Abstract:
A 36-year-old man suffered multiple traumatic injuries when he fell from a crane. Fractures of both lower extremities, a compression fracture of the fourth lumbar vertebra, and bilateral hemopneumothoraxes were identified. The sternum was not fractured, but was tender. The day after admission, the right ventricular free wall ruptured and was diagnosed by echocardiography. An emergency operation was performed. A Gore-tex sheet was sutured from inside the ventricle, and a Hemashield graft was sutured over the tear. The risk of hemorrhage is high in the patient with multiple traumatic injuries when heparin is required. Mechanical ventilation was required until the 13th postoperative day because persistent hemothorax. After an operation to reduce a leg fracture, the patient was discharged from the hospital on the 66th postoperative day.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
