Topic: Advantage of IVUS using in DCB era


During the past decade, various types of scaffold, such as drug eluting stent, interwoven stent, and stent-graft, have become available in the field of endovascular therapy (EVT) for femoro-popliteal (FP) lesion. Compared to conventional plain old balloon angioplasty, EVT with those devices have achieved better long-term patency, hence have brought clinical benefit to patients with lower extremity artery disease (LEAD). However, the risk of restenosis can’t be avoided in scaffold-assisted EVT, especially in small vessels or heavily
calcified lesions.
Drug coated balloons (DCBs) have been introduced in early 2010s to compensate these dilemmas and have been frequently used in our daily practice. In combination with various types of atherectomy devices, the indication of DCB use have become more diverse, enabling the shift of therapeutic strategies to “leave nothing behind” procedure.
Intra vascular ultrasound (IVUS) gives clear sectional image of the vessel, adding more detailed information to the angiographic findings. Not only for the safer procedure, IVUS guided procedure plays an important role in more efficient procedure by offering
abovementioned detailed information of target lesion. Vessel preparation, selection of finalizing device, and precise evaluation of healthy zone are key issues that we should obtain from IVUS.
I look forward to sharing the latest clinical data of DCB application in Japan, focusing the
advantage of IVUS-guided EVT with all attendees in this meeting.
