利用光学相干断层成像(OCT)三维重建可以更好地评价经皮冠状动脉介入治疗(PCI),尤其是像冠脉分叉病变这样复合病变的介入治疗。一般认为斑块推移是主血管介入后侧支损伤的主要发生机制,然而最近的血管内影像学研究发现,血管脊移位可能是导致侧支损伤的主要原因。在本病例中,在线三维OCT可为研究主干血管介入后血管脊移位对侧支病变的影响提供客观依据。从血流储备分数来看,(支架置入)术后,血管脊移位所致的侧支损伤并不一定是功能性损伤,这为PCI后侧支损伤血管造影评价结果与功能性评价结果不一致提供了合理解释。本病例报告说明OCT如何指导PCI以及如何利用三维OCT评估分叉损伤介入后侧支损伤的发生机制。也许将来有一天,我们能够在检验室利用OCT三维显像实时做出临床决策。
