title: Cholesterol crystal embolization and the digestive system.
abstract: Atherosclerotic vascular disease can give rise to provoked or spontaneous cholesterol crystal embolization to organ systems. Lodging in downstream arterioles, these crystals can produce granuloma formation, infarction, ulceration, and perforation. Histologic sections of the tissue concerned invariably show pathognomonic empty needle-shaped clefts left by the crystals after processing of the material. In the digestive system these events can cascade to many and often misleading presentations. They can be the cause of massive bleeding, acute acalculous cholecystitis, pancreatitis, or teleangiectasis with chronic intractable blood loss. Owing to the progressive nature of the disease the treatment options described in this paper can only give temporary, but nevertheless often worthwhile relief.
