RÉSUMÉ
INTRODUCTION: Cerebral venous sinus thrombosis (CVST) is an uncommon but fatal cause of stroke worldwide. Endovascular treatments could be life-saving in patients who don't treat with anticoagulants as a mainstay of treatment. Currently, there is no consensus considering the safety, efficacy, and also selected approaches of endovascular intervention for these patients. This systematic review evaluates the literature on endovascular thrombolysis (EVT) in CVST patients. MATERIALS AND METHODS: A comprehensive search was conducted through PubMed and Scopus databases between 2010 and 2021, with additional sources identified through cross-referencing. The primary outcomes were the safety and efficacy of EVT in CVST, including catheter-related and non-catheter-related complications, clinical outcomes, and radiological outcomes. RESULTS: A total of 10 studies comprising 339 patients were included. Most of the patients presented with headaches (86.72%) and/or focal neurologic deficits (45.43%) (modified Rankin Scale of 5 in 55.88%). Acquired coagulopathy and/or consuming estrogen/progesterone medication were the most frequent predisposing factors (45.59%). At presentation, 68.84% had multi-sinus involvement, and 28.90% had venous infarcts and/or intracranial hemorrhage (ICH). The overall complication rate was 10.3%, with a 2.94%, 1.47%, and 1.17% rate of ICH, herniation, and intracranial edema, respectively. The complete and partial postoperative radiographic resolution was reported in 89.97% of patients, increasing to 95.21% during the follow-up. Additionally, 72.22% of patients had no or mild neurologic deficit at discharge, rising to 91.18% at the last follow-up. The overall mortality rate was 7.07%. CONCLUSIONS: EVT can be an effective and safe treatment option for patients with refractory CVST or contraindications to systemic anticoagulation.
RÉSUMÉ
INTRODUCTION: In the context of coronavirus disease 2019 (COVID-19) pandemic, patients with neuromyelitis optica spectrum disorder (NMOSD) are vulnerable to develop COVID-19 due to the immunosuppressive therapy. The objective of this study is to describe a known case of NMOSD on rituximab who experienced 2 episodes of COVID-19. CASE REPORT: A 25-year-old woman, a known case of NMOSD on rituximab was diagnosed with asymptomatic COVID-19. Eight months later, following her last infusion of rituximab, she developed moderate COVID-19. After a partial recovery, she exhibited exacerbation of respiratory symptoms leading to readmission and invasive oxygenation. She was eventually discharged home after 31 days. Her monthly neurological evaluation did not reveal evidence of disease activity. She later received intravenous immunoglobulin and the decision was made to start rituximab again. CONCLUSIONS: Our case raises the possibility of persistent virus shedding and reactivation of severe acute respiratory syndrome coronavirus-2 in a patient with NMOSD and rituximab therapy. We aimed to emphasize a precise consideration of management of patients with NMOSD during the COVID-19 pandemic.
