THORACIC AORTIC ANEURYSM AND ITS DISSECTION

S.B Basnet DMukunda R. Panthee,

Abstract


Neurysms are localized dilatation of the vessel wall, where the diameter of an artery exceeds 1.5 times the normal diameter. Most of the cases with thoracic aortic aneurysm are asymptomatic and aneurysm is detected as an incidental finding on chest radiograph or computed tomography (CT)1. Patient may present with symptoms, due to mass effects of aneurysm to adjacent structures; compression to oesophagus (dysphagia), air way compression (dyspnoea), recurrent laryngeal nerve compression (hoarseness), sometimes with fever and pain in case of mycotic cause or pulmonary infection and may present with distal thrombo-embolic manifestation or the event of aneurysm rupture.
