Abstract
BACKGROUND

Infectious common femoral artery pseudoaneurysm caused by Klebsiella 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 Klebsiella pneumoniae 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 Klebsiella pneumoniae deriving from the pulmonary infection. Moreover, this unusual case highlights the use of EVT and prolonged antibiotic therapy for infectious pseudoaneurysm.

Core Tip: Infectious pseudoaneurysm of the femoral artery is a rare entity that is potentially life and limb threatening. Common femoral artery (CFA) pseudoaneurysm caused by Klebsiella pneumoniae has not been reported. We reported a rare infectious CFA pseudoaneurysm, which was caused by previous pulmonary infection of Klebsiella pneumoniae. After endovascular treatment (EVT) and long-term antibiotic therapy, the patient had a good result at the 1-year follow-up. This case demonstrates common femoral artery pseudoaneurysm can be caused by Klebsiella pneumoniae deriving from the pulmonary infection. Moreover, it highlights the use of EVT and prolonged antibiotic therapy for infectious pseudoaneurysm.
