Abstract

Vasospasm related to ergot intoxication has been recognised since the Middle Ages when it occurred due to ingestion of rye contaminated with Claviceps purpurea. Today ergotism is a rare cause of peripheral ischaemia, most often associated with ergotamine tartrate therapy for migraine headaches. Recognition of the typical angiographic pattern is important, as the classic drug history may not be obtained, and the cause of the ischaemia can be overlooked. Early diagnosis is important as the outcome may be serious if left untreated. Arterial vasospasm, collateralisation, and secondary thrombus formation are the major angiographic findings. Ergotism responds to conservative therapy which includes drug withdrawal, intravenous nitroprusside, fluid therapy and heparinisation. We describe the angiographic findings of four cases and report on the results of therapy.

Blood Clotting Disorders

Thrombophilia includes conditions with increased tendency for excessive blood clotting. Blood clotting occurs when the body has insufficient amounts of specialized proteins that make blood clot and stop bleeding. Here is the latest research on blood clotting disorders.
