Proximal Stent Edge Dissection After LM PCI
Figure 3. Proximal stent edge dissection detected by OCT
OCT showed that although the dissection was within intima, the maximal arc was 95.7 degrees and longitudinal length was 3.4mm (Figure 3). The findings met the criteria for major dissection, therefore we considered an additional stent implantation (1,2). Another DES (3.0x23mm) was implanted into proximal LM covering the dissection with satisfactory angiographic result and no post-procedure complications (Figure 4).
