ABSTRACT

PURPOSE@#Unstable pelvic fracture with bleeding can be fatal, with a mortality rate of up to 40%. Therefore, early detection and treatment are important in unstable pelvic trauma. We investigated the early predictive factors for possible embolization in patients with hemodynamically unstable pelvic trauma.@*METHODS@#From January 2011 to December 2013, 46 patients with shock arrived at a single hospital within 24 hours after injury. Of them, 44 patients underwent CT scan after initial resuscitation, except for 2 who were dead on arrival. Nine patients with other organ injuries were excluded. Seventeen patients underwent embolization. A single radiologist measured the width (longest length in axial view) and length (longest length in coronal view) of pelvic hematoma on CT scans. Demographic, clinical, and radiological data were reviewed retrospectively.@*RESULTS@#Among 35 patients with hemodynamically unstable pelvic fracture, 22 (62.9%) were men. Width (P = 0.002) and length (P = 0.006) of hematoma on CT scans were significantly different between the embolization and nonembolization groups. The predictors of embolization were width of pelvic hematoma (odds ratio [OR], 1.07; P = 0.028) and female sex (OR, 10.83; P = 0.031). The cutoff value was 3.35 cm. More embolization was performed (OR, 12.00; P = 0.003) and higher mortality was observed in patients with hematoma width >3.35 cm (OR, 4.96; P = 0.048).@*CONCLUSION@#Patients with hemodynamically unstable pelvic trauma have a high mortality rate. CT is useful for the initial identification of the need for embolization among these patients. The width of pelvic hematoma can predict possible embolization in patients with unstable pelvic trauma.

ABSTRACT

PURPOSE@#Patients with diffuse axonal injury experience various disabilities and have a high cost of treatment. Recent researches have revealed the underlying mechanism and pathogenesis of diffuse axonal injury. This study aimed to investigate the correlation between the radiological grading of diffuse axonal injury and the clinical outcomes of patients.@*METHODS@#From January 2011 to December 2016, among 294 patients with traumatic brain injury, 44 patients underwent magnetic resonance imaging (MRI). A total of 18 patients were enrolled in this study except for other cerebral injuries, such as cerebral hemorrhage or hypoxic brain damage. Demographic data, clinical data, and radiological findings were retrospectively reviewed. The grading of diffuse axonal injury was analyzed based on patient's MRI findings.@*RESULTS@#For the most severe diffuse axonal injury patients, prolonged intensive care unit (ICU) stay (p=0.035), hospital stay (p=0.012), and prolonged mechanical ventilation (p=0.030) were observed. However, there was no significant difference in healthcare-associated infection rates between MRI grading (p=0.123). Massive transfusion, initial hemoglobin and lactate levels, and MRI gradings were found to be highly significant in predicting the duration of unconsciousness.@*CONCLUSIONS@#This study showed that patients with high grade diffuse axonal injury have prolonged ICU stays and significantly longer hospital stays. Deteriorated mental patients with high energy injuries should be evaluated to identify diffuse axonal injuries by using an appropriate imaging tool, such as MRI. It will be important to predict the duration of consciousness recovery using MRI scans.
