Background Endovascular treatment is used for traumatic arterial injuries in the torso. However, the effectiveness of endovascular covered stent‐graft treatment for peripheral artery injury is unclear. We present a case of superficial femoral artery (SFA) injury successfully treated with a covered stent‐graft. Case Report A 68‐year‐old man presented with traumatic lower limb injury and shock. Computed tomography angiography revealed left subtrochanteric fracture and hematoma with extravasation. Digital subtraction angiography revealed extravasation from a left SFA branch, and a pseudoaneurysm at the SFA trunk. We coil embolized the SFA branch, and treated the pseudoaneurysm with a covered stent‐graft. Computed tomography carried out 22 days later showed complete pseudoaneurysm exclusion and sufficient stent patency. Conclusion We successfully used a covered stent‐graft to treat SFA injury due to blunt trauma. A covered stent‐graft could be effective for peripheral artery injury., A 68‐year‐old man presented with lower limb injury and shock after a fall, and digital subtraction angiography revealed extravasation from a proximal branch of the left superficial femoral artery and a pseudoaneurysm at the superficial femoral artery trunk. We used a coil to embolize the superficial femoral arterial branch, and a covered stent graft to treat the pseudoaneurysm. A covered stent graft could be effective for peripheral artery injury; however, the long‐term complications are unclear.

Twenty‐nine cases (55.7%) showed traumatic intracranial hemorrhagic injury progression during interventional radiology. Age (P = 0.029), Glasgow Coma Scale at admission (P = 0.001), Revised Trauma Score (P = 0.036), Trauma and Injury Severity Score probability of survival (P = 0.043), platelet count (P = 0.005), D‐dimer level (P = 0.046), fibrinogen level (P = 0.016), and hemoglobin level (P = 0.003) differed significantly between the enlarged and non‐enlarged groups., Aim To identify factors affecting the progression of traumatic intracranial hemorrhagic injury (t‐ICH) during interventional radiology (IVR) for the hemostasis of extracranial hemorrhagic injury. Methods This was a retrospective comparative study. Fifty‐two patients with t‐ICH who underwent hemostasis using IVR for extracranial trauma at our institute were included. Clinical and computed tomography scan data were collected to investigate factors associated with t‐ICH progression. Results Fifty‐two subjects (36 men/16 women) with a mean age of 70.9 ± 19.2 years were analyzed. The mean Injury Severity Score was 34.9 ± 11.2. In 29 patients (55.7%), t‐ICH progressed during IVR. Hematoma progression frequently occurred in patients with acute subdural hematoma (56.2%) and traumatic intracerebral hematoma/hemorrhagic brain contusion (66.6%). Factors associated with t‐ICH progression included age (P = 0.029), consciousness level at admission (P = 0.001), Revised Trauma Scale (P = 0.036), probability of survival (P = 0.043), platelet count (P = 0.005), fibrinogen level (P = 0.016), hemoglobin level (P = 0.003), D‐dimer level (P = 0.046), and red blood cell transfusion volume (P = 0.023). Conclusion Aggressive correction of anemia, thrombocytopenia, and low fibrinogen levels in severe consciousness disturbance patients with acute subdural hematoma and traumatic intracerebral hematoma/hemorrhagic brain contusion could improve the prognosis after IVR for hemostasis of extracranial hemorrhagic injuries.
