title: Concomitant percutaneous treatment of aortic coarctation and associated intercostal aneurysms: pre-procedural recognition is key.
abstract: Intercostal aneurysms are associated with aortic coarctation. Their aetiology is not well-understood but may be related to intrinsic vascular pathology and altered flow dynamics through the intercostal artery. We present the cases of two patients with coarctation and intercostal aneurysms. The aneurysms were recognised on pre-catheterisation imaging studies and were selectively occluded during the same procedure to treat the coarctation. There were no complications; both the patients have no residual coarctation at the most recent follow-up. Intercostal aneurysms associated with coarctation can have significant consequences including late rupture, paralysis, and even death. These aneurysms are common with an incidence of up to 40% with adult-diagnosed coarctation; one treatment plan is to treat both the coarctation and aneurysm during a single catheterisation. Pre-catheterisation CT or MRI may play a role in this strategy.
