombolysis.
