Introduction: Our objective is to describe the rate of intracranial aneurysm (ICA) detection by MRI/MRA/CTA in patients with a history of coarctation of the aorta. Hypothesis: A 10% prevalence of ICAs in patients with coarctation of the aorta has been described in a few small studies. This has led to a recommendation to screen all patients with a history of coarctation for ICA with MRA or CTA although no age for this screening is specified. We hypothesize that, with earlier detection and coarctation intervention, the rate of ICA is lower and screening brain imaging may only be warranted in older patients or patients with certain risk factors. Methods: We retrospectively reviewed charts of patients with coarctation of the aorta who had undergone MRI/MRA/CTA imaging ages 13 years and older from the years 2000 to 2018. Results: We identified a cohort of 102 patients and there were no reported ICAs. The median age of coarctation repair was 4.4 months (range 2 days-47 years) and the initial repair was primarily surgical (90.2%). There were 35 (34.3%) patients with recurrent coarctation requiring re-intervention. One patient had CAD, 11 patients were smokers, 4 had a history of DM and 41 (40.2%) had history of HTN following coarctation repair. Imaging modalities included CTA (13.7%), MRI (41.2%) and MRA (46.1%) with 52.9% of those studies being performed for history of coarctation and the remainder performed for neurologic symptoms. The median age of CTA was 33.3 years, of MRI was 22.4 years and of MRA was 25 years. Conclusions: Patients with a history of coarctation of the aorta have been consistently reported to have a 10% risk for ICA, however we have not documented any ICAs by MRI/MRA/CTA in this reviewed patient population. We feel this may reflect the varying age at which patients undergo these imaging studies as well as earlier detection and repair of coarctation. These results suggest that the rate of ICA may be lower than previously reported and that the age of screening should be more clearly described. [ABSTRACT FROM AUTHOR]
