Cardiovascular

Clinical Summary

A 50 Y/O man with hx of car accident

Imaging Procedures and Findings

This patient has right calavicular fracture and CT angiography of thorax is obtained . CT angiography demonstrates contrast collection in course of subclavian artery (middle part ) due to right subclavian rupture and pseudoaneurysm formation. .

Discussion

Contrast-enhanced CT scan be used to evaluate both indirect (mediastinal hemorrhage) and direct signs of vesseles injuries. Mediastinal hemorrhage appears as either diffuse or focal soft tissue attenuation surrounding mediastinal structures, and the location of the blood has diagnostic significance. Hemorrhage in the vicinity of and surrounding the aorta and other vascular structures is more suggestive of vascular injury.Direct signs of vessel injury are polypoid (clot) or linear (intimal flap) intraluminal areas of low attenuation, pseudoaneurysm, irregularity of the aortic wall, pseudocoarctation, intramural hematoma, dissection, and frank extravasation of contrast material.

Final Diagnosis

Psuedoaneurysm of right subclavian artery
