[Occlusive spasm of a coronary artery not treated during angioplasty. Apropos of a case].
The authors report the case of a patient who, during percutaneous transluminal angioplasty of the circumflex artery, developed sudden occlusion of the anterior interventricular artery without stenosis and not touched by the operator. The fact that this occlusion was completely reversible after an intra-coronary injection of nitroglycerin suggests that this was due to spasm. This case suggests the possibility of consequences of angioplasty at a point distant from the dilated site. The authors use this case and a review of the literature to discuss the pathophysiological mechanisms which could be responsible for such consequences.
