Dissection of the descending part of the aorta (3), which starts from the left subclavian artery and extends to the abdominal aorta (4). The ascending aorta (1) and aortic arch (2) are not involved. Specialty Vascular surgery, cardiothoracic surgery Symptoms severe chest or back pain, vomiting, sweating, lightheadedness[1][2] Complications Stroke, mesenteric ischemia, myocardial ischemia, aortic rupture[2] Usual onset Sudden[1][2] Risk factors High blood pressure, Marfan syndrome, bicuspid aortic valve, previous heart surgery, major trauma, smoking[1][2][3] Diagnostic method Medical imaging[1] Prevention Blood pressure control, not smoking [1] Treatment Depends on the type[1] Prognosis Mortality without treatment 10% (type B), 50% (type A)[3] Frequency 3 per 100,000 per year[3]
Aortic dissection occurs when an injury to the innermost layer of the aorta allows blood to flow between the layers of the aortic wall, forcing the layers apart.[3] In most cases this is associated with a sudden onset of severe chest or back pain, often described as “tearing” in character.[1][2] Also, vomiting, sweating, and lightheadedness may occur.[2] Other symptoms may result from decreased blood supply to other organs such as stroke or mesenteric ischemia.[2] Aortic dissection can quickly lead to death from not enough blood flow to the heart or rupture of the aorta.[2]
