Renal injuries occur in more than 10% of patients who sustain blunt abdominal injuries. Non-operative management (NOM) is the established treatment strategy for lowgrade (I–III) renal injuries. However, despite some evidence that NOM can be successfully applied to high-grade (IV, V) renal injuries, it remains unclear whether NOM is appropriate in such cases. The authors report two cases of high-grade renal injuries that underwent NOM after embolization in a hybrid emergency room (ER) system with a 24/7 in-house interventional radiology (IR) team. A 29-year-old male visited Wonkwang University Hospital Regional Trauma Center complaining of right abdominal pain after being hit by a rope. Computed tomography (CT) was performed 16 minutes after arrival, and the CT scan indicated a grade V right renal injury. Arterial embolization was initiated within 31 minutes of presentation. A 56-year-old male was transferred to Wonkwang University Hospital Regional Trauma Center with a complaint of right flank pain. He had initially presented to a nearby hospital after falling from a 3-m height. Thanks to the key CT images sent from the previous hospital prior to the patient’s arrival, angiography was performed within 8 minutes of the patient’s arrival and arterial embolization was completed within 25 minutes. Both patients were treated successfully through NOM with angioembolization and preserved kidneys. Hematoma in the first patient and urinoma in the second patient resolved with percutaneous catheter drainage. The authors believe that the hybrid ER system with an in-house IR team could contribute to NOM and kidney preservation even in high-grade renal injuries.

Super-selective renal artery embolization is an increasingly popular technique for the management of traumatic, low-grade renal trauma. When performed in distal arterial branches, this intervention enables tissue preservation and arrest of hemorrhage, but it may not be practical in cases of multifocal, high-grade renal injuries. In such cases, surgical nephrectomy remains the more common treatment modality to ensure hemodynamic control. We present the unique case of a patient who presented in hemorrhagic shock following a major trauma that resulted in a grade 5 renal injury treated with complete renal artery embolization using Gelfoam, resulting in hemodynamic stabilization. Interestingly, imaging 1 month after embolization revealed residual enhancement of the inferior pole of the kidney, suggesting reconstitution of flow and partial renal salvage. Ultimately, transcatheter “nephrectomy” with careful selection of a temporary embolic agent may serve as a safe and efficient alternative to surgical nephrectomy with the added possibility of preserving partial renal perfusion and function in the emergent setting.

Gallbladder injuries are rare in cases of blunt abdominal trauma and are usually associated with damage to other internal organs. If the physician does not suspect gallbladder injury and check imaging studies carefully, it may be difficult to distinguish a gallbladder injury from gallbladder stone, hematoma, or bleeding. Therefore, in order not to miss the diagnosis, the clinical findings and correlation should be confirmed. In the present case, a 60-year-old male presented to a local trauma center complaining of pain in the upper right quadrant and chest wall following a motor vehicle collision. Abdominal computed tomography (CT) showed a hepatic laceration and hematoma in the parenchyma in segments 4, 5, and 6 and active bleeding in the lumen of the gallbladder. Traumatic gallbladder injuries generally require surgery, but in this case, non-operative management was possible with cautious follow-up consisting of abdominal CT and angiography with repeated physical examinations and hemodynamic monitoring in the intensive care unit.
Splenic injury is a common result of blunt trauma, and bleeding occurs mainly inside the splenic capsule and may leak into the peritoneal space. Herein, we report a case where active bleeding occurred in the splenic artery and only leaked into the extraperitoneal space. This is the first case of this phenomenon in a trauma patient in the English-language literature. Bleeding passed through the peritoneum, leaked into the anterior pararenal space, and continued along the extraperitoneal space to the prevesical space of the pelvis. Therefore, on the initial computed tomography (CT) scan, the bleeding appeared to be in the left paracolic gutter, so we suspected mesenteric bleeding. However, after the CT series was fully reconstructed, we accurately read the scans and confirmed splenic injury with active bleeding. If there had been a suspicion of bowel or mesenteric injury, surgery would have been required, but fortunately surgery could be avoided in this case. The patient was successfully treated with angioembolization.
A Morel-Lavallée lesion is a closed degloving injury caused by traumatic separation of the skin and subcutaneous tissue from the underlying fascia. However, since physicians tend to focus on treating the bone fracture, hemodynamic instability accompanying a Morel-Lavallée lesion can sometimes be overlooked. We report the case of a hemodynamically unstable 73-year-old man who had a Morel-Lavallée lesion of the thigh, but no femur fracture. Angiography showed active bleeding from the muscular branch of the right deep femoral artery, which was then successfully embolized.
The purpose of this study was to determine the essential factors for prompt arrangement of angio-embolization in patients with pelvic ring fractures.
A total of 62 patients with pelvic ring fractures who underwent angio-embolization in Dankook University Hospital from March 2013 to June 2018 were retrospectively reviewed. There were 38 men and 24 women with a mean age of 59.8 years. The types of pelvic ring fractures were categorized according to the Tile classification. Patient variables included sex, initial hemoglobin concentration, initial systolic blood pressure, transfused packed red blood cells within 24 hours, Injury Severity Score (ISS), mortality rate, length of hospital stay, and time to angio-embolization.
The most common pelvic fracture pattern was Tile type B (n=34, 54.8%). The mean ISS was 27.3±10.9 with 50% having an ISS ≥25. The mean time to angio-embolization from arrival was 173.6±89 minutes. Type B (180.1±72.3 minutes) and type C fractures (174.7±91.3 minutes) required more time to angio-embolization than type A fractures (156.6±123 minutes). True arterial bleeding was identified in types A (35.7%), B (64.7%), and C (71.4%).
It is important to save time to reach the angio-embolization room in treating patients with pelvic bone fractures. Trauma surgeons need to consider prompt arrangement of angio-embolization when encountering Tile type B or C pelvic fractures due to the high risk of true arterial bleeding.
