An X-ray picture of tension pneumopericardium, as a transsternal transpericardial main bronchus stump occlusion complication, not previously seen after this sur-gery, is described. The clinical picture of a tension pneumopericardium and diag-nostic methods applied to determine this condition are reported. Successful elimination of complications in a somatically burdened patient was possible only due to rapid and accu-rate diagnostics of this condition.
