This article discusses the use of endovascular stent-graft placement as a treatment for acute aortic dissection. The study involved 19 patients with acute aortic dissections, including 4 with type A and 15 with type B dissections. The primary entry tear was covered with stent-grafts, which are self-expanding stainless-steel devices covered with woven polyester or polytetrafluoroethylene. The procedure was technically successful in all patients, with complete thrombosis of the false lumen achieved in 15 patients (79%) and partial thrombosis in 4 (21%). Revascularization of ischemic branch vessels occurred in 76% of obstructed branches. The early mortality rate was 16%, with no deaths or aneurysm/rupture during the 13-month follow-up. The results suggest that stent-graft coverage of the primary entry tear may be a promising treatment for selected patients with acute aortic dissection, although further evaluation is needed to fully assess its therapeutic potential.This article discusses the use of endovascular stent-graft placement as a treatment for acute aortic dissection.
