Abdominal organs are the most vulnerable body parts under vehicle trauma, and there is high mortality from acute injuries in accidents. There are various ways to reduce this high mortality; one method is Resuscitative Endovascular Balloon Occlusion of the Aorta, which has recently become very popular as a minimally invasive alternative in the emergent management of patients with non-compressible hemorrhages below the diaphragm. However, high safety factor for patients is applied in actual clinical practice because there is no exact standard for the operating time. Therefore, in this study, the effects of the mechanical behavior of organ tissues for the duodenum, kidney, and liver on the operating time of Resuscitative Endovascular Balloon Occlusion of the Aorta is investigated in order to obtain data needed to establish standards of operating time. In characteristic analysis of organ tissues, uniaxial tensile test and compression test are conducted according to the operating time.

Paratracheal air cysts are rare lesions and detected incidentally during CT scan or autopsy. Histopathologic diagnoses of paratracheal air cysts include trachocele, tracheal diverticulum and lymphoepithelial cyst. The cysts are lined by ciliated columnar epithelium and have communication with trachea. Previous reports suggested an association with obstructive lung disease because of increased expiratory pressures in these patients. Most of these cysts are asymptomatic but rarely cause productive cough, wheezing, recurrent laryngeal nerve paralysis and difficult intubation. We report a case of paratracheal air cyst causing dyspnea with a review of literature.
