Covered Cheatham-Platinum stent implantation for the treatment of coarctation of the aorta:preliminary results in 11 patients / 介入放射学杂志

ABSTRACT

Objective To discuss the efficacy and safety of covered Cheatham-Platinum stent (CCPS) implantation in treating coarctation of the aorta (CoA).Methods The clinical data of 11 patients with CoA who had received CCPS implantation were retrospectively analyzed.Results Successful implantation of single CCPS was accomplished in all 11 patients.After the implantation,the diameter of coarctation site was immediately dilated from preoperative (4.76+0.89) mm to postoperative (12.86+0.90) mm (t=24.86,P＜0.001),and the average systolic blood pressure difference across the coarctation was immediately reduced from preoperative (38.55+10.02) mmHg to postoperative (9.82+6.60) mmHg,the difference was statistically significant (t=10.8,P＜0.001).The patients were followed up for 3-79 months,with a mean of (31.91±27.58) months.The clinical symptoms were relieved in all patients and the activity tolerance was obviously improved.No complications such as endoleak,acute injury of aortic wall,re-coarctation or re-stenosis,vascular injury of puncture site,or death occurred in all patients.Conclusion For the treatment of CoA,implantation of CCPS has excellent short-term and mid-term effect,meanwhile,this technique can effectively avoid complications such as aortic wall iniurv.(J Intervent Radiol.2017.26211-214)
