History: 65 year old male status post coronary artery bypass graft surgery.

The upward pointing arrow on the patient’s right labels a Swan-Ganz catheter coursing through the right internal jugular vein and ending in the right pulmonary artery. The downward pointing arrow on the patient’s left labels a mediastinal drain. The leftward pointing arrow over the patient’s trachea indicates the tip of the endotracheal tube. The rightward pointing arrow over the patient’s upper abdomen indicates the side-hole of an nasogastric tube. A portion of the nasogastric tube external to the patient and multiple telemetry wires also overlie the chest. While the mediastinal silhouette appears widened, this is a normal expected finding after CABG. Additionally, the perihilar ground glass and reticular opacities indicative of mild interstitial pulmonary edema is commonly seen after CABG.
