Macura KJ, Corl FM, Fishman EK et-al. Distinguishing between the two is often straightforward, but in some instances, no clear continuation of one lumen with a normal artery can be identified. The true lumen is often smaller due to compression by the false lumen 22. Angiography still is required for endoluminal repair. AJR Am J Roentgenol.

The normal lumen lined by intima is called the true lumen and the blood-filled channel in the media is termed the false lumen.

(2018) BMJ (Clinical research ed.). 20. In a very small minority, an underlying connective tissue disorder may be present. Some cases of aortic dissection may result in rupture, causing collapse and often death. Aortic dissection is the prototype and most common form of the acute aortic syndromes and a type of arterial dissection.It occurs when blood enters the medial layer of the aortic wall through a tear or penetrating ulcer in the intima and tracks longitudinally along with the media, forming a second blood-filled channel (false lumen) within the vessel wall. 2009;192 (5): W222-9. CTA has now replaced it as the first-line investigation, not only due to it being non-invasive but also on account of better delineation of the poorly opacifying false lumen, intramural hematoma and end-organ ischemia. 10.

(2015) Circulation journal : official journal of the Japanese Circulation Society. Findings include 1-3,5: An essential part of the assessment of aortic dissection is identifying the true lumen, as the placement of an endoluminal stent-graft in the false lumen can have dire consequences. Most head and neck cancers are derived from the mucosal epithelium in the oral cavity, pharynx and larynx and are known collectively as head and neck … Until the introduction of a sharp drop in 1783, this resulted in a long and painful death by strangulation (friends of the convicts often helped put them out of their misery by pulling on their legs). Depending on the extent of dissection and occlusion of aortic branches, end-organ ischemia may also be present (seen in up to 27% of cases) 5, including: If the aortic dissection involves the aortic root it may result in involvement of the coronary arteries and can present similarly to ST-elevation myocardial infarction on an ECG. 2012;19 (4): 309-15.

It arises from the upper border of the scapula. The CTA radiology report should include at least: Transesophageal echocardiography (TOE) has very high sensitivity and specificity for assessment of acute aortic dissection, but due to limited access and its invasive nature, it has largely been replaced by CTA (or MRA in some instances) 5. 2019]. 123 (20): 2213-8. 2003;181 (2): 309-16. 2007;24 (4): 310. Non-contrast CT may demonstrate only subtle findings; however, a high-density mural hematoma is often visible. 79 (3): 567-73.

Two classification systems are in common usage, both of which divide dissections according to the involvement of the ascending aorta: In recent years, the Stanford classification has gained favor with cardiothoracic surgeons.

Effects of heart rate on motion artifacts of the aorta on non-ECG-assisted 0.5-sec thoracic MDCT. The duration of aortic dissection is arbitrarily categorized into three phases 18,19: Patients are often hypertensive (although they may be normotensive or hypotensive) and present with anterior or posterior chest pain and a tearing sensation in the chest. A new classification system was proposed which is referred with the acronym DISSECT (duration, intimal tear, size of the dissected aorta, the segmental extent of involvement, clinical complications, and thrombosis of the false lumen) 18.

There may be a difference in blood pressure between the two arms depending on where the dissection occurs. 16. Signs of cardiac tamponade (Beck's triad) may also be encountered if rupture occurs into the pericardial space. Gleeson CE, Spedding RL, Harding LA, et al The mediastinum—Is it wide? 13. Complications of all types of aortic dissection include: Specifically, Stanford type A dissection may also result in: Although the combination of blood pressure control and surgical intervention has significantly lowered in-hospital mortality, it remains significant, at 10-35%. This discussion covers neck pain involving the posterior neck (not pain limited to the anterior neck) and low back pain, but it does not cover most major traumatic injuries (eg, fractures, dislocations, subluxations).
