Neuroradiology. 2023 Dec;65(12):1803-1807. doi: 10.1007/s00234-023-03239-1. Epub 2023 Oct 16.

Abstract

We present a case of ultra-early symptomatic fish-mouth type stenosis (FMTS) of a Surpass Evolve flow diverter stent (SE-FDS) occurring within 24 h after deployment for the treatment of multiple unruptured right siphon aneurysms in a 44-year-old patient. The patient developed left hemiplegia and hemineglect, and was treated with mechanical thrombectomy (MT) and Tirofiban infusion. This is the first report of an ultra-early FMTS with a SE-FDS and its mechanism is discussed in the light of available data in the literature.

Keywords: Complication; Fish-mouth type stenosis; Flow diverter; Stent.
