False Lumen Patency After Occlusion With Physician-Modified Candy-Plug in Aortic Dissections: A 2-Center Experience

Persistence of false lumen (FL) patency after thoracic endovascular aortic repair (TEVAR) for thoracic aortic dissection (TBAD) remains a significant challenge for physicians. Various strategies have been developed to address retrograde FL patency, including the candy-plug technique. This technique involves modifying thoracic stent grafts and placing an additional plug to occlude the reduced stent graft waist.Since its introduction, three generations of custom-made candy-plug devices (Cook Medical, Bloomington, IN, USA) have been developed. However, delivery times vary across countries and vascular surgery services, complicating procedural planning, particularly in symptomatic patients or cases of rapid FL diameter progression.In this study, we provide a step-by-step description of the physician-modified candy-plug technique and present our preliminary results.
