Insights
Thoracic aortic dissection (AD) and intramural hematoma (IMH) are life-threatening aortic emergencies. Thoracic endovascular aortic repair (TEVAR) offers a viable treatment option for both conditions, improving patient outcomes.
Area of Science:
- Cardiovascular Surgery
- Vascular Medicine
- Interventional Radiology
Background:
- Thoracic aortic dissection (AD) and intramural hematoma (IMH) represent critical aortic emergencies.
- Prompt diagnosis and treatment are essential to prevent fatal outcomes.
- IMH is recognized as distinct from classic AD but shares similar emergent characteristics.
Purpose of the Study:
- To review thoracic endovascular aortic repair (TEVAR) as a treatment modality for AD and IMH.
- To detail the indications, imaging techniques, and follow-up protocols for TEVAR in these aortic emergencies.
Main Methods:
- Review of current literature and clinical practices regarding TEVAR for AD and IMH.
- Analysis of imaging modalities used for diagnosis and procedural guidance.
- Examination of follow-up strategies post-TEVAR.
Main Results:
- TEVAR is established as an effective treatment for complicated AD.
- TEVAR is also a viable option for managing complicated IMH.
- Specific indications, imaging requirements, and follow-up schedules are crucial for successful TEVAR outcomes.
Conclusions:
- TEVAR provides a minimally invasive approach for treating thoracic aortic dissection and intramural hematoma.
- Comprehensive pre-procedural imaging and diligent post-procedural follow-up are critical for optimizing TEVAR efficacy.
- TEVAR represents an important advancement in the management of complex aortic emergencies.
Abstract:
Thoracic aortic dissection (AD) is one of the most common aortic emergencies. It can be fatal if not promptly diagnosed and treated. Intramural hematoma (IMH) of the aorta is recognized as distinct from classic (double-barreled) AD. IMH also frequently leads to aortic emergency, which can be fatal unless rapidly diagnosed and treated. Recently, thoracic endovascular aortic repair (TEVAR) has been used for the treatment of complications caused by AD. TEVAR is also a viable option for the treatment of complicated IHM. In this article, we review the details of TEVAR as treatment options for AD and IMH, including the indications for TEVAR, imaging, and follow-up.
