  • Title: [A case of obstruction in the left internal jugular vein which both ultrasound prescan and chest computed tomography could not detect before the insertion of a pulmonary artery catheter].

    Abstract:
    In a 54-year-old man, at the time of anesthesia administration during the Bentall re-operation, a preoperative ultrasound scan showed right internal jugular vein thrombosis before insertion of a pulmonary artery catheter into the right internal jugular vein. Therefore, we performed the insertion after confirming that the left internal jugular vein was safe via a preoperative ultrasound and chest computed tomography (CT). Although we could insert the catheter sheath, contrast imaging revealed that the pulmonary artery catheter had advanced no further than approximately 15 cm into the left internal jugular vein. Similar advancement was noted when inserting the pulmonary artery catheter under fluroscopic guidance. This indicated an obstruction in the confluence of the left internal jugular vein and the brachiocephalic vein. A postoperative chest contrast CT showed thrombosis in the confluence of the left internal jugular vein and the brachiocephalic vein. Considering that the chest CT scan was performed 2 months before the surgery, it is necessary to perform imaging again before surgery.
