Summary We compared four different skin surface landmarks, the lower margin of the right 2nd costo‐sternal junction (point A); the upper margin of the right 3rd costo‐sternal junction (point B); the lower margin of the right 3rd costo‐sternal junction (point C); and a point 5 cm below the manubrio‐sternal junction (point D), in 20 cancer patients undergoing insertion of permanent central venous catheters whose tips were placed near the superior vena cava – right atrium (SVC‐RA) junction under transoesophageal echocardiography guidance. The landmark was satisfactory if it was located within 1 cm of the SVC‐RA junction. Points C and D were closer to the SVC‐RA junction than points A and B (p < 0.0001). However, point C had the highest incidence (C: 70%, A: 0%, B: 20%, D: 30%, p < 0.0001) of being within 1 cm of the SVC‐RA junction.
