Endovascular repair of a mycotic thoracic aortic aneurysm in a patient with aortic coarctation

This report describes the management of a 28-year-old female patient who presented with septicemia and mediastinal mass-effect secondary to a proximal mycotic aneurysm of the descending aorta. The patient had an infected bicuspid aortic valve, aortic coarctation, and a left vertebral artery arising directly from the aortic arch. Evidence of disseminated embolization affecting her posterior cerebral circulation, the left axillary, and the superior mesenteric arteries was noted. The patient had a considerably small aorta. An urgent thoracic endovascular aortic repair was performed successfully with a chimney stent to the left vertebral artery. The report discusses the planning and technique used in managing this complex case.
