[Bronchospasm, apnea and heart arrest following dipyridamole perfusion scintigraphy].

The occurrence of fatal respiratory insufficiency following dipyridamole-thallium imaging is described. The patient, a 67-year-old man, had a history of chronic obstructive lung disease. Since patients with a history of chronic obstructive lung disease have an increased risk of developing bronchospasm after dipyridamole infusion, it is advised to be cautious in performing dipyridamole-thallium imaging in these patients. Dobutamine may be an acceptable alternative to dipyridamole in these patients.

Cholesterol embolism as a complication of left heart catheterisation. Report of seven cases.

Cholesterol embolism after left heart catheterisation by the femoral approach was diagnosed in seven men (mean age 59.6 years) out of a total of 4587 catheterisations. Diabetes was present in four patients, systemic hypertension in three, and signs of extensive atherosclerosis in six; five patients were taking anticoagulant drugs. Acute pain in the legs or abdomen occurred in six patients, two of whom had abdominal angina; renal failure was present in six patients, cutaneous manifestations in five, and a cholesterol embolus was seen in the retina in one. Six out of six patients had an appreciable increase in the erythrocyte sedimentation rate and five out of five had eosinophilia within a week of catheterisation. Renal failure was progressive in five patients, one of whom required haemodialysis. Three patients required amputation of the toes because of gangrene. Four patients died within four and a half months of catheterisation from causes not directly related to cholesterol embolism. At necropsy cholesterol emboli were found in all four patients. Cholesterol embolism is a rare but serious complication of left heart catheterisation.
