Obtaining central venous access is a standard procedure necessary for safe anesthesia in patients undergoing surgery with extracorporeal circulation. It is well known that jugular way is safer and causes less complication than subclavian. The authors present a case of accidental left subclavian artery cannulation during left internal jugular vein catheterisation. Due to the complex character of myocardial revascularization procedure with extracorporeal circulation and specific catheter localization surgical removal was necessary. This case underline well documented high risk of internal jugular vein cannulation even in operating room condition.
