Aortopexy offers surgical options for a variety of pathological tracheal conditions in paediatric patients

OBJECTIVES: Aortopexy is widely used; however, many surgeons still regard it with suspicion. To date, there are only a few large series and minimal long-term data. Against this background, our goal was to report our experience, particularly with regard to the recent expansion of indications and modification of diagnostic routine and surgical strategy.

METHODS: Between 1994 and 2012, 53 patients (mean age: 1.1 years; 5 weeks-10.2 years) were operated on. Tracheomalacia after the operation for oesophageal atresia was the main indication for aortopexy (74%), followed by tracheal compression by the innominate artery (17%) and other selected indications (9%). Computed tomography angiography has emerged in recent years as the method of choice for preoperative diagnosis. Median sternotomy has replaced lateral thoracotomy, and intraoperative bronchoscopy has become the standard.

RESULTS: In contrast to magnetic resonance imaging, computed tomography angiography resulted in perfect visualization of the condition. Median sternotomy and simultaneous bronchoscopy led to immediate readjustment of the aortopexy sutures in 6 patients. There were no surgical deaths or serious morbidities. The mean follow-up was 4.9 (0.3-14.9) years. Two patients with additional complex diseases died during the follow-up period. In all survivors, symptoms improved markedly or disappeared. However, we observed an increased susceptibility to lower respiratory tract infections over the long-term (32%).

CONCLUSIONS: Aortopexy is effective for treating tracheomalacia of different origins and other pathological conditions as well. Preoperative computed tomography angiography offers excellent visualization of the condition. Median sternotomy and intraoperative bronchoscopy provide a combination for reliable operative and long-term results. However, many patients still have an increased susceptibility to lower respiratory tract infections.
