BASIS Technique for Endovascular Therapy of Acute Large Vessel Occlusion Strokes Due to Intracranial Atherosclerotic Disease

This study will explore the safety and efficacy of BASIS technology in ICAS-LVO lesions through a multicenter, prospective, registry, observational single-arm study.By registering intraoperative recanalization using this technique time, recanalization grade, operative thrombectomy times, intraoperative complications perforating branch occlusion, vascular dissection, vascular rupture, Ectopic thrombus, probability of symptomatic intracranial hemorrhage, mRS Score and mortality rate were followed up for 3 months The unique advantages of the application of the assessment BASIS in this type of lesion provide new insights into complex lesions such as ICAS-LVO The thought and operation method can shorten the operation time, improve the good prognosis, reduce the economic burden and reduce the operation Complications make a positive contribution to ensure that patients receive safe, effective and precise treatment.
