A Case of an Intraosseous Arteriovenous Fistula at the Squamous Part of the Occipital Bone with Spontaneous Occlusion of Diploic Venous Drainage.

Objective: An intraosseous arteriovenous fistula (AVF) is a rare fistula with an intracranial shunted pouch. A case of an intraosseous AVF at the squamous part of the occipital bone with spontaneous occlusion of diploic venous drainage is described.

Case Presentation: The patient, a Japanese woman in her 80s, presented with headaches at the back of the head and a history of multiple unruptured cerebral aneurysms but no recent head trauma.

The Usefulness of the 3.1-mm-diameter 4K Rigid Endoscope for Intracerebral Hematoma Evacuation.

The indication for surgical intervention in spontaneous intracerebral hemorrhage remains controversial. Although many clinical trials have failed to demonstrate its efficacy over medical treatment, less invasive endoscopic treatment is expected to demonstrate its superiority. A novel endoscopic system for hematoma removal consisting of a 3.

Safety and Efficacy of Prasugrel Administration in Emergent Endovascular Treatment for Intracranial Atherosclerotic Disease.

Objective: Intracranial atherosclerosis disease (ICAD) is one of the most common causes of acute ischemic stroke. In endovascular treatment (EVT) for acute large vessel occlusion stroke-related ICAD, reocclusion of the recanalized artery due to in situ thrombosis is problematic. In this study, the safety and efficacy of prasugrel administration to avoid reocclusion of emergent EVT for ICAD was investigated.
