• Review of normal and variant venous anatomy in the thorax • The location of venous occlusion plays a role in development of collateral vessels • Arterial collaterals are less common, but can be appreciated on MR and CT

• Normal and variant venous anatomy of the thorax • Localization of collaterals depends on the level of occlusion. We will review the collateral pathways associated with the following scenarios: o Axillary or subclavian vein occlusion o Brachiocephalic vein occlusion o Superior vena cava occlusion   -Above azygos vein   -Below azygos vein   -Above and below azygos vein o Inferior vena cava occlusion   -Below the renal veins   -Between renal and hepatic veins   -Above hepatic veins • Normal and variant arterial anatomy of the thorax • Arterial collaterals of the thorax o Pulmonary artery o Bronchial artery o Aortic diseases
