RESUMO
Central venous catheters provide long-term available vascular access. They are useful for central venous pressure monitoring, rapid fluid management, massive transfusion and direct cardiovascular medication, especially in operation. Central venous catheterization is usually performed by the landmark bedside technique without imaging guidance. The complications of central venous catheterization are frequent, which include malposition, pneumothorax, hemothorax, chylothorax, arterial puncture, hematoma, air embolism and infection. Malposition of a central venous catheter is not rare and may cause several complications such as malfunction of the catheter, default measurement of central venous pressure, catheter erosion, thrombophlebitis and cardiac tamponade. In this case, we report a malposition of central venous catheter with 9-Fr introducer sheath which is located in the right subclavian vein via ipsilateral internal jugular vein and the correction of this misplacement assisted by mobile type diagnostic X-ray apparatus (C-arm fluoroscope).
