Recurrent reversible in-stent-stenosis after flow diverter treatment
Flow diverter stents (FDS) are well established in the treatment of intracranial aneurysms which are difcult to treat with
conventional endovascular techniques. However, they carry a relatively high risk of specifc complications compared to
conventional stents. A minor but frequent fnding is the occurrence of reversible in-stent-stenosis (ISS) that tend to resolve
spontaneously over time. Here, we report the case of a patient in their 30s who was treated with FDS for bilateral paraophthalmic internal carotid artery (ICA) aneurysms. ISS were found at the respective early follow-up examinations on both sides and
had resolved at the 1-year follow-up examinations. Surprisingly ISS reoccurred at both sides in later follow-up examinations
and again resolved spontaneously. The recurrence of ISS after resolution is a fnding that has not been described previously.
Its incidence and further development should be investigated systematically. This might contribute to our understanding of
the mechanisms underlying the efect of FDS
