Application progress of three dimensional printing technology in diagnosis and treatment of intracranial aneurysms / 中国脑血管病杂志

ABSTRACT

The therapeutic strategies of intracranial aneurysms include surgical clipping and endovascular embolization. Surgical clipping is still challenging for complex aneurysms with various configurations and complicated vasculatures. Endovascular treatment is risky for aneurysms with tortuous routes that make superselections of microcatheter difficult. Three dimensional(3D) printing technology can replicate aneurysm and its related vessels,then help doctors optimize the surgical or endovascular plan preoperatively and provide guidance intraoperatively, thus might improve treatment effects and reduce complications. The progress of 3D printing technique in the treatment of intracranial aneurysms will be reviewed.
