During an optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI) of a calcified left anterior descending artery (LAD), the distal tip of the OCT catheter got stuck, and forceful tugging on the catheter by the operator led to LAD stent deformation proximally across the overlap between the proximal and middle stents. The purpose of these images is to make the readers aware of the very real and serious risk of a stuck OCT catheter, especially while imaging distal coronary arteries and overlapping stents. Increasing the length of the over-the-wire segment and hydrophilic coating of the OCT catheter may also be explored with manufacturers to prevent this complication.
在对钙化的左前降支（LAD）进行光学相干断层扫描（OCT）引导的经皮冠状动脉介入治疗（PCI）过程中，OCT导管的远端尖端卡住了，术者用力拉扯导管导致LAD支架在近端跨近端和中间支架重叠处发生变形。这些图像的目的是让读者意识到OCT导管卡住这一非常现实且严重的风险，尤其是在对冠状动脉远端和重叠支架进行成像时。还可与制造商探讨增加OCT导管的导丝段长度和亲水涂层，以预防这种并发症。
