A 50-year-old man who was known to have systemic hypertension developed sudden onset of severe back pain with associated diaphoresis. He lost consciousness approximately one hour after the onset of symptoms and, despite resuscitation attempts, died. An autopsy was conducted and he was found to have an acute aortic dissection originating just inferior to the left subclavian artery and extending to the iliac arteries (Stanford A/DeBakey IIIb). The following are microscopic sections of his left renal artery.
