Diagnosis and Management of Thoracic Aortic Disease

Area of Science:

• Cardiovascular Medicine
• Vascular Surgery
• Diagnostic Imaging

Background:

• Thoracic aortic aneurysms (TAAs) are frequently asymptomatic, detected incidentally during imaging for other conditions.
• Management of small TAAs involves antihypertensive therapy and surveillance via echocardiography, CTA, or MRA.
• Repair decisions are based on rupture risk, with lower thresholds for genetic aortopathies.

Purpose of the Study:

• To outline the diagnostic and management strategies for thoracic aortic aneurysms and acute aortic syndromes.
• To differentiate the clinical presentation and treatment of aneurysms versus acute aortic syndromes.
• To emphasize the importance of follow-up care after treatment.

Main Methods:

• Review of current clinical practices for TAA and acute aortic syndrome management.
• Discussion of imaging modalities (echocardiography, CTA, MRA) for surveillance.
• Analysis of surgical and endovascular treatment approaches based on aneurysm location and etiology.

Main Results:

• TAAs are typically asymptomatic; management is conservative for small aneurysms and surgical for larger ones or those at high risk of rupture.
• Acute aortic syndromes present with symptoms and require timely intervention, with surgery for ascending aorta and endovascular repair for descending aorta.
• Successful treatment of acute aortic syndromes leads to favorable prognosis with ongoing medical management and surveillance.

Conclusions:

• Effective management of thoracic aortic pathology requires accurate diagnosis, risk stratification, and tailored treatment strategies.
• Prompt intervention for acute aortic syndromes is critical for favorable outcomes.
• Long-term follow-up, including medical management and surveillance imaging, is essential after treatment for both aneurysms and acute aortic syndromes.
