Abstract

Flow diverters (FDs) are an established treatment method for dissecting aneurysms.^{1Liu J.M., Zhou Y., Li Y., Li T., Leng B., Zhang P., y al. Parent artery reconstruction for large or giant cerebral aneurysms using the tubridge flow diverter: a multicenter, randomized, controlled clinical trial (PARAT) AJNR Am J Neuroradiol 2018 ; 39 (5) : 807-816 [cross-ref]

In this procedure, we successfully advanced a microwire-guided microcatheter through the proximal portion of the compromised stent. Utilizing an exchange technique, the original delivery catheter was replaced to facilitate deployment of a Lattice flow diverter. Final angiography confirmed adequate overlap between the two stents with re-established luminal patency in the parent artery. n analogous clinical scenarios, telescoping stent deployment within the shortened endoprosthesis may constitute a viable salvage strategy.
