Network-Level Brain Dysfunction Beyond the Lesion: A Rare Case of Monakow Syndrome Presenting With Fluctuating Consciousness and Left Hemispatial Neglect Due to Right Anterior Choroidal Artery Infarction

Godai Yawata, Asato Tsuji, Tetsuya Oda, Hirotoshi Hamaguchi

Anterior choroidal artery (AChA) infarction typically manifests as the classical triad of contralateral hemiparesis, hemisensory loss, and homonymous hemianopia (Monakow syndrome). We report a rare case of right AChA infarction presenting with fluctuating consciousness and left hemispatial neglect, accompanied by widespread functional …

An efficient approach for detecting atrial fibrillation in ischemic stroke patients using a wearable device: a prospective multicenter substudy of the STABLED trial

Tomonari Saito, Yasuhiro Nishiyama, Toshiaki Otsuka, Yuki Sakamoto et autres

Objective: Stroke caused by atrial fibrillation (AF) is associated with high mortality and severe morbidity. Screening patients for AF may facilitate early initiation of anticoagulant therapy and prevent recurrent stroke; therefore, strategies to effectively detect AF in stroke patients are important. Methods: …

Mechanical Thrombectomy for N-butyl-2 Cyanoacrylate Cerebral Embolism via Portopulmonary Venous Anastomosis Following Endoscopic Injection Sclerotherapy: A Case Report

Ichiro Maeda, Taichiro Imahori, Shigeru Miyake, Hiroki Goto et autres

Cerebral embolism following endoscopic injection sclerotherapy using N-butyl-2 cyanoacrylate for esophagogastric varices is a rare but serious complication. This condition occurs due to the migration of N-butyl-2 cyanoacrylate into the cerebral circulation, which has traditionally been attributed to paradoxical embolism via a …

Clinical Outcomes of Shifting from Transfemoral-First to Transradial-First Approach in Carotid Artery Stenting: A Retrospective Two-Timeframe Comparison at a Single Center

Taichiro Imahori, Shigeru Miyake, Ichiro Maeda, Hiroki Goto et autres

Objective: Carotid artery stenting (CAS) has traditionally been performed using the transfemoral approach (TFA). Recently, the transradial approach (TRA) has gained attention for its lower invasiveness and reduced complication risk. This study compares outcomes between two access strategy timeframes, TFA-first and TRA-first, …
