Catheter Angiography May Be An Unnecessary Follow-up To CT Angiography

Science Daily — Even in challenging cases, CT angiography (CTA) offers an accurate and rapid diagnosis for blunt trauma victims who may have aortic or great vessel injury negating the need for more invasive procedures, according to a recent study conducted by radiologists at the University of Washington and the Harborview Injury Prevention and Research Center in Seattle, WA.

CTA is commonly used to rule out blunt aortic and intrathoracic great vessel injuries, but sometimes the results are indeterminate, said Marla Sammer, MD, lead author of the study. When the results are indeterminate, a subsequent catheter angiography is usually performed.
