Fig. 5From: Discussion on the causes of thrombolysis failure in a patient with STEMI: a case reportThe IVUS catheter was withdrawn from the distal end of the LAD (due to the slender distal end, IVUS failed to evaluate the near apical segment of the LAD), and the results showed that the spontaneous dissection in the distal LAD segment had healed well and that the haematoma had been resorbed. Residual haematoma may have remained in the distal area near the apical segment of the LAD, with mild stenosisBack to article page
