A breakthrough trans-collateral retrograde access for occlusive superficial femoral artery: multi-site access and sheaths insertion (MUSASHI) technique

A purpose of this article is to describe a breakthrough technique for occlusive superficial femoral artery (SFA) recanalization: multi-site access and sheaths insertion (MUSASHI) technique. Trans-collateral retrograde approach (TCA) for SFA cannot become popular because it needs conventional (crossover or ipsilateral) approach, which might not be suitable for collateral channel tracking. An innovative MUSASHI technique has a possibility to make TCA popular. Inserting two different sheaths into SFA and profunda artery from common femoral artery, we can manipulate both antegrade and retrograde guidewires without losing their trackability and with strong system-stability. Using MUSASHI technique, TCA may become easier and safer.
