[Clinical study of multiple traumas with severe facial injury undergoing emergency endovascular treatment: significance of emergency embolization of the external carotid artery].

ABSTRACT

The outcome of multiple injures freqently depends on the priority of treatments, and the decision as to the procedures and timing of primary care is extremely important. We studied the patients with multiple trauma whounderwent emergency endovascular treatment for facial hemorrhage related to external carotid arterial injury. The subjects are 5 patients who underwent embolization of the external carotid artery by an endovascular approach among patients with multiple traumas who were brought to our hospital by ambulance. In these patients, the vital signs on arrival, interval between injury and intravascular surgery, type of brain injury, type and grade of concurrent injury and outcome were studied. Three patients showed hemorrhagic shock on arrival, and 1 patient showed hemorrhagic shock immediately after arrival. The mean interval between injury and endovascular surgery was 3.9 hours. All patients had skull base fracture, and abnormal intracranial lesions on initial CT including 4 focal injuries and 1 diffuse injury. Moderate to severe thoracic/abdominal injuries were noted in 3 patients. In the remaining 2 patients, there was no trauma in the thoracic or abdominal regions. Intraperitoneal hemorrhage with splenic injury was observed in 3 patients. In 3 of 4 patients died by hemorrhagic shock because of the delay of endvascular treatments. In trauma patients with persistent hemorrhage, emergency endovascular treatment should be considered as a primary survey for initial treatment without delay under intensive conservative treatment.
