A 71 year old man had transfemoral catheterization for coronary angiography which revealed the presence of severe atherosclerotic narrowing of all major coronary arteries. Within hours of the procedure, he developed severe left lower quadrant abdominal pain. which was later associated with rebound tenderness, livido reticularis (erythematous skin rash) of the abdominal skin, increasing hypertension, cold blue toes and
progressively worsening renal failure. Laparotomy revealed necrosis of the descending colon. This was resected. Microscopic examination showed amorphous eosinophilic material containing slit-like spaces occluding arteries in the submucosa. Which one of the following is the most likely explanation?
a. thromboemboli secondary to myocardial infarction.
b. type B dissection of the aorta.
c. hypersensitivity vasculitis.
d. atheroembolism.
