Abstract
Surgical treatment of acute DeBakey type I aortic dissection does not address the entire aorta, which can leave anatomically complex residual aortic dissection in the aortic arch and descending aorta. Open repair has been the standard treatment for this pathology. When the lesions are located in the aortic arch, re-do total arch replacement needs to be performed. Plug placement to close small entry tears in the aortic arch has been reported. This article reports about a 79-year-old man who underwent hemiarch replacement for acute DeBakey type I aortic dissection. One year later, his proximal descending aorta dilated to 6.3 cm. The patient was treated with Amplatzer plug in the false lumen, and a stent graft was placed in the true lumen. Follow-up computed tomography scan confirmed complete thrombosis of the false lumen in the descending aorta which had decreased from 6.3 to 4.0 cm. Plug placement in the false lumen in the aortic arch is a potential treatment strategy for anatomically complex residual aortic dissection to induce thrombosis of the false lumen and encourage remodeling.
