Abstract: Background: article presents a case of 11-month-old baby weighing 6,590, with phenomena of circulatory decompensation, and non-standard hybrid intervention using retroperitoneal open access to the infrarenal aorta - stent implantation with the potential for increasing its diameter as the child grows Materials and methods: the patient underwent examination - echocardiography (Echo-CG), multispiral computed tomography (MSCT), angiography Indication for the operation was the restenosis of the distal aortic anastomosis after the stage-by-stage surgical correction of hypoplastic left heart syndrome (Norwood procedure). This tactic was chosen taking into account the extremely high risk of re-surgery, as well as the impossibility of stent implantation with the potential for increasing the diameter through access to the femoral artery (body weight of the child is Results: good early postoperative period, against the background of disaggregant therapy (aspirin 5 mg/kg per day) and antibiotic therapy In control echocardiography (Echo-CG), the systolic pressure gradient in the stent implantation zone is Conclusion: stenting of restenosis in distal aortic anastomosis using retroperitoneal access can be considered as a surgery of choice in specialized centers.
