腹主動脈瘤(abdominal aortic aneurysm , AAA)是腹主動脈較常見的疾病，破裂之后致死率極高，因此，及時發(fā)現(xiàn)和評估AAA破裂的風(fēng)險就具有重要意義。近年來隨著醫(yī)學(xué)影像、計算機(jī)及血流動力學(xué)等理論和技術(shù)的快速發(fā)展，利用計算機(jī)模擬技術(shù)對AAA進(jìn)行仿真研究已成為研究的熱點(diǎn)，其模擬的結(jié)果趨于人體真實(shí)的動脈瘤，并在揭示AAA的發(fā)生及演變的機(jī)制方面發(fā)揮了重要作用。本文介紹了AAA仿真研究的原理及模型分類，詳細(xì)地闡述了瘤體形態(tài)、瘤壁的結(jié)構(gòu)及屬性、血液及血流的屬性、腔內(nèi)血栓等相關(guān)因素在仿真研究中的作用，并對其目前的進(jìn)展及局限性予以綜述。
