  2. Ascending aorta - Wikipedia

    en.wikipedia.org/wiki/Ascending_aorta

    A thoracic aorta diameter greater than 3.5 cm is generally considered dilated, whereas a diameter greater than 4.5 cm is generally considered to be a thoracic aortic aneurysm. [4] Still, the average diameter in the population varies by for example age and sex.

  3. Aneurysm of sinus of Valsalva - Wikipedia

    en.wikipedia.org/wiki/Aneurysm_of_sinus_of_Valsalva

    The aorta normally has three small pouches that sit directly above the aortic valve (the sinuses of Valsalva), and an aneurysm of one of these sinuses is a thin-walled swelling. Aneurysms may affect the right (65–85%), non-coronary (10–30%), or rarely the left (< 5%) coronary sinus. [ 1 ]

  4. Thoracic aorta injury - Wikipedia

    en.wikipedia.org/wiki/Thoracic_aorta_injury

    Radiographically this would be seen as an intimal flap less than 1 cm in size. [8] Between the mobile ascending aorta and the relatively fixed descending thoracic aorta is the aortic isthmus. When there is a sudden deceleration the mobile ascending aorta pushes forward creating a whiplash effect on the aortic isthmus. [9] However, a different ...

  5. Thoracic aortic aneurysm - Wikipedia

    en.wikipedia.org/wiki/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 former reserved for pathology at the descending aorta. [12] [13]

  6. Aneurysm - Wikipedia

    en.wikipedia.org/wiki/Aneurysm

    An aneurysm is usually defined as an outer aortic diameter over 3 cm (normal diameter of the aorta is around 2 cm), [17] or more than 50% of normal diameter that of a healthy individual of the same sex and age. [9] [18] If the outer diameter exceeds 5.5 cm, the aneurysm is considered to be large. [16] The common iliac artery is classified as: [19]

  7. Familial aortic dissection - Wikipedia

    en.wikipedia.org/wiki/Familial_aortic_dissection

    Familial aortic dissection or FAD refers to the splitting of the wall of the aorta in either the arch, ascending or descending portions. FAD is thought to be passed down as an autosomal dominant disease and once inherited will result in dissection of the aorta, and dissecting aneurysm of the aorta, or rarely aortic or arterial dilation at a young age.

  8. Loeys–Dietz syndrome - Wikipedia

    en.wikipedia.org/wiki/Loeys–Dietz_syndrome

    Loeys–Dietz syndrome (LDS) is an autosomal dominant genetic connective tissue disorder. It has features similar to Marfan syndrome and Ehlers–Danlos syndrome. [3] [4] [5] The disorder is marked by aneurysms in the aorta, often in children, and the aorta may also undergo sudden dissection in the weakened layers of the wall of the aorta.

  9. Endovascular aneurysm repair - Wikipedia

    en.wikipedia.org/wiki/Endovascular_aneurysm_repair

    Endovascular aneurysm repair (EVAR) is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair."
