This defect may be found anywhere from just above the semilunar valves to the more distal ascending aorta and main pulmonary artery.
At this site, all the major and cranial arteries, such as the brachiocephalic trunks, the ascending aorta, the brachial arteries, the carotid arteries, the pulmonary arteries, and the jugular veins, can easily be identified (Figs 10 through 12).
The ascending aorta was replaced and the vein grafts reimplanted.
In cases of internal jugular vein CVCs, intraarterial misplacement may not be apparent in routine x-rays when the CVC is in the ascending aorta because of overlap of the superior vena cava and the aorta.
The points of greatest hydraulic stress in the aorta are the most common locations of intimal tearing: the right lateral aspect of the ascending aorta and the descending thoracic aorta proximal to the ligamentum arteriosum.
Magnetic resonanace (MR) and computed tomography (CT) angiography with three-dimensional (3D) reconstruction provides excellent visualisation of the ascending aorta and aortic arch and should be used to delineate the extent of SVAS and other arteriopathies.
Echocardiography and computed tomography established the diagnosis of ascending aorta dissection.
This is what every surgeon would love to do in treating an ascending aortic dissection: They would treat a limited tear in the proximal ascending aorta above the aortic valve that ended above the brachiocephalic vessels.
Type A aortic dissections begin in the ascending aorta, the segment closest to the heart, and require surgery to repair.
On July 31, 2010, the aortic valve (bioprosthesis) and proximal portion of the ascending aorta were replaced (the latter was a homograft), the paravalvular abscess was debrided, and the coronary ostial sites were implanted into the homograft.
