[...]. Proximal Interruption of the Right Pulmonary Artery with Coronary Collaterals. CTICases. Published December 18, 2015. https://str-case-explorer.pages.dev/c/exzd9
Imaging findings
Chest radiograph showed findings consistent with proximal interruption of the right pulmonary artery, including a slightly small right lung and relative vessel caliber differences. CT and coronary angiogram demonstrated extensive systemic arterial supply to the affected lung from various sources, notably large collateral vessels originating from both the left and right coronary arteries.
Key takeaways
Proximal interruption of a pulmonary artery leads to systemic collateral supply to the affected lung, which can arise from numerous sources including intercostal, internal mammary, mediastinal, diaphragmatic, and even coronary arteries. This rare presentation of prominent coronary collaterals can raise the possibility of coronary steal phenomenon.
