Abstract WMP27: PAT Model Accurately Predicts Aneurysm Enlargement in 16 Growing Aneurysm Cases

Autor: Aneurysm Genetics Investigators, Satoshi Tateshima, Wang Anthony, J. P. Villablanca, Aichi Chien, Noriko Salamon, Szeder Viktor, Reza Jahan, Geoffrey P. Colby, Michelle A.T. Hildebrandt, Fernando Vinuela, Gary Duckwiler, Victor Chang

Publikováno v: Stroke. 51

Objective: Imaging technology for unruptured intracranial aneurysms (UIA) has improved detection of such aneurysms. However, there is limited information on UIA change over time, and how to predict the rate of enlargement. The objective of this study

Publikováno v: Oral Abstracts.

Purpose The growth or rupture of cerebral aneurysms is thought to be a complex arterial wall response caused by an interaction of biological and hemodynamic factors. Current approaches that analyze the effects of flow stress on vascular cells are lim

Publikováno v: Journal of neurosurgery. 132(4)

OBJECTIVEAs imaging technology has improved, more unruptured intracranial aneurysms (UIAs) are detected incidentally. However, there is limited information regarding how UIAs change over time to provide stratified, patient-specific UIA follow-up mana
