Clinical application of Cheatham-Platinum covered stent in treatment of aortic coarctation

Abstract

Objective To evaluate the clinical safety and efficacy of Cheatham-Platinum(CP)covered stent in treatment of aortic coarctation.Methods The therapeutic efficacy was retrospectively analyzed in 15 patients with aortic coarctation who were treated by BIB balloon dilation and CP covered stent implantation.Results All patients were well recovered,the stent did not appear displaced,folded,aorta dissection and rupture.The pressure difference was 5-10 mm Hg(1 mm Hg=0.133 kPa)between proximal part and distal end after operation.Following up(20±12)months,the therapy efficacy of all the patients was stable and there was no fracture,removal,aortic stenosis or dysarteriotony.Heart ultrasounds demonstrated good close of the cases with patent ductus arteriosus.Conclusion CP covered stent is a safe and available clinical therapy,featured by minimum aorta injuries.
