Aortic aneurysm is a localized dilation of the aorta that enlarges over time and risks rupture, while aortic dissection is a tear in the wall that separates its layers. Both demand precise imaging-based surveillance and, when thresholds are crossed, definitive repair.
Clinical context
This article examines advances in fenestrated and branched endografts for complex aortic aneurysm repair within the wider field of aortic aneurysm & dissection repair. Endovascular aneurysm repair excludes the sac with a covered stent graft delivered through the femoral arteries, avoiding open thoracoabdominal surgery in suitable anatomy. Fenestrated and branched designs extend endovascular repair to aneurysms involving visceral and renal branches.
Key considerations
- Endovascular aneurysm repair excludes the sac with a covered stent graft delivered through the femoral arteries, avoiding open thoracoabdominal surgery in suitable anatomy.
- Fenestrated and branched designs extend endovascular repair to aneurysms involving visceral and renal branches.
- The multilayer flow modulator concept redirects flow to promote laminar patterns and sac thrombosis while preserving flow through branch vessels.
- Accurate sizing from cross-sectional imaging and adequate sealing zones are decisive for durable exclusion and freedom from endoleak.
Diagnosis and evaluation
Careful patient selection and imaging-based evaluation underpin good outcomes in this area. Terminology that frequently arises includes endovascular aneurysm repair, endoleak, sealing zone, branch vessel. A structured assessment helps match the individual patient to the most appropriate treatment pathway.
Treatment approaches and technologies
The multilayer flow modulator concept redirects flow to promote laminar patterns and sac thrombosis while preserving flow through branch vessels. A range of device technologies supports contemporary practice in aortic aneurysm & dissection repair.
