TEVAR Stent to the False Lumen of a Chronic Type B Aortic Dissection With Aneurysmal Dilatation, When no Other Options Are Left

Abstract

We report a case of a 72 years-old male referred to us with a 2-year history of an enlarging aortic aneurysm secondary to a chronic Type B aortic dissection and a complete occlusion of the true lumen in the thoracic and abdominal aorta except at the level of visceral arteries origins. Several attempts to recanalize the true lumen was not successful. Because of the patient's high risk for an open repair and the normal size of his thoracic aorta proximal to the celiac artery, we deployed the TEVAR stent to the false lumen to prevent aneurysmal enlargement and rupture. The operation was successful, and the patient recovered without complications and with complete exclusion of the aneurysm on two years follow up.
