CASE REPORT
A 65-year-old male veteran underwent a five-vessel CABG at the University Medical Center in Jackson, Miss. His postoperative course was complicated by prolonged mechanical ventilation. On the 7th postoperative day, he was extubated and placed on conventional face mask with 40%; FIo2 and intermittent CPAP of 5 cm H2O. On the 9th postoperative day, he was transferred back to the coronary care unit at the VA Medical Center in Jackson, Miss, for further postoperative management and observation.
DISCUSSION
Pneumopericardium, a form of barotrauma, refers to the presence of air within the pericardial sac, a condition that is much less common than either pneumothorax or pneumomediastinum. Pneumopericardium results from mediastinal air dissecting at the reflection of the parietal to visceral pericardium near the ostia of the pulmonary veins.6 This occurs more frequently in infants than in adults. This is probably due to the stronger adhesions between the pericardial layers in the adult, precluding

Pneumopericardium, pneumomediastinum and air travel: A case report in a patient with Gardner syndrome
2020, Respiratory Medicine Case ReportsCitation Excerpt :Pneumothorax is the more common thoracic emergency encountered during air travel [2]. Etiologies of pneumomediastinum and pneumopericardium are diverse and include trauma, post-procedural, elevated intra-thoracic pressures, pulmonary pathologies and occasionally unknown [3,4]. After reviewing the medical literature, two case reports of air travel causing air leaks around the heart or in the mediastinum have been reported to date.
A delayed case of tension pneumopericardium after total gastrectomy
2014, Journal of Clinical AnesthesiaCitation Excerpt :Subsequent pericardial tamponade is often life-threatening. Pneumopericardium is a complication of endotracheal intubation [1], laparoscopic surgery [2], and positive pressure ventilation (PPV) [3]. It has also been reported to develop after esophagectomy [4] and gastrectomy [5,6] in the postoperative chronic period.

2008, Journal of Thoracic and Cardiovascular SurgeryCitation Excerpt :Radiologic imaging via a chest x-ray or CT scan commonly identifies the presence of air in the pericardial cavity. Although pneumomediastinum and pneumopericardium are frequently confused because they can happen concomitantly, 3 signs on the chest x-ray can help to discriminate between them: 1) a radiolucent halo of air partially or completely surrounding the heart but not extending superiorly to the attachment of pericardium, 2) a shift in pericardial air on a decubitus radiograph, and 3) the absence of a continuous diaphragm.5 A chest CT scan is of paramount importance in the diagnosis of tension pneumopericardium.
Continuous Positive Airway Pressure for the Treatment of Sleep Apnea
2007, Otolaryngologic Clinics of North AmericaCitation Excerpt :Although machine noise was noted by 34% of patients in this study, it is probably less of a problem today with newer, quieter machines. There have been case reports of chest discomfort from the pressure, one case of pneumocephalus [45], a postcoronary artery bypass pneumopericardium [46], and one case report of meningitis related to recurrent sinusitis [47]. There are no absolute contraindications for CPAP use but bouts of recurrent acute sinusitis following CPAP use may be a relative contraindication [47].
