  "abstract": "Introduction Intracranial (IAD) and extracranial (EAD) artery dissection is a rare but important cause of ischemic stroke. Its management lacks standardization, usually relying on antithrombotic therapy. In cases of acute neurological symptoms, endovascular treatment is applied. While permanent stenting is widely practiced, it requires dual antiplatelet therapy (DAPT), which increases the risk of hemorrhagic complications, particularly in patients with large infarcts or concurrent SAH.Aim of Study To present six cases and evaluate the feasibility, safety, outcomes and highlight the potential of non-permanent stenting as an alternative treatment option for IAD/EAD with flow-limiting arterial stenosis.Method We included six cases of non-permanent stenting for IAD/EAD. All patients underwent pre- and postinterventional non-invasive angiographic imaging (CTA or MRA) and clinical evaluation (NIHSS score and mRS at 90 days was recorded). The endovascular technique involved deploying a stent retriever for recanalization, followed by glycoprotein IIb/IIIa infusion during deployment of the stent retriever. Stent retrievers were atraumatically retrieved at the end of the intervention.Results Successful vessel recanalization was achieved in the majority of cases (5/6, 83.3%), with one patient ultimately requiring a permanent stent. Follow-up imaging demonstrated resolution of the dissection without significant residual stenosis and without new ischemic events. Minor complications included two instances of self-limiting subarachnoid hemorrhage, no major bleeding or recurrent dissections were observed.Conclusion Non-permanent stenting using stent retrievers may represent a valuable addition to the therapeutic approaches for IAD/EAD, especially in patients with a high risk of intracranial hemorrhage under DAPT.Conflict of Interest No",
