The features of the use of flow-directing and braided stents with flow-directing properties in the occlusion of intracranial aneurysms of small diameter arteries have been determined. The effectiveness and safety of using flow-directing and braided stents with flow-directing properties in patients with small-diameter artery aneurysms were analyzed. It has been established that the width of the neck, the location of the aneurysm, and the origin of the perforating arteries are key factors determining the choice of stent type. Braided stents have a lower mesh density, which allows for maintaining blood flow in perforating arteries, so implantation at the level of perforating arteries should be preferred to these stents. In tortuous vascular areas, the choice of a flexible protective stent with an adaptive structure is crucial. A wide aneurysm neck contributes to residual blood flow in the aneurysm, even if a protective stent has been successfully implanted, so if other anatomical features of the artery segment hosting a wide-necked aneurysm allow, flow-guiding stents should be preferred. In tortuous vessels, the use of rigid stents may cause deformation of the vessel or stent, which reduces the effectiveness of aneurysm occlusion, so in such cases, preference should be given to flexible stents that can adapt to the shape without losing stability. Balloon stent expansion technique should be used to facilitate stent positioning and adaptation. No difference in end results was found between stents. Effectiveness: Increased effectiveness of treatment of patients with intracranial aneurysms of small diameter arteries who were operated on using flow-guiding stents and braided stents with flow-guiding properties.
