Tracheo-innominate artery fistula: Diagnosis and surgical management

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.

Early postoperative complications following tracheotomy: Does suturing technique influence outcomes?

Introduction

Tracheotomy is one of the most commonly performed procedure by otolaryngologists, but no consensus exists on the effect of suturing techniques on postoperative complications. Stay sutures and Bjork flaps are utilized frequently for securing the tracheal incision to the neck skin in order to create a tract for recannulation.

Methods

Retrospective cohort study of tracheotomies performed by Otolaryngology-Head and Neck Surgery providers (May 2014 to August 2020) was conducted to determine the effect of suturing technique on postoperative complications and patient outcomes. Patient demographics, medical comorbidities, indication for tracheostomy, and postoperative complications were analyzed with a statistical alpha set of .05.

Results

Out of 1395 total tracheostomies performed at our institution during the study period, 518 met inclusion criteria for this study. Three hundred and seventeen tracheostomies were secured by utilizing a Bjork flap, while 201 were secured with up and down stay sutures. Neither technique was noted to be more commonly associated with tracheal bleeding, infection, mucus plugging, pneumothorax, or false passage of the tracheostomy tube. One mortality was noted following decannulation during the study period.

Conclusion

Though various techniques exist; adverse outcomes are not associated with the manner in which a new tracheostomy stoma is secured. Medical comorbidities and the indications for tracheostomy likely play a more significant role in postoperative outcomes and complications.

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.

Successful management of a tracheomalacia patient with active endotracheal bleeding due to intraoperative innominate artery injury: A case report

RATIONALE

Intraoperative innominate artery injury is life-threatening in tracheomalacia patients with prolonged tracheostomy. Anesthetic management is challenging in cases with massive hemorrhage into the endotracheal tube. We report a case in which we successfully managed a tracheomalacia patient with acute endotracheal bleeding due to innominate artery injury.

PATIENT CONCERNS

A 24-year-old patient with tracheomalacia was scheduled to undergo exploratory thoracotomy for the treatment of intermittent bleeding at the tracheostomy site. During exploration, sudden active bleeding due to innominate artery injury was observed in the endotracheal lumen.

DIAGNOSES

The patient was diagnosed with tracheomalacia.

INTERVENTIONS

We immediately used the bronchoscope to place the tip of the endotracheal tube at the bleeding site and hyperinflated the cuff.

OUTCOMES

The ballooned cuff compressed the active bleeding site, so no additional bleeding was detected by bronchoscopy, and no additional massive bleeding was observed in the operative field.

LESSONS

Immediate and appropriate overinflation of the endotracheal tube cuff by an anesthesiologist may provide improved surgical field visibility and time for critical surgical procedures in cases of massive hemorrhaging.

Therapeutic outcomes of laryngeal closure and laryngostomy in children with recurrent pneumonia

PURPOSE

Children with medical complexity frequently experience difficulty breathing and swallowing and occasionally develop aspiration pneumonia. Long-term intubation may cause fatal trachea-innominate artery fistula (TIF). In the present study, we retrospectively evaluated the efficacy of laryngeal closure and laryngostomy in children with medical complexity.

MATERIALS AND METHODS

Laryngeal closure and laryngostomy were performed in eight children with severe neuromuscular disorders who were incapable of oral ingestion and verbal communication. The laryngostoma was placed at a higher position compared to that in conventional tracheostomies for easier management of the airway and to prevent TIF.

RESULTS

Aspiration was successfully prevented postoperatively in all cases. Laryngocutaneous fistula formation was not observed. Two patients successfully achieved oral ingestion capability and tracheal cannulas were removed in two patients. Among the six patients who needed a mechanical ventilator before surgery, two patients were weaned from mechanical ventilation. Five patients were successfully discharged from the hospital. Although two patients died because of their primary condition, pneumonia exacerbation was not observed in any of the patients.

CONCLUSION

Compared to the conventional tracheostomy, our procedure improved airway management and function in children with medical complexity and reduced the risk of TIF.

Consensus of free flap complications: Using a nomenclature paradigm in microvascular head and neck reconstruction

BACKGROUND

We aim to define a set of terms for common free flap complications with evidence-based descriptions.

METHODS

Clinical consensus surveys were conducted among a panel of head and neck/reconstructive surgeons (N = 11). A content validity index for relevancy and clarity for each item was computed and adjusted for chance agreement (modified kappa, K). Items with K < 0.74 for relevancy (i.e., ratings of "good" or "fair") were eliminated.

RESULTS

Five out of nineteen terms scored K < 0.74. Eliminated terms included "vascular compromise"; "cellulitis"; "surgical site abscess"; "malocclusion"; and "non- or mal-union." Terms that achieved consensus were "total/partial free flap failure"; "free flap takeback"; "arterial thrombosis"; "venous thrombosis"; "revision of microvascular anastomosis"; "fistula"; "wound dehiscence"; "hematoma"; "seroma"; "partial skin graft failure"; "total skin graft failure"; "exposed hardware or bone"; and "hardware failure."

CONCLUSION

Standardized reporting would encourage multi-institutional research collaboration, larger scale quality improvement initiatives, the ability to set risk-adjusted benchmarks, and enhance education and communication.

Challenge for management without tracheostomy tube after laryngo-tracheal separation in children with neurological disorders

OBJECTIVES

The present study analyzed surgical outcomes of laryngotracheal separation (LTS) in children with neurological disorders. The purpose of this study was to investigate respiratory impairment and severe complications after LTS in children, and identify the possibility of permanent tracheostomy without a tracheostomy tube as the safest respiratory management method.

METHODS

Twenty-eight patients (male:female = 16:12) with neurological disorders (6 months to 32 years) who underwent LTS between January 2012 and April 2018 were reviewed. Tracheal diameter, Cobb angle, and sternocervical spine distance (SCD) were measured to assess the potential risk and possibility of removing tracheostomy tube management.

RESULTS

Tracheostomy tube could be removed shortly after LTS in 57% (16/28). However, nine of these patients developed respiratory problems that required tracheostomy tube placement 2 years after LTS. New requirements for a tracheostomy tube as a stent were strongly correlated with SCD (P < .05, odds ratio > 1) as well as tracheal deformity.

CONCLUSIONS

Respiratory management in neurologically impaired children after LTS without a tracheostomy tube is challenging because thoracic deformity during physical growth affects tracheal disfiguration. Thoracic deformities and progression of scoliosis should be considered in respiratory management approaches in children with neurological disorders, and long-term follow-up by computed tomography is necessary.

Tracheal stenosis due to cervicothoracic hyperlordosis in patients with cerebral palsy treated with posterior spinal fusion: a report of the first two cases

Background

Spinal deformity is frequently identified in patients with cerebral palsy (CP). As it progresses, tracheal stenosis often develops due to compression between the innominate artery and anteriorly deviated vertebrae at the apex of the cervicothoracic hyperlordosis. However, the treatment strategy for tracheal stenosis complicated by spinal deformity in patients with CP remains unknown.

Case presentation

This study reports two cases: a 19-year-old girl (case 1) and a 17-year-old girl (case 2), both with CP at Gross Motor Function Classification System V. Both patients experienced acute oxygen desaturation twice within the past year of their first visit to our department. X-ray and computed tomography revealed severe scoliosis and cervicothoracic hyperlordosis causing tracheal stenosis at T2 in case 1 and at T3-T4 in case 2, suggesting that their acute oxygen desaturation had been caused by impaired airway clearance due to tracheal stenosis. After preoperative halo traction for three weeks, both patients underwent posterior spinal fusion from C7 to L5 with Ponte osteotomy and sublaminar taping at the proximal thoracic region to correct cervicothoracic hyperlordosis and thoracolumbar scoliosis simultaneously. Postoperative X-ray and computed tomography revealed that the tracheal stenosis improved in parallel with the correction of cervicothoracic hyperlordosis. Case 1 did not develop respiratory failure 1.5 years after surgery. Case 2 required gastrostomy postoperatively due to severe aspiration pneumonia. However, she developed no respiratory failure related to impaired airway clearance at one-year follow-up.

Conclusions

We present the first two cases of CP that developed tracheal stenosis caused by cervicothoracic hyperlordosis concomitant with progressive scoliosis and were successfully treated by posterior spinal fusion from C7 to L5. This enabled us to relieve tracheal stenosis and correct the spinal deformity at the same time. Surgeons must be aware of the possibility of coexisting tracheal stenosis in treating spinal deformity in patients with neurological impairment because the surgical strategy can vary in the presence of tracheal stenosis. This study demonstrated that some patients with CP with acquired tracheal stenosis can be treated with spinal surgery.

Tracheoinnominate Artery Fistula Treated With Endovascular Stent Graft at a Level I Trauma Center

Tracheoinnominate artery fistula could be a fatal complication of tracheostomy. Herein, we present the case of a 59-year-old male with sentinel bleeding around the tracheostomy with subsequent workup revealing a tracheoinnominate fistula. Subsequently, the patient was managed with an endovascular approach with a subsequent favorable outcome. We reported an alternative approach to the management of this catastrophic complication in patients who are at high risk for complications from conventional treatment approach.

Tracheo-innominate Artery Fistula in a Complicated Penetrating Neck Trauma: A Successfully Managed Rare Complication of Low Tracheotomy

Tracheo-innominate artery fistula is a rare complication of tracheotomy with very high mortality rate. Only a few patients survive this complication as reported in the literature. Here we report the case of a 54-year-old gentleman who presented to the emergency department with a history of penetrating neck trauma following a road traffic accident. Neck exploration and tracheotomy were done to secure the airway. After two weeks, the patient had an episode of massive stomal bleed for which he was taken to the operating room and re-explored. A tracheo-innominate artery fistula was detected, and right side aorto-carotid and right side aorto-subclavian anastomoses were done using reversed saphenous vein graft with interruption of flow. Following a successful surgery, the patient was decannulated later, and now lives a healthy normal life. Early diagnosis and immediate intervention are the key in managing this complication. Bedside management also plays a vital role.

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.

Successful emergency management of a bleeding tracheoinnominate fistula

In this case, we describe a novel approach to achieving temporary haemostasis in acute massive haemorrhage from a bleeding tracheoinnominate fistula. We report the case of a 42-year-old man admitted to hospital after suffering 80% body surface area burns. Thirty days following the percutaneous insertion of a tracheostomy, spontaneous massive haemorrhage occurred via the tracheostomy stoma, the tracheostomy tube and the mouth. After hyperinflation of the tracheostomy cuff which controlled airway contamination, effective tamponade was achieved using a hyperinflated balloon on a Foley catheter that was introduced by direct laryngoscopy into the upper larynx above the tracheotomy stoma. This provided temporary control of the bleeding until definitive management through ligation of the innominate artery via median sternotomy.

[Surgical treatment of tracheoarterial fistulas]

BACKGROUND

A tracheoarterial fistula (TAF) is an uncommon but life-threatening complication after tracheostomy. Only an immediate and targeted treatment provides a chance to survive.

OBJECTIVE

Surgical treatment of TAF.

METHODS

Selective review of the literature and case description.

RESULTS

A TAF leads to an acute bleeding complication with displacement of the respiratory tract. The mortality rate is nearly 100% without a surgical intervention. In the literature various interventional and surgical treatment procedures are described. Rapid control of bleeding via manual compression and overinflation of the tracheal cuff are the most important steps of treatment. Subsequent emergency surgery with ligation or resection of the TAF and covering of the tracheal lesion should be performed. Extracorporeal membrane oxygenation (ECMO) and a heart-lung machine can sometimes be necessary.

CONCLUSION

Despite all treatment options the mortality rate of TAF remains high. The critical steps are a quick diagnosis of TAF, securing the airway and immediate bleeding control.

Endovascular management of tracheo-innominate artery fistula: a case report and literature review

Tracheo-innominate artery fistula (TIF) is a rare complication of tracheostomy, with incidence ranging from 0.1 to 1%, but mortality is high in untreated cases. Early signs range from self-limited bleeding to massive hemorrhage with hypovolemic shock. The caliber of the tracheostomy cannula, its position in contact with the tracheal wall, and tracheal cuff pressure can traumatize the mucosa and trigger development of a TIF. We describe the case of a 14-year-old female patient who had been tracheostomized at the age of eight because of head trauma. She later developed subglottic stenosis requiring dilation sessions for six years. During the fifth year of these sessions, she presented repetitive hemoptysis, initially treated by surgery to implant an expanded polytetrafluoroethylene graft. One year later, she had an intense hemorrhage, which was controlled using endovascular techniques followed by definitive surgery, performed electively. The patient was followed up for six months, without complications.

Tracheo-innominate fistula in children: A systematic review of literature

OBJECTIVE

Tracheo-innominate fistula (TIF) is a rare but fatal complication of tracheotomy. To date, there is a paucity of literature regarding pediatric TIFs. The objectives of this study were to conduct a systematic review of literature on pediatric TIF following tracheotomy and describe three demonstrative cases from our institutional experience.

METHODS

We conducted a systematic review using MEDLINE, Embase, Cochrane Database of Systematic Reviews, Web of Science, and CINAHL. All studies with pediatric patients (under 18 years of age) who developed TIF following tracheotomy were included.

RESULTS

Fifty-four publications met inclusion criteria, reporting on 77 cases. The most common indication for tracheotomy was prolonged intubation and the need for ventilatory support (38.6%), with neurological comorbidities being the most common indication (72.7%). The mean time to TIF was 395.7 days (95% confidence interval, 225.9-565.5). Fifty-four patients (70.1%) presented with massive hemorrhage, whereas 18 patients (23.3%) presented with a sentinel bleeding event. The most common diagnostic interventions were computed tomography scan with or without contrast and bronchoscopy (55.8%). A substantial number of patients did not have any investigations (41.6%). Surgical management occurred in 70.1% of patients. Mortality was 38.6% in reported cases with variable follow-up periods.

CONCLUSION

TIF may occur in long-term tracheostomy-dependent children, contrary to the conventionally described 3-week postoperative period. The mortality may not be as high as previously reported with timely intervention. Our results are limited by inherent risks of bias. Further research including well-designed cohort studies are needed to guide an evidence-based approach to TIF.

Tracheoinnominate Artery Fistula Formation in a Child with Long-Term Tracheostomy Dependence

We report a fatal tracheoinnominate artery fistula (TIF) in a 13-year-old female patient with long-term tracheostomy tube dependence due to chronic respiratory failure. Thirteen years after placement of her tracheostomy tube, the patient experienced two separate episodes of sentinel bleeding prior to a fatal hemorrhagic event. Diagnostic evaluation after the sentinel events was mostly nonconclusive. This case highlights the risk of TIF in pediatric age group, even years after initial tracheostomy tube placement, and the need for a high index of suspicion for TIF when children present with unexplained tracheal bleeding.

Risk assessment of high-lying innominate artery with neck surgery

CONCLUSION

A high-lying innominate artery (the upper edge of the innominate artery across the anterior midline of the trachea located 2 cm above the suprasternal notch), a rare situation, may produce disturbance to related anterior cervical tracheal surgery and even cause serious complications.

OBJECTIVES

High-lying innominate artery is a high risk factor in anterior cervical tracheal surgery. Pre-operative assessment via imaging technique can help to familiarize the artery and reduce the related disturbance to the surgery.

METHODS

A total of 829 patients were selected. Cervical computed tomography (CT) examination was conducted before surgery. The distance between the upper edge of the innominate artery across the anterior midline of the trachea and the suprasternal notch was measured. The exposure of innominate arteries in these cases during surgery was recorded.

RESULTS

The upper edge of the innominate artery was located above the suprasternal notch in 26.4% (219/829) of patients. The upper edge of the innominate artery across the anterior midline of the trachea was 2 cm above the suprasternal notch in 18 cases, accounting for 2.2% of all cases, and innominate arteries were exposed in 11 cases (61.1%) during surgery.

Comparison of synchronous versus staged surgeries for patients with synchronous double cancers of the esophagus and head-and-neck

Esophageal and head and neck (H&N) cancers often occur synchronously, this study aimed to clarify the benefits and disadvantages of synchronous and staged operations for double H&N/esophagus cancers. We retrospectively reviewed 43 patients with synchronous double cancer of H&N and esophagus treated between July 2005 and July 2014, of whom 33 patients underwent synchronous operation (SYN) and 10 underwent staged operations (STG). We compared the short-term outcomes between the groups. Operation time was longer, amount of blood loss was larger, and hospital stay was longer in the SYN group than in each single surgery of the STG group. Incidence of postoperative complications did not differ between the groups. Tracheal necrosis was observed only in the SYN group. One patient died because of postoperative bleeding in the SYN group, whereas no mortality was seen in the STG group. Both the peripheral white blood cell counts and serum CRP levels during postoperative period were significantly higher in the SYN group than each single surgery of STG group. The staged surgery strategy for patients with synchronous esophagus/H&N cancers can attenuate surgical stress and thus may increase safety.

Endovascular stenting of tracheoinnominate fistula after tracheostomy in a 14-year-old boy

Tracheoinnominate artery fistula is a rare, fatal complication of tracheostomy, and prompt diagnosis and management are imperative. We report the case of tracheoinnominate artery fistula after tracheostomy in a 14-year-old boy with a history of severe periventricular leukomalacia, hydrocephalus, cerebral palsy, and epilepsy. The tracheoinnominate artery fistula was successfully treated with a stent graft insertion via the right common femoral artery. Endovascular repair of the tracheoinnominate artery fistula via stent grafting is a safe, effective, and minimally invasive treatment for patients in poor clinical conditions and is an alternative to traditional open surgical treatment.

Damage control management of innominate artery injury with tracheostomy

Innominate artery injury is a rare, but catastrophic complication of tracheostomy. We present a case of severe hemorrhagic shock in a 79-year-old male with innominate artery injury that occurred during tracheostomy. Despite temporary innominate artery isolation, the regional forehead saturation was 60 % without laterality. Because adequate cerebral blood flow was apparently maintained through collateral flow, we ligated the innominate, right carotid, and subclavian arteries. We confirmed adequate blood flow to the brain and the right subclavian artery through collateral circulation after ligation using computed tomographic angiography. A damage control management, which involves ligating the injured innominate artery to arrest hemorrhage and monitoring regional forehead saturation for brain ischemia, can be a considerable procedure for the treatment of severe hemorrhagic shock due to innominate artery injury.

Efficacy of Staged Treatment Strategy for Patients with Synchronous Double Cancers of the Esophagus and Head and Neck: A Retrospective Study

BACKGROUND

Synchronous occurrence of esophageal and head and neck (H&N) cancers is frequently observed.

METHODS

We retrospectively reviewed the records of 109 patients with synchronous double cancers of the esophagus and H&N treated between 2005 and 2011. Fifty-one patients underwent synchronous treatment and 58 underwent staged treatment. We measured the delay in treatment for the second cancer in the staged treatment group and evaluated how many patients experienced progression of the second cancer during the first cancer treatment. Overall survival (OS) was analyzed in 100 patients who underwent potentially curative treatment.

RESULTS

Synchronous treatment strategy was frequently selected for patients with both advanced cancers (77 %) compared with those who had early cancers in either or both organs (43 %) (P = 0.02). The median delay in the treatment for the second cancer was 80 days; 77.5 days in the H&N-first group and 96 days in the esophagus-first group. Only one patient experienced stage progression during the waiting period. There was no significant difference in OS between the synchronous treatment group and the staged treatment group (P = 0.73), and no significant difference in OS among patients who had advanced cancer in the H&N, esophagus, or both.

CONCLUSIONS

Prognosis of patients with synchronous cancers depends on that of the more advanced cancer, and waiting for treatment of early cancers may not influence survival. The staged treatment strategy is acceptable when either of the double cancers is at an early stage.

Evidenced-based management of haemoptysis by otolaryngologists

BACKGROUND

Haemoptysis is an uncommon presenting symptom to the ENT clinic and ward, but has potentially sinister aetiology. This article aims to provide a systematic and evidence-based method of managing patients with haemoptysis.

METHODS

The data in this article are based on a literature search performed using PubMed in August 2013. The keywords used included 'haemoptysis' in combination with 'otolaryngology', 'ENT', 'head & neck', 'diagnosis', 'management', 'investigations' and 'treatment'.

RESULTS

The majority of published literature on the subject is level IV evidence. However, this can guide ENT specialists in assessing, investigating and managing presentations of haemoptysis.

CONCLUSION

Understanding the different causes of haemoptysis is important for the otolaryngologist. The main concern is the detection of a malignant lesion in the upper aerodigestive tract or tracheobronchial tree. A thorough history and systematic examination can aid diagnosis.
