PURPOSE: The innominate artery sometimes compresses the trachea, leading to tracheomalacia and highly fatal tracheoinnominate fistula in patients with severe chest deformity. This study is focused on the indication of innominate artery transection for the definitive treatment of these complications. PATIENTS AND METHODS: We retrospectively analyzed the medical records of eight patients who underwent transection of innominate artery. RESULTS: All patients had developed severe chest deformity and their symptoms were life-threatening anoxic spell or endotracheal hemorrhage. Bronchoscopy showed tracheomalacia with or without pulsatile granulations on the anterior wall of the trachea underlying the innominate artery. In six cases who had previously undergone tracheostomy or laryngotracheal separation, the tracheal tube tip made granulations or tracheoinnominate fistulas. In addition to transection of innominate artery, the tracheoinnominate fistula was closed in two cases and the artery was transposed in one. All patients survived without neurologic complications and airway symptoms postoperatively. CONCLUSIONS: For patients with severe chest deformity, innominate artery transection is indicated when they have tracheal compression by the artery and need to be intubated through the compressed part of trachea to secure the airway. This would be the best timing to schedule the prophylactic operation.
