Central venous catheterization allows the measurement of hemodynamic variables, the delivery of medications, and nutritional support. The placement of central venous catheterization is associated with adverse events, such as, arterial puncture, hematoma, A-V fistula, pseudoaneurysm, etc. We report a case of a superficial femoral artery pseudoaneurysm after removing a femoral vein catheter in a 48-year-old female patient undergoing cervical spinal fusion. An insidious arterial puncture not noticed during femoral vein catheterization may produce complications immediately after catheter removal. Whenever a central venous catheter is removed, the importance of firm and even compression for a sufficient length of time cannot be overemphasized.
