Ten-Year Experience in the Treatment of Coarctation of the Aorta through Endovascular Stenting in Patients of Different Age Groups

The aim. To analyze the 10-year experience in aortic coarctation endovascular stenting in patients of different age groups. Materials and methods. Examination and endovascular treatment of 194 patients aged 3 days to 60 years with coarctation of the aorta (CoA) with different anatomical and morphological variants was performed. According to the age criterion, the examined patients were divided into 4 study groups. The first group consisted of 84 patients (43.3%) over 25 years of age, group 2 included 33 patients (17.0%) aged 19 to 25 years, group 3 included 71 patients (36.6%) aged 5 to 18 years, and group 4 included 6 patients (3.1%) under 1 year of age. Results and discussion. We presented the clinical features of different anatomical and morphological variants of CoA. Endovascular treatment of CoA with stenting is considered the best method for adolescents and adults, due to the lower risk of aneurysm formation compared to balloon angioplasty. We were able to successfully reduce the invasive pressure gradient in patients of different ages and to establish the dependence of complication rate on the stent type used. The most common complications were aneurysm formation (2.1%) and stent migration (2.1%). Complications occurred more often in cases of uncovered stents compared to stent grafts (5.3% and 2.1%, respectively, p
