A unique constellation of multiple aortic and caval anomalies-Truncus bicaroticus with right aberrant subclavian artery, and persistent left sided SVC with left sided azygous vein-imaging and clinical implications

Abstract

Case Report: Barium swallow study showed posterior indentation on esophagus. On MDCT, an abnormal couse of RSA was seen behind the esophagus. Bilateral carotids were seen to be arising from a common midline trunk- often called truncus bicaroticus double SVC was seen with persistent left SVC draining into the coronary sinus. A prominent retroaortic azygous vein was seen draining into the left SVc with absence of right azygous.
