Endovascular Management of Chronic Type B Aortic Dissection

Area of Science:

• Cardiology
• Vascular Surgery
• Medical Imaging

Background:

• Acute uncomplicated type B aortic dissection (aTBAD) typically receives non-operative management focused on blood pressure and heart rate control.
• Chronic type B aortic dissection (cTBAD) is defined as dissection persisting beyond 3 months post-diagnosis.
• Monitoring for cTBAD involves regular clinical and imaging follow-up to detect instability, aneurysm formation, or malperfusion.

Purpose of the Study:

• To present and discuss four cases of chronic type B aortic dissection (cTBAD).
• To illustrate the application of thoracic endovascular aortic repair (TEVAR) in managing cTBAD.
• To explore the varying techniques employed during TEVAR for cTBAD.

Main Methods:

• Case series review of four patients diagnosed with cTBAD.
• Application of thoracic endovascular aortic repair (TEVAR) as a treatment modality.
• Analysis of different technical approaches used in TEVAR procedures.

Main Results:

• Successful management of four cTBAD cases using TEVAR.
• Demonstration of diverse TEVAR techniques tailored to individual patient anatomy and pathology.
• Evaluation of dissection stability and potential complications post-TEVAR.

Conclusions:

• Thoracic endovascular aortic repair (TEVAR) is a viable option for managing chronic type B aortic dissection (cTBAD).
• The choice of TEVAR technique should be individualized based on patient-specific factors.
• Further research into optimal TEVAR strategies for cTBAD is warranted.
