Thoracic Aortic Aneurysm (TAA) is characterized by the dilation of the aorta and is fatal if not diagnosed and treated appropriately. The underlying genetic mechanisms have not been completely delineated so better knowledge of the physiopathology of TAAs is needed to improve detection and therapy. ...
Interventions are generally considered when the ascending thoracic aorta reaches 5.5 cm or the descending thoracic aorta reaches 6 cm in asymptomatic patients. Smaller aneurysms are followed annually, either by CT or magnetic resonance imaging (MRI). Patients with congenital aneurysms or connective tissue...

Thoracic aortic aneurysm (TAA) is a serious condition that affects the aorta, characterized by the dilation of its first segment. The causes of TAA (e.g., age, hypertension, genetic syndromes) are heterogeneous and contribute to the weakening of the aort
Dilation-dependent activation of platelets and prothrombin in human thoracic ascending aortic aneurysm OBJECTIVE: The purpose of this study was to investigate whether thoracic ascending aortic aneurysm (TAAA) induces platelet activation as mural thrombus par...

Aneurysmal dilation of saphenous vein grafts is a relatively rare complication of the now common surgical procedure of coronary artery bypass graft (CABG) surgery. The true prevalence of this condition is not clear, however, literature review by Jorgense
A little later, the patient’s mother passed away suddenly at the age of 59, and autopsy revealed a dissection of the thoracic aorta. Despite strong advisement against pregnancy due to the significant risks associated, particularly before undergoing repair of the ascending aortic aneurysm, the ...

(B) In another patient, in a T1-weighted spin echo MR image obtained 40 days after the onset, an intramural hematoma of the ascending thoracic aorta shows high signal intensity (arrow) caused by the presence of methemoglobin (subacute stage). Penetrating atherosclerotic ulcer Penetrating ...
Because the sinuses of Valsalva lie completely within the cardiac silhouette (Fig. 11-25), the discrete type of aneurysm is not visible on the plain chest film. If the ascending aorta is also dilated, the right side of the mediastinum will have the characteristic convexity of the aorta as ...
