Stenting of Coarctation of Aorta in Children With Extreme and Very Low Body Weight by Access Through the Right Common Carotid Artery. Description of 2 Clinical Cases

Highlights We present the experience of staged endovascular and surgical treatment of aortic coarctation in children with extremely low and very low body weight using access through the common carotid artery. Absract In neonates with coarctation of the aorta, there are conditions such as extreme prematurity with extremely low birth weight, or severe comorbid conditions in which it is impossible to apply typical methods of defect correction (such as resection of the narrowed area with anastomosis under cardiopulmonary bypass or without it), it is possible to perform endovascular correction as a bridge to further surgical correction after overcoming critical conditions or achieving optimal growth and weight indicators. Balloon valvuloplasty does not show the preservation of favorable results in the long-term period. Stenting with use coronary stents allows for a critical narrowing of the aortic isthmus quite quickly and safely. However, the choose a vascular access for the stenting procedure remains an unresolved issue. This article presents the results of staged treatment with stenting of coarctation of the aorta through the right artery in two premature small children.
