Research progress in the pathogenic mechanisms and imaging of severe frostbite

PurposeThis article reviews the pathological mechanisms and progress of imaging severe frostbite to assist in search for targets clinical diagnosis treatment frostbite. This review also aims provide strong evidence deep frostbite.MethodsThe was based on summary analysis existing literature, explored mechanism advantages disadvantages diagnostic methods.ResultsAccording depth tissue involvement, is divided into 4 levels. Severe includes Grade 3 Clinical performance evaluation research have always been mainstream diagnosis. Imaging methods focus vascular patency vitality. introduces angiography, SETCT/CT MRA, we summarize these methods. We recommend corresponding modalities according state patients.ConclusionsImaging examination, especially angiography bone scans, useful information determining prognosis In order obtain a good prognosis, clinicians should first perform SPECT/CT. MRA does not burden patient's body, but balance between cost benefit must be considered. Angiography provides feedback changes blood vessel status before after treatment, which helpful discovering response limbs treatment.
