Congenital left brachiocephalic vein and superior vena cava aneurysms in an infant: final update with autopsy findings

摘要

We previously have described the case of an infant with congenital left brachiocephalic vein and superior vena cava (SVC) aneurysms in The Journal. Unfortunately, the patient died of chronic respiratory failure at 22 months of age because a tracheostomy could not be performed, and an autopsy was performed Mosby, Inc.Results of a gross inspection revealed numerous collateral veins of various sizes, which branched from the aneurysms and connected to the esophageal varices. The dilated blood vessel that we initially described as an SVC aneurysm was actually found to be a right brachiocephalic vein undergoing fusiform dilatation, and the SVC was not dilated. The left brachiocephalic vein aneurysm was saccular and composed of numerous interconnected cystic lesions containing thrombi (Figure 1).
