Figure 16b. Transsternal approach. (a) Contrast-enhanced CT scan shows a retrotracheal mass (M) posterior to the right and left brachiocephalic veins (V). (b) CT scan shows a 22-gauge biopsy needle (arrowhead) coaxially introduced through an 18-gauge transsternal needle (arrow). The biopsy needle transgresses the left brachiocephalic vein (V) to obtain a sample of the mass (M).
