Proposal of hematocrit-based non-Newtonian viscosity model and its significance in intracranial aneurysm blood flow simulation

Takashi Suzuki, Katharina Otani
The Jikei University, Japan

Common viscosity models that do not consider patient-specific viscosity variations have been used in computational fluid dynamics (CFD) analyses of intracranial aneurysms (IAs). However, because blood viscosity varies among patients, these results may be unreliable.

Combined Use of X-ray Angiography and Intraprocedural MRI Enables Tissue-based Decision-Making Regarding Revascularization during Acute Ischemic Stroke Intervention

Kerstin Mueller, Himanshu Bhat
University of California, San Francisco, United States

Background For patients with acute ischemic stroke undergoing endovascular mechanical thrombectomy with x-ray angiography, the use of adjuncts to maintain vessel patency, such as stents or antiplatelet medications, can increase risk of periprocedural complications.

Marmoset angiography just by percutaneous puncture of the caudal ventral artery

Katharina Otani
The Jikei University, Japan

Surgery in humans is continuously evolving and promoted minimally invasive treatment. On the other hand, despite the importance of the 3Rs principles for experimental animals is well documented, no reports describe specific methodologies for implementing "refinement" in practice.

Optimal Woven EndoBridge (WEB) Device Size Selection Using Automated Volumetric Software

Sebastian Schaefer
University of Iowa Hospitals and Clinics, USA

Selecting the appropriate Woven EndoBridge (WEB) device sizing for the treatment of wide-neck bifurcation aneurysms (WNBAs) remains challenging. The aim of this study was to evaluate different volumetric-based imaging methodologies to predict an accurate WEB device size selection to result in a successful implantation.

How to iGuide: flat panel detector, CT-assisted, minimally invasive evacuation of intracranial hematomas

Kerstin Mueller, Julie DiNitto
University of California San Francisco

Evidence is growing to support minimally invasive surgical evacuation of intraparenchymal hematomas, particularly those with minimal residual hematoma volumes following evacuation.

"Hemodynamic and Morphological Factors Related to Coil Compaction in Basilar Artery Tip"

Katharina Otani

Coil compaction is directly related to the degree of cerebral aneurysmal recanalization. The degree of recanalization (DoR) was quantified by measuring the volume vacated by coil deformation.
