Abdominal & Thoracoabdominal Aorta
In Situ Laser-Fenestration
Creating precise graft openings to preserve branch arteries.
What it is
In situ laser-fenestration creates precise openings in a stent-graft after it is placed, restoring flow to branch arteries during complex aortic repair when off-the-shelf devices don’t fit the anatomy or there isn’t time to build a custom graft.
When it’s recommended
- Complex or urgent anatomy not suited to a pre-made device
- Need to preserve flow to arch or visceral branches
- Selected endovascular reconstructions
How it’s performed
Every plan is individualized and reviewed by our multidisciplinary aortic team.
The covered stent-graft is deployed across the branch
A laser creates a precise fenestration aligned to the artery
A small covered stent bridges the graft to the branch
Flow and seal are confirmed by imaging
Recovery & follow-up
A minimally invasive recovery with surveillance imaging, individualized to the overall repair.
