Coil embolization of persistent false lumen after type A dissection repair

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology
• Aortic Disease Management

Background:

• Management of residual type A aortic dissection after prior repair remains challenging.
• Progressive enlargement of the aorta and persistent false lumen flow are known complications.
• Endovascular techniques are increasingly explored for complex aortic pathologies.

Observation:

• A 44-year-old male with a history of type A aortic dissection repair presented with enlarging residual aorta.
• Contrast-enhanced computed tomography revealed persistent false lumen flow from the distal suture line.
• Direct access to the false lumen was achieved via redo sternotomy.

Findings:

• An Amplatzer plug was deployed in the false lumen's narrow neck.
• Interlocking coils were placed proximal to the plug.
• This combined approach successfully thrombosed the false lumen, addressing aortic enlargement.

Implications:

• This technique offers a potential minimally invasive solution for managing false lumen patency after aortic dissection repair.
• Successful false lumen thrombosis may prevent further aortic expansion and associated risks.
• Further research is warranted to evaluate long-term outcomes and applicability in diverse patient populations.
