Kissing intravascular lithotripsy in iliac in-stent restenosis related to underexpanded stents.

ABSTRACT

Intravascular lithotripsy (IVL) has been used for the treatment of native highly calcified arterial lesions. No data are available in the literature about its use in the treatment of noncoronary in-stent restenosis (ISR). We report the case of kissing IVL in highly calcified iliac ISR related to underexpansion of stents previously deployed in the common iliac arteries. The procedures were performed with a combined percutaneous right femoral and surgical left axillary access. This case demonstrates the safety and effectiveness of IVL even for the treatment of iliac ISR when other "standard" techniques cannot be used to obtain a satisfactory outcome. This technique needs to be evaluated further with multicenter experiences and adequate population sizes.
