RESUMO
Numerous diseases related to gastric distension have been found and shown to be linked with noninvasive positive pressure ventilation (NIPPV). We describe the case of a 93-year-old female who came with progressively worsening shortness of breath that initially responded to NIPPV but subsequently deteriorated. Imaging revealed gaseous distension of a preexisting hiatal hernia with air-fluid levels and compressive effects on the left lower lobe of the lung. She was successfully managed using a conservative decompression strategy. This is the first case to our knowledge of NIPPV causing considerable distension of an existing hiatal hernia to the point of mediastinal tamponade.
RESUMO
Coronavirus disease 2019 (COVID-19) and its spectrum of respiratory illnesses ranging from mild to severe and critically ill have been well established. Spontaneous pneumomediastinum and pneumopericardium (PP) appear to be less reported entities and have been found to be reported complications in COVID-19 infection. Pneumomediastinum (PM) and PP are characterized by the presence of air in the mediastinal and pericardial cavity, respectively. Although, generally, secondary to trauma or underlying lung conditions like asthma, bronchiolitis obliterans, and blunt trauma, it can also occur spontaneously without an evident primary cause. PM and PP are increasingly reported complications in COVID-19 patients adversely affecting clinical outcomes. We present a case series of patients with spontaneous pneumomediastinum and pneumopericardium in the presence of underlying COVID-19 infection and their management at our academic medical center.
