Consecutive ischemic stroke and TIA admissions (COVID and non-COVID) to the authors' hospital during a 10-week period from March 1 to May 10, 2020 were collected and compared with data from the same time period in 2019. Among 20 patients with COVID-19 and acute ischemic stroke, 15 (75%) had large-vessel occlusion. These patients were young (mean age, 46.5 years), male (93%), without major burden of traditional cardiovascular risk factors, and had a severe stroke presentation. Large vessel occlusions were observed in multiple vessels (40%), uncommonly affected vessels, and atypical locations with a large thrombus burden.

In a retrospective multicenter study, all patients treated with the FRED for a ruptured intracranial blister-like aneurysm between January 2013 and May 2019 were analyzed. In total, 30 patients with 30 ruptured blister-like aneurysms were treated. Immediate complete aneurysm obliteration with the FRED was achieved in 10 patients (33%). Of the 26 patients with follow-up, complete obliteration was achieved in 21 patients (80%) after 6 months and in 24 patients (92%) in the final follow-up (median, 22 months). The authors conclude that treatment of ruptured blister-like aneurysms with the FRED is safe and effective.
