Case report of a 72-year-old man with diaphragmatic hernia and thoracic gastropericardial fistula after esophagectomy for 18 years.

BACKGROUND: Both diaphragmatic hernia and thoracic gastropericardial fistula rarely occur simultaneously in patients with radical esophagectomy. CASE PRESENTATION: A 72-year-old man presented to our hospital with 1 day of nausea, vomiting and acute left chest pain. He had radical esophagectomy (Sweet approach) for esophageal cancer 18 years ago. Computed tomography (CT) of the chest revealed diaphragmatic hernias and air collection within the pericardial space. While an operation of diaphragmatic hernia repair was decisively performed to prevent further serious complications, unusually, a thoracic gastropericardial fistula was also found unusually. CONCLUSION: Diaphragmatic hernia and thoracic gastropericardial fistula may occasionally coexist in patients with esophagectomy. Upper GI radiograph with a water-soluble contrast agent is a better diagnostic tool than CT in visualizing the fistula.

Pneumothorax leading to pneumopericardium after transvenous lead implantation in a patient with previous epicardial lead.

A 44-year-old lady, a follow-up case of idiopathic dilated cardiomyopathy and cardiac resynchronization therapy defibrillator device implantation with epicardial left ventricular (LV) lead, underwent a transvenous LV lead revision in view of epicardial lead malfunction. A chest X-ray after this, done for worsening dyspnea, revealed pneumopericardium along with left pneumothorax. The computed tomography (CT) revealed a communication between the left pleural and pericardial cavities, around the old epicardial lead. Drainage of the left pleural cavity resolved both the pneumothorax and pneumopericardium and the patient remained well on follow up.

Early Pneumopericardium after Endoscopic Thoracic Sympathectomy.

Pneumopericardium is a condition characterised by the presence of air within the pericardium. We hereby present a case of a rare potentially life-threatening complication, which is, to our knowledge, the first report of the pneumopericardium after single port endoscopic thoracic sympathectomy (SPETS). A 25-year male patient with a history of bilateral palmar hyperhidrosis underwent SPETS. Routine chest X-ray at post-anesthesia care unit showed presence of diffuse subcutaneous emphysema, helping to establish the diagnosis of pneumopericardium with no symptoms after the surgery.  Pneumopericardium should be considered among the possible complications of SPETS. Such complication may progress to a fatal event, if not recognised early and managed rapidly. Based on clinical experience, routine postoperative clinical follow-up protocols should be established and applied for each patient following SPETS. Key Words: Palmar hyperhidrosis, Endoscopic thoracic sympathectomy, Pneumopericardium.

[Thoracic endometriosis complicated with pneumopericard and iterative pneumothorax due to bullous dystrophy]. / Endométriose thoracique compliquée de pneumopéricarde et pneumothorax itératifs sur dystrophie bulleuse.

Thoracic endometriosis is a rare entity characterized by presence of endometrial tissue in pleura, lung parenchyma or airways. Most frequent manifestations are catamenial pneumothorax, hemothorax, hemoptysis and pulmonary nodules. We report here a rare case of a woman with thoracic endometriosis who developed iterative pneumothorax and pneumopericardium on bilateral bullous pulmonary dystrophy. She was a 37-year-old woman without any tobacco exposure and with previous history of pleural tuberculosis treated 5 years earlier. She was first referred to our centre for right pleuro-pneumothorax and hemorrhagic ascites. Pleural fluid examinations did not show any tuberculosis relapse, the evolution was favorable after thoracic drainage and there was no parenchymal lung abnormality on CT scan after surgery. Celioscopic peritoneal examination revealed stage IV peritoneal endometriosis. One year later, she was admitted for left catamenial pneumothorax. Thoracic CT scan showed apparition of large subpleural bulla. She underwent thoracotomy for bulla resection and left partial pleurectomy. Two years later, she was hospitalized for right pneumothorax and compressive pneumopericardium. Surgical lung biopsies confirmed pleuropulmonary endometriosis. Thoracotomy was performed for talcage pleurodesis and diaphragmatic leakages sutures. Lung bulla are rare in thoracic endometriosis, mechanism of their formation remains unknown. Pericardial involvement is rare in endometriosis; we report here a unique case of pneumopericardium.

Acute Delayed Tension Pneumopericardium: The First Reported Case After Elective Lobectomy.

Pneumopericardium is an overall rare condition caused by increased intrathoracic positive pressure. Different mechanisms can contribute to its development. It can be observed in both pediatric and adult populations. Only a small percentage of patients have cardiac tamponade. We describe the first case of delayed tension pneumopericardium after elective lobectomy. Sudden symptom onset and clinical management are discussed. Only an accurate and quick patient assessment allowed diagnosing this condition and, hence, its correct treatment. Although the diagnosis of pneumopericardium is uncommon, if untreated, it can be fatal.

Tension pneumopericardium in a multiply injured child.

Tension pneumopericardium is a rare disease that is very difficult to diagnose. A 3-year old child was run over by a minibus. Computed tomography showed bilateral pneumothorax, multiple rib fractures on both sides, and a hepatic laceration. The massive blunt thoracic trauma caused entrapped air in the pericardium, and a tension pneumoprecordium developed abruptly. We report this unique case of tension pneumopericardium in a child, and the subsequent emergency surgery and damage control measures.

A fatal complication of an incarcerated diaphragmatic hernia: pyo-pneumopericardium due to a gastro-pericardial fistula Case report and literature review.

INTRODUCTION: The pyo-pneumopericardium is a very rare complication of an incarcerated diaphragmatic hernia. Usually, it depends on the existence of a gastropericardial fistula and, in most cases, it is a deadly complication. CASE REPORT: We present the case of a 65 year old man who was admitted to our emergency service with clinical signs of septic shock. With the help of the CT scan a pyo-pneumopericardium and incarcerated diaphragmatic hernia was diagnosed. He was subjected to emergency surgical intervention with double approach (thoracic and abdominal), discerning during surgery the existence of a pericardial abscess due to a gastro-pericardial fistula due to an incarcerated diaphragmatic hernia. The gastric fundus was resected with abolition of the gastro-pericardial fistula, evacuation of the pericardial abscess, performing the splenectomy (in order to have a better surgical access) and adequate treatment of the diaphragmatic hernia. Despite the medical efforts, the patient died on the 10th postoperative day due to septic complications. To our knowledge this is the first case reported in the literature of gastro-pericardial fistula complicated with pyo-pneumo-pericardium due to an incarcerated diaphragmatic hernia. In such cases we consider that only by performing a double surgical approach (thoracic and abdominal) we can provide a proper resolution of the case, also based on the objective situation found during surgery, where the splenectomy can provide an easier approach to the diaphragmatic hernia. KEY WORDS: Diaphragmatic hernia, Gastropericardial fistula, Pyo-pneumopericardium.

Pneumopericardium: an uncommon complication of atrial lead perforation following pacemaker implantation.

Cardiac perforation is an infrequent but potentially life-threatening complication of pacemaker implantation. We report a case of right atrial lead perforation complicated by pneumopericardium shortly after pacemaker lead insertion. Transthoracic echocardiography revealed no evidence of pericardial effusion and pacemaker lead displacement, but a thoracic computed tomography scan illustrated the lead course and confirmed the diagnosis. This case suggests that computed tomography is a sensitive modality to confirm the diagnosis at the early stage of this complication.

Management of a pneumopericardium due to penetrating trauma.

INTRODUCTION: A pneumopericardium presenting after penetrating chest trauma is a rare event. The surgical management of this clinical problem has not been clearly defined. The aim of this study was to document the mode of presentation and to suggest a protocol for management. PATIENT AND METHODS: A review of a prospectively collected cardiac database of patients presenting to Groote Schuur Hospital Trauma Centre between October 2001 and February 2009 with a pneumopericardium on chest X-ray after penetrating trauma. RESULTS: There were 27 patients with a pneumopericardium (mean age 25 years, range 17-36). The mechanism of injury was a stab wound to the chest in 26 patients and a single patient with multiple low velocity gunshot wounds. Six patients (22%) were unstable and required emergency surgery. One of these patients presented with a tension pneumopericardium. Twenty-one patients were initially stable. Two of these (10%) patients later developed a tension pneumopericardium within 24-h and were taken to theatre. The remaining 19 patients were managed with a subxiphoid pericardial window (SPW) at between 24 and 48h post admission. Ten of these 19 patients (52%) were positive for a haemopericardium. Only 4 of the 19 underwent a sternotomy and only two of these had cardiac injuries that had sealed. There were no deaths in this series. CONCLUSION: Patients with a penetrating chest injury with a pneumopericardium who are unstable require emergency surgery. A delayed tension pneumopericardium developed in 10% of patients who were initially stable. It is our recommendation that all stable patients with a pneumopericardium after penetrating chest trauma should undergo a SPW. A sternotomy is not required in stable patients.

[Bronchopericardial fistula treatment by a metallic stent]. / Traitement d'une fistule bronchopéricardique par prothèse endobronchique métallique.

INTRODUCTION: Bronchopericardial fistula is a rare condition leading to pneumopericardium. This medical condition is often related to neoplastic disease, or a complication of surgical interventions. The treatment approach depends on both the etiology and the clinical presentation. In stable patients, pericardial drain insertion and/or surgical resection of the fistula are considered options for persistent cases. We present the case of a bronchopericardial fistula treated by placement of an endobronchial stent. CASE PRESENTATION: A 64-year-old man operated on for lung cancer had a recurrence treated with radiation and chemotherapy. A pneumopericadium was discovered when he presented with a new onset of atrial fibrillation. Bronchoscopy revealed a fistula tract. Pericardial drainage was persistent and did not improve the clinical situation. The poor health status of the patient contraindicated surgery and an alternative therapeutic approach with endobronchial stent placement was undertaken. The fistula sealed immediately, the pericardial drain could be removed removed and the patient was able to be discharged from hospital. CONCLUSION: Endobronchial stenting should be considered as a potential treatment option in patients with pneumopericardium secondary to bronchopericadial fistula, particularly where a non-surgical is required.

Intraoperative occurrence of a pneumopericardium during double-lung transplantation.

Pneumopericardium is rare and has been reported secondary to chest trauma. We report a case of tension pneumopericardium occurring during double-lung transplantation, where intraoperative transoesophageal echocardiography first showed a hypokinetic left ventricle and a few minutes later a compression of its anterolateral portion due to pneumopericardium. Although the pericardium was opened, left ventricular function remained depressed, necessitating extracorporeal membrane oxygenation, which was withdrawn after 48 h of assistance when left ventricular function had recovered. The patient was extubated on the seventh postoperative day but died of multiorgan failure on the 64 th postoperative day.
