Abstract 198: Endovascular Biopsy: in vivo Brain Aneurysm Endothelial Cell Sampling and Gene Expression Analysis

Introduction: Cerebral aneurysms affect 1-6% of the population and their rupture carries significant mortality and morbidity. The paucity of data related to histopathological features of aneurysms stems largely from the risks associated with aneurysm tissue collection. We set out to establish a feasible technique to isolate viable endothelial cells (EC) and to characterize the differences in genetic expression (GE) between iliac arterial cells...
