Cholecystopleural fistula with cholelithiasis presenting as a right pleural effusion

At autopsy, multiple gallstones were recovered from the right pleural space of an elderly patient who presented with a massive right pleural effusion and septic shock. The mechanisms of gallstone migration and fistula formation between the gallbladder and right pleural space are described. Despite atypical presentations, gallbladder disease remains an important differential consideration of right pleural effusion in the elderly.     

Spontaneous circumferential intramural esophageal dissection complicated with esophageal perforation and esophageal‐pleural fistula: a case report and literature review

Spontaneous intramural esophageal dissection (IED) is a rare disease entity. There are few reports of spontaneous IED requiring surgical treatment. Hereby, we report a 37‐year‐old gentleman who was diagnosed to have spontaneous extensive circumferential IED complicated with esophageal perforation, empyema, and esophageal‐pleural fistula. Esophageal stenting and drainage of empyema were unsuccessful. Computed tomography and gastrografin contrast swallow demonstrated a leak to the pleural cavity, suggestive of esophageal‐pleural fistula. Subsequently, a two‐stage operation was performed: cervical esophagogastrostomy to bypass the perforated esophagus, followed by esophagectomy and decortication of the right lung. The patient recovered and was discharged home after a 3‐week hospitalization. The management principles and recent published literature related to IED were reviewed.     

Aortopulmonary Artery Fistula: Ruptured Aneurysm of the Distal Aortic Arch into the Pulmonary Artery

Aortopulmonary artery fistula is uncommon, but the clinical outcome is often lethal. A 76‐year‐old man with a history of acute thoracic aortic dissection 6 years previously was admitted with dyspnea. A chest x‐ray showed pleural effusion and pulmonary congestion. Transthoracic echocardiography revealed preserved systolic function, but continuous and abnormal flow from the distal aortic arch into the pulmonary artery (PA). Transesophageal echocardiography (TEE) in the Doppler color‐flow mode demonstrated a left‐to‐right shunt between a large distal aortic arch aneurysm and the left PA via an aortopulmonary fistula and a pressure gradient across the shunt of 56 mmHg. Contrast‐enhanced computed tomography showed that the aneurysm compressed the PA. Aortography also revealed a large distal aortic arch aneurysm and almost simultaneous contrast enhancement of the aorta and the PA. Right‐heart catheterization showed a significant increase in oxygen saturation between the right ventricle and the PA. A left‐to‐right shunt due to a distal aortic arch aneurysm rupturing into the left PA was diagnosed based on these findings. TEE was very helpful in confirming the presence and precise location of the fistula.     

Intrapleural rupture of an pulmonary arteriovenous fistula]

We describe a case of intrapleural rupture of pulmonary arteriovenous fistula and review is such cases previously reported in Japan. A 57-year-old woman was admitted with a sudden onset of right chest pain. Chest radiograph on admission showed right pleural effusion. Thoracentesis revealed hemothorax and subsequently the patient complained of dizziness and went into shock. Chest CT scan revealed a well-defined nodule with a continuous enlarged vessel. Enhanced CT findings suggested a diagnosis of pulmonary arteriovenous fistula projecting into the intrapleural space from the right lower lung. Partial resection of the right lower lung was performed and the histological study confirmed the final diagnosis.     

A rare case of hemothorax due to rupture of an arteriovenous fistula: successful treatment by enucleation]

Hemothorax due to a rupture in an arteriovenous fistula is rare. We report a case in a 26-year-old woman who presented with continuous right chest pain. On admission, chest radiography revealed a nodular shadow in the right lower lung field with right pleural effusion. The pleural effusion aspirated was blood, suggesting a hemothorax due to the rupture of a pulmonary arteriovenous fistula. The shunt between A 8 and V 8 was confirmed in pulmonary arteriograms. A photomicrograph of the resected specimen showed a dilated arteriovenous fistula, part of whose inner wall was abnormally thin. The pleural wall surrounding the fistula was hypertrophic in parts, suggesting possible repetitive inflammation related with the rupture. Although transcatheter embolization is useful in the treatment of arteriovenous fistulae, it is technically difficult, and cases of fatal complications have been reported. While surgical resection is the most reliable treatment available, the present patient was already at high risk of dying. Accordingly, we chose to perform enucleation, and this was successful.     

Late esophagopleural fistula after left pneumonectomy: report on one case

Esophagopleural fistula is an uncommon complication of pneumonectomy. Late nonmalignant esophagopleural fistula after left pneumonectomy for lung cancer is exceedingly uncommon. We report on one patient who developed such a fistula 33 months after the operation. Signs and symptoms were first attributed to infection of the thoracotomy incision and diagnosis was made only after detection of some food coming from the pleural space. Thoracostomy, enteral feeding by a percutaneously placed gastrostomy tube and myoplasty allowed both closure of the fistula and obliteration of the pleural space.     

Left hepatic duct injury and thoracobiliary fistula after abdominal blunt trauma

Thoracobiliary fistula after blunt hepatic trauma is rare. We report a case of pleurobiliary fistula after a blunt hepatic trauma leading to a left hepatic lobe laceration together with a left hepatic duct injury. The management of this traumatic lesion is discussed and related to the existing literature data. The diagnosis of traumatic thoracobiliary fistula rests upon clinical suspicion in the setting of a persistent right pleural effusion. Demonstration of the presence of bile in the pleural cavity by thoracocentesis is considered a proof of pleural biliary fistula. We think that laparotomy is an appropriate route for the treatment of pleurobiliary fistulas. However, when a bronchobiliary fistula is suspected, the patient should be treated with thoracotomy and may require pulmonary resection to remove the fistulous tracts.     

A case of chronic pancreatitis complicated by massive pericardial and right pleural effusion

A 42-year-old man was admitted complaining of dyspnea. Chest X-ray showed an increase in cardiac size, and echocardiography revealed a large volume of pericardial effusion. Pancreatic enzyme levels were elevated in both serum and pericardial effusion. Computed tomography and endoscopic retrograde pancreatography demonstrated a fistula connecting a pancreatic pseudocyst with the pericardium and the right pleural cavity. Massive pericardial and right pleural effusion is an extremely rare complication of chronic pancreatitis. In this case, computed tomography and endoscopic retrograde pancreatography were useful for diagnosing the fistula.     

A case of pulmonary amebiasis

A 57-year-old man was admitted to our hospital because of dyspnea and right abdominal pain. Chest X-ray radiogram showed right massive pleural effusion. Ultrasonic echogram of abdomen showed a unilocular liver cyst. He was treated with intravenous infusion of meropenem, and percutaneous pleural and liver drainage were performed. At the time of drainage, we injected contrast medium into the liver cyst and confirmed a fistula connecting to the right pleural space. Initially we made a diagnosis of bacterial empyema and liver abscess, yet there was no response to the initial treatment. Cultures of pleural effusion and liver abscess were confirmed to be negative. A few days after admission, the patient stated that he was a homosexual. Liver amebiasis and its perforation became the most likely diagnosis, and metronidazole was administered. On admission day 21, tests for anti-amebic antibody were positive. Finally he fully recovered. We must be aware of the rare pulmonary manifestation of amebiasis. We report this case and review the literature.     

Intrapleural haemorrhage complicating pulmonary arteriovenous fistula

Rupture of a pulmonary arteriovenous fistula caused intrapleural haemorrhage in a young woman with hereditary haemorrhagic telangiectasia and multiple bilateral fistulas. Bleeding was limited and exsanguination was probably prevented by pleural adhesions. Treatment included decortication, excision of the bleeding fistula, and prophylactic sclerosis of the opposite pleural space.     

Postpneumonectomy empyema

Empyema is a serious complication after pneumonectomy. It is often associated with a bronchopleural fistula. Several risk factors have been associated with an increased incidence of these two challenging complications. Therapy aims at simultaneously treating the infected pleural space and the fistula. The authors describe their favorite methods which include repeated open debridements of the pleural space, primary closure of the fistula, and covering of the bronchial stump using intrathoracic transposition of extrathoracic skeletal muscle followed by delayed closure of the chest wall after instillation of an antibiotic solution (Clagett and modified Clagett procedures). The goals of treatment remain a healthy patient with a healed chest wall and no evidence of drainage or infection. Excellent results can be obtained in more than 80% of patients. Failure is often associated with a persistent or recurrent bronchopleural fistula.     

Bronchopleurobiliary fistula. A complication of intrahepatic biliary stent migration

We describe the management of bronchopleurobiliary fistula in a 56-year-old woman who underwent a (L) mastectomy with postoperative radio- and chemotherapy for advanced breast carcinoma and required insertion of inhabiliary Silastic stents for the relief of severe obstructive jaundice. During restaging of her carcinoma for further chemotherapy, she complained of dyspnea, right chest pain and productive cough with yellow sputum. Her chest x-ray film and thoraco-abdominal CT scan demonstrated right pleural effusion with a stent protruding through the right hemidiaphragm. The objective evidence of bile in the pleural aspirate with history of bile-stained sputum established the diagnosis of bronchopleurobiliary fistula resulting from biliary stent migration.     

A pancreatico-bronchial fistula with right hydropneumothorax

A 39-year-old heavy drinker was admitted to Saga Medical School Hospital on February 21th, 1987. He had suffered from dyspnea, chest pain and lumbago three weeks prior to admission. His chest X-ray showed right hydropneumothorax and right lower lobe atelectasis and his CT scan showed a cystic lesion in the mediastinum. His laboratory data showed a high level of amylase in serum, urine and pleural effusion. A fistula connecting the pancreas to right pleural cavity was demonstrated by endoscopic retrograde cholangiopancreatography (ERCP). In addition, bronchoscopy showed complete obstruction of the right lower bronchus (B7). These bronchoscopic findings and hydropneumothorax on his chest X-ray suggested the leakage of pancreas juice through the pancreatico-pleural fistula injured the lung tissue directly and produced a bronchopleural fistula. In this case, hyperalimentation and drug therapy using protease inhibitor resulted in successful closure of the fistula and reexpansion of the collapsed lung.     

Pancreatic Pleural Fistula: Demonstration by Computed Tomography after Endoscopic Retrograde Pancreatography

A case of chronic pancreatic pleural effusions is reported. The effusions were massive in the right chest at first and became bilateral. Endoscopic retrograde pancreatography showed a pancreatic pleural fistula toward the diaphragm. Computed tomography after endoscopic retrograde pancreatography revealed the entire course of the fistula and a mediastinal pseudocyst. Computed tomography and the operative fistulogram did not show immediate leakage of the contrast medium from the mediastinal pseudocyst.     

Postoperative residual pleural spaces: characteristics and natural history

This study was conducted in order to re-define the incidence and natural history of postresectional residual pleural spaces (PRS). From 1997 to 2005, 966 patients who were subjected to less than entire lung resections, were followed and any cases of PRS were recorded. The records of these patients were retrospectively analyzed for age, gender, type of resection, side, apical or basal location, size, PRS wall thickness, empyema as well as for bronchopleural fistula occurence, management, and outcome. Postresectional residual pleural spaces outcome was correlated with space characteristics. A total of 92 cases (9.5%) of PRS were documented which developed frequently ( p < 0.001) after upper lobectomies, malignant disease, at an apical location, and on the right side. Unfavorable outcome was strongly correlated with age > 70 years ( p < 0.001), air leak ( p < 0.001), empyema ( p < 0.001), and thickened pleura ( p < 0.001). Good prognosis of PRS was strongly correlated with male gender, apical location, right side, normal pleura thickness, and small size. Postresectional residual pleural spaces of small size without any associated complications should not prolong hospitalization time.     

Pancreatic pleural effusion accompanied by bronchopleural fistula]

In recent years, chronic massive pleural effusions have been increasingly recognized as a serious complication of pancreatitis. We describe the third reported case of a pancreatic pleural effusion accompanied by bronchopleural fistula. A 49-year-old man suffering from chronic alcohol-related pancreatitis was admitted to our hospital complaining of cough and shortness of breath. A chest x-ray film disclosed a large right pleural effusion with an air-fluid level. Ultrasonography and computed tomography of the upper abdomen demonstrated a giant pancreatic pseudocyst in the pancreatic tail and a fistulous tract reaching into the posterior mediastinum via the esophageal hiatus. Thoracentesis revealed sterile hemorrhagic fluid with markedly elevated amylase activity of 20,955 IU/l (pancreatic isozyme, 100%) and no malignant cells. A diagnosis of pancreatic pleural effusion was made. The therapy for pancreatic internal fistula is somewhat controversial. We employed conservative therapy, including hyperalimentation and chest tube drainage that successfully decreased the pleural effusion and closed the fistulous tract. Nonetheless, we were still troubled by a continuous air-leak via the drainage tube. Pleurodesis confirmed the tentative diagnosis of bronchopleural fistula and successfully stopped the air-leak. No re-accumulation of pleural effusion has been seen for 2 years. We concluded that pancreatic enzyme-rich effusions, if long-standing, may be complicated by bronchopleural fistula, thus underscoring the need for urgent drainage and initially conservative management.     

Percutaneous closure of acute aorto‐right ventricular fistula following transcatheter bicuspid aortic valve replacement

We report a case of acute aorto‐right ventricular fistula following transcatheter bicuspid aortic valve replacement and subsequent percutaneous closure. The diagnosis and treatment of this rare complication is illustrated through multi‐modality imaging. We hypothesize that the patient's heavily calcified bicuspid aortic valve anatomy led to asymmetric deployment of the transcatheter aortic valve replacement (TAVR) prosthesis, traumatizing the right sinus of Valsalva at the distal edge of the TAVR stent and ultimately fistulized to the right ventricle. The patient acutely decompensated with heart failure five days after TAVR and underwent emergent intervention. The aorto‐right ventricular fistula was closed using an 18‐mm septal occluder device with marked clinical recovery. Transcatheter closure is a viable treatment option for acute aorto‐right ventricular fistula. © 2016 Wiley Periodicals, Inc.     

Tuberculous empyema

Tuberculous empyema represents a chronic, active infection of the pleural space that contains a large number of tubercle bacilli. It is rare compared with tuberculous pleural effusions that result from an exaggerated inflammatory response to a localized paucibacillary pleural infection with tuberculosis. The inflammatory process may be present for years with a paucity of clinical symptoms. Patients often come to clinical attention at the time of a routine chest radiograph or after the development of bronchopleural fistula or empyema necessitatis. The diagnosis of tuberculous empyema is suspected on computed tomography imaging by finding a thick, calcific pleural rind and rib thickening surrounding loculated pleural fluid. The pleural fluid is grossly purulent and smear positive for acid-fast bacilli. Treatment consists of pleural space drainage and antituberculous chemotherapy. Problematic treatment issues include the inability to re-expand the trapped lung and difficulty in achieving therapeutic drug levels in pleural fluid, which can lead to drug resistance. Surgery, which is often challenging, should be undertaken by experienced thoracic surgeons.     

A case of Aspergillus empyema with bronchopleural fistula

Pleural aspergillosis is not a common disease and we recently experienced a case of Aspergillus empyema with bronchopleural fistula. A 76 year-old man was admitted to our hospital with productive cough and fever. Chest X-ray films showed infiltration in the right lower and left middle field and rather lucent area (clearing) in the right lower lung. Antibiotic therapy was administered but no improvement was obtained. Chest CT scan and right bronchography revealed empyema in the right back portion and bronchopleural fistula in the right lower lobe. Needle aspiration biopsy was performed and Aspergillus fumigatus was isolated from pus. A diagnosis of Aspergillus empyema with bronchopleural fistula was made. We began intrapleural administration of miconazole and empyema was improved partially. For the complete treatment, right lower lobectomy and decortication were performed, but unfortunately he died of acute pneumonia 16 days after operation.     

Massive pleural effusion as the presenting feature of a subarachnoid-pleural fistula

A 14-year-old boy presented with a large symptomatic transudative pleural effusion 4 months after spinal surgery for kyphoscoliosis. Computed tomography myelography confirmed a subarachnoid-pleural fistula (SPF) with a pseudo-meningocele communicating with the left pleural space. A review of the literature indicates this to be a rare finding. The possibility of SPF should be entertained in patients who present with a pleural effusion following transthoracic spinal surgeries.
