Clinical Causes: Chronic high blood pressure (hypertension) Atherosclerosis (hardening of the arteries) Genetic connective tissue disorders like Marfan syndrome or Ehlers-Danlos syndrome Previous heart surgery or traumatic injury Age-related degeneration of the arterial wall Premature aging of blood vessel walls Inflammatory conditions affecting blood vessels

Key Symptoms: Sudden, severe chest or upper back pain, often described as tearing, ripping, or stabbing Pain that may radiate to the neck, jaw, arms, or abdomen Shortness of breath Loss of consciousness or fainting Weakness, paralysis, or numbness in limbs (if blood flow to spinal cord or brain is affected) Difficulty speaking or understanding speech Signs of shock, such as cold, clammy skin, rapid heartbeat, or sweating

Diagnosis Path: Diagnosing an aortic dissection involves a combination of clinical assessment and imaging tests. Common diagnostic methods include: - **Computed tomography (CT) scan**: Rapid, detailed visualization of the aorta - **Magnetic resonance imaging (MRI)**: Provides detailed images without radiation - **Echocardiography**: Especially transthoracic or transesophageal echocardiography, to visualize the heart and aorta - **Aortography**: An invasive imaging technique using contrast dye and X-rays Early diagnosis is vital for effective management and to reduce the risk of serious complications.

Treatment Protocols: Treatment options for an aortic dissection depend on its location, severity, and the patient's overall health. They commonly include: - **Emergency surgery**: Often necessary for dissections involving the ascending aorta or if the dissection is extensive or worsening - **Medical management**: Blood pressure control with medications such as beta-blockers and vasodilators to reduce stress on the aorta - **Monitoring and follow-up**: Regular imaging to track the dissection and prevent further complications In some cases, minimally invasive procedures or endovascular repairs may be suitable, particularly for certain aortic segments. Lifelong surveillance and risk factor management are essential components of ongoing care.
