Transcatheter venography via both lumens using non-ionic contrast media (Ultravist, Schering, Berlin, Germany) showed retrograde reflux of contrast along the catheter shaft, which is characteristic of fibrin sheath formation (Figure 1).
a) Contrast reflux along side the catheter shaft characteristic of fibrin sheath; b) After stripping, contrast reflux (fibrin sheath) is no longer demonstrated.
