Tracheoarterial fistula in a patient with amyotrophic lateral sclerosis successfully managed by overinflation of the tracheostomy tube cuff alone: a case report.

BACKGROUND: Tracheoarterial fistula is the most devastating complication after tracheostomy, and its mortality, without definitive treatment, approaches 100%. In general, the combination of bedside emergency management, that is, overinflation of the tracheostomy tube cuff, and definitive treatment such as surgical or endovascular intervention is necessary to prevent the poor outcome. Patients with neuromuscular diseases such as amyotrophic lateral sclerosis are susceptible to tracheoarterial fistula because of long-term mechanical ventilation and muscle weakness. CASE PRESENTATION: We describe a case of tracheoarterial fistula in a Japanese 39-year-old patient with amyotrophic lateral sclerosis with long-term ventilator management. The patient was clinically diagnosed with a tracheoarterial fistula because of massive bleeding following sentinel hemorrhage. The massive hemorrhage was controlled by overinflation of the tracheostomy tube cuff alone, without definitive treatment. CONCLUSIONS: This case suggests overinflation of the tracheostomy tube cuff alone plays an important role, semi-permanently, in the management of tracheoarterial fistula, especially in cases where surgical or endovascular intervention is not indicated. Clinicians taking care of patients with tracheostomy undergoing long-term mechanical ventilation should be aware that tracheoarterial fistula might occur following tracheostomy.

Outcomes and complications of simple layered closure of persistent tracheocutaneous fistula after tracheostomy in childhood.

BACKGROUND: Up to half of all children who have a tracheostomy will develop a persistent tracheo-cutaneous fistula (TCF) after decannulation. Surgical closure of the TCF is technically easy but post-operative complications can be immediate and life-threatening. These include air leak from the tracheal repair leading to massive surgical emphysema or pneumothorax. We reviewed our experience of TCF closure to try to identify potential risk factors for complications. METHOD: Retrospective case record review of all children (0-16 years) who underwent surgical TCF closure between January 2010 and December 2021 following development of a persistent TCF after decannulation of a tracheostomy. RESULTS: We identified 67 children. They ranged in age from 14 months to 16 years (median 3 years 10 months) at the time of the TCF closure. Major medical comorbidities were present in 90%. Pre-operative pulse oximetry with the fistula occluded was used in 29 children (43%). An underwater leak test was performed in 28 (42%). A non-suction drain was used in 29 children (43%). Prophylactic antibiotics were prescribed for 30 children (45%). Post-operative complications occurred in 15 children (22%). Life-threatening air leak occurred in the immediate post-operative period in 2 children (3%). Respiratory distress occurred in 3 children (4%) in the recovery area immediately after surgery. None required re-tracheostomy. Three children suffered post-operative pneumonia (4%), and wound infections occurred in 8 children (12%). We were unable to show a significant association between patient or surgical factors and complications. DISCUSSION: Complications for TCF closure are unfortunately common and it is unclear from the available evidence how best to prevent them. Further research is required.

Incidentally Diagnosed Esophago-Pulmonary Fistula on 18F-FDG PET/CT in a Case of Carcinoma Esophagus: A Life-Threatening Emergency.

ABSTRACT: Esophago-pulmonary fistulas are very less reported in literature. 18F-FDG PET/CT scan is routinely used for evaluation of patients of carcinoma esophagus. We present a case of carcinoma esophagus with acquired esophago-pulmonary fistula diagnosed on 18F-FDG PET/CT scan.

Rare case of bilateral pleural effusion caused by pancreaticopleural fistula.

A 51-year-old man presented with dyspnoea and basithoracic pain. Chest X-ray revealed bilateral pleural effusion, which was managed by bilateral chest drain placement. The pleural fluid analysis showed elevated lipase. Subsequent endoscopic retrograde cholangiopancreatography (ERCP) demonstrated a large fistula from the tail of the main pancreatic duct to the left pleural space. Definitive treatment was accomplished with ERCP guided large pancreatic stents placement.

Primary tracheocutaneous fistula closure with immediate transition to nocturnal noninvasive positive pressure ventilation in two children with Congenital Central Hypoventilation Syndrome.

Transitioning children with Congenital Central Hypoventilation Syndrome (CCHS) from nocturnal invasive ventilation via tracheostomy to noninvasive positive pressure ventilation (NIPPV) is challenging due to the leak caused by the tracheocutaneous fistula (TCF), resulting in insufficient ventilation. Decannulation and primary closure of the TCF with immediate transition to nocturnal NIPPV was performed in two children with CCHS at a tertiary care children's hospital. Neither child developed significant adverse effects such as pneumomediastinum or pneumothorax. This technique is a novel approach that may improve decannulation outcomes and aid transition to NIPPV in this patient population.

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.

Endovascular Treatment of Multiple Bronchial Artery Aneurysms With Prominent Fistula to Pulmonary Artery in a Patient With Interstitial Lung Disease: A Case Report and Literature Review.

Bronchial artery aneurysm (BAA) is a rare entity. Ruptured BAA can cause life-threatening hemorrhage. It is recommended that treatment should be initiated immediately after diagnosis. We present the case of a 56-year-old female with multiple BAAs and interstitial lung disease. Aortic computed tomography angiography demonstrated that the largest aneurysm at the right hilum was fed by right subclavian artery and right bronchial artery. A fistula between the pulmonary trunk and the aneurysm was also revealed. The patient underwent transcatheter embolization. Coils were placed in the feeding vessels instead of the aneurysms to avoid nontarget embolization of the pulmonary arteries through the fistula. The procedure achieved reduction in aneurysmal blood flow. The patient's cough resolved at 6-month follow-up.

Empyema with Multiple Bronchopleural Fistulae Improved by Bronchial Occlusion Using an Endobronchial Watanabe Spigot with the Push and Slide Method.

The push and slide method is a method of endoscopic bronchial occlusion using an endobronchial Watanabe spigot that facilitates occlusion of the target bronchus rapidly and accurately using a guidewire. We herein report the case of a man who was diagnosed with empyema forming bronchopulmonary fistulae that was successfully treated by endoscopic bronchial occlusion. Because of the multiple fistulae, balloon occlusion was not a favorable therapeutic approach. Instead, the push and slide method was used in order to detect the fistulae. Endoscopic occlusion, particularly that using the push and slide method, may be a valid treatment option for empyema with multiple bronchopulmonary fistulae.

Multimodal Treatment for Post-Pneumonectomy Bronchopleural Fistula Associated With Empyema.

Post-pneumonectomy bronchopleural fistula associated with empyema still remains a dreaded complication in thoracic surgery. A variety of surgical and endoscopic procedures have been proposed over the years, but none of these has been suitable for all patients. Herein, we report a new multimodal approach, including the insertion of tracheobronchial conical stent, the open pleural packing, and the closure of bronchial stump with omentoplasty. This procedure was successfully applied in 11 patients with post-pneumonectomy bronchopleural fistula with empyema.

Efectividad del colgajo de músculo pectoral mayor miofascial en la reducción de fístulas salivares tras laringectomía total de rescate / Efficacy of the myofascial pectoralis major flap in the reduction of salivary fistulas after salvage total laryngectomy

Introducción: La fístula faringocutánea es la más frecuente de las complicaciones poslaringectomía total. Su incidencia varía entre un 9-25% en pacientes poslaringectomía total primaria, hasta un 14-57% en laringectomía de rescate posradioterapia o posquimioterapia + radioterapia. El colgajo de músculo pectoral mayor miofascial (PMMF) se postula como una herramienta útil para disminuir la incidencia de esta complicación. Material y método: Análisis retrospectivo de pacientes tratados mediante laringectomía total de rescate, asociada o no a refuerzo de sutura faríngea con colgajo de PMMF. Resultados: Veinte pacientes fueron incluidos, 18 hombres (90%) y 2 mujeres (10%), en 10 de los cuales se utilizó colgajo de PMMF. La edad promedio fue de 66,65 años. Diecisiete (85%) presentaron un tumor laríngeo y 3 (15%) un tumor de hipofaringe. Ocho (80%) pacientes del grupo sin PMMF presentaron fístula en el postoperatorio, mientras que tan solo 2 (20%) pacientes del grupo de PMMF presentaron fístula durante el postoperatorio (p = 0,005). El tiempo promedio para el cierre de la fístula fue significativamente menor en los casos en que se empleó el PMMF (16 ± 11 vs. 76,8 ± 67 días, p = 0,001), así como la estancia hospitalaria (19,6 ± 18 vs. 83,9 ± 77 días, p 0,001). Conclusión: El uso del PMMF se asocia a una menor tasa de fístulas poslaringectomía total de rescate en pacientes tratados de forma primaria mediante protocolo de conservación de órgano por cáncer de laringe/hipofaringe, y favorece la cicatrización local disminuyendo el tiempo promedio de cierre de fístulas y la estancia media hospitalaria (AU)

Introduction: Pharyngocutaneous fistula is the most frequent complication after total laryngectomy. Its incidence varies between 9%-25% in post primary total laryngectomy patients, to 14%-57% in salvage laryngectomy post radiotherapy or post chemotherapy + radiotherapy. The pectoralis major myofascial flap (PMMF)is postulated as a useful tool to decrease the incidence of this complication. Materials and method: Retrospective analysis of a group of patients treated by salvage laryngectomy, associated or not with pharyngeal closure reinforcement with PMMF. Results: Twenty patients were included, 18 males (90%) and 2 females (10%), in 10 of whom the PMMF was used. The average age was 66.65 years. Seventeen (85%) had a laryngeal tumour and 3 (15%) had a hypopharyngeal tumour. Eight (80%) patients in the non-PMMF group had postoperative fistula, whereas only 2 (20%) patients in the PMMF group had a fistula during the postoperative period (P = .005). The mean time for fistula closure was significantly shorter in the cases where PMMF flap was used (16 ± 11 days vs. 76.8 ± 67 days, P = .001), as was hospital stay (19. 6 ± 18 days vs. 83.9 ± 77 days, P =. 001). Conclusion: The use of PMMF in our series is associated with a lower rate of post salvage laryngectomy fistulas in patients treated primarily by organ preservation protocol for laryngeal/hypopharyngeal cancer. In turn, it promotes local healing by decreasing the mean duration of fistula closure and the mean hospital stay (AU)

Case report of refractory pericardial effusion associated with lymphatic fistula due to surgical injury during sternotomy.

RATIONALE: A 35-year old Chinese female was admitted to hospital with refractory pericardial effusions 10 days post mitral valve replacement via median sternotomy. We performed an exploratory resternotomy and found lymphatic leakage on the surface of the diaphragm which was continuously emitting a light yellow fluid. PATIENT CONCERNS: The patient complained of no obvious discomfort except for the concern of massive pericardial effusion drainage. DIAGNOSES: Exploratory resternotomy and biochemical testing lead to a supradiaphragmatic lymphatic fistula being diagnosed as the cause of the refractory pericardial effusion. INTERVENTIONS: The fistula was closed with a continuous suture and no other fistulas were found after a thorough exploration. OUTCOMES: The patient was discharged home on postoperative day 5 and recovery was uneventful. LESSONS: In this case a timely exploratory resternotomy proved effective in seeking the cause of and treating pericardial effusion following cardiac surgery.

Spontaneous non-obstructive nephropleural fistula with an autoimmune disorder causing massive urinothorax: a rare association.

Urinothorax, an unusual and rare cause of pleural effusion, is usually secondary to urinary obstruction and abdominal trauma. We describe an uncommon case of left-sided urinothorax in a 35-year-old man with diabetes and hypothyroidism associated with an autoimmune disorder without obvious obstructive uropathy. Workup revealed pancytopenia, mild proteinuria, positive anti-nuclear and anti-dsDNA antibodies suggestive of probable systemic lupus erythematosus. Contrast-enhanced CT-chest and abdomen showed hepatosplenomegaly with bilateral renal abscesses and a fistulous connection between left superior calyx and left the pleural cavity. Patient was initially managed by intravenous antibiotics, intercostal tube drainage and ipsilateral double-J stent placement. The definitive management in the form of closure of nephropleural fistula was achieved with sclerotherapy using 0.1% povidone-iodine instillation, while oral steroids were started for the probable autoimmune disorder. To the best of our knowledge, this is the first case of spontaneous non-obstructive nephropleural fistula associated with an autoimmune disorder, managed by minimally invasive methods.

Endoscopic electrocauterization of pyriform sinus fistula.

To determine the efficacy of endoscopic electrocauterization for pyriform sinus fistula (PSF) using a flexible Bugbee cautery electrode. From 2009 to 2016, a total of eight patients with acute suppurative thyroiditis or cervical abscess secondary to PSF were retrospectively registered in our study (three males, five females; median age 6.5 years). All patients underwent endoscopic electrocauterization as treatment for PSF. Six of eight patients had no recurrence after the initial endoscopic electrocauterization of PSF. One patient with recurrence developed symptoms 9 days after cauterization and another experienced recurrence after 2 years. Mean follow-up for the eight patients was 50 months (range 5-96 months). No post-operative complication was reported. Endoscopic electrocauterization appears to be a less-invasive, safe, and effective method for the treatment of PSF.
