The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.6 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.6 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00013 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.14 SJR: 0.201 SNIP: 0.313 CiteScore™:: 1.2 H-Index: 13

SINOPSIS

We present flow visualizations of steady and pulsatile flow fields in a cerebrovascular lateral aneurysm model with a wide ostium anchored on a curved parent vessel after stenting, which are complemented by particle tracking velocimetry measurements. Among the stent parameters the blocking ratio Ca ranging from 0% to 75% was selected to study the stent effect on the changes of intra-aneurysmal hemodynamics for the reference of minimally invasive endovascular aneurysm treatment. The Womersley number was 3.9 and the mean, peak, and minimal Reynolds numbers based on the bulk average velocity and diameter of the parent vessel were 600, 850, and 300, respectively. The results are characterized in terms of coded streak images and streamlines. A critical range of Ca related to the inflow location as well as the shape and number of intra-aneurysmal vortices are identified. The intra-aneurysmal flow activity is observed to decrease with increasing Ca. Among the Ca examined, Ca = 75% is the most favorable in attenuating the risk of aneurysmal rupture and promoting intra-aneurysmal thrombus.
