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 aneurysms.They 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 plate.This article describes the current status and future development of these techniques.
