Click 49 year old man with duplicate SVC, interrupted IVC and lower extremity DVT. FINDINGS: This series shows the formation of the left brachiocephalic vein, which remains separate from the right brachiocephalic vein at the level of the aortic arch. The left brachiocephalic vein continues as a separate left superior vena cava inferiorly alongside the left side of the heart. The drainage path of the left superior vena cava cannot be confirmed, as this scan did not use IV contrast. Analyzing the anatomy of the great vessels was not the intent of performing this scan. TECHNIQUE: Computer tomography of the chest was performed without intravenous or oral contrast using Philips Briliance 64 CT machine (Cleveland, OH) with slice thickness 5mm 120 kVp, 106- 228 mAs

Click 49 year old man with duplicate SVC, interrupted IVC and lower extremity DVT. FINDINGS: This coronal CT scan reconstruction shows the presence of a persistent left superior vena cava. TECHNIQUE: Computer tomography of the chest was performed without intravenous or oral contrast using Philips Briliance 64 CT machine (Cleveland, OH) with slice thickness 5mm 120 kVp, 106- 228 mAs.

Click 49 year old man with duplicate SVC, interrupted IVC and lower extremity DVT. FINDINGS: Venogram performed during IVC filter placement showing interrupted IVC. Injection of the contrast showed a 3 cm segment of interruption in the inferior vena cava with numerous large collaterals formed in lieu of a continuous IVC. TECHNIQUE: Omnipaque 140 - 50 ml was used for venogram.
