Utilizing a Guiding Catheter to Improve Endovascular Therapy Outcomes for Acute Vertebrobasilar Artery Occlusion in Patients with Tortuous Vessels.

 Stable and swift placement of a guiding catheter in endovascular therapies for acute vertebrobasilar artery occlusion is often difficult because of the tortuous bends of the vertebral or subclavian artery especially in older people. The use of a delivery assist guiding catheter (DAGC) shortens the time with stable support to deliver a therapeutic treatment catheter to the target lesions. Herein, we reported the clinical and radiographic outcomes in endovascular therapies utilizing the DAGC for acute vertebrobasilar artery occlusions in actual clinical settings.

Surgical and Endovascular Treatments for Asymptomatic Arteriovenous Fistulas at the Craniocervical Junction: A Multicenter Study.

Objective: Asymptomatic craniocervical junction arteriovenous fistulas (CCJ AVFs) are rare and, thus, a consensus has not yet been reached regarding the indication of surgical interventions. This retrospective multicenter cohort study investigated the risks associated with surgery for asymptomatic CCJ AVFs and discussed the indication of surgical interventions.

Methods: Using data from 111 consecutive patients with CCJ AVFs registered with the Neurospinal Society of Japan between 2009 and 2019, we analyzed the treatment, complications, and outcomes of 18 patients with asymptomatic CCJ AVF.

Detection of Atrial Fibrillation Using Insertable Cardiac Monitors in Patients With Cryptogenic Stroke in Japan (the LOOK Study): Protocol for a Prospective Multicenter Observational Study.

Background: Paroxysmal atrial fibrillation (AF) is a probable cause of cryptogenic stroke (CS), and its detection and treatment are important for the secondary prevention of stroke. Insertable cardiac monitors (ICMs) are clinically effective in screening for AF and are superior to conventional short-term cardiac monitoring. Japanese guidelines for determining clinical indications for ICMs in CS are stricter than those in Western countries.
