Abstract

Introduction. Coarctation of the aorta (CoA) is a congenital narrowing of the aorta at the aortic isthmus. Computed tomography angiography (CTA) plays a major role in the imaging of aortic pathologies in children. As a non-invasive method, CTA combined with echocardiography is increasingly used for precise evaluation of cardiovascular pathologies. The aim of the study was to evaluate the use of CTA in children with ambiguous echocardiographic diagnosis of CoA or in patients before planned surgical repair of an aortic arch defect, and to evaluate the agreement between measurements of the aortic dimensions by CTA and echocardiography.

Material and methods. We retrospectively evaluated CTA studies performed in 37 children with suspected CoA and compared aortic diameter measurements by CTA and echocardiography. In all patients, the effective dose was estimated using CTA protocol data.

Results. Based on CTA findings, CoA was diagnosed in 26 children, including 5 children with simple CoA, while 21 children had complex CoA with other coexisting anomalies. A number of additional pathologies were identified when evaluating other chest structures. Statistical analysis showed the agreement of aortic diameter measurements by the two imaging methods. The mean effective dose was 7.5 mSv.

Conclusions. CTA allows precise imaging of aortic pathology in children and is an important diagnostic tool. Echocardiography remains the primary tool for imaging of CoA but has some limitations, particularly in older patients. Indications for CTA should be carefully considered due to the associated radiation exposure.
