Delayed Presentation of Traumatic Pericardial Rupture: Diagnostic and Surgical Considerations for Treatment

Thoracoscopic diagnosis of traumatic pericardial rupture with cardiac hernia: A case report

BACKGROUND

Pericardial rupture caused by blunt chest trauma is rare in clinical practice. Because of its atypical clinical symptoms, and because surgeons are often unfamiliar with the clinical and radiological manifestations of the injury, preoperative diagnosis is difficult; it is easily misdiagnosed and causes serious consequences.

CASE SUMMARY

A 60-year-old man, previously healthy, was transported to the emergency room after falling from a great height. Upon arrival, his vital signs were stable. Electrocardiography and echocardiography were performed, and there was no sign of cardiac injury or ischemia. Chest and abdomen computerized tomography revealed pneumopericardium, hemopneumothorax, lung contusion, multiple rib fractures on the right side (Figure 1), and right scapula and clavicle fractures. He was admitted to the inpatient department for further observation after tube thoracostomy. The next day, the patient suddenly experienced rapid arrhythmia (the ventricular rate reached 150-180 beats/min) when turning onto his right side, accompanied by a blood pressure drop to 70/45 mm Hg and a chief complaint of palpitation. Thoracoscopy was performed urgently, and a large vertical tear (8 cm × 6 cm) was found in the pericardium. The defect was successfully repaired using a heart Dacron patch. His postoperative condition was uneventful without any fluctuations in vital signs, and he was transferred to the orthopedics department for further surgery on postoperative day 8.

CONCLUSION

Although the possibility of pericardial rupture combined with cardiac hernia is extremely low, it is one of the causes of cardiogenic shock following blunt trauma. Therefore, clinicians need to be more familiar with its characteristic manifestations and maintain a high degree of vigilance against such injuries to avoid disastrous consequences.

Pericardial injury after motor vehicle accident

Pericardial rupture is rare after blunt thoracic trauma and is associated with significant mortality. Mesh repair is recommended to prevent cardiac herniation and strangulation.
