Background: SARS-CoV-2 virus infection leads to a severe and dysbalanced inflammatory response with hypercytokinemia and immunodepression. Systemic inflammation due to viral infections can potentially cause vascular damage including disruption of blood-brain barrier (BBB) and alterations in coagulation system that may also lead to cardiovascular and neurovascular events. Here, we report the first case of COVID-19 infection leading to aneurysmal subarachnoid haemorrhage (aSAH). Case Description A 61-year-old woman presented with dyspnea, cough and fever. She was over weight with Body mass-index of 34 and history of hypertension. No history of subarachnoid hemorrhage in the family. She was admitted in ICU due to low oxygen saturation (89%). A chest CT showed typical picture of COVID-19 pneumonia. Oropharyngeal swab with a PCR-based testing was COVID-19 positive. She was prescribed with favipiravir and hydroxychloroquine in Addition to oxygen support. On second day she experienced sudden headache and losst conciousness. A computer tomography (CT) with CT-angiography revealed subarachnoid haemorrhage in basal cisterns from a ruptured anterior communicating artery aneurysm. The aneurysm was clipped microsurgically through a standard pterional approach and the patient was admitted again to intensive care unit for further intensive medical treatment. Post-operative the patient showed slight motor dysphasia. No other neurological deficits. Conclusion: Aneurysmal subarachnoid haemorrhage secondary to COVID-19 infection might be triggered by systemic inflammation. COVID-19 infection could be one of the risk factors leading to instability and rupture of intracranial aneurysm.

BACKGROUND: There is an increased attention to stroke following SARS-CoV-2. The goal of this study was to better depict the short-term risk of stroke and its associated factors among SARS-CoV-2 hospitalized patients. METHODS: This multicentre, multinational observational study includes hospitalized SARS-CoV-2 patients from North and South America (United States, Canada, and Brazil), Europe (Greece, Italy, Finland, and Turkey), Asia (Lebanon, Iran, and India), and Oceania (New Zealand). The outcome was the risk of subsequent stroke. Centres were included by non-probability sampling. The counts and clinical characteristics including laboratory findings and imaging of the patients with and without a subsequent stroke were recorded according to a predefined protocol. Quality, risk of bias, and heterogeneity assessments were conducted according to ROBINS-E and Cochrane Q-test. The risk of subsequent stroke was estimated through meta-analyses with random effect models. Bivariate logistic regression was used to determine the parameters with predictive outcome value. The study was reported according to the STROBE, MOOSE, and EQUATOR guidelines. FINDINGS: We received data from 26,175 hospitalized SARS-CoV-2 patients from 99 tertiary centres in 65 regions of 11 countries until May 1st, 2020. A total of 17,799 patients were included in meta-analyses. Among them, 156(0.9%) patients had a stroke-123(79%) ischaemic stroke, 27(17%) intracerebral/subarachnoid hemorrhage, and 6(4%) cerebral sinus thrombosis. Subsequent stroke risks calculated with meta-analyses, under low to moderate heterogeneity, were 0.5% among all centres in all countries, and 0.7% among countries with higher health expenditures. The need for mechanical ventilation (OR: 1.9, 95% CI:1.1-3.5, p = 0.03) and the presence of ischaemic heart disease (OR: 2.5, 95% CI:1.4-4.7, p = 0.006) were predictive of stroke. INTERPRETATION: The results of this multi-national study on hospitalized patients with SARS-CoV-2 infection indicated an overall stroke risk of 0.5%(pooled risk: 0.9%). The need for mechanical ventilation and the history of ischaemic heart disease are the independent predictors of stroke among SARS-CoV-2 patients. FUNDING: None.
