Interventional techniques in the treatment of aortic dissection

Area of Science:

• Cardiovascular Surgery
• Interventional Radiology
• Medical Imaging

Background:

• Acute aortic dissection is a life-threatening cardiovascular emergency.
• Ascending aortic dissection typically requires immediate surgical repair.
• Treatment for type B aortic dissection remains controversial, with evolving therapeutic strategies.

Purpose of the Study:

• To review the role of endovascular stent-graft implantation in treating type B aortic dissection.
• To highlight the importance of various imaging modalities in the management of type B aortic dissection.
• To discuss the technical feasibility, safety, and potential future indications for endovascular repair.

Main Methods:

• Review of current literature and clinical reports on endovascular treatment for type B aortic dissection.
• Emphasis on the utility of computed tomography (CT), magnetic resonance imaging (MRI), angiography, and transesophageal echocardiography.
• Discussion of procedural monitoring and postoperative follow-up imaging.

Main Results:

• Endovascular stent-graft implantation has emerged as a significant treatment option for type B aortic dissection.
• Imaging techniques are essential for patient selection, procedural guidance, and assessing outcomes.
• Potential risks include endoleaks, which can compromise repair and increase rupture risk.

Conclusions:

• Endovascular repair offers a feasible and safe alternative for type B aortic dissection.
• Advanced imaging plays a critical role throughout the entire treatment pathway.
• Ongoing trials may expand indications to include uncomplicated type B aortic dissections.
