Considerations and Literature Review for Treating Subarachnoid Hemorrhage due to Blood Blister-Like Aneurysms.

Objective: Subarachnoid hemorrhage (SAH) due to blood blister-like aneurysm (BBA) is rare but very risky during treatment. Moreover, there is no established treatment method. In this study, we performed endovascular treatment (EVT) as the first-line treatment on patients with SAH during the subacute phase, and cases were analyzed in this series.

Mechanical Thrombectomy for Acute Ischemic Stroke Complicated by Bacterial Meningitis and Infective Endocarditis.

Objective: We report a case of cerebral embolism from a bacterial embolus due to infective endocarditis (IE) during treatment of bacterial meningitis.

Case Presentation: During treatment of bacterial meningitis, an 82-year-old woman developed left middle cerebral artery embolism. Mechanical thrombectomy was performed, and the yellowish-white emboli were retrieved.

Correlation between Higher Brain Dysfunction and Cerebral Blood Flow after Carotid Artery Stenting.

Objective: This study investigated the changes in higher brain function and cerebral blood flow (CBF) after carotid artery stenting (CAS), the relationship with CBF, and the impact of high intensities in diffusion-weighted imaging (DWI) after CAS.

Methods: We performed CAS between September 2017 and September 2019 in our department in 88 patients. Patients who did not undergo higher brain function tests according to our protocol or those who did not consent to participate in our study were excluded.

[Intrathecal infusion of the antineoplastic agents for meningeal dissemination].

One of the specific forms of progression of malignant tumors of the central nervous system is meningeal dissemination. Meningeal dissemination is a condition in which tumor cells migrate to the brain surface and sub arachnoid space via cerebrospinal fluid and then infiltrate there. This condition can arise from both primary and metastatic brain tumors, with reported incidences of 4.
