[摘要] 顱內動脈瘤(IA)是由顱內動脈病理性、局限性擴張引起的瘤樣突起,其一但破裂可引起蛛網膜下腔出血,造成嚴重后果。目前IA的發病機制仍未闡明,臨床僅能對存在高破裂風險患者進行手術治療,這也使得許多IA患者將無法采取任何治療,并需要承擔IA隨時破裂的風險。因此闡明IA的病因機制,進而研制出針對該疾病病因機制的預防與治療藥物,是解決上述問題的關鍵。由于人體組織較難獲取,IA動物模型便成為主要的研究途徑。本文將從IA動物模型的構建方法、病理改變和藥物治療探索等方面的進展進行綜述,以期為進一步深入研究提供參考。

[Abstract] Intracranial aneurysm (IA) is a tumor like process caused by pathological and localized dilatation of intracranial arteries, once ruptured, it can result in subarachnoid hemorrhage and cause serious consequences. At present, the pathogenesis of IA has yet to be clarified, which result in that onlypatients with high risk of rupture can be treated. Many IA patients have to bear the risk of IA rupture at any time. Therefore, clarifying the mechanism of IA and developing preventive and therapeutic drugsis the key to solve the above problems. Because of the difficulty of obtaining human tissue, IA animal model has become the main research approach. This article will review the progress of IA animal model construction methods, pathological changes and drug treatment, in order to provide reference for further research.

顱內動脈瘤(Intracranial aneurysm,IA)在已知人群中發病率為1%~5%[1],其一旦破裂可引發蛛網膜下腔出血,患者死亡率將高達40%[2],然而其發病機制至今仍未闡明。目前,針對IA的治療主要以血管內介入栓塞或外科手術夾閉IA瘤體為主,以上干預措施可有效防止IA的破裂出血[3]。但是由于不可避免的手術風險和潛在的術后并發癥,臨床上僅建議對存在高破裂風險的IA患者采取手術治療,更多的IA患者只能采取定期復查的處理方式,并承擔一定的心里壓力。因此揭示IA發病機制并開發藥物治療策略是解決上述問題的重要途徑。由于人體組織極難獲取,IA動物模型成為了重要研究工具。
