Successful Aortic Remodeling Through the Candy-Plug Technique for Chronic Type B Aortic Dissection

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Vascular Medicine

Background:

• Type B aortic dissection can lead to progressive aortic dilation and rupture.
• Endovascular repair is a common treatment, but achieving optimal aortic remodeling remains a challenge.
• The candy-plug technique offers a novel approach to occlude the false lumen in aortic dissection.

Purpose of the Study:

• To evaluate the efficacy of the candy-plug technique using an Excluder aortic extender in achieving aortic remodeling.
• To describe the procedural outcomes and long-term results of this technique in a patient with aortic dissection.

Main Methods:

• A case study of a 46-year-old male patient with acute type B aortic dissection and descending aorta dilation.
• Treatment involved the candy-plug technique with an Excluder aortic extender and an Amplatzer Vascular Plug II.
• Post-procedure imaging (CT scans) were used to assess aortic remodeling and false lumen status.

Main Results:

• The candy-plug technique was technically successful with no complications.
• Significant aortic remodeling was observed at 6 months, including complete false lumen thrombosis.
• The descending aorta diameter reduced from 53 mm to 47 mm, with the extender adopting an elliptical shape.

Conclusions:

• The candy-plug technique with an Excluder aortic extender is an effective method for false lumen occlusion and aortic remodeling in type B aortic dissection.
• Indications include a peripheral entry tear in the descending abdominal aorta and a non-dilated false lumen.
• Further studies are needed to confirm long-term outcomes and optimize technique placement to avoid compromising critical arteries.
