Purpose: This study analyzed the characteristics of unstable pelvic bone fractures associated with intra-abdominal solid organ injury. Methods: Medical records were retrospectively collected from January 2000 to December 2010 for patients with unstable pelvic bone fractures. Unstable pelvic bone fracture was defined as lateral compression types II and III, antero-posterior compression types II and III, vertical shear and combined type by young classification. Subjects were divided into two groups, with (injured group) and without (non-injured group) intra-abdominal solid organ injury, to evaluate whether the characteristics of the fractured depended on the presence of associated solid organ injury. Data included demographics, mechanism of injury, initial hemodynamic status, laboratory results, revised trauma score (RTS), abbreviated injury scale (AIS), injury severity score (ISS), amount of transfusion, admission to the intensive care unit (ICU), and mortality. Results: The subjects were 217 patients with a mean age of 44 years and included 134 male patients(61.8%). The injured group included 38 patients(16.9%). Traffic accidents were the most common mechanism of injury, and lateral compression was the most common type of fracture in all groups. The initial blood pressure was lower in the injured group, and the ISS was greater. The arterial pH was lower in the injured group, and shock within 24 hours after arrival at the emergency department was more frequent in the injured group. The amount of the transfused packed red blood cells within 24 hours was higher in the injured group than the non-injured group. Invasive treatment, including surgery and angiographic embolization, was more common in the injured group, and the stay in the ICU was longer in the injured group. Conclusion: A need exists to decide on a diagnostic and therapeutic plan regarding the possibility of intra-abdominal solid organ injury for hemodynamically unstable patients with unstable pelvic bone fractures and multiple associated injuries.

Interventional management is commonly used for traumatic injuries to the abdominal solid organs. The American Association for the Surgery of Trauma (AAST) and the World Society of Emergency Surgery (WSES) recently published guidelines for the management and treatment of liver, spleen, and kidney injuries, emphasizing the importance of interventions. Here, we discuss the characteristics of each organ and the procedure method for each organ that interventional radiologists need to know when treating trauma patients.

Enlargement of organs or other solid tissues usually presents as an abdominal mass. Often, abdominal masses in children are found by an unsuspected parent or by a physician during a routine examination. Most masses have no specific signs or symptoms. Abdominal masses in children require immediate attention. History and physical examination may provide clues to the diagnosis. Ultrasound examination is the most useful screening test in most cases and may identify the organ involved and clarify whether the mass is solid or cystic. CT may be necessary to make a more precise diagnosis, especially solid masses. MRI is occasionally is helpful for specific abnormalities.

Although many studies reported the safety and efficacy of high-intensity focused ultrasound (HIFU) therapy, there are still worries about internal organ injury. However, reports of abdominal wall hernias after HIFU therapy are rare. We present three cases of abdominal wall hernias without skin injury after HIFU therapy in uterine adenomyosis or fibroids. The diagnosis was often delayed because of vague symptoms, inadequate clinical suspicion, and delayed proper image studies. Abdominal wall hernia should be recognized as a possible complication after HIFU and be suspected when the patient presents with unordinary abdominal swelling and/or pain that lasts for more than a few months after the procedure.

The management of twenty-two children with blunt abdominal trauma was analyzed. Nineteen cases had intraabdominal injuries; involving the spleen in 7 cases, the liver in 5, the pancreas in one and the bladder in one. There were five case multiple intraabdominal organ injuries. Seventeen out of 19 patients were treated non-operatively, but one was operated upon later because of delayed bleeding. Thirteen patients required transfusion in the non operated group, the mean values of the Pediatric Trauma Score (PTS) was 11.3. The mean lowest hemoglobulin(LHb) was 9.1 g/dL. The mean value of three cases with extraabdominal injuries were 9.0 and 8.3 g/dL respectively. The average amount of transfusion was 17.3 ml/kg. In the operated group, 2 cases were transfused an average of 139.8 ml/kg and their mean PTS was 5 and LHb was 6.6 g/dL. In one out of 16 non-operated cases, intrahepatic hematoma developed and but resolved conservatively. However, two out of 3 operated cases suffer complications such as an intubation granuloma and an intraabdominal abscess with wound dehescence. In conclusion, non-operative management in child with blunt abdominal trauma was safe in Grade I and II solid organ injuries. The decision for operation should be based on the hemodynamic stability after initial resuscitation including transfusion.

Trauma is one of the leading causes of death in children. Abdominal trauma is about 10 % of all pediatric trauma. This study describes the sex and age distribution, injury mechanism, site of intraabdominal injury, management and mortality of children aged 16 years or less who suffered abdominal trauma. The hospital records of 63 patients treated for abdominal injury between March 1997 and February 2007 at the department of surgery, Inje University Pusan Paik Hospital, were analyzed retrospectively. The peak age of incidence was between 2 and 10 years (78%) and this report showed male predominance(2.7:1). The most common mechanism of blunt abdominal trauma was pedestrian traffic accident (49%). The most common injured organ was liver. More than Grade IV injury of liver and spleen comprised of 4(12%) and 5(24%), respectively. Fourteen cases (22%) had multiple organ injuries. Forty nine cases (78%) were managed nonoperatively. Three patients (4.8%) died, who had Grade IV liver injury, Grade IV spleen injury, and liver and spleen injury with combined inferior vena cava injury, respectively. All of the three mortality cases had operative management. In conclusion, the liver or spleen injury which was more than Grade 4 might lead to mortality in spite of operation, although many cases could be improved by nonoperative management.

Purpose: There is increasing interest in intra-abdominal pressure (IAP) and intra-abdominal hypertension (IAH) in critically ill patients. This study investigated the effects and outcomes of elevated IAP in a trauma intensive care unit (ICU) population. Methods: Eleven consecutive critically ill patients admitted to the trauma ICU at Pusan National University Hospital Regional Trauma Center were included in this study. IAP was measured every 8-12 hours (intermittently) for 72 hours. IAP was registered as mean and maximal values per day throughout the study period. IAH was defined as $IAP{\geq}12mmHg$. Abdominal compartment syndrome was defined as $IAP{\geq}20mmHg$ plus ${\geq}1$ new organ failure. The main outcome measure was in-hospital mortality. Results: According to maximal and mean IAP values, 10 (90.9%) of the patients developed IAH during the study period. The Sequential Organ Failure Assessment (SOFA) score was significantly higher in patients with $IAP{\geq}20mmHg$ than in those with IAP <20 mmHg (16 vs. 5, p=0.049). The hospital mortality rate was 27.3%. Patients with a maximum $IAP{\geq}20mmHg$ exhibited significantly higher hospital mortality rates (p=0.006). Non-survivors had higher maximum and mean IAP values. Conclusions: Our results suggest that an elevated IAP may be associated with a poor prognosis in critically ill trauma patients.

Dose monitoring in CT patients requires accurate dose estimation but most of the CT dose calculation tools are based on Caucasian computational phantoms. We established a library of organ dose conversion coefficients for Korean adults by using four Korean adult male and two female voxel phantoms combined with Monte Carlo simulation techniques. We calculated organ dose conversion coefficients for head, chest, abdomen and pelvis, and chest-abdomen-pelvis scans, and compared the results with the existing data calculated from Caucasian phantoms. We derived representative organ doses for Korean adults using Korean CT dose surveys combined with the dose conversion coefficients. The organ dose conversion coefficients from the Korean adult phantoms were slightly greater than those of the ICRP reference phantoms: up to 13% for the brain doses in head scans and up to 10% for the dose to the small intestine wall in abdominal scans. We derived Korean representative doses to major organs in head, chest, and AP scans using mean CTDI_vol values extracted from the Korean nationwide surveys conducted in 2008 and 2017. The Korean-specific organ dose conversion coefficients should be useful to readily estimate organ absorbed doses for Korean adult male and female patients undergoing CT scans.

Purpose: The appropriate management of traumatic truncal arterial injury is often difficult to determine, particularly if the injury is associated with severe additional truncal lesions. The timing of repair is controversial when patients arrive alive at the hospital. Also, there is an argument about surgery versus stent-graft repair. This study's objective was to evaluate the appropriate method and the timing for treatment in cases of truncal abdominal injury associated with other abdominal lesions. Methods: The medical records at Ajou University Medical Center were reviewed for an 8-year period from January 1, 2001, to December 31, 2008. Twelve consecutive patients, who were diagnosed as having had a traumatic truncal arterial injury, were enrolled in our study. Patients who were dead before arriving at the hospital or were not associated with abdominal organ injury, were excluded. All patients involved were managed by using the ATLS (Advanced Trauma Life Support) guideline. Data on injury site, the timing and treatment method of repair, the overall complications, and the survival rate were collected and analyzed. Results: Every case showed a severe injury of more than 15 point on the ISS (injury severity score) scale. The male-to-female ratio was 9:3, and patients were 41 years old on the average. Sites of associated organ injury were the lung, spleen, bowel, liver, pelvic bone, kidney, heart, vertebra, pancreas, and diaphragm ordered from high frequency to lower frequency. There were 11 cases of surgery, and one case of conservative treatment. Two of the patients died after surgery for truncal organ injury: one from excessive bleeding after surgery and the other from multiple organ failure. Arterial injuries were diagnosed by using computed tomography in every case and 9 patients were treated by using an angiographic stent-graft repair. There were 3 patients whose vessels were normal on admission. Several weeks later, they were diagnosed as having a truncal arterial injury. Conclusion: In stable rupture of the truncal artery, initial conservative management is safe and allows management of the major associated lesions. Stent grafting of the truncal artery is a valuable therapeutic alternative to surgical repair, especially in patients considered to be a high risk for a conventional thoracotomy.
