Transthoracic minimally invasive closure for the treatment of arch penetrating aortic ulcer: a case report

Abstract

Penetrating aortic ulcer (PAU) is one of the three subtypes of acute aortic syndrome. PAUs occur at any point throughout the aorta, most commonly in the descending thoracic aorta and less frequently in the aortic arch. Open surgical repair and total/hybrid endovascular repair are currently available to treat aortic arch PAUs. Herein, we present a patient with aortic arch PAU who underwent transthoracic minimally invasive closure, which is a novel method for the treatment of PAU. We describe a 52-year old Asian man who presented with sudden chest and back pain for 8 h. Computed tomography angiography showed that the PAU occurred in the aortic arch and had a diameter of 16 mm and a depth of 6 mm. The opening was successfully closed via transthoracic minimally invasive closure with an atrial septal defect occluder.
