    The DeBakey classification, along with the Stanford classification, is used to separate aortic dissections into those that need surgical repair, and those that usually require only medical management. Classification. The DeBakey classification divides dissections into 1-5: type I: involves ascending and descending aorta (= Stanford A) aortic dissection include a new heart murmur, weak pulses in the feet or wrists, or a significant difference in the blood pressure measurement between the right and left arms.5 How is aortic dissection diagnosed? When the diagnosis of aortic dissection is suspected, accurate imaging studies must be performed immediately. Aortic dissection is relatively uncommon. The condition most frequently occurs in men in their 60s and 70s. Symptoms of aortic dissection may mimic those of other diseases, often leading to delays in diagnosis. However, when an aortic dissection is detected early and treated promptly, the chance of survival greatly improves.

Complicated dissection refers to evidence of thoracic aortic rupture (blood outside the aortic wall), malperfusion (ischemia that involves the viscera, kidneys, spinal cord, or lower extremities), or rapid expansion in the distal arch or proximal descending aorta to a total aortic diameter of 4.5 cm or greater. Type A dissections are usually managed surgically with aortic root replacement.. Type B dissections are usually managed with endoluminal approaches and medical management..

Blood pressure should be controlled as rapidly as possible aiming for a systolic blood pressure of 120mmHg or even less using ... Abstract. CT angiography (CTA) is a well established first line imaging modality used to assess diseases of the vasculature. In recent years new technologies, such as cardiac-gating, dual energy, high-pitch helical scanning, and iterative reconstruction have offered new and innovative means of imaging diseases of the thoracic aorta.
