A clinical study on ‘Intracranial Stenting for Prevention of Ischaemic Stroke’ led by Professor Simon Yu Chun-ho, Professor Wong Ka-sing Lawrence and Professor Leung Wai-hong Thomas, has been carried out jointly in the Vascular and Interventional Radiology Foundation Clinical Science Centre, Department of Imaging and Interventional Radiology and Division of Neurology of Department of Medicine and Therapeutics at CUHK since 2006. The aim of the study was to evaluate the safety and effectiveness of the treatment.

It was found that the success rate of stenting procedure was 95.7%.The study showed that stenting and angioplasty with Wingspan is safe and effective for prevention of stroke, particularly for patients with severe intracranial stenosis (>70%) and with minor ischaemic stroke or symptoms of cerebral ischaemia despite being treated with medical therapy. Relevant articles of the study have been published in the journals American Journal of Neuroradiology (April 2011) and Neurosurgery (August 2011).
