ABSTRACT

INTRODUCTION: Pneumothorax and pneumomediastinum have both been noted to complicate cases of coronavirus disease 2019 (COVID-19) requiring hospital admission. We report the largest case series yet described of patients with both these pathologies (including nonventilated patients). METHODS: Cases were collected retrospectively from UK hospitals with inclusion criteria limited to a diagnosis of COVID-19 and the presence of either pneumothorax or pneumomediastinum. Patients included in the study presented between March and June 2020. Details obtained from the medical record included demographics, radiology, laboratory investigations, clinical management and survival. RESULTS: 71 patients from 16 centres were included in the study, of whom 60 had pneumothoraces (six with pneumomediastinum in addition) and 11 had pneumomediastinum alone. Two of these patients had two distinct episodes of pneumothorax, occurring bilaterally in sequential fashion, bringing the total number of pneumothoraces included to 62. Clinical scenarios included patients who had presented to hospital with pneumothorax, patients who had developed pneumothorax or pneumomediastinum during their inpatient admission with COVID-19 and patients who developed their complication while intubated and ventilated, either with or without concurrent extracorporeal membrane oxygenation. Survival at 28 days was not significantly different following pneumothorax (63.1±6.5%) or isolated pneumomediastinum (53.0±18.7%; p=0.854). The incidence of pneumothorax was higher in males. 28-day survival was not different between the sexes (males 62.5±7.7% versus females 68.4±10.7%; p=0.619). Patients aged ≥70 years had a significantly lower 28-day survival than younger individuals (≥70 years 41.7±13.5% survival versus <70 years 70.9±6.8% survival; p=0.018 log-rank). CONCLUSION: These cases suggest that pneumothorax is a complication of COVID-19. Pneumothorax does not seem to be an independent marker of poor prognosis and we encourage continuation of active treatment where clinically possible.

ABSTRACT

We present the case of a 22-year-old primigravida with symptoms of neck swelling and difficulty breathing 3 hours after uneventful vaginal delivery. On examination, there was surgical emphysema. A CT scan confirmed air in the subcutaneous tissues and also revealed pneumomediastinum. There was no evidence of pneumothorax and gastro-oesophageal endoscopy showed no signs of oesophageal rupture. The patient remained clinically stable throughout her admission and was discharged home after 48 hours of observation. Pneumomediastinum is one of the rare causes of shortness of breath and chest pain during the postpartum period, and it should be considered in the differential diagnosis. Despite the significant abnormalities seen on plain radiography and CT scan, this condition spontaneously resolves. Although postpartum pneumomediastinum has been related to prolonged labour, this was not the case in our patient.
