Endovascular exclusion of complex postsurgical aortic arch pseudoaneurysm using vascular plug devices and a review of vascular plugs

We report the management of a patient presenting with haemoptysis due to aortobronchial fistula. He had previously undergone emergency exclusion bypass of a ruptured pseudoaneurysm developing post-aortic coarctation repair. Computed tomography scan showed persistent filling of pseudoaneurysm sac from proximal and distal aortic ligature sites tied during previous exclusion bypass surgery. Successful exclusion of aneurysm was achieved by using 3 vascular plug devices (1 Amplatzer plug II and 2 Amender patent ductus arteriosus occluder devices). We also review types of Amplatzer vascular plugs and their use in peripheral vascular interventions.

[Nutritional treatment for bronchopleural fistula-promising effect of arginine as a pharmaconutrient]

Pharmaconutrition, which is a supportive nutritional care of surgical patients, has been proven to shorten hospital stay, decrease the incidence of infection, and reduce hospital costs in selected groups of patients. Arginine, one of the most essential pharmaconutrients, has also been proven to enhance would healing process. In severely malnourished patients like bronchopleural fistula with resultant empyema, aggressive nutritional approach should be mandatory. And management of the fistula is also important in stabilizing the ongoing infection. Our hypothesis was that basic nutritional support enhanced with arginine would be effective in not only improving the general condition including nutritional status but also in healing the fistula. We report a case of major bronchopleural fistula in which arginine-supplemented diet as well as aggressive nutritional support could accelerate the postoperative recovery after open thoracic window, ultimately leading to the healing of the fistula.

[Bronchoesophageal fistula secondary to mediastinal lymph node tuberculosis: a case report and review of the literature]

OBJECTIVE

To analyze the clinical features of 1 case of bronchoesophageal fistula (BEF) secondary to mediastinal lymph node tuberculosis.

METHODS

The clinical, auxiliary examinational and pathological data of 1 case with BEF were presented, and the literatures were reviewed.

RESULTS

The patient was a 19 year old female, who was admitted to hospital because of fever and cough associated with liquid intake. It was diagnosed by chest CT scan, endobronchial ultrasound biopsy of mediastinal lymph nodes, and clinical testing (methylene blue). The BEF was closed after anti-tuberculosis therapy and preventing contamination of the fistula by indwelling stomach tube.

CONCLUSIONS

Bronchoesophageal fistula secondary to mediastinal lymph node tuberculosis is rare. Chest CT scan, fiberoptic bronchoscopy, and clinical testing (methylene blue) are useful diagnostic tools for BEF.

Plastic tube-assisted gastroscopic removal of embedded esophageal metal stents: A case report

A patient with stent embedding after placement of an esophageal stent for an esophagobronchial fistula was treated with an ST-E plastic tube inserted into the esophagus to the upper end of the stent using gastroscopy. The gastroscope was guided into the esophagus through the ST-E tube, and an alligator forceps was inserted into the esophagus through the ST-E tube alongside the gastroscope. Under gastroscopy, the stent wire was grasped with the forceps and pulled into the ST-E tube. When resistance was met during withdrawal, the gastroscope was guided further to the esophageal section where the stent was embedded. Biopsy forceps were guided through a biopsy hole in the gastroscope to the embedded stent to remove silicone membranes and connection threads linking the Z-shaped wire mesh. While the lower section of the Z-shaped stent was fixed by the biopsy forceps, the alligator forceps were used to pull the upper section of the metal wire until the Z-shaped metal loops elongated. The wire mesh of the stent was then removed in stages through the ST-E tube. Care was taken to avoid bleeding and perforation. Under the assistance of an ST-E plastic tube, an embedded esophageal metal stent was successfully removed with no bleeding or perforation. The patient experienced an uneventful recovery after surgery. Plastic tube-assisted gastroscopic removal of embedded metal stents can be minimally invasive, safe, and effective.

Open window thoracostomy for the treatment of bronchopleural cutaneous fistula -- case report

Pleural empyema and bronchopleural fistula (the communication between the pleural space and the airways) are early or late complications of various diseases. We present the case of a 29-year-old patient operated for cavitary pulmonary tuberculosis and giant caseoma at the age of seven, who also had fibrocavitary pulmonary tuberculosis positive for mycobacterium tuberculosis at the age of 19. The patient presented with low grade fever, chills, sweating, cough with mucopurulentsputum, dyspnea on mild exertion, perioral cyanosis, cyanosis of the limbs at exertion, anorexia, weight loss and skin suppuration on the left side of thorax. The diagnosis of chronic pulmonary suppuration, the failure of conservative therapy (multiple antibiotic treatments in the last three years), the presence and size of the bronchopleural cutaneous fistula, thepatient's surgical history (presence of "lifesaving"sutures), as well as his immunocompromised state required that conservative medical treatment (antibiotics, antimycotics and supportive medication for six months) be associated with surgery. An open window thoracostomy was selected over segmentectomy or lobectomy due to their associated risks caused by anatomic changes in the large vessels. The open window thoracostomy should not be forgotten or abandoned as it may be the only approach that ensures patient survival and the effective management of the residual cavity and chronicsuppuration in selected cases.

First case of bronchiolar-pleural fistula repair with platelet-leukocyte rich gel

Bronchiolar-pleural fistulas are a frequent complication of thoracic surgery. Current treatment strategies and their invasiveness are quiet different, but often surgeons decide for a new surgical intervention and definitive closure of the breach. We report the case of a bronchiolar-pleural fistula in a 75 years old man with important co-morbidities that we treated with instillation of platelet-leukocyte rich gel (PLR-G). We discuss actual indications for PLR-G as well as its possible role in thoracic surgery.

[Two cases of airway stent placement to treat tracheal and bronchial fistula using general anesthesia under spontaneous respiration]

Anesthesia for the tracheobronchial stent placement involves the risk of airway narrowing and obstruction. Controlled ventilation with relatively high airway pressure is usually used to maintain oxygenation and ventilation during anesthesia. However, controlled ventilation does not always provide tidal volume and oxygenation due to gas leakage from tracheobronchial fistula. We report 2 cases of general anesthesia under spontaneous respiration for the airway stent placement to treat tracheal and bronchial fistula. Case 1; A 55-year-old man with tracheoesophageal fistula due to the esophageal cancer was scheduled for the stent placement. Anesthesia was given with dexmedetomidine and sevoflurane preserving spontaneous respiration. The surgery was performed without complications of hypoventilation and hypoxemia throughout the procedure. Case 2; A 71-year-old woman developed empyema with large bronchopleural fistula as the result of the complication of radiation for the breast cancer. The stent placement was scheduled for closure of the fistula. Anesthesia was induced with remifentanil and sevoflurane with spontaneous respiration. When inserting the rigid bronchoscope, cough reflex occurred and propofol was added to deepen the anesthesia. The stent placement was performed with general anesthesia under spontaneous respiration without any complications.

Successful exclusion of a large bronchopleural fistula using an Amplatzer II vascular plug and glue embolization

We report a case of a 63-year-old man with a complicated postsurgical bronchopleural fistula (BPF), which was treated with a minimally-invasive hybrid procedure using fluoroscopy, bronchoscopy, and thoracoscopy. A previous surgical attempt had failed to seal the pathologic tract. An Amplazter II vascular plug was successfully deployed into the BPF, followed by autologous blood and glue injection. An adjunctive endoscopically-guided glue embolization was deemed necessary. The 14-month clinical and imaging follow-up confirmed the successful exclusion of the BPF. No migration of the device was noted and the patient remained asymptomatic. The combined endoscopic and fluoroscopic guided management of a BPF using the Amplatzer II vascular plug and glue was proven safe and effective after mid-term follow-up.

Gastrobronchial fistula after sleeve gastrectomy and gastric bypass: endoscopic management and prevention

Gastrobronchial fistula (GBF) is a serious complication following bariatric surgery, whose treatment by thoracotomy and/or laparotomy involves a high morbidity rate. We present the outcomes of endoscopic management for GBF as a helpful technique for its healing process. This is a multicenter retrospective study of 15 patients who underwent gastric bypass (n = 10) and sleeve gastrectomy (n = 5) and presented GBF postoperatively (mean of 6.7 months). Ten patients developed lung abscess and were treated by antibiotic therapy (n = 10) and thoracotomy (n = 3). Abdominal reoperation was performed in nine patients for abscess drainage (n = 9) and/or ring removal (n = 4) and/or nutritional access (n = 6). The source of the GBF was at the angle of His (n = 14). Furthermore, 14 patients presented a narrowing of the gastric pouch treated by 20 or 30 mm aggressive balloon dilation (n = 11), stricturotomy or septoplasty (n = 10) and/or stent (n = 7). Fibrin glue was used in one patient. We performed, on average, 4.5 endoscopic sessions per patient. Endotherapy led to a 93.3% (14 out of 15) success rate in GBF closure with an average healing time of 4.4 months (range, 1-10 months), being shorter in the stent group (2.5 × 9.5 months). There was no recurrence during the average 27.3-month follow-up. A patient persisted with GBF, despite the fibrin glue application, and decided to discontinue it. GBF is a highly morbid complication, which usually arises late in the postoperative period. Endotherapy through different strategies is a highly effective therapeutic option and should be implemented early in order to shorten leakage healing time.

[Optimization of treatment methods of surgical complications in lung cancer]

The present report analyses the immediate and long-term results of treatment of surgical complications in 998 patients with lung cancer. There were complications in 37,5% of the cases, with a fatality rate of 14,7%. The most frequent complications were as follows: postoperative empyema with bronchopleural fistula (41,3%), bleeding (12,0%), pneumonia (9,8%), pulmonary arteries embolism (8,1%) and heart rhythm disorders (8,1%). Adjuvant and neoadjuvant treatment does not increase the rate of surgical complications as compared to just surgery alone (p = 0,1). Postoperative empyema with bronchopleural fistula requires intensive therapy, affects the quality of life of patients but does not decrease survival rates as compared to patients at the same stages of disease with uncomplicated course (p = 0,001). Timely drainage of pleural cavity accompanied by its adequate sanation does not differ (p = 0,1) from usage thoracoplasty (MS 29,9 months to 33,2 months).

[A case of chronic tuberculous empyema with a fistula treated with an endobronchial Watanabe spigot before surgery]

A 78-year-old man was referred to our hospital because of pyrexia in October 2008. Chest X-ray films and chest computed tomography (CT) indicated chronic tuberculous empyema in the right hemithorax. His general condition was not improved by antibiotic treatment, and CT showed pyothorax with a niveau and bronchial fistulas in May 2009. We subsequently performed open window thoracostomy and decortication of the residual dead spaces, but the bronchial fistulas remained. As this approach makes it difficult to ensure the sterility of the cavity, we therefore performed fiberoptic bronchoscopy and occluded the bronchus with an endobronchial Watanabe spigot (EWS). However, the bronchial fistula recurred, and therefore we performed this treatment again. We continued to carefully wash the cavity and the leakage stopped, whereupon the cavity became sterile. We then performed omental pedicle and muscle flap closure and thoracoplasty in April 2010. The empyema was cured without any complications. These findings suggest that using an EWS before surgery can be highly effective in controlling chronic tuberculous empyema with fistulas.

[Bronchobiliary fistulae as a complication of hepatic cystic echinococcosis]

Cystic hydatid disease or cystic echinococcosis (CE) rarely occurs in the Czech Republic. In 2005 - 2009, eleven cases were recorded, mostly among immigrants from the Balkans. Presented here is a case report of a 38-year-old patient with hepatic CE complicated by bronchobiliary fistulae. Ten days before surgical removal of the hydatid cysts, treatment with mebendazole was started. During surgery the affected part of the lungs was resected and the liver cysts were drained using transthoratic access. The follow-up was complicated by leakage of bile into the pleural cavity. The leakage was associated with continued communication between the liver cyst and the pleural cavity which did not close spontaneously after removal of the drain. Endoscopic nasobiliary drainage decreased pressure in the bile duct and within 14 days, it led to the spontaneous closure of the communication between the liver cyst and the pleural cavity. Seven months after the operation, the patient was in a very good clinical condition.

[Usefulness of esophageal stenting by using a covered self-expandable metallic stent for esophagorespiratory fistula associated with esophageal carcinoma]

We report three cases of esophagorespiratory fistula associated with esophageal carcinoma successfully treated with esophageal stenting by using a covered self-expandable metallic stent (SEMS). All three cases had advanced esophageal carcinoma at middle thoracic esophagus with esophagorespiratory fistula at the level of esophageal carcinoma. Case 1 is a 58-year-old man who had lung abscess due to esophagopulmonary fistula caused after induction chemoradiotherapy. He underwent a surgical resection of the affected lung and intraoperative esophageal stenting with dietary intake starting on day 26 after stenting. Case 2 is a 60-year-old man with esophagopulmonary fistula caused after primary chemotherapy. He started to take an oral intake on day 3 after esophageal stenting. Case 3 is a 68-year-old man with esophagobronchial fistula detected at the first medical examination. He started to take an oral diet on day 7 after esophageal stenting. All three cases had a rapid improvement of respiratory symptoms, pneumonia and malnutrition by esophageal stenting leading to marked improvement of impaired general condition. Esophageal stenting is a useful method for palliation of esophageal carcinoma with respiratory fistula.

Bronchoscopic management of bronchopleural fistula

In recent years successful bronchoscopic management of bronchopleural fistulas (BPFs) by locating its site and then blocking the leaking segment with any of the several agents available has gained recognition. It is now considered as an alternate mode of management of BPF. Here we present a case of non-resolving pneumothorax that was managed successfully using bronchoscopic glue (cyanoacrylate glue) instillation.

Endovascular treatment of aortobronchial fistula secondary to coronary artery bypass graft (CABG)

Aortobronchial fistula (ABF) is a rare and late complication of cardiac surgery. If untreated, mortality rate is approximately 100% secondary to exsanguinations haemoptysis. Early diagnosis and treatment are essential for successful management. Open surgical repair is associated with high morbidity and mortality rate, ranging from 25% to 41%. Endovascular treatments of ABF is a less invasive treatment modality and have become an important alternative to open surgical intervention in aortic pathologies. We present a case of ABF that successfully is managed by endovascular approach.

Aorto-oesophageal and aortobronchial fistulae following thoracic endovascular aortic repair: a national survey

OBJECTIVE

We evaluated the incidence of aorto-oesophageal (AEF) and aortobronchial (ABF) fistulae after thoracic endovascular aortic repair (TEVAR), and investigated their clinical features, determinants, therapeutic options and results.

METHODS

We conducted a voluntary national survey among Italian universities and hospital centres with a thoracic endovascular programme.

RESULTS

Thirty-nine centres were contacted, and 17 participated. Of the patients who underwent TEVAR between 1998 and 2008, 19/1113 (1.7%) developed AEF/ABF. Among indications to TEVAR, aortic pseudo-aneurysm was associated with the development of late AEF/ABF (P = 0.009). Further, emergent and complicated procedures resulted in increased risk of AEF/ABF (P = 0.008 and P < 0.001, respectively). Eight patients were treated conservatively, all of whom died within 30 days. Eleven patients underwent AEF/ABF surgical treatment, with a perioperative mortality of 64% (7/11). At a mean follow-up of 17.7 +/- 12.5 months, overall survival was 16% (3/19).

CONCLUSIONS

The incidence of AEF and ABF following TEVAR is not negligible, and is comparable to that following open repair. This finding warrants an ad hoc long-term follow-up after TEVAR, particularly in patients submitted to emergent and complicated procedures. Both surgical and endovascular treatment of AEF/ABF are associated with high mortality. However, conservative treatment does not appear to be a viable option.

Thoracobiliary fistula. A rare complication of thoracoabdominal trauma

Thoracobiliary fistulas (bronchobiliary and pleurobiliary) are rare complications of thoracoabdominal trauma. Owing to their rarity, there is little consensus on the optimal management . The diagnostic suspicion however must be considered and it's important the correct selection of diagnostic imaging techniques. Biliptysis is the pathognomonic physical finding of bronchobiliary fistulas. Demonstration of high bilirubin levels in the pleural effusion is diagnostic for a pleuro-biliary fistula. The optimal treatment of bronchobiliary fistulas is operative, in order to prevent their dramatic consequences. For pleurobiliary fistulas, a light aggressive conservative approach is an appealing option in the beginning. Newer endoscopic techniques increase the non-operative approach.

Closure of pneumonectomy stump fistula using custom Y and cuff-link-shaped silicone prostheses

Large postpneumonectomy stump fistulas pose a significant problem for thoracic surgeons and interventional bronchoscopists. We present a case of successful rigid bronchoscopic repair of a complete right pneumonectomy stump dehiscence using a custom-built stent made of a sculpted silicone Y stent sutured to a new cuff-link-shaped DJ-Fistula stent. This resulted in rapid symptom resolution, weaning from mechanical ventilation and discharge home in a patient with bronchogenic carcinoma, respiratory failure, and significant other comorbidities that precluded repeat thoracotomy.

Iatrogenic bronchopleural fistula occuring during redo cardiac surgery

Cardiac re-operations are associated with increased morbidity and mortality rates due to adhesion of tissues in the anterior mediastinum. Especially, previous usage of left internal thoracic artery constitutes a major challenge for cardiovascular surgeons. In such cases, the left lung frequently adheres to the thoracic wall and may be injured during dissection. This leads to air leak and the complication may in turn increase the risk of mediastinal infections and the hospital stay. A bronchopleural fistula case treated by a novel technique is reported. In patient iatrogenic bronchopleural fistula occured during dissection of the adhesions which resulted due to the first coronary artery bypass grafting and left internal thoracic artery usage. The air leakage was successfully controlled and treated by a novel method: self adhesive BioGlue immersed and coated Surgicel patch. Although it is a single case experience it may be a promising method as it is less traumatic when compared to the classical treatment methods of bronchopleural fistula.
