Med."],"abstract":"<jats:p>The treatment of ischaemic stroke increasingly relies upon endovascular procedures known as mechanical thrombectomy (MT), which consists in capturing and removing the clot with a catheter-guided stent while at the same time applying external aspiration with the aim of reducing haemodynamic loads during retrieval. However, uniform consensus on procedural parameters such as the use of balloon guide catheters (BGC) to provide proximal flow control, or the position of the aspiration catheter is still lacking. Ultimately the decision is left to the clinician performing the operation, and it is difficult to predict how these treatment options might influence clinical outcome. In this study we present a multiscale computational framework to simulate MT procedures. The developed framework can provide quantitative assessment of clinically relevant quantities such as flow in the retrieval path and can be used to find the optimal procedural parameters that are most likely to result in a favorable clinical outcome. The results show the advantage of using BGC during MT and indicate small differences between positioning the aspiration catheter in proximal or distal locations. The framework has significant potential for future expansions and applications to other surgical treatments.<\/jats:p>","DOI":"10.3389\/fcvm.2023.1117449","type":"journal-article","created":{"date-parts":[[2023,3,15]],"date-time":"2023-03-15T05:43:03Z","timestamp":1678858983000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":7,"title":["A multiscale computational framework to evaluate flow alterations during mechanical thrombectomy for treatment of ischaemic stroke"],"prefix":"10.3389","volume":"10","author":[{"given":"Ivan","family":"Benemerito","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Mustafa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ana Paula","family":"Narata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Narracott","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alberto","family":"Marzo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2023,3,15]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"e153","DOI":"10.1161\/CIR.0000000000001052","article-title":"Heart disease and stroke statistics\u20142022 update: a report from the American heart association.","volume":"145","author":"Tsao","year":"2022","journal-title":"Circulation."},{"key":"B2","doi-asserted-by":"publisher","first-page":"2309","DOI":"10.1161\/STROKEAHA.106.475483","article-title":"Comparison of clinical characteristics and functional outcomes of ischemic stroke in different vascular territories.","volume":"38","author":"Ng","year":"2007","journal-title":"Stroke."},{"key":"B3","doi-asserted-by":"publisher","first-page":"317","DOI":"10.1136\/jnnp.74.3.317","article-title":"Incidence, risk, and case fatality of first ever stroke in the elderly population.
