[Recanalization of chronic occlusions and myocardial infarction occurring during reocclusion. Apropos of 2 cases].

Although recent techniques have significantly improved the frequency of disobliteration of chronic occlusions, the potential complications in terms of mortality, emergency bypass surgery and myocardial infarction seem as common as in angioplasty of stenosis. Of these complications, the occurrence of infarction during reocclusion at the site of angioplasty has not been described and even been refuted by some authors. We report two cases of acute infarction, one of which was transmural, occurring during late reocclusion after disobliteration of a chronically occluded artery.
