Summary
This study presents a novel electrocautery technique for aortic fenestration during thoracic endovascular repair. This method effectively eliminates type Ib false lumen perfusion in chronic distal thoracic dissections.
Area of Science:
- Vascular Surgery
- Endovascular Interventions
- Aortic Dissection
Background:
- Chronic distal thoracic dissections pose challenges for endovascular repair.
- Type Ib false lumen perfusion is a common complication after thoracic endovascular repair.
Purpose of the Study:
- To describe a novel technique for aortic fenestration to eliminate type Ib false lumen perfusion.
- To present a controlled method for creating fenestrations in the dissection septum.
Main Methods:
- A novel technique using electrocautery delivered via a wire tip to fenestrate the dissection septum.
- Controlled cutting of the septum using electrocautery over an uninsulated wire segment.
Main Results:
- The described electrocautery method allows for deliberate fenestration of the dissection flap.
- This technique aims to create a seal zone proximal to the visceral vessels.
Conclusions:
- Electrocautery offers a controlled and precise approach for aortic fenestration in endovascular repair of distal thoracic dissections.
- This technique may improve outcomes by eliminating type Ib false lumen perfusion.
