Use of IABP in contrast media-induced anaphylactic shock: the ultimate lifesaver.

Anaphylactic reaction to contrast media during selective coronary angiography is a rare occurrence. It can be occasionally resistant to medical treatment leading to cardiovascular collapse and death. The use of intra-aortic balloon pump (IABP) counter-pulsation when the supportive medical treatment fails during anaphylactic shock is not well documented in the literature. We report a case of a severe contrast media-induced anaphylactic shock which failed to respond to the supportive medical management and the timely insertion of IABP for further circulatory support that prevented death in a patient who had an elective diagnostic coronary angiography. The clinical diagnosis of anaphylaxis was challenging at the onset of shock as the typical rash developed after a few minutes.
