BACKGROUND
Aortic intramural hematoma (IMH) associated with aortic branch tear and intramurally located pseudoaneurysm after blunt trauma has not been reported. Here, we report a case of progressive type A aortic IMH associated with a pseudoaneurysm arising from the injured proximal renal artery after blunt trauma.
CASE SUMMARY
During logging operations, a 66-year-old man experienced blunt force trauma after being injured by a fallen tree. He arrived at our trauma center with a left flank pain complaint. Computed tomography (CT) revealed a pseudoaneurysm arising from the proximal renal artery (localized within the aortic media) and Stanford type A IMH. A covered stent was deployed along the left main renal artery, bridging the pseudoaneurysm and covering the parent artery, successfully excluding the pseudoaneurysm as confirmed using aortography. However, although the degree of the pseudoaneurysm decreased, follow-up CT revealed remnant pseudoaneurysm, likely caused by an endoleak. Subsequently, a covered stent was additionally installed through the previously deployed covered stent. Successful exclusion of the pseudoaneurysm was confirmed using final aortography. In the 7-mo follow-up CT scan, the IMH and pseudoaneurysm completely disappeared with no evidence of stent-related complications.
CONCLUSION
Endovascular treatment such as stent-graft placement can be an effective and safe treatment for traumatic renal artery injury.
Core Tip: We report the case of an adult male who presented with left flank pain after experiencing blunt trauma from being injured by a fallen tree. Investigations revealed a pseudoaneurysm arising from the proximal renal artery and Stanford type A IMH. The patient received endovascular treatment, and the successful exclusion of the pseudoaneurysm was confirmed using final aortography. A postoperative computed tomography scan showed the complete disappearance of the intramural hematoma and pseudoaneurysm with no stent-related complications. Consequently, we propose that endovascular treatment such as stent-graft placement can be an effective and safe treatment for traumatic renal artery injury.
