摘      要：To the Editor:In 1996,Parodi et al^([1])introduced the technique of fenestrated endovascular aneurysm repair(f-EVAR)for treatment of pararenal abdominal aortic *** use physician modified stent grafts(PMSGs)for fenestration,which allows for stent grafts to gain sufficient proximal sealing zones and maintain the blood perfusion of visceral arteries.^([2])Stent grafts used in the f-EVAR technique developed from PMSGs to Company Modified Devices(CMDs)and off-the-shelf devices.^([3])To improve the precision of PMSGs and shorten the time of stent graft modification,various techniques that assist in the process of fenestration have been researched and developed,including 3-dimensional(3D)printing technique,the Mixed Reality(MR)technique,and the 3D parametric surface planar topological guide *** article describes the current status and future development of these techniques.
