Successful endovascular treatment with long-term antibiotic therapy for infectious pseudoaneurysm due to : A case report.

Background: Infectious common femoral artery pseudoaneurysm caused by pulmonary infection is a relatively infrequent entity but is potentially life and limb threatening. The management of infectious pseudoaneurysm remains controversial.

Case Summary: We reported a 79-year-old man with previous pulmonary infection and multiple comorbidities who presented with a progressive pulsate mass at the right groin and with right lower limb pain. Computed tomography angiography showed a 6 cm × 6 cm × 9 cm pseudoaneurysm of the right common femoral artery accompanied by occlusion of the right superficial femoral artery and deep femoral artery. He underwent endovascular treatment (EVT) with stent-graft, and etiology of infectious pseudoaneurysm was confirmed. Then, 3-mo antibiotic therapy was given. One-year follow-up showed the stent-graft was patent and complete removal of surrounding hematoma.

Conclusion: The femoral artery pseudoaneurysm can be caused by deriving from the pulmonary infection. Moreover, this unusual case highlights the use of EVT and prolonged antibiotic therapy for infectious pseudoaneurysm.
