Background: We report our 10-year experience with traumatic peripheral arterial injury repair at an urban level I trauma center. Methods: Between January 2007 and December 2016, 28 adult trauma patients presented with traumatic peripheral arterial injuries. Data were retrospectively collected on demographic characteristics, the mechanism of injury, the type of vascular injury, and physiological status on initial assessment. The analysis also included the Mangled Extremity Severity Score (MESS), Injury Severity Score, surgical procedures, and outcome variables including limb salvage, hospital stay, intensive care unit stay, and postoperative vascular complications. Results: Four (14.3%) patients required amputation due to failed revascularization. MESS significantly differed between patients with blunt and penetrating trauma (8.2±2.2 vs. 5.8±1.3, respectively; p=0.005). The amputation rate was not significantly different between patients with blunt and penetrating trauma (20% vs. 0%, respectively; p=0.295). The overall mortality rate was 3.6% (1 patient). Conclusion: Blunt trauma was associated with higher MESS than penetrating trauma, and amputation was more frequent. In particular, patients with blunt trauma had significantly higher MESS than patients with penetrating trauma (8.2±2.2 vs. 5.8±1.3, respectively; p=0.005), and amputation was performed when revascularization failed in cases of blunt trauma of the lower extremity. Therefore, particular care is needed in making treatment decisions for patients with peripheral arterial injuries caused by blunt trauma.
Two aged patients who had open tibial fractures with arterial injury caused by high energy accidents underwent emergency arterial reconstruction using a greater saphenous vein and soft tissue repair using free flaps. In the patients, soft tissue necrosis developed and tibias were exposed at postoperative third week. Follow-up angiography through the superficial femoral artery showed occlusion of the anterior tibial artery. The anterior tibial artery was reconstructed using the contralateral greater saphenous vein graft and the latissimus dorsi myocutaneous and rectus abdominis muscle free flaps were transplanted for repair of necrotic soft tissue. The reconstructed arteries showed good perfusion to the new free flaps until union of the tibias occurred. The patients were followed-up for 21 years and 17 years postoperatively, respectively. In management of open comminuted fracture of the tibia, injury of the arterial system must be ruled out by angiography in addition to evaluation of the degree of soft tissue injury.
Iatrogenic vascular injuries during lumbar disc surgery may occur rarely but they are serious complications, which can be fatal without appropriate management Prompt diagnosis and management of these complications are imperative to prevent a desperate outcome. A 72-year-Old female with proximal left common iliac artery iatrogenic injury during lumbar discectomy was successfully treated by percutaneous deployment of a stent graft in an emergency setting. Postprocedural angiogram demonstrated complete exclusion of the iliac artery laceration. The patient became hemodynamically stable. Two weeks later she complained of vascular claudication. Follow-up angiography revealed decreased arterial flow in the opposite common iliac artery. An additional kissing stent was inserted into the right common iliac artery and the symptoms of vascular claudication disappeared. Endovascular stenting offers a safe and effective method for the treatment of an iatrogenic arterial laceration, particularly in a critical condition. But, the contralateral iliac arterial flow should be kept intact in case of proximal iliac artery injury. Otherwise, additional treatments may be needed.

Mesenteric injury occurs rarely in cases associated with blunt abdominal trauma. Despite its low incidence, mesenteric injury can lead to fatal outcomes such as hypovolemic shock due to hemoperitoneum or sepsis due to intestinal ischemia, or perforation-related peritonitis. For mesenteric injuries, especially those involving massive bleeding, intestinal ischemia, and perforation, the standard treatment is surgery. However, in the case of operative management, it should be borne in mind that there is a possibility of complications and mortality during and after surgery. The usefulness of transcatheter arterial embolization (TAE) is well known in solid organs but is controversial for mesenteric injury. We present a 75-year-old man with mesenteric injury due to blunt abdominal trauma. Initial abdominal computed tomography showed no hemoperitoneum, but a mesenteric contusion and pseudoaneurysm with a diameter of 17 mm were observed near the origin of the superior mesenteric artery. Since there were no findings requiring emergency surgery such as free air or intestinal ischemia, it was decided to perform nonoperative management with TAE using microcoils in hybrid emergency room system. TAE was performed successfully, and there were no complications such as bleeding, bowel ischemia, or delayed bowel perforation. He was discharged on the 23rd day after admission with percutaneous catheter drainage for drainage of mesenteric hematoma. The authors believe that treatment with TAE for highly selected elderly patients with mesenteric injuries has the positive aspect of minimally invasive management, considering the burden of general anesthesia and the various avoidable intraoperative and postoperative complications.

Purpose: Acute liver failure after massive partial hepatectomy is critical condition with high mortality. To prevent postoperative liver failure from being induced by a massive partial hepatectomy, many doctors do a minimal resection on the single lobe of the liver that might cause postoperative bleeding from the remaining ruptured parenchyma. The objective of this study was to assess clinical experience with postoperative hepatic arterial embolization to control bleeding from the remaining ruptured liver during the postoperative period. Methods: This retrospective 4-year study was conducted from May 2002 to April 2006 and included consecutive patients who had sustained massive hepatic injuries and who had undergone a laparotomy, followed by postoperative hepatic arterial angiographic embolization to control bleeding. Data on the injury characteristics, the operative treatment and embolization, and the amount of transfused packed red cells (PRBC) were gathered and analyzed. In addition, data on the overall complications and survival rate were collected and analyzed. Results: Every case showed severe liver injury, higher liver injury scaling grade IV. Only ten cases involved a ruptured bilateral liver lobe. A lobectomy was done in 6 cases, a left lobectomy was done in 3 cases, and a primary suture closure of the liver was done in 2 cases. Suture closure was also done on the remaining ruptured liver parenchyma in cases of lobectomies. The postoperative hepatic arterial embolizations were done by using the super-selection technique. There were some cases of arterio-venous malformations and anomalous vessel branches. The average amount of transfused PRBC during 24 hours after embolization was $2.36{\pm}1.75$, which statistically significantly lower than that before embolization. Among the 11 cases, 9 patients survived, and 2 died. There was no specific complications induced by the embolization. Conclusion: In cases of postoperative bleeding in severe hepatic injury, if there is still a large amount of bleeding, postoperative hepatic arterial embolization might be a good therapeutic option.

Purpose: A life-threatening hemorrhage resulting from a severe facial fracture is rare, but it needs a prompt and aggressive treatment. Especially, a massive oronasal bleeding combined with midfacial fracture which may result from the rupture of the internal maxillary artery. With the recent advances in the radiologic intervention, its use has increased for managing these life threatening case. We reviewed its usefulness with our experiences and literatures. Methods: A retrospective review was performed to determine the usefulness of the transcatheter arterial embolization in patients with panfacial trauma. If the vital signs were unstable, cardiopulmonary resuscitation was performed. Oronasal bleeding was controlled with nasal packing and electrocautery. All injured regions were studied by radiologic study including CT. Even after primary management, if the oronasal bleeding was persistent, radiologic intervention was performed 10 patients were treated with transcatheter arterial embolization and the bleeding focus controlled by embolization with polyvinyl alcohol and gelfoam. Results: After the intervention, the vital signs became stable and there were no complications from embolization in the follow-up for 6 months. Also patients could recover through appropriate operations. Conclusion: Transcatheter arterial embolization for maxillofacial injury has many advantages for both, the doctor and the patient. First, less pain is induced than a compression device or an operation, which is another way to treat oronasal bleeding. Second, it does not need general anesthesia. And through a single procedure not only we can know the accurate bleeding point, but we can also bleeding by embolization.

Transcatheter arterial embolization (TAE) for blunt hepatic injury in children is not common and is especially rare after damage control surgery (DCS). We report a successful TAE after DCS on a child for massive bleeding from the left hepatic artery due to a motor vehicle accident. The car (a sport utility vehicle) ran over the chest and abdomen of a 4-year-old boy. On arrival, initial vital signs were as follows: blood pressure, 70/40 mmHg; heart rate, 149/min; temperature, $36.7^{\circ}C$; respiratory rate, 38/min. After resuscitation, computed tomography was done, and a suspicious contrast leakage from a branch of the left hepatic artery and a spleen injury (grade V) were found. TAE was performed successfully after DCS for a liver injury.

To identify the pathogenetic role of reactive oxygen free radical-induced oxidation reaction in endotoxin-induced acute lung injury, we infused endotoxin into 8 domestic pigs; endotoxin only (n=3), pretreatment with dimethylthiourea (DMTU) (n=5). We observed the sequential changes in hemodynamic parameters, the concentration of plasma oxidized glutathione (GSSG) in pulmonary arterial and venous blood, and albumin content in bronchoalveolar lavage fluid (BALF). The results were as follows. 1) While cardiac output decreased, mean pulmonary arterial pressure, pulmonary vascular resistance, and alveolar-arterial oxygen difference increased over phase 1 (0-2 hr) and phase 2 (2-4.5 hr) by endotoxin, DMTU attenuated the above changes only during phase 2. 2) While the concentration of plasma GSSG increased significantly by endotoxin during phase 2, there were no significant differences between pulmonary arterial and venous GSSG contents during both phases. The increase in plasma GSSG content was attenuated by DMTU. 3) The content of BALF albumin was significantly lower in DMTU group than that of endotoxin group. These results suggest that reactive oxygen free radical-induced oxidation reaction may have an important pathogenetic role in endotoxin-induced acute lung injury in pigs, which seems to be greater during phase 2 rather than phase 1.
Background: Hyperinflation during lung ischemia has been known to improve pulmonary functions after reperfusion which may be exerted through a pulmonary vasodilation and avoidance of atelectasis by an increased surfactant release and been known whether the improvement of pulmonary function was the effect of hyperinflation itself or the oxygen content in inflation gas. Therefore we attempted to clarify the effect of hyperinflation with oxygen in pulmonary inflation gas during warm ischemia on pulmonary function after reperfusion to solve the problem of ischemia-reperfusion injury after lung transplantation. Material and Method: sixteen mongrel dogs were randomly divided into two groups: the left lung was inflated to 30-35 cm H2O with 100% oxygen in oxygen group and 100% nitrogen in nitrogen group. The inflated left lung was maintained with warm ischemia for 100 minutes. Arterial and mixed venous blood gas analysis and hemodynamics were measured before ischemia and 30, 60, 120, 180 and 240 minutes afer reperfusion. Lung biopsy was taken for the measurement of lung water content after the end of reperfusion. Result: In oxygen group arterial oxygen tension the difference of arterial and mixed venous oxygen tension and the difference of alveolar-arterial oxygen tension at 30-minute after reperfusion were not significantly different from those before ischemia and were stable during the 40hour reperfusion. However in nitrogen group these values were significantly deteriorated at 30-minute after reperfusion. there was no significant difference between two groups in hemodynamic data peak airway pressure and lung water content. Conclusion : The results indicated that the oxygenation one of the most important pulmonary functions was improved by pulmonary inflation with 100% oxygen during warm ischemia but the hemodynamics were not. Oxygen as a metabolic substrate during warm ischenia was believed to make the pulmonary tissues to maintain aerobic metabolism and to prevent ischemic damage of alveoli and pulmonary capillary.
The study was conducted in patients who had undergone angiography and arterial embolization after being diagnosed with arterial bleeding among those registered with severe trauma at the admission to the department of emergency due to accidents. In the study, comparison was done between the survived group and the nonsurvived group to investigate the usefulness and the optimal performance timing of angiography and embolization as the survival-affecting factors and treatment methods for patients. The study was performed as a retrospective analysis in 45 patients who had undergone angiography and arterial embolization among those categorized as severe trauma patients from the emergency department of H hospital located in Gyeonggi-do from July, 2006 until December, 2010. The Injury Severity Score (ISS), the Revised Trauma Score (RTS), the hematocrit were the main outcome measurements. Arterial embolization was technically successful in all cases, transcatheter arterial embolization of arterial bleeding is a useful procedure in lowering the mortality and complication in severe trauma patients. and RTS, ISS, Hematocrit were the predictable early mortality factors. So bad vital sign patients must be progressed rapidly.
