Post-arteriography cholesterol embolism

Cholesterol crystal embolism (atheroembolism)

Cholesterol crystal embolism, known as atheroembolic disease, is caused by showers of cholesterol crystals from an atherosclerotic plaque that occludes small arteries. Embolization can occur spontaneously or as an iatrogenic complication from an invasive vascular procedure (angiography or vascular surgery) and after anticoagulant therapy. The atheroembolism can give rise to different degrees of...

Post-mortem arteriography of cerebral arteriovenous malformations.

Post-mortem arteriography has been used to show interarterial anastomoses in the leptomeninges (Vander Eecken and Adams, 1953) and pathological cerebral arterial patterns in infarcts (Hutchinson and Yates, 1957; Stein, McCormick, Rodriguez, and Taveras, 1962; Rodda and Dugdale, 1963), in hypertension (Russell, 1963), and in cerebral haemorrhage (Johnson and Yates, 1956; Cole and Yates, 1967), b...

How common is cholesterol embolism?

Histological sections of spleen and both kidneys from 372 necropsies were examined for the presence of cholesterol emboli. These were identified in nine (2.4%) cases and the clinical histories of these cases were reviewed. All the subjects with cholesterol emboli were older than 60 years and eight out of nine were male. Lesions of differing ages were found in individual cases, suggesting that t...

Post-mortem Coronary Arteriography and Its Correlation with Electrocardiography.

Myocardial anoxia may arise in one of three ways. There may be narrowing and obstruction of the coronary arteries, or the oxygen-carrying power of the blood may be reduced, or there may be relative impairment because of the increased demands of a great bulk of muscle. Under such circumstances, a collateral circulation develops; and Schlesinger (1938), Blumgart, Schlesinger, and Davis (1940), an...
