medium · MCQ · Q-2783F1
A 65-year-old male with a history of long-standing systemic hypertension presents with sudden onset tearing chest pain radiating to the back. A contrast-enhanced CT angiogram of the aorta demonstrates an intimal flap extending from the ascending aorta distal to the subclavian artery down to the abdominal aorta. According to the Stanford classification, what type of aortic dissection is this?
- A.Stanford Type ACorrect answer
- B.Stanford Type B
- C.Stanford Type III
- D.DeBakey Type IIIb
Solution
The Stanford classification divides aortic dissections into Type A and Type B. Type A involves the ascending aorta (regardless of where the intimal tear originates or how far distally it extends), whereas Type B involves only the descending aorta (distal to the left subclavian artery). Since this dissection involves the ascending aorta, it is Stanford Type A.
