Purpose: Hemodynamics play a key role in the management of cerebral aneurysm recanalization after coil embolization; however, the most reliable hemodynamic parameter remains unknown. Previous studies have explored the use of both spatiotemporally ave

Cerebral proliferative angiopathy (CPA) is a rare vascular abnormality characterized by transdural supply, stenoses of feeding arteries, and intermingled normal brain parenchyma in abnormal vessels. CPA is often regarded as a separate entity from “

Prediction models for post-embolization recurrence with hemodynamic parameters from computational fluid dynamics (CFD) were widely studied to manage cerebral aneurysms. However, only spatiotemporally averaged or maximal scalars were used to develop t

Objective: Cerebral angiography is indispensable for endovascular neurosurgeons. However, there is no established system to evaluate the competency of trainees. We established a scoring system and statistically analyzed its characteristics. Methods:

Introduction Hemorrhage from a recurrent aneurysm is a major concern after coiling for intracranial aneurysms. We aimed to identify aneurysm recurrence patterns associated with hemorrhage. Material and methods We investigated radiological data of pat

An unruptured aneurysm was incidentally found in the right middle cerebral artery in a 67-year-old woman. During an attempt to turn the temporalis muscle for surgical clipping, systolic blood pressure suddenly increased. After opening the dura mater,

Minimum wall shear stress (Min-WSS) points may be associated with wall instability of unruptured cerebral aneurysms. We aimed to investigate the relationship between the locations of Min-WSS points and their underlying intra-aneurysmal flow structure

Large or giant paraclinoid aneurysms typically have good indication for flow diverter (FD) treatment. Here, we report a very rare case of a patient with an unruptured supraclinoid large aneurysm who underwent FD deployment with coil embolisation that
