Diagnosis of Aortic Dissection
Aortic dissection is a life-threatening medical emergency that requires prompt diagnosis and treatment. The diagnosis is typically made based on the following:
Clinical Presentation:
Sudden, severe chest pain that may radiate to the back, neck, or arms
Shortness of breath
Nausea and vomiting
Unequal pulses in the arms or legs
Differences in blood pressure between the arms
Physical Examination:
A doctor will listen for an abnormal heart rhythm or a new murmur.
They will check for unequal pulses or differences in blood pressure.
They may find tenderness over the aorta.
Imaging Studies:
Chest X-ray: Can show widening of the mediastinum (the space between the heart and lungs), which can indicate an aortic dissection.
Transthoracic echocardiogram (TTE): An ultrasound test that provides detailed images of the heart and aorta.
Transesophageal echocardiogram (TEE): A more invasive form of echocardiogram that allows for a closer look at the aorta.
Computed tomography (CT) scan: Provides cross-sectional images of the chest and abdomen, which can accurately identify the location and extent of the dissection.
Magnetic resonance imaging (MRI): Another imaging test that can provide detailed images of the aorta.
Other Tests:
Blood tests: To rule out other possible causes of chest pain, such as a heart attack or pulmonary embolism.
Electrocardiogram (ECG): To assess the heart's electrical activity.
Differential Diagnosis:
Aortic dissection should be differentiated from other conditions that can cause similar symptoms, such as:
Myocardial infarction (heart attack), Pulmonary embolism, Acute pulmonary hypertension, and Peptic ulcer disease.
Note: Early diagnosis and treatment are crucial for aortic dissection. If you experience sudden, severe chest pain, seek emergency medical attention immediately.
