(a) Magnetic resonance tomography (MRT): breakup of the contrast medium in the superior vena cava (SVC) just before the right atrium. (b) Cavography depicted a subtotal stenosis of the SVC. Notably, the collateral contrast enhancement in the vena azygos. (c) Retrograde exposure of the SVC stenosis. (d) Successfully retrograde wire sounding of the SVC stenosis. (e) Effectively balloon-dilatation (maximum 10 mm diameter). (f) Postinterventional cavography revealed a stenosis-free flow/passage into the right atrium. Noteworthy, the clear decline of the collateral contrast enhancement in the vena azygos.

This MRT revealed a subtotal stenosis of the SVC just before the intersection into the right atrium (Figure 1(a)). Thereupon, a cavography was carried out and the VCS stenosis was dilated and reopened via balloon angioplasty (Figures 1(b)-1(f)).
