The Treatment of Low Retrosternal Tracheal Stenosis in the Neonate and Small Children

Summary

In the years 1979 to 1983, 8 infants or small children under 2 years of age were treated for severe low retrosternal (carinal) tracheal Stenosis. The etiology was iatrogenic (postintubation) in 7 cases and congenital in one. Low tracheal Stenosis was seen in 0.4% of all intubated (1607 patients) neonates during the same time period.

In 6 cases of acute obstruction, diagnostic bronchoscopy was used to relieve the Stenosis by forcefully dilating the trachea. One patient died and all had severe complications, but 3 children are living and doing well without further treatment. Only Short granular retrosternal stenoses appeared to be suitable for violent dilatation, which is indicated if the patient is otherwise facing death due to suffocation. All other operative facilities must be at hand.

Resection of low retrosternal trachea under cardiopulmonary bypass was performed in 4 patients - 2 of them had had earlier unsuccessful dilatations. One patient, aged 1.5 months, died. In this case the obstruction extended into both bronchi. Another patient was re-resected with success.

The follow-up time of the 3 living patients with resection is already 2.4, 4.5 and 4,7 years respectively. The patients are living a normal life and the anastomoses are growing normally.
