A prospective study of 11 patients who were treated during the past 10 years was carried out. Of these, five patients underwent endoprosthesis (group A) and six an open surgical repair (group B). Follow-up comprised monitoring of the blood pressure, echocardiography, and computed tomography and magnetic resonance angiographic studies.
The mean age of the patients was 46 years (range: 17-67 years) and the mean follow-up was 52.6 months (range: 1-117 months; 32.3 for group A vs. 69.7 for group B; p ¼ 0.01). Two cases in group A were recoarctations after child angioplasty. The rate of postoperative complications was 27.7%(one hemothorax forgroupAvs.onepneumothoraxandonehemothorax for groupB);however, mortality did not occur. The success rate of the endovascular techniquewas 80%.The stay in the intensive care unit was 2.3 days with significant differences (one group A vs. three group B; p ¼ 0.01), whereas length of hospital stay was 11 days (7.8 group A vs. 11.83 group B; p ¼ 0.17). The pressure gradient across the stenosis decreased by 21.9 ± 3.7mmHg (24.5 ± 4.3 groupAvs. 33 ± 3.2 group B). Six patients (54.5%) showed persistent hypertension (80% group A vs. 33% group B), with a mean residual pressure gradient of 23.4 ± 4.3 mm Hg (22.5 ± 5.4 group A vs. 22 ± 2.1 group B; p ¼ 0.58).
