मार्फान सिन्द्रम is noted in 5-9% of individuals who suffer from aortic dissection. In this subset, there is an increased incidence in young individuals. Individuals with Marfan syndrome tend to have aneurysms of the aorta and are more prone to proximal dissections of the aorta.
Chest trauma leading to aortic dissection can be divided into two groups based on etiology: blunt chest trauma (commonly seen in car accidents) and iatrogenic. Iatrogenic causes include trauma during cardiac catheterization or due to an intra-aortic balloon pump.
Aortic dissection may be a late sequalae of cardiac surgery. 18% of individuals who present with an acute aortic dissection have a history of open heart surgery. Individuals who have undergone aortic valve replacement for aortic insufficiency are at particularly high risk. This is because aortic insufficiency causes increased blood flow in the ascending aorta. This can cause dilatation and weakening of the walls of the ascending aorta.
About 96% of individuals with aortic dissection present with severe pain that had a sudden onset. It may be described as tearing in nature, or stabbing or sharp in character. 17% of individuals will feel the pain migrate as the dissection extends down the aorta. The location of pain is associated with the location of the dissection. Anterior chest pain is associated with dissections involving the ascending aorta, while intrascapular (back) pain is associated with descending aortic dissections. If the pain is pleuritic in nature, it may suggest acute pericarditis due to hemorrhage into the pericardial sac.
While the pain may be confused with the pain of a myocardial infarction (heart attack), aortic dissection is usually not associated with the other signs that suggest myocardial infarction, including heart failure, and ECG changes. Also, individuals suffering from an aortic dissection usually do not present with diaphoresis (profuse sweating).
Individuals with aortic dissection who do not present with pain have chronic dissection.
Less common symptoms that may be seen in the setting of aortic dissection include congestive heart failure (7%), syncope (9%), cerebrovascular accident (3-6%), ischemic peripheral neuropathy, paraplegia, cardiac arrest, and sudden death. If the individual had a syncopal episode, about half the time it is due to hemorrhage into the pericardium leading to pericardial tamponade.
If the aortic dissection involves the abdominal aorta, compromise of the branches of the abdominal aorta are possible. In abdominal aortic dissections, compromise of one or both renal arteries occurs in 5-8% of cases, while mesenteric ischemia (ischemia of the large intestines) occurs 3-5% of the time.
ब्लड प्रेसर भिन्नता[सम्पादन]
While many patients with an aortic dissection have a history of hypertension, the blood pressure is quite variable at presentation with acute aortic dissection, and tends to be higher in individuals with a distal dissection. In individuals with a proximal aortic dissection, 36% present with hypertension, while 25% present with hypotension. In those that present with distal aortic dissections, 70% present with hypertension while 4% present with hypotension.
Severe hypotension at presentation is a grave prognostic indicator. It is usually associated with pericardial tamponade, severe aortic insufficiency, or rupture of the aorta. Accurate measurement of the blood pressure is important. Pseudohypotension (falsely low blood pressure measurement) may occur due to involvement of the brachiocephalic artery (supplying the right arm) or the left subclavian artery (supplying the left arm).
Aortic insufficiency (AI) occurs in 1/2 to 2/3 of ascending aortic dissections, and the murmur of aortic insufficiency is audible in about 32% of proximal dissections. The intensity (loudness) of the murmur is dependent on the blood pressure and may be inaudible in the event of hypotension.
There are multiple etiologies for AI in the setting of ascending aortic dissection. The dissection may dilate the annulus of the aortic valve, so that the leaflets of the valve cannot coapt. Another mechanism is that the dissection may extend into the aortic root and detach the aortic valve leaflets. The third mechanism is that if there was an extensive intimal tear, the intimal flap may prolapse into the LV outflow tract, causing intimal intussusception into the aortic valve preventing proper valve closure.
Myocardial infarction (heart attack) occurs in 1-2% of aortic dissections. The etiology of the infarction is involvement of the coronary arteries (the arteries that supply the heart) in the dissection. The right coronary artery is involved more commonly than the left coronary artery. If the myocardial infarction is treated with thrombolytic therapy, the mortality increases to over 70%, mostly due to hemorrhage into the pericardial sac causing pericardial tamponade.
Because aortic dissection may present to the emergency room physician similar to a myocardial infarction, the physician must be careful to make the proper diagnosis prior to initiating treatment for myocardial infarction, since the treatment regimen for myocardial infarction can be lethal to an individual presenting with aortic dissection.
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. If a pleural effusion were to develop due to an aortic dissection, it is more commonly in the left hemithorax rather than the right hemithorax.
Because of the varying symptoms and signs of aortic dissection depending on the initial intimal tear and the extent of the dissection, the proper diagnosis is sometimes difficult to make.
In an individual with chest pain radiating to the back, the differentials to consider include:
- Aortic dissection
- Myocardial infarction
- Acute aortic insufficiency
- Non-dissecting aortic aneurysm
- Musculoskeletal pain
- Mediastinal tumors
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. Often the diagnosis is made by visualization of the intimal flap on a diagnositic imaging test. Common tests used to diagnose an aortic dissection include a CAT scan of the chest with iodinated contrast material and a trans-esophageal echocardiogram. Other tests that may be used include an aortogram or magnetic resonance angiogram (MRA) of the aorta. Each of these test have varying pros and cons and they do not have equal sensitivities and specificities in the diagnosis of aortic dissection.
In general, the imaging technique chosen is based on the pre-test likelihood of the diagnosis, availability of the testing modality, patient stability, and the sensitivity and specificity of the test.

Widening of the mediastinum on an x-ray of the chest has moderate sensitivity (67%) in the setting of an ascending aortic dissection. However, it has low specificity, as many other conditions can cause a widening of the mediastinum on chest x-ray.
The calcium sign is a finding on chest x-ray that suggests aortic dissection. It is the separation of the intimal calcification from the outer aortic soft tissue border by 10 mm.
Pleural effusions may be seen on chest x-ray. They are more commonly seen in descending aortic dissections. If seen, they are typically in the left hemithorax.
Another findings are obliteration of the aortic knob, depression of the left mainstem bronchus, loss of the paratracheal stripe, and tracheal deviation.
About 12%-20% of individuals presenting with an aortic dissection have a "normal" chest x-ray.

There are no specific electrocardiographic findings associated with aortic dissection. About 1/3 of the time, the ECG will show signs of left ventricular hypertrophy, which is due to the long-standing hypertension seen in these individuals. Another 1/3 of the time the ECG would be considered "normal". If the ECG suggests cardiac ischemia in the setting of aortic dissection, involvement of the coronary arteries should be suspected.
While there are currently no blood tests that can accurately diagnose aortic dissection, research has been performed into the serial measurement of monoclonal antibodies to smooth muscle myosin heavy chains that appears to be both sensitive and specific for aortic dissection. The sensitivity of this test is about 90% and the specificity is 97% within the first 12 hours of the beginning of the dissection, and this assay can accurately differentiate myocardial infarction from aortic dissection. This test is not currently available for the diagnosis of aortic dissection in the clinical setting.
The transesophageal echocardiogram (TEE) is a relatively good test in the diagnosis of aortic dissection, with a sensitivity of up to 98% and a specificity of up to 97%. It is a relatively non-invasive test, requiring the individual to swallow the echocardiography probe. 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. While many institutions give sedation during transesophageal echocardiography for added patient-comfort, it can be performed in cooperative individuals without the use of sedation. Disadvantages of the TEE include the inability to visualize the distal ascending aorta (the beginning of the aortic arch), and the descending abdominal aorta that lies below the stomach. A TEE may be technically difficult to perform in individuals with esophageal strictures or varices.
An aortogram involves placement of a catheter in the aorta and injection of contrast material while taking x-rays of the aorta. The procedure is known as aortography. The diagnosis of aortic dissection can be made by visualization of the intimal flap and flow of contrast material in both the true lumen and the false lumen.
The aortogram was previously considered the gold standard test for the diagnosis of aortic dissection, with a sensitivity of up to 88% and a specificity of about 94%. It is especially poor in the diagnosis of cases where the dissection is due to hemorrhage within the media without any initiating intimal tear.
The advantage of the aortogram in the diagnosis of aortic dissection is that it can delineate the extent of involvement of the aorta and branch vessels and can diagnose aortic insufficiency.
The disadvantages of the aortogram are that it is an invasive procedure and it requires the use of iodinated contrast material.

Computed tomography angiography is a fast non-invasive test that will give an accurate three-dimensional view of the aorta. These images are produced by taking rapid thin cut slices of the chest and abdomen, and combining them in the computer to create cross-sectional slices. In order to delineate the aorta to the accuracy necessary to make the proper diagnosis, an iodinated contrast material is injected into a peripheral vein. Contrast is injected and the scan performed using a Bolus Tracking method. This is a type of scan timed to an injection, in order to capture the contrast as it enters the aorta. The scan will then follow the contrast as it flows though the vessel.
It has a sensitivity of 96 - 100% and a specificity of 96 to 100%. Disadvantages include the need for iodinated contrast material and the inability to diagnose the site of the intimal tear.

Magnetic resonance imaging (MRI) is currently the gold standard test for the detection and assessment of aortic dissection, with a sensitivity of 98% and a specificity of 98%. An MRI examination of the aorta will produce a three-dimensional reconstruction of the aorta, allowing the physician to determine the location of the intimal tear, the involvement of branch vessels, and locate any secondary tears. It is a non-invasive test, does not require the use of iodinated contrast material, and can detect and quantitate the degree of aortic insufficiency.
The disadvantage of the MRI scan in the face of aortic dissection is that it has limited availability and is often located only in the larger hospitals, and the scan is relatively time consuming. Due to the high intensity of the magnetic waves used during MRI, an MRI scan is contraindicated in individuals with metallic implants. In addition, many individuals experience claustrophobia while in the MRI scanning tube.

The risk of death is high in untreated aortic dissection. While the risk is highest in the first 24 hours of the event, those that survive the initial event still have an elevated mortality compared to age- and sex-matched controls.
First Aid and Pre-Hospital Life Support[सम्पादन]
It is unlikely that a lay-person will recognize this condition. Call for help and arrange for immediate transport via emergency medical services to advanced medical care. In wilderness first aid, immediate evacuation is imperative, by MEDEVAC to an advanced medical facility if available.
Transport immediately to a facility capable of emergency cardiac surgery such as a trauma center is suggested, not a community hospital without a surgical service. Supportive care including pain and blood pressure control should be provided en route to the medical center.
For Basic Life Support Providers (EMT-B or equivalent): Treat for shock by placing the patient in a modified Trendelenburg position and administering oxygen therapy. Despite chest pain, do not administer nitrates.
For Advanced Life Support Providers (EMT-I or EMT-P): Initiate the above BLS steps. Apply cardiac monitoring and establish intravenous therapy early. Titrate fluid to blood pressure, but do not use vasopressors. Record a diagnostic electrocardiogram to distinguish between aortic dissection and acute myocardial infarction. Do not administer thrombolytics. Analgesia should be accomplished with regard to the vasodilative effects of opioid analgesics such as morphine, fentanyl, and nalbuphine and should not be provided to a patient in decompensated shock.
The risk of death due to aortic dissection is highest in the first few hours after the dissection begins, and decreases afterwards. Because of this, the therapeutic strategies differ for treatment of an acute dissection compared to a chronic dissection. An acute dissection is one in which the individual presents within the first two weeks. If the individual has managed to survive this window period, his prognosis is improved. About 66% of all dissections present in the acute phase.
In all individuals with aortic dissections, medication should be used to control high blood pressure, if present.
In the case of an acute dissection, once diagnosis has been confirmed, the choice of treatment depends on the location of the dissection. For ascending aortic dissection, surgical management is superior to medical management. On the other hand, in the case of an uncomplicated distal aortic dissections (including abdominal aortic dissections), medical management is preferred over surgical treatment 
Individuals who present two weeks after the onset of the dissection are said to have chronic aortic dissections. These individuals have been self-selected as survivors of the acute episode, and can be treated with medical therapy as long as they are stable.
Medical management is appropriate in individuals with an uncomplicated distal dissection, a stable dissection isolated to the aortic arch, and stable chronic dissections. Patient selection for medical management is very important. Stable individuals who present with an acute distal dissection (typically treated with medical management) still have an 8 percent 30 day mortality.
VIDEO - What is New in the Treatment of Type B Aortic Dissection?, Girma Tefera, MD, speaks at the University of Wisconsin School of Medicine and Public Health.
The prime consideration in the medical management of aortic dissection is strict blood pressure control. The target blood pressure should be a mean arterial pressure (MAP) of 60 to 75 mmHg. Another factor is to reduce the shear-force dP/dt (force of ejection of blood from the left ventricle).
To reduce the shear stress, a vasodilator such as sodium nitroprusside should be used with a beta blocker, such as esmolol, propranolol, or labetalol. The alpha-blocking properties of labetalol make it especially attractive in this situation.
Calcium channel blockers can be used in the treatment of aortic dissection, particularly if there is a contraindication to the use of beta blockers. The calcium channel blockers typically used are verapamil and diltiazem, because of their combined vasodilator and negative inotropic effects.
If the individual has refractory hypertension (persistent hypertension on the maximum doses of three different classes of antihypertensive agents), involvement of the renal arteries in the aortic dissection plane should be considered.
Indications for the surgical treatment of aortic dissection include an acute proximal aortic dissection and an acute distal aortic dissection with one or more complications. Complications include compromise of a vital organ, rupture or impending rupture of the aorta, retrograde dissection into the ascending aorta, and a history of Marfan's syndrome or Ehlers-Danlos Syndrome.
The objective in the surgical management of aortic dissection is to resect (remove) the most severely damaged segments of the aorta, and to obliterate the entry of blood into the false lumen (both at the initial intimal tear and any secondary tears along the vessel). While excision of the intimal tear may be performed, it does not significantly change mortality.
Some methods of repair are:
- Replacement of the damaged section with a tube graft (often made of dacron) when there is no damage to the aortic valve.
- Bentall procedure - Replacement of the damaged section of aorta and replacement of the aortic valve.
- David procedure - Replacement of the damaged section of aorta and reimplantation of the aortic valve.
- Insertion of a stent, combined with on-going medical management
A number of comorbid conditions increase the surgical risk of repair of an aortic dissection. These include:
- Prolonged pre-op evaluation (increased length of time prior to surgery)
- Advanced age
- Comorbid disease states (e.g.: coronary artery disease)
- Aneurysm leakage
- Cardiac tamponade
- Past history of myocardial infarction or CVA
- History of renal failure (either acute or chronic renal failure)
Long term follow-up[सम्पादन]
The long term follow-up in individuals who survive aortic dissection involves strict blood pressure control. 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 130 mmHg.
The risk of death is highest in the first two years after the acute event, and individuals should be followed closely during this time period. 29% of late deaths following surgery are due to rupture of either the dissecting aneurysm or another aneurysm. In addition, there is a 17% to 25% incidence of new aneurysm formation. This is typically due to dilatation of the residual false lumen. These new aneurysms are more likely to rupture, due to their thinner walls.
Serial imaging of the aorta is suggested, with MRI being the preferred imaging technique.
