Antegrade dissection re-entry is often discouraged for chronic total occlusions (CTOs) with a bifurcation at the distal cap due to risk of side branch occlusion that can lead to periprocedural myocardial infarction and incomplete revascularization. Antegrade dissection re-entry, however, is often needed, especially in complex cases. We present the novel "double Stingray technique" for CTOs involving bifurcations, in which the Stingray system is used twice for re-entry into both vessel branches, followed by two-stent bifurcation stenting to maintain the patency of both branches.
由于存在边支闭塞的风险，可能导致围手术期心肌梗死和不完全血运重建，对于远端帽处存在分叉的慢性完全闭塞病变（CTO），通常不鼓励采用顺行夹层再入技术。然而，顺行夹层再入技术往往是必要的，尤其是在复杂病例中。我们提出了一种针对涉及分叉的CTO的新型“双Stingray技术”，即在该技术中，Stingray系统被两次用于再入两个血管分支，随后进行双支架分叉支架置入术以维持两个分支的通畅。
