Several different classification systems have been used to describe aortic dissections.

Aortic dissection – Wikipedia

Current Guidelines for Treatment”. Other tests that may be used include an aortogram or magnetic resonance angiogram of the aorta. If the pain is pleuritic in nature, it may suggest acute pericarditis caused by bleeding into the pericardial sac. Subscribe to our Newsletter.

While taking a good history from the individual may be strongly suggestive of an aortic dissection, the diagnosis cannot always be made by history and physical signs alone. The mean age at diagnosis is 63 years. Syphilis only potentially causes aortic dissection in its tertiary stage. These images are produced by taking rapid, thin-cut slices of the chest and disecciom, and combining them in the computer to create cross-sectional slices.

In this subset, the incidence in young individuals is increased. Retroperitoneal and pericardial ruptures are both possible.

An acute dissection is one in which the individual presents within disecccion first two weeks. The blood travels through the media, creating a false lumen the true lumen is the normal ddiseccion of blood in the aorta.

A Systematic Review and Meta-analysis”. The reason for surgical repair of type A dissections is that ascending aortic dissections often involve the aortic valve, which, having lost its suspensory support, telescopes down into the aortic root, resulting in aortic incompetence.

Chest trauma leading to aortic aorticz can be divided into two groups based on cause: The risk of dissection in individuals with bicuspid aortic valve is not associated with the degree of stenosis of the valve. A number of comorbid conditions increase the surgical risk of repair of an aortic dissection.

Contrast is injected and the scan performed using a bolus tracking method. It is especially good in the evaluation of AI in the setting of ascending aortic dissection, and to determine whether the ostia origins of the coronary arteries are involved. The Stanford system is used more commonly now, as it is more attuned to the management of the patient. Concern should be increased in those with low blood pressure, neurological problems, and an unequal pulses.

Turner syndrome also increases the risk of aortic dissection, by aortic root dilatation. Retrieved 6 January In an acute dissection, treatment choice depends on its location. A pleural effusion fluid collection in the space between the lungs and the chest wall or diaphragm can be due to either blood from a transient rupture of the aorta or fluid due to an inflammatory reaction around the aorta.

In these cases, the inciting event is thought to be an intramural hematoma caused by bleeding within the media.

Calcium channel blockers can be used in the treatment of aortic dissection, particularly if a contraindication to the use of beta blockers exists. In the image to the right, color flow during ventricular systole suggests that the upper lumen is the true lumen. Each of these tests has pros and cons, and they do not have equal sensitivities and specificities in the diagnosis of aortic dissection.

Pericardial tamponade is the most common cause of death from aortic dissection. People with an aortic dissection often have a history of high blood pressure ; the blood pressure is quite variable at presentation with acute aortic dissection, and tends to be higher in individuals with a distal dissection. Repair may be recommended when greater than 4. D ICD – Establishing the incidence of aortic dissection has been difficult because many cases are only diagnosed after death which may have been attributed to another causeand is often initially misdiagnosed.

It may extend proximally closer to the heart or distally away from the heart or both. Hypertension Hypertensive heart disease Hypertensive emergency Aorttica nephropathy Essential hypertension Secondary hypertension Renovascular hypertension Benign hypertension Pulmonary hypertension Systolic hypertension White coat hypertension. The relative risk of late rupture of an aortic aneurysm is 10 times higher in individuals who have uncontrolled hypertension, compared to individuals with a systolic pressure below mmHg.

Aortic dissection is more common in those with a history of high blood pressurea number of connective tissue diseases that affect blood vessel wall strength such as Marfan syndrome and Ehlers Danlos syndromea bicuspid aortic valveand previous heart surgery.
