EVAR and TEVAR treat different parts of the aorta
TEVAR refers to thoracic endovascular aortic repair, while EVAR is commonly used for endovascular repair of abdominal aortic disease. DHZC describes endovascular stent-graft treatment for appropriate aneurysms and notes that open surgery remains necessary when anatomy or underlying disease makes an endovascular approach unsuitable.
CT angiography is central to planning
Endovascular repair depends on detailed measurements of the aorta and access vessels. A meaningful second opinion therefore requires the original CT angiography images rather than only a written radiology report.
- Current CT angiography in DICOM format when requested
- Aneurysm diameter and exact segment involved
- Relationship to renal, visceral or arch branch vessels
- Previous aortic operations or stent-grafts
- Renal function and contrast-related considerations
- History of connective-tissue disease or genetic aortopathy
Open surgery may still be the safer or more durable option
A large or anatomically complex aneurysm, inadequate landing zones, infection, some connective-tissue disorders or other technical factors can make open repair preferable. The treatment question is therefore not simply 'Can a stent be inserted?' but which strategy provides an acceptable balance of immediate risk, durability and future reinterventions.
Complex aneurysms may require advanced endovascular techniques
The German Aortic Center Hamburg describes fenestrated and branched stent-graft techniques for selected thoraco-abdominal and post-dissection aneurysms. These cases require highly detailed planning because major branch vessels may need to remain perfused through custom or complex endovascular configurations.
Follow-up imaging is part of the treatment
An endovascular repair is not finished when the stent graft is implanted. Surveillance imaging is needed to evaluate graft position, aneurysm sac behavior, endoleaks and other late complications. International patients should agree on a follow-up schedule and confirm where imaging will be performed after returning home.
