RationaleVascular involvement manifests as aneurysms, stenosis, and arteriovenous malformations in patients with type I neurofibromatosis (NF-I). Aneurysms are rare; however, the renal artery is the most common site. Herein, we report a rare case of stent graft placement in an anterior tibial artery (ATA) pseudoaneurysm in a patient with NF-I.Patient ConcernsA 52-year-old woman with NF-1 was admitted to the emergency room with painful swelling in the left lower leg. At presentation, the patient's blood pressure was 100/60 mmHg and the hemoglobin level was 9 g/dL.DiagnosesComputed tomography scan revealed a small aneurysm arising from the left ATA and an adjacent large hematoma.InterventionStent graft placement was performed to treat ATA pseudoaneurysm.OutcomesAfter stent graft placement, the aneurysm disappeared and the distal flow was patent through the ATA.LessonsStent graft placement should be considered as another option for endovascular treatment in patients in whom coil embolization or surgery cannot be performed.Copyright © 2022 the Author(s).
