Abstract
Male adolescent fourteen years old with Coarctation diagnosed at the age of eleven. He underwent cardiac catheterization with percutaneous balloon dilation and stent implantation. The immediate result was satisfactory but three years later a transverse fracture of the stent was detected on cardiac Magnetic Resonance Imaging with findings of moderate restenosis. This complication was treated with percutaneous implantation of a covered stent. The case of this adolescent is interesting because late fracture of aortic stent is a rare complication and covered stent implantation is a sufficient treatment whether or not there is recoarctation.
Highlights
Coarctation angioplasty with stent implantation in children older than six, adolescents and adults is adequate treatment of native coarctation with immediate and long-term results comparable with surgical repair [1,2]
Fracture of the stent is a rare complication and occurs typically when implanting it, automatically with time, or at the effort of redilating it in order to adapt the stent to the physical growth of the patient [3]. It can be considered ‘nightmare’ of interventional pediatric cardiology [4]. This complication can be treated by implanting covered stent which completely covers the inner lumen of the original one, preventing this way possible erosion of the inner aortic wall by the sharp ends of the fractured stent [5]
We describe the case of a fourteen year old adolescent who was found to have coarctation at the age of eleven
Summary
Late Transverse Aortic Stent Fracture in Adolescent with Coarctation of the Aorta. Treatment of the Complication with Covered Stent Insertion with in the Fractured Stent.
