Although TEVAR is an established treatment option for thoracic aortic disease, the suitability of the proximal and distal landing zones remains one of the main limitations for its use. Complex endovascular and hybrid techniques have been described, and although effective in such scenarios, require significant skills and are prone to complications. Custom-made scalloped stent grafts are easier to plan and deploy, and when feasible, allow the treatment of these lesions with limited endovascular maneuvers, shorter surgical times and less risk of complications. These scallops can be placed either proximally or distally in the endograft, depending on the target vessel to preserve, and are therefore useful in different aortic anatomies unsuitable for conventional endografting. Through this article, the authors presented three cases of thoracic aortic aneurysm, with three different hostile anatomies, successfully treated with custom-made scalloped stent grafts.
