Insights
Intercostal aneurysms frequently accompany aortic coarctation. Treating both conditions during a single catheterization procedure is a safe and effective strategy, preventing serious complications.
Area of Science:
- Cardiovascular Medicine
- Interventional Cardiology
- Vascular Surgery
Background:
- Intercostal aneurysms are linked to aortic coarctation, though their cause is unclear, possibly involving vascular disease and abnormal blood flow.
- Aortic coarctation is a congenital heart defect causing narrowing of the aorta, often diagnosed in adulthood.
Observation:
- Two patients with coarctation and intercostal aneurysms underwent simultaneous treatment.
- Aneurysms were identified via pre-catheterization imaging and occluded during the coarctation repair procedure.
Findings:
- The combined catheterization procedure for coarctation and intercostal aneurysms was successful with no complications.
- Both patients showed no residual coarctation at follow-up, indicating successful treatment.
Implications:
- Intercostal aneurysms associated with coarctation pose risks of rupture, paralysis, and death.
- Early identification and endovascular occlusion of these aneurysms during coarctation repair offer a viable treatment approach.
- Advanced imaging like CT and MRI can aid in planning this combined therapeutic strategy.
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.
