Abstract

Orbital atherectomy (OA) may be effective in managing undilatable in-stent restenosis (ISR) despite off-label indications. We demonstrated that optical frequency domain imaging (OFDI)-guided OA, with a guide-extension system was effective even in distally located, undilatable ISR. However, OFDI revealed that inter-struts calcified neoatherosclerosis remained a challenging issue.

摘要

尽管存在未获批准的适应症，但眼眶动脉粥样硬化切除术（OA）可能对治疗不可扩张的支架内再狭窄（ISR）有效。我们证明，使用引导延伸系统的光学频域成像（OFDI）引导下的OA即使对位于远端的、不可扩张的ISR也有效。然而，OFDI显示支架小梁间钙化性新动脉粥样硬化仍然是一个具有挑战性的问题。
