Case ReportsCerebral Venous Thrombosis in Patients with COVID-19 Infection: a Case Series and Systematic Review.
There has been increasing reports associating the coronavirus disease 2019 (COVID-19) with thromboembolic phenomenon including ischemic strokes and venous thromboembolism. Cerebral venous thrombosis (CVT) is a rare neurovascular emergency that has been observed in some COVID-19 patients, yet much remains to be learnt of its underlying pathophysiology. ⋯ The high mortality rate of CVT in COVID-19 infection warrants a high index of suspicion from physicians, and early treatment with anticoagulation should be initiated.

Association of Serum Complement C1q Concentration with Severity of Neurological Impairment and Infarct size in Patients with Acute Ischemic Stroke.
Inflammation occurs after acute ischemic stroke (AIS), and complement C1q is involved in inflammation. However, studies about the association of complement C1q with AIS are still rare. The aim of our study is to investigate the relationship between serum C1q concentration and the clinical severity of AIS. ⋯ Serum C1q concentration was positively associated with DMTS and NIHSS of patients with AIS.

Case ReportsLeft Atrial Spinning Ball Thrombus in a Patient with Cardioembolic Stroke: A Case Report.
A left atrial movable ball thrombus is unusual and may cause fatal systemic emboli or left ventricular inflow obstruction. Among movable ball thrombi, a spinning ball thrombus is a rare and devastating occurrence that results in cardioembolic stroke. Here, we report the case of an 88-year-old woman with a large spherical thrombus spinning in the left atrium when a catastrophic cardioembolic stroke recurred. ⋯ Transthoracic echocardiography revealed a large detached spherical thrombus spinning in the left atrium. She did not recover consciousness and was moved to another hospital for palliative care three months later. Movable type left atrial thrombi are regarded as a high risk for thromboembolic events, but those with spinning movements may have a worse prognosis.
