Pedunculated thrombus in the ascending aorta and aortic arch: About a clinical case

Abstract

Flotant thrombus in the aortic arch without abnormalities is unusual. Arterial embolic disease continues to challenge clinicians. The diagnosis is usually incidental or secondary to a systemic embolism, although there are no randomized controlled trials for consensus as to its treatment. A 54-year-old man was admitted to the critical care resuscitation unit after a nonrevascularizable left middle cerebral ischaemic stroke. CTA with contrast showed a 7-cm pedunculated thrombus in the thoracic aorta originating from the mid ascending aorta and arch, without other abnormalities. Complete removal of the thrombus and complete resection of the basement membrane were performed due to the suspicion of a possible acute aortic syndrome. Histological examination confirmed the presence of fibrin, however, laboratory studies did not establish a main cause that justified the formation of the thrombus.
