Central venous catheterization is a common diagnostic and therapeutic procedure in modern clinical practice. Pseudoaneurysms of the subclavian artery are rare and usually occur immediately after the causative event, whether the cause was trauma or a medical procedure. Here we report the rare case of a 71-year-old woman with delayed presentation of catheter-related subclavian pseudoaneurysm. The patient was treated for aspiration pneumonia with respiratory failure in another hospital. The patient's chest wall swelling began two weeks after the initial catheterization in the other hospital, probably because of slow leakage of blood from the injured subclavian artery caused by incomplete compression of the puncture site and uremic coagulopathy. She was successfully treated with ultrasound-guided thrombin and angiography-guided histoacryl injection without stent insertion or surgery. Her condition improved, and she was discharged to her home.
