Fig 4 Portable CXR in a critically ill patient shows two CVCs in situ, both inserted from the left internal jugular vein. One is a standard multilumen catheter and the other is a dialysis catheter. The tip of the former is poorly positioned at the junction of the innominate vein and SVC. The stiffer larger bore dialysis catheter is in an even worse position, abutting and tenting the wall of the SVC at an acute angle with significant risk of pain, thrombosis, infection, perforation, and malfunction.

Fig 5 Stylized anatomical figure dividing the great veins and upper RA into three zones (A–C), representing different areas of significance for placement of CVCs. See text for further description. Zone A, upper RA and lower SVC; Zone B, upper SVC and junction of left and right innominate veins; Zone C, left innominate vein.
