Isolated pericardial rupture with left-sided haematothorax after blunt chest trauma

Isolated tear in left atrial appendage due to blunt trauma chest: A rare case report

Blunt traumatic cardiac rupture is associated with a high mortality rate. Motor vehicle accidents account for most cardiac ruptures, but crush injury is relatively rare. We describe a case of a 72-year-old man who had the left atrial appendage ruptured through blunt trauma due to a fall from scooter. Simple suture repair of the atrial appendage was achieved after clamping the base of the left atrium to control the bleeding. He recovered without complication. Traumatic injury to left atrial appendage is rarely seen and reported.

Traumatic pericardial rupture without cardiac injury

Pericardial rupture is a rare injury following blunt chest trauma. It is frequently fatal because of serious complications such as cardiac herniation and/or contusion. We report a case of traumatic pericardial rupture without cardiac injury, which was incidentally identified intraoperatively. A 63-year-old woman was transported to the hospital after sustaining blunt chest trauma from a motor vehicle accident. Radiographic workup demonstrated multiple fractures, pulmonary contusion, and hemopneumothorax. A chest tube was inserted, and persistent bleeding was observed. An exploratory thoracotomy was performed, and active pulmonary bleeding was controlled. Further exploration revealed major pericardial rupture without cardiac herniation or intrapericardial injury, which was repaired by a bovine pericardial patch. Her postoperative course was uneventful. It is usually difficult to make a diagnosis of pericardial rupture, and a misdiagnosis often leads to a fatal consequence. Therefore, an immediate surgical exploration is warranted if clinical and radiographic findings suggest the condition.

Prevalence of Delayed Hemothorax in Blunt Thoracic Trauma

Delayed hemothorax (DHTX) is rarely seen. On an 8-year retrospective analysis of blunt thoracic trauma (BTT), hemothorax (HTX) was diagnosed in 167 patients: 18 children, 113 adults, and 36 elderly. No statistical differences were seen in any age groups regarding Injury Severity Score (mean ISS, 30.54), critical care length of stay (CLOS, 9.0), and hospital LOS (HLOS, 11.21). Mortality rate was 18 per cent in adults and 28 per cent in elderly ( P value < 0.0001). HTX was acute in 160 and delayed in 7 patients. Two-thirds of HTX patients were males and 75 per cent had rib fractures. All of our DHTX patients were males (5 adults and 2 elderly) and had rib fractures. Acute HTX was seen in younger patients (43.3 vs 56.1 years, P value 0.46), with higher ISS (31.44 vs 14.43, P value < 0.001), CLOS (7.19 vs 3.0 days, P value 0.511) and HLOS (11.9 vs 11.6, P value 0.468). Mortality was 22.5 per cent in AHTX and none in DHTX. Eighty-six per cent of DHTX and 49 per cent of AHTX patients went home on discharge. DHTX was rare (5%) in the current report with lower ISS, HLOS, and no mortality. Patients with rib fractures should be watched for development of DHTX as timely diagnosis and treatment is essential for favorable outcome.

Rupture of Left Atrial Appendage and Pericardium Due to Blunt Trauma

A 37-year-old woman sustained a ruptured pericardium and two lacerations of the left atrial appendage in an automobile accident. Simple suture repair of the atrial appendage was achieved after clamping the base of the left atrium to control the bleeding.
