Diagnosing diseases of the aorta before surgery is a critical step in cardiac care, because the aorta is the main blood vessel in the body. Any treatment decision depends heavily on accurate identification of the type, severity, and location of the disease.
Aortic diseases include conditions such as:
- Aortic aneurysm
- Aortic dissection
- Other structural or degenerative diseases of the aortic wall
In this article, we explain how these conditions are diagnosed before deciding on surgical intervention.
1. Clinical Assessment
The diagnostic process always begins with a detailed clinical evaluation by the physician, including:
- Medical history
- Presenting symptoms
- Blood pressure measurement
- General physical examination
Common warning symptoms may include:
- Severe chest or back pain
- Sudden tearing or ripping pain (especially in dissection)
- Shortness of breath
- Dizziness or fainting in severe cases
However, it is important to note that many cases of aortic aneurysm can be completely asymptomatic and discovered incidentally.
2. Transthoracic Echocardiography (TTE)
Echocardiography is usually the first imaging test and helps evaluate:
- The aortic root (proximal aorta)
- Aortic valve function
- Cardiac chamber size and function
However, its limitation is that it does not provide full visualization of the entire aorta, so further imaging is often required.
3. CT Angiography (CTA) – The Gold Standard
CT angiography is considered one of the most important and accurate diagnostic tools for aortic diseases.
It provides detailed information about:
- Aortic diameter and size
- Presence of aneurysm or dissection
- Extent of disease in the chest or abdomen
- Presence of thrombus inside an aneurysm
- Relationship with surrounding organs and structures
Why is CTA so important?
Because it allows surgeons to:
- Define the exact surgical plan
- Choose the appropriate intervention strategy
- Accurately assess surgical risk
4. Magnetic Resonance Imaging (MRI / MRA)
MRI is used in selected cases, especially when:
- CT contrast cannot be used
- Long-term follow-up is required
It provides detailed information about:
- Blood flow dynamics within the aorta
- Aortic wall structure
- Progression of disease over time
5. Cardiac Catheterization (When Needed)
In certain cases—especially when coronary artery disease is suspected—cardiac catheterization may be performed to evaluate:
- Coronary artery status
- Relationship between aortic disease and the heart
- Hemodynamic pressure measurements
6. Transesophageal Echocardiography (TEE)
TEE is a more advanced form of echocardiography used in urgent or highly detailed evaluations.
It is particularly useful because:
- It provides clearer images than standard echocardiography
- It offers excellent visualization of the ascending aorta
- It is highly valuable in suspected acute aortic dissection
7. Laboratory Investigations
In addition to imaging, laboratory tests are performed to prepare the patient for possible surgery, including:
- Complete blood count (CBC)
- Kidney function tests
- Liver function tests
- Coagulation profile
- Electrolyte levels
These tests help assess overall surgical readiness and risk.
How Is the Surgical Decision Made?
After collecting all diagnostic data, the decision for surgery is based on:
1. Size and Severity of the Disease
Larger aneurysms or severe dissections often require urgent intervention.
2. Rate of Progression
Whether the condition is stable or rapidly worsening.
3. Symptoms
Presence of pain, organ involvement, or other complications.
4. Overall Patient Condition
Including:
- Age
- Chronic diseases
- Heart function
Why Is Accurate Diagnosis So Important?
Incorrect or incomplete evaluation may lead to:
- Delayed necessary surgery
- Unnecessary surgical intervention
- Increased risk of life-threatening complications
Therefore, diagnosis is always based on multiple complementary investigations rather than a single test.
Conclusion
Diagnosis of aortic diseases before surgery relies on a structured approach that includes:
- Clinical evaluation
- Transthoracic echocardiography
- CT angiography (key diagnostic tool)
- MRI when needed
- Cardiac catheterization in selected cases
- Laboratory tests
The main goal is to determine:
the type of disease, its severity, extent, and the safest timing for surgery.
