Objective To evaluate the effectiveness of covered Cheatham-platinum (CP) stent for treatment of coarctation of aorta (CoA). Methods Between January 2007 and September 2013, 15 patients (16 lesions) with CoA underwent covered CP stent implantation, and the clinical data were analyzed retrospectively. Of 15 cases, 8 were male and 7 were female, aged 13-56 years (mean, 27.7 years). Fifteen lesions located beyond the origin of the left subdavian artery, and 1 lesion located between the origin of the left common carotid artery and the origin of the left subdavian artery. Proper covered CP stent and balloon-in-balloon (BIB) catheter were selected according to the data of computed tomography angiography or digital subtraction angiography examination. Under fluoroscopic guidance, the covered CP stent was placed at lesion accurately by expanding the inner balloon and the outer balloon sequentially. The variation of the systolic pressure gradient across the lesion and the stenosis extent of the aorta before and after the procedure were recorded. Results Fifteen patients were all treated by covered CP stent implantation successfully. The systolic pressure gradient across the lesion decreased from (58.1±19.5) mm Hg (1 mm Hg=0.133 kPa) at preoperation to (6.2±5.6) mm Hg at immediate after CP stent implantation, and the stenosis extent of the aorta decreased from 73.8%±12.8% at preoperation to 16.7%±5.6% at immediate after CP stent implantation, all showing significant difference (t=12.483, P=0.000; t=15.631, P=0.000). All puncture points healed well with no aortic dissection, pseudoaneurysm, or obvious subcutaneous hematoma. All the patients could walk moderately within 48 hours after procedure. The average hospitalization time was 11.1 days (range, 6-18 days). During a mean follow-up of 29.7 months (range, 1-81 months), the symptom of dizziness and exercise tolerance were improved obviously, and the systolic pressures gradient between upper and lower extremity was below 20 mm Hg. The systolic and diastolic pressures at last follow-up were significantly improved when compared with preoperative values (t=7.725, P=0.000; t=3.651, P=0.000). According to radiography, the location and shape of the stent were good, and no aortic dissection, aneurysm, or recoarctation occurred. Conclusion According to the initial and midterm results, the covered CP stent is an effective treatment for CoA in adolescents and adults with a low rate of complication. However, long-term results still require further follow-up.
