Tracheoinnominate fistula: acute bleeding and hypovolemic shock due to a trachea-innominate artery fistula after long-term tracheostomy, treated with a stent-graft

A Systematic Review of Mortality Associations in Patients who Develop Tracheoinnominate Artery Fistula Following Tracheostomy

OBJECTIVE

Tracheoinnominate artery fistulas (TIFs) are a rare but deadly complication of tracheostomy. Tracheoinnominate artery fistula cases in the literature were summarized in order to understand mortality associations.

METHODS

MEDLINE was searched for studies reporting individual characteristics of patients with TIFs after tracheostomy, excluding cases without tracheostomy or with additional procedures at the tracheostomy site. This study followed PRISMA guidelines.

RESULTS

121 TIF patients from 18 case series and 46 case reports were included. The median age was 40 years, and 52.9% were male. The overall mortality rate was 64.5%. There were differences in mortality between cases that presented initially with vs without sentinel bleeding (odds ratio [OR] .34; CI [confidence interval] .16-.73; P = .006). The mortality rate also differed in whether or not the tracheostomy cuff was over-inflated for temporary hemostasis during resuscitation (OR 3.57 (CI 1.57-8.09); P = .002). Treatment compared to no treatment had lower mortality rates (OR .11 (CI 0.04-.32); P < .001); no differences were found if treatment was endovascular vs open surgical.

CONCLUSIONS

Mortality is a major concern after detection of a TIF and resuscitation paired with endovascular or open surgical intervention is imperative. Rapidly investigating sentinel bleeds and intervening upon hemorrhage with temporary cuff over inflation may lead to improved outcomes.

Over-Inflating a Tracheostomy Tube Cuff for Tracheo-Innominate Artery Fistula

We report an angiographic image of a 58-year-old woman with profuse bleeding from a tracheo-innominate artery fistula. It may not have been possible to obtain this valuable image if adequate initial resuscitation and an over-inflated tracheostomy tube cuff had not been administered to stop bleeding during an emergency.

Percutaneous tracheostomy: Comparison of three different methods with respect to tracheal cartilage injury in cadavers—Randomized controlled study

Background: Performing tracheostomy improves patient comfort and success rate of weaning from prolonged invasive mechanical ventilation. Data suggest that patients have more benefit of percutaneous technique than the surgical procedure, however, there is no consensus on the percutaneous method of choice regarding severe complications such as late tracheal stenosis. Aim of this study was comparing incidences of cartilage injury caused by different percutaneous dilatation techniques (PDT), including Single Dilator, Griggs’ and modified (bidirectional) Griggs’ method.

Materials and methods: Randomized observational study was conducted on 150 cadavers underwent post-mortem percutaneous tracheostomy. Data of cadavers including age, gender and time elapsed from death until the intervention (more or less than 72 h) were collected and recorded. Primary and secondary outcomes were: rate of cartilage injury and cannula malposition respectively.

Results: Statistical analysis revealed that method of intervention was significantly associated with occurrence of cartilage injury, as comparing either standard Griggs’ with Single Dilator (p = 0.002; OR: 4.903; 95% CI: 1.834–13.105) or modified Griggs’ with Single Dilator (p &lt; 0.001; OR: 6.559; 95% CI: 2.472–17.404), however, no statistical difference was observed between standard and modified Griggs’ techniques (p = 0.583; OR: 0.748; 95% CI: 0.347–1.610). We found no statistical difference in the occurrence of cartilage injury between the early- and late post-mortem group (p = 0.630). Neither gender (p = 0.913), nor age (p = 0.529) influenced the rate of cartilage fracture. There was no statistical difference between the applied PDT techniques regarding the cannula misplacement/malposition.

Conclusion: In this cadaver study both standard and modified Griggs’ forceps dilatational methods were safer than Single dilator in respect of cartilage injury.

A Case of Tracheo-innominate Artery Fistula after Tracheostomy Successfully Treated with a Covered Stent

A 78-year-old man underwent a tracheostomy after embolization for a dural arteriovenous fistula. Seventy days after tracheostomy, arterial bleeding appeared through the tracheal stoma. The bleeding stopped spontaneously. However, two days later, arterial bleeding reappeared, and he was diagnosed with a tracheo-innominate artery fistula (TIF). He then underwent urgent endovascular covered stent placement. After the procedure, there was no bleeding. TIF can be a fatal complication after tracheostomy and it is generally treated with open chest surgery. However, a successful endovascular treatment for TIF has recently been reported and may yield better results.

Prevention of Tracheo-Innominate Artery Fistula Formation as a Complication of Tracheostomy: Two Case Reports

Tracheo-innominate artery fistula (TIF) is a rare complication of tracheostomy and refers to the formation of a fistula between the trachea and innominate artery. Because TIF is fatal, prevention rather than treatment is very important. Here we report the cases of two high-risk patients who underwent tracheostomy, and in whose cases attempts were made to lower the risk of TIF. In the first patient who developed a chest deformity with Duchenne muscular dystrophy, a tracheostomy was performed with a high-level (cricothyroid level) approach compared with the standard tracheostomy. In the second patient, the thoracic cage was relatively small due to a giant omphalocele, and the risk of a fistula forming was decreased by wrapping the innominate artery with an opened polytetrafluoroethylene vascular graft after resolving crowding of the intrathoracic cavity by total thymectomy. There was no TIF occurrence at the outpatient follow-up in either case. We expect that our approaches may be effective intervention measures for preventing TIF.
