Common venous malpositioning. a The venous catheter, implanted via the subclavian vein, enters the contralateral brachiocephalic vein (arrow). b Loop formation in the subclavian vein. c–e Malpositioning in the mammarian vein due to occlusion of the SVC. c PA chest film shows normal course of the catheter, which had been implanted into the internal jugular vein. d However, the lateral projection shows an abnormal anterior course. e Sagittal MIP CT reconstruction confirms malpositioning into the internal mammary vein
