Correlation of modelling hemodynamic parameters with histological changes in the wall of cerebral aneurysms

Project goals

The number of patients incidentally diagnosed for a brain aneurysm, the rupture of which may lead to the most severe type of stroke, is increasing. Modelling hemodynamics in brain aneurysms tries to describe pathophysiology and the risk of rupture of intracranial aneurysms. In our project we will assess models of hemodynamics based non-invasive radiodiagnostic methods and an in-house mathematical algorithm developed at the Mathematical Institute of the Charles University. The main goal of the project is to correlate parameters of hemodynamics with histological changes of the blood vessels wall of the aneurysm sac in patients operated for ruptured as well as unruptured intracranial aneurysms. Another goal of the project is to evaluate hemodynamics in followed unruptured aneurysms from our multicenter database shared among several neurosurgical centers in the Czech Republic and compare with hemodynamic parameters in ruptured aneurysms. The project will help building a multi-modal platform for studying CFD in brain aneurysms with international cooperation.

    Korelace modelace hemodynamických parametrů s histologickými změnami stěny mozkových aneuryzmat

  • Annotation in Czech

    Roste počet jedinců s náhodně diagnostikovanou mozkovou výdutí, jejíž prasknutí vede k nejtěžší formě cévní mozkové příhody. Metoda počítačového modelování hemodynamiky se snaží popsat patofyziologii a riziko ruptury mozkové výdutě. V našem projektu chceme využít modely hemodynamiky kalkulované na základě neinvazivních radiodiagnostických metod a pomocí vlastního algoritmu vyvinutého v Matematickém ústavu Univerzity Karlovy. Hlavním cílem projektu je u pacientů operovaných pro mozkovou výduť, prasklou i neprasklou, popsat parametry hemodynamiky a tyto korelovat s histologickými změnami cévní stěny vaku aneuryzmatu. Dalším cílem je u skupiny sledovaných neprasklých aneuryzmat, která jsou vedena v multicentrické databázi sdílené několika neurochirurgickými pracovišti v ČR, popsat vývoj hemodynamických parametrů v čase a porovnat s výsledky hemodynamiky prasklých aneuryzmat. Projekt pomáhá vytvářet multioborovou platformu s mezinárodní spoluprácí pro výzkum hemodynamiky mozkových aneuryzmat.

  • Project results evaluation

    The aims of the project were to evaluate histological changes in the wall of the cerebral sac in relation to changes in hemodynamic parameters, to assess hemodynamics in monitored uncracked and operated ruptured aneurysms and to create an interdisciplinary team in the Czech Republic focusing on hemodynamics of cerebral aneurysms. We managed to create a strong multidisciplinary team focusing on brain aneurysms. During the project, the researchers described hemodynamic changes in relation to the development and growth of cerebral aneurysms, hemodynamic changes at the site of rupture of cerebral aneurysms and created laboratory models of several cerebral aneurysms, on which they verified mathematical calculations of hemodynamic parameters. They also performed histological evaluation of 41 brain aneurysms with evaluation of morphological and inflammatory changes in the walls of the cerebral edema. The results were published in a total of 6 articles in journals with IF, part of which was de
