Recent work, however, suggests four distinct time periods: hyperacute (symptom onset <24 hours), acute (2–7 days), subacute (8–30 days), and chronic (>30 days), with a mortality rate that continues to increase significantly even into what is traditionally considered the chronic phase. Although type B dissection is less dangerous than type A, it is still associated with an extremely high mortality. Although risk of rupture is unclear, management of IMH is typically the same as for aortic dissection. Connective tissue disorders affect the integrity of the media of blood vessels and therefore predispose them to rupture of the vasa vasorum. Am J Cardiol 25: 411–5, Pyeritz RE (2000) The Marfan syndrome. The blood supply of the spinal cord was described in some classic works a few decades ago. When uncomplicated, it is less lethal, with reasonable survival rates in medically treated patients.
For type A dissections treated medically it is approximately 20% within the first 24 hours and 50% by 1 month after presentation. Old standards and new directions. Anesthetic considerations in this patient population are similar to those undergoing AAA repair and both open and endovascular surgical techniques have been used.

Atherosclerosis and systemic hypertension are thought to be the most common causes of aortic dissection initiated by intimal tears. Classically, dissections are labeled acute when clinical symptoms have lasted for 14 days or less and chronic if symptom duration exceeds 2 weeks. Patients with such complications necessitating intervention have a higher mortality of at least 30%.4, Asheesh Kumar MD, Rae M. Allain MD, in Critical Care Secrets (Fifth Edition), 2013.

However, collateral circulation does not account for the low incidence of clinical ischemic syndromes of the spinal cord compared with the cerebral circulation. Iam delighted to see that my predictions were accurate in regard to this effective For untreated acute dissection of the ascending aorta the mortality rate is 1% to 2% per hour after onset. An aortic dissection can be considered chronic after 2 weeks, because mortality tends to level off at that time.

According to the International Registry of Aortic Dissection (IRAD), a worldwide registry of 21 centers with consecutively enrolled patients, the in-hospital mortality for all dissections is 27%. Pathologic examination of dissecting aortic hematomas after surgery or at autopsy may be unable to distinguish whether the abnormalities in the media and intima are primary or secondary. The Stanford classification system simplifies the schema by entry site only, with Stanford type A dissection originating in the ascending aorta and Stanford type B dissection originating in the descending aorta. From 60% to 70% of patients presenting with aortic dissection will have a Stanford type A dissection. Semin Thorac Cardiovasc Surg 5: 11–6, Roberts CS, Roberts WC (1991) Dissection of the aorta associated with congenital malformation of the aortic valve. Despite improvements in surgical, anesthetic, interventional, and medical techniques, even the mortality and morbidity of treated patients remain high. Collateral circulation also determines whether ischemic symptoms result from occlusion of the ostia of the radicular branches. Download full-text PDF. This phenomenon may partly explain how extensive aortic dissections can cause either no symptoms or only transient ones. Even with surgical intervention, the mortality rate for type A dissection may be as high as 10% after 24 hours and nearly 20% 1 month after repair. Joanna Ponińska, ... Zofia T.

Aortic dissection is an aortic syndrome characterized by a tear in the intima that may subsequently be propagated by pulsatile blood flow with development of a false lumen between the dissected layers of the arterial wall.

It may be that two to three times as many patients die of dissections as of ruptured aortic aneurysms; approximately 75% of patients with ruptured aortic aneurysm will reach an emergency department alive, whereas for aortic dissection 40% die immediately. La dissection aiguë de l’aorte thoracique ascendante est une condition pathologique potentiellement catastrophique, exigeant une prise en charge tant diagnostique que thérapeutique urgente. Pain is the most common presenting symptom, occurring in approximately 95% of patients, and is usually described as sudden in onset.2, Acute aortic dissection is highly lethal if not recognized and treated aggressively.

Ischemia of the spinal cord causes predominantly lower motor neuron signs because the gray matter needs more oxygen than the white matter does. Little is known about the frequency of anatomic variations between individuals because these studies have not been repeated recently because of the tedious work involved in dissecting and identifying the various branches. Thoracic aneurysms and diameter of the aorta, especially in patients with genetic disorders, are two of the most important risk factors of aortic dissection; however, only 16% of patients with thoracic aortic dissection have known aneurysms.
Two population-based studies indicated incidences of 2.9 and 3.5 acute aortic dissections per 100,000 person years.2,3 It is seen more often in men, with a ratio of 5:1.
Two population-based studies indicated incidences of 2.9 and 3.5 acute aortic dissections per 100,000 person years. The in-hospital mortality rate is about 59% among medically treated patients with type A aortic dissection.16 Also, the in-hospital mortality rate is about 13% among patients with type B aortic dissections.17 The incidence of aortic dissection has been rising, partly because of the improvement in and availability of diagnostic methods. The causes of death and morbidity attributed to type A aortic dissection included rupture of the ascending aorta causing cardiac tamponade, myocardial ischemia or infarction when the dissection involves the coronary ostia, heart failure caused by acute AR, stroke caused by malperfusion of the aortic arch branch vessels, mesenteric malperfusion causing renal failure or ischemic bowel, or limb ischemia.20 Aortic dissection can also rupture into the right atrium, the right ventricle, or the left atrium causing intracardiac shunting with congestive heart failure.
