Tracheo-innominate artery fistula with continuous bleeding successfully treated through the suprasternal approach: a case report

BACKGROUND: Tracheo-innominate artery fistula (TIF) is a rare but fatal complication occurring after tracheotomy. Brachiocephalic trunk transection, one of the surgical treatments for TIF, is mostly associated with a full or partial median sternotomy. We describe a case of TIF with continuous bleeding, which was successfully treated with brachiocephalic trunk transection through a collar incision without the need for median sternotomy. CASE PRESENTATION: Case 1. An 18-year-old man was referred to our hospital with bleeding from a tracheal stoma, which had ceased prior to admission. TIF was suspected after examination. Innominate artery transection was performed through a collar incision. TIF was not revealed when we cut the innominate artery anterior wall open; therefore, we opted for preventive surgical intervention. The post-operative course was uneventful, and the patient was asymptomatic at the 3-year follow-up. Case 2. A 14-year-old male patient was admitted to our hospital with bleeding from a tracheal stoma, and TIF was suspected after examination. There was persistent bleeding when the cuff of the tracheotomy tube was deflated. Brachiocephalic trunk transection was performed through a collar incision using balloon occlusion. The post-operative course was uneventful, and rebleeding has not occurred 2 years later. CONCLUSIONS: Brachiocephalic trunk transection without any median sternotomy may offer the benefits of post-operative infection prevention. In patients with suspected continuous bleeding, using a balloon catheter may be a safe and effective method of treatment.
