Aortic dissection is an emergent medical condition, generally affecting the elderly, characterized by a
separation of the aortic wall layers and subsequent creation of a pseudolumen that may compress the true aortic lumen.
Predisposing factors mediate their risk by either increasing tension on the wall or by causing structural degeneration. They
include hypertension, atherosclerosis, and a number of connective tissue diseases. If it goes undetected, aortic dissection
carries a significant mortality risk; therefore, a high degree of clinical suspicion and a prompt diagnosis are required to
maximize survival chances. Imaging methods, most commonly a CT scan, are essential for diagnosis; however, several
studies have also investigated the effect of several biomarkers to aid in the detection of the condition. The choice of
intervention varies depending on the type of dissection, with open surgical repair remaining of choice in those with type.
A dissections; however, the role of conventional open surgery has considerably diminished in complicated type B
dissections, with endovascular repair, a much less invasive technique, proving more effective. In uncomplicated type B
dissections, where medical choice reigned supreme as the optimal intervention, endovascular repair is being explored as a
viable option which may reduce long term mortality outcomes, although the ideal intervention in this situation is far from
settled.
