CTICasesAortic Dissection with Renal Artery Traversal
Imaging findings
CTA of the abdomen demonstrates a Stanford Type A dissection extending into the abdominal aorta. The left renal artery originates from the true lumen but physically traverses the false lumen without itself being dissected.
Key takeaways
In aortic dissections, visceral branches can have complex relationships with the true and false lumens, occasionally passing through a false lumen to reach their target segment, which can mimic localized sheath hematomas.
