Slide tracheoplasty for congenital tracheal stenosis

Background/purpose

The aim of this study was to add to the experience of slide tracheoplasty in infants with congenital tracheal stenosis (CTS), to review the recent literature on this subject, and to evaluate the diagnostic workup in infants with CTS.

Methods

A retrospective review of 3 infants with CTS treated with slide tracheoplasty was conducted at our institution. They all underwent bronchoscopy, tracheobronchography, and echocardiography. Therapy consisted of slide tracheoplasty and simultaneous correction of associated vascular malformations.

Results

A pulmonary artery sling was missed initially on esophagography in 2 patients. Stridor became worse in 2 patients after tracheobronchography. After surgical therapy, 2 patients survived and were discharged 12 days after surgery. Both are without symptoms at follow-up of 12 and 20 months. One patient had inoperable restenosis and died 27 days after the operation.

Conclusions

Esophagography is not a reliable tool to depict associated vascular anomalies for patients with CTS. According to the literature, computer tomography has become more reliable to depict the tracheobronchial tree and is useful to elucidate associated vascular anomalies as well. Compared with other surgical techniques for infants with CTS reported in the literature, slide tracheoplasty has fewer postoperative complications and comparable survival rates.
