Which of the following is a contraindication for AAA repair?

A contraindication for abdominal aortic aneurysm (AAA) repair would include the absence of connective tissue disorders. Connective tissue disorders, such as Marfan syndrome or Ehlers-Danlos syndrome, can predispose patients to vascular complications and may influence the approach to surgical intervention. In patients with these conditions, repair may require specialized techniques or additional considerations due to the elasticity and integrity of their vascular structures.

In contrast, a history of smoking is a risk factor for aneurysm development and progression but not a strict contraindication for repair. Age over 75 can be a factor in the decision-making process, but it is not an absolute contraindication. Many surgeons will consider various risk factors, including overall health, when assessing surgical risk in older patients. Hypertension is common among patients with AAA and can usually be managed perioperatively, making it not a contraindication on its own.

Thus, the absence of connective tissue disorders is particularly significant in determining whether a patient is suitable for AAA repair.
