Aortic unfolding is an abnormality visible on a chest X-ray, that shows widening of the mediastinum which may mimic the appearance of a thoracic aortic aneurysm. [1]With aging, the ascending portion of the thoracic aorta increases in length by approximately 12% per decade, whereas the diameter increases by just 3% per decade.
A stent graft placed in the thoracic aorta to treat a thoracic aortic aneurysm. The size cut off for aortic aneurysm is crucial to its treatment. A thoracic aorta greater than 4.5 cm is generally defined as aneurysmal, while a size greater than 5.5 cm is the distinction for treatment, which can be either endovascular or surgical, with the ...
Acute aortic syndrome (AAS) describes a range of severe, painful, potentially life-threatening abnormalities of the aorta. [1] These include aortic dissection, intramural thrombus, and penetrating atherosclerotic aortic ulcer. [2] AAS can be caused by a lesion on the wall of the aorta that involves the tunica media, often in the descending ...
The most common mechanism leading to thoracic aortic injury is a motor vehicle collision. Other mechanisms include airplane crashes, falling from a large height and landing on a hard surface, or any injury that causes substantial pressure to the sternum. [10] The incidence of thoracic aortic injuries is approximately 1 in 100,000. [6]
The aortic wall dilatation at the commissural level causes the cusps to effectively shorten and prevent them from converging during systole, which results in aortic valve incompetence. The arch is typically spared from the aneurysmal process, though it may involve the entire ascending aorta. The ectatic aorta may experience dissections.
The pattern of pulse abnormalities is dependent upon the classification; e.g., for type B interrupted aortic arch, the right brachial pulse will be palpable and the left brachial and femoral pulses will be impalpable due to closure of the ductus arteriosus. [3] Rarely, an interrupted aortic arch can be associated with an intracranial aneurysm. [6]
Ritter Rules are a compilation of reminders, symptoms, and risk factors designed to prevent the misdiagnosis of thoracic aortic dissection. [54] The rules were named after Three's Company star John Ritter, who died from a thoracic aortic dissection in 2003 after he was misdiagnosed and falsely treated for a heart attack by his two doctors.

Generally, diseases outlined within the ICD-10 codes S00-S09 within Chapter XIX: Injury, poisoning and certain other consequences of external causes should be included in this category. Chest trauma is an injury to the chest .
