Abstract:
Objective To evaluate the NuMED covered CP stent for the treatment of adult aortic coarctation.Methods 6 patients with coarctation of the aorta received covered CP stent implantation.There were 4 males and 2 females cases with mean age of (20.13±5.16) years old.The size of the covered CP stents and balloons were determined by preoperative aortic CTA assessment.Stent implantation was per formed through femoral approach and the puncture site was sealed by vascular closure device after the operation.Results All the NuMED covered CP stents were implanted successfully.The pressure gradient dropped from (59.32±15.78) mmHg to (10.83±3.66) mmHg (P<0.001) after stenting.The diameter of the coarcation at the narrowest point increased from preoperative (5.1±1.2) mm to (19.7±2.4) mm after stenting (P<0.001).In 2 cases with PDA, the shunting disappeared spontaneously after operation with normalized of lower limb blood pressure.All the patients were followed up clinically for 12-36 months and all of them reported improvement in clinical symptoms post operation.Follow up Doppler echo or aorta CTA examinations at 3 months showed no restenosis.No mortality recorded during follow up.Conclusions NuMED covered CP stent for the treatment of aortic coarctation in adults showed satispactony short term outcome.Its long term outcome still requires further in vestigation.
