Objective: In coil embolization of ruptured cerebral aneurysms, intraoperative cerebral aneurysm re-rupture and thromboembolism are of concern. A good embolic condition can be expected by adjunctive techniques, but there is an increased risk of complications. We investigated the treatment results by coil embolization procedures for ruptured cerebral aneurysms.

February 2020
Objective: In neuroendovascular therapy, clopidogrel resistance and thrombosis are common problems. In such cases, we use prasugrel as rescue medication, and we clarified its usefulness.
Methods: We retrospectively investigated 199 consecutive cases of neuroendovascular therapy performed at our hospital from April 2016 to March 2018, and examined the safety and effectiveness of prasugrel.
Background And Purpose: Various studies have addressed risk factors for recurrence of ischemic stroke in patients with symptomatic carotid artery stenosis. However, no investigations have compared common localized carotid artery lesions and internal carotid artery lesions, including carotid bifurcation. This retrospective study investigated risk factors for ischemic stroke recurrence in patients with symptomatic carotid artery stenosis, including a comparison of lesion sites.

A simple and rapid assay utilizing aerial microalgae helps to identify stress conditions that can efficiently enhance the carotenogenesis in photosynthetic organisms. The spectra of cell suspensions were characterized in the aerial microalga Coelastrella sp.

- MMP-9 is crucial for blood-brain barrier disruption, and iv-tPA therapy raises its levels. Edaravone, a free radical scavenger, aims to reduce this increase when given alongside low-dose alteplase.
- A study analyzed 63 hospitalized patients after ischemic stroke, measuring several biomarkers over time to see the effects of iv-tPA and Edaravone.
- Results showed that while iv-tPA raised MMP-9 levels, Edaravone's addition did not decrease this increase, nor did MMP-9 levels predict hemorrhagic transformations after the therapy.
Article Synopsis
- Japan has the highest percentage of elderly individuals over 65, accounting for over 20% of its total population, leading to an increase in one-person and older couple households.
- A study involving 253 stroke patients found that living alone or in households with elderly individuals is linked to delayed hospital presentation after a stroke.
- The research indicates that patients from two-person households, especially with both members over 65, experience significant delays in seeking medical help, particularly if the stroke onset occurs at night.
