Approaches to global stroke care during the COVID-19 pandemic.
-
Coronavirus disease-2019 (COVID-19) has become a global pandemic. COVID-19 runs its course in two phases, the initial incubation phase and later clinical symptomatic phase. Patients in the initial incubation phase often have insidious clinical symptoms, but they are still highly contagious. ⋯ Although many patients are known for their respiratory symptoms, they had neurological symptoms in their first 1-2 days of clinical symptomatic phase, and ischaemic stroke occurred 2 weeks after the onset of the clinical symptomatic phase. The key is to prevent a patient from progressing to this severe infection from mild infection. We are sharing our experience on prevention and management of COVID-19.

The COVID-19 pandemic has already stressed the healthcare system in the world. Many hospitals have been overwhelmed by the large number of patients with COVID-19. Due to the shortage of equipment and personnel and the highly contagious nature of COVID-19, many other healthcare services are on hold. However, at Beijing Tiantan Hospital, a rapid response system has been in place so that routine care is not interrupted. We, therefore, would like to share our hospital-wide prevention and management policy during this pandemic to help other healthcare systems to function in this crisis. ⋯ A comprehensive policy is helpful to protect the employee from infection and to provide quality and uninterrupted care to all who need these, including patients with acute ischaemic stroke.

Brain arteriovenous malformations (AVMs) are complex and heterogeneous lesions that can rupture, causing significant morbidity and mortality. While ruptured lesions are usually treated, the management of unruptured AVMs remains unclear. A Randomized trial of Unruptured Brain Arteriovenous Malformations (ARUBA) was the first trial conducted to compare the effects of medical and interventional therapy. ⋯ Subsequently, several observational studies were conducted on ARUBA-eligible patients to investigate the safety and efficacy of microsurgery, radiosurgery, and endovascular embolisation over longer follow-up periods. These reports showed that favourable safety profiles and cure rates can be achieved with appropriate patient selection and judicious use of different treatment modalities in multidisciplinary centres. Since large prospective randomised trials on AVMs may not be feasible, it is important to make use of practice-based data beyond the flawed ARUBA study to optimise patients' lifetime outcomes.

Care for acute ischaemic stroke is one of the most rapidly evolving fields due to the robust outcomes achieved by mechanical thrombectomy. Large vessel occlusion (LVO) accounts for up to 38% of acute ischaemic stroke and comes with devastating outcomes for patients, families and society in the pre-intervention era. ⋯ This review article will present a comprehensive overview of LVO management, techniques and devices used, and the future of stroke therapy. In addition, we review our institution experience of mechanical thrombectomy for posterior and distal circulation occlusion.
