  • Title: Superior vena cava syndrome associated with right-to-left shunt through systemic-to-pulmonary venous collaterals.
    Author: Juan YH, Saboo SS, Anand V, Chatzizisis YS, Lin YC, Steigner ML.
    Journal: Korean J Radiol; 2014; 15(2):185-7. PubMed ID: 24644407.
    Abstract:
    Superior vena cava (SVC) obstruction is associated with the gradual development of venous collaterals. We present a rare form of systemic-to-pulmonary subpleural collateral pathway that developed in the bridging subpleural pulmonary veins in a 54-year-old woman with complete SVC obstruction. This uncommon collateral pathway represents a rare form of acquired right-to-left shunt due to previous pleural adhesions with an increased risk of stroke due to right-to-left venous shunting, which requires lifelong anticoagulation.
