In peripheral artery disease, younger patients have a lower mortality risk in the population, but have a higher risk ratio relative to the same-aged nationals. Furthermore, younger patients more likely have atherosclerotic risk factors. The prevalence of atherosclerotic risk factors is considerably different between peripheral artery disease and coronary artery disease. These features would be important to discuss practical strategies for the management of atherosclerotic risk factors in peripheral artery disease. Referral of patients with chronic limb-threatening ischemia to a vascular center would be another issue to be addressed in clinical practice.

A 76-year-old female was had dyspnea on effort and was diagnosed with pulmonary thromboembolism. She had pulmonary thromboembolism and deep vein thrombosis on computed tomography, and inferior vena cava (IVC) filter was placed. 10 days after IVC filter implantation, she suffered from low back pain. Computed tomography showed a retroperitoneal hematoma. Angiography was performed emergently and demonstrated a pseudoaneurysm at the fourth lumbar artery. Embolization of the lumbar artery was performed with coils. Lumbar artery pseudoaneurysm due to IVC filter implantation is a rare, but it is important to recognize the possibility of that complication.
