P01.006 Aortic aneurysm

Types of Aortic Aneurysms:

Points to Remember:

• Risk Factors:
  • Advancing age
  • Male gender
  • Hypertension
  • Smoking
  • Atherosclerosis
  • Family history of aortic aneurysms
• Clinical Presentation:
  • Often asymptomatic until advanced stages or complications arise.
  • Symptoms may include abdominal or back pain, pulsatile abdominal mass, or symptoms of compression of adjacent structures.
  • Aortic dissection presents with sudden, severe chest or back pain described as tearing or ripping in nature.
• Diagnosis:
  • Abdominal ultrasound: Screening modality for AAA.
  • CT angiography: Gold standard for diagnosing and assessing the extent of aortic aneurysms.
  • Magnetic resonance angiography (MRA): Alternative imaging modality, particularly useful for patients with contraindications to CT.
• Management:
  • Surveillance: Regular monitoring of small asymptomatic aneurysms (<5.5 cm).
  • Surgical intervention: Indicated for symptomatic aneurysms, rapidly expanding aneurysms (>1 cm/year), or those ≥5.5 cm in diameter.
  • Endovascular repair: Minimally invasive procedure involving stent-graft placement, suitable for certain patients with AAA or TAA.
• Complications:
  • Rupture: Life-threatening complication associated with high mortality rates.
  • Aortic dissection: Emergent condition requiring immediate intervention to prevent catastrophic outcomes.
  • Compression of adjacent structures: This can lead to symptoms such as dysphagia, hoarseness, or leg ischemia depending on the location of the aneurysm.

Key Takeaways:

• Aortic aneurysms pose significant risks, particularly if left untreated or undetected.
• Early recognition, risk factor modification, and appropriate management are essential to prevent complications and improve patient outcomes.
