Fig. 5 Photomicrographs of cross sections from left anterior descending artery of 74-year-old woman with acute anterior myocardial infarction who underwent intracoronary administration of streptokinase and immediate angioplasty. A, At level of angioplasty procedure, intimal tear (along left side of artery) led to adjacent intramedial dissection and focal adventitial hemorrhage. B, Extension of intramedial dissection tract led to formation of large hematoma (at top of artery) and subsequent severe extrinsic luminal compression (at bottom of artery), distal to site of balloon dilation.
