Abstract
BACKGROUND

Post-traumatic blunt pericardial injury is a rare condition with only a few reported cases which were generally diagnosed during initial examinations upon admission. However, pericardial injuries not bad enough to dislocate the heart may only cause intermittent electrocardiogram (ECG) changes or be asymptomatic.

CASE SUMMARY

In this case, we report a blunt pericardial injury undetected on preoperative transthoracic echocardiography and chest computed tomography. We misjudged intermittent ECG changes and blood pressure fluctuations as minor symptoms resulting from cardiac contusion and did not provide intensive treatment. The pericardial injury was found incidentally during surgical stabilization of rib fractures and was successfully repaired.

CONCLUSION

Post-traumatic blunt pericardial ruptures should be considered in patients with blunt chest trauma showing abnormal vital signs and ECG changes.

Core Tip: Post-traumatic blunt pericardial rupture is a rare but fatal injury that is usually diagnosed with computed tomography upon admission, but the condition can be asymptomatic or misdiagnosed. If a patient with blunt chest trauma shows fluctuating vital signs and accompanying electrocardiogram abnormalities, pericardial rupture and cardiac herniation should be considered.
