Peripheral blood eosinophilia associated with gastrointestinal administration of iodinated contrast media.

Objective: This study was designed to assess whether gastrointestinal administration of iodinated contrast media results in peripheral blood eosinophilia.

Materials And Methods: We studied 110 patients in a retrospective review. Diatrizoate meglumine and diatrizoate sodium for abdominal CT were administered to 98 of these patients; 22 of the 98 had also been given the same contrast medium administered by enema.

Stenotic origin of an aberrant left subclavian artery from a right-sided aortic arch. A case report.

A patient with a right-sided aortic arch giving origin to an aberrant left subclavian artery with circumferential ostial stenosis is reported. This asymptomatic anomaly was discovered serendipitously during cerebral arteriography for subarachnoid hemorrhage. The embryologic origin of this anatomic variant is discussed, as are some practical implications relating to the angiographic technique of selective catheterization of branches of the aortic arch.
