Tracheo-innominate artery fistula with severe motor and intellectual disability: incidence and therapeutic management.

OBJECTIVE

Tracheo-innominate artery fistula (TIF) is a rare but life-threatening complication following tracheostomy or tracheoesophageal diversion (TED). Although successful surgical intervention for TIF has been reported, few studies have been performed in patients with severe motor and intellectual disability (SMID). Therefore, we aimed to analyze TIF in patients with SMID to clarify the clinical variables predicting the occurrence and adequate management for lifesaving of TIF.

METHODS

We retrospectively reviewed the records of patients with SMID undergoing surgical tracheostomy and TED between 2006 and 2012 and identified those with TIF. When TIF occurred, we obtained the clinical status and emergency management.

RESULTS

Of 70 patients who underwent tracheostomy or TED during the study period, three patients had TIFs; in one case, TIF was avoided by ligation of the innominate artery before TED. The incidence of TIF in those undergoing tracheostomy and TED was 2.3% and 7.4%, respectively. The interval between tracheostomy and TIF was 14-50 months.

CONCLUSIONS

Patients with SMID may have an increased risk of TIF. Prompt diagnosis and surgical intervention to control the bleeding is the only effective management at present.
