What is a contraindication for using endografts in abdominal aortic aneurysm?

Using endografts for abdominal aortic aneurysm (AAA) repair has specific contraindications that must be considered to ensure patient safety and the effectiveness of the intervention. In the context of this question, Marfan syndrome is a known contraindication for the use of endografts.

Marfan syndrome is a genetic disorder that affects connective tissue, leading to various cardiovascular issues, including aortic dilation and dissection. Patients with Marfan syndrome often have an abnormal aorta that may be too weak or have an altered anatomical structure, making the deployment of endografts particularly risky. The use of endografts in these patients could lead to complications such as graft failure or further complications related to the underlying connective tissue disorder.

In contrast, other options such as AAA with a diameter of 5 cm or greater, inflammatory AAA, and contained-rupture AAA are not outright contraindications. For instance, a AAA of this size often warrants intervention due to the increased risk of rupture, and inflammatory AAAs can sometimes be treated with careful planning and assessment. Contained-rupture AAAs, while critical and requiring prompt attention, may still be managed with endovascular techniques if appropriate anatomical conditions are met. Therefore, Marfan syndrome stands out as a true
