Spontaneous cholesterol embolization. A rarely reported entity.

Cholesterol embolization sometimes occurs after invasive procedures involving manipulation of the aorta or its major branches, and less commonly occurs after thrombolytic therapy for acute myocardial infarction. Rarer still is spontaneous cholesterol embolization, a case of which we now report. Our patient experienced peripheral embolization, the origin of which was traced to the infrarenal aortic segment and the common iliac vessels. Aortoiliac reconstruction was successful; we believe that surgical management of this condition should be performed in selected cases.

Spontaneous cholesterol embolization--a rare clinical entity.

Embolization of cholesterol crystals from atheromatous plaques is a rare entity most often seen after invasive procedures involving manipulation of the aorta. Spontaneous CE has been reported in very rare cases. Peripheral signs include livedo reticularis, muscle pain and palpable pulses. Depending on the site of the responsible plaque, emboli may involve visceral organs and produce a systemic illness. Diagnosis is confirmed using skin, muscle and/or renal biopsies. Surgery is recommended when the atheromatous disease is localized to a unique segment which can be replaced.

Traumatic rupture of the thoracic aorta--case report.

Acute traumatic rupture of the thoracic aorta due to blunt trauma is a relatively common injury after deceleration accidents. However, only one fifth of these patients survive to reach medical facilities. The limiting factor to successful management is early diagnosis and prompt treatment. A case of acute traumatic rupture of the descending aorta due to blunt trauma is presented. Diagnostic and management modalities are discussed.
