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.en-USSuperior vena cava syndromePulmonary venous collateralsComputed tomographySuperior Vena Cava Syndrome Associated with Right-to-Left Shunt through Systemic-to-Pulmonary Venous CollateralsJournal Article2014-04-1110.3348/kjr.2014.15.2.185
