[Anaphylactic reaction with coronary spasm following coronarography].

The authors report a case of anaphylactic shock following the injection of iodinated contrast medium for coronary angiography and complicated by two spasms affecting segments II and III of the right coronary. Vasospasm was relieved by the injection of linsidomine, revealing an angiographically healthy segment III. Such complications associated with various substances, notably iodinated contrast media, are rare.
