Angiography still is required for endoluminal repair. Emergency Medicine Journal 2001;18:183-185. AJR Am J Roentgenol. 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. Acute dissection of the descending aorta: noncommunicating versus communicating forms. Gleeson CE, Spedding RL, Harding LA, et al The mediastinum—Is it wide? Emerg Radiol. Contrast-enhanced CT (preferably CTA) gives excellent detail. In a very small minority, an underlying connective tissue disorder may be present. It arises from the upper border of the scapula. Access to abstracts is complimentary. (2018). It has reported sensitivity and specificity of nearly 100% 3,5. 8. Ko JP, Goldstein JM, Latson LA, Azour L, Gozansky EK, Moore W, Patel S, Hutchinson B. Emerg Med J. 23. Aortic dissection: diagnosis and follow-up with helical CT. Radiographics. In most cases the vessel wall is abnormal. It has similar sensitivity and specificity to CTA and TOE 5 but suffers from limited availability and the difficulties inherent in performing MRI on acutely unwell patients. AJR Am J Roentgenol. Specifically, Stanford type B dissection the false lumen may 23: The differential on chest x-ray is that of a dilated thoracic aorta. The normal lumen lined by intima is called the true lumen and the blood-filled channel in the media is termed the false lumen. Hurwitz LM, Goodman PC. Distinguishing between the two is often straightforward, but in some instances, no clear continuation of one lumen with a normal artery can be identified. 22. Lepage MA, Quint LE, Sonnad SS et-al. However, treating these patients with antiplatelets/anticoagulation could be disastrous in aortic dissection. 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%. On CT, a number of entities that can mimic a dissection should be considered 5: Clinically, a number of causes of acute chest pain are often considered: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys.

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. 46 (2): 175-90. There may be a difference in blood pressure between the two arms depending on where the dissection occurs. 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). Neck pain and back pain are among the most common reasons for physician visits. 17. (2011) Circulation. 19 (1): 45-60. 2005;184 (4): 1225-30. Causes include: The false lumen typically has higher and less pulsatile pressure, thought to be due to reduced distal outflow. Published eight times a year, Annals includes original research articles, basic science research, surgical notes and techniques, reviews and case reports. Non-contrast CT may demonstrate only subtle findings; however, a high-density mural hematoma is often visible. 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. 9. de Lacey G, Morley S et-al. The true lumen is often smaller due to compression by the false lumen 22. 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. 20. 16. 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 … 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.
