Figure 3
Transcatheter angiography through the triple-lumen catheter revealed extravasation of the contrast agent.
Arrow indicates extravasation of contrast agent detected outside of the SVC within the mediastinum.
Figure 4
Schema presenting of our hypothesis regarding the mechanisms underlying SVC perforation in this patient.
The catheter perforated the wall of the SVC. The drainage and return ports remained within the vessel; only the infusion port was detected outside the SVC.
CCV: Common carotid vein
SVC: Superior vena cava
PV: Pulmonary vein
