Abstract
A single-center, retrospective, cohort study was performed from January 2005 to May 2019. Of 391 patients evaluated for thoracic endovascular aortic repair (TEVAR), 9 (2%) had had shaggy thoracic aortic aneurysms, defined as an ulcerated atheroma or thrombus thickness ≥5 mm protruding into the aortic lumen and/or occupying more than two thirds of the aortic circumference on computed tomography angiography. Two of the nine patients had presented with blue toe syndrome. Of the seven patients who had undergone TEVAR, embolization occurred in one patient (transient ischemic attack and acute kidney injury) and possibly in another patient who had developed spinal cord ischemia. The risk of atheroembolism in shaggy thoracic aortic aneurysm is a threatening complication but TEVAR proved effective.
