[Stent implantation into the basilar artery for supporting endovascular aneurysm treatment].
In aneurysms with a neck:dome ratio of 1:2 or more or with a wide neck, endovascular treatment is less effective. In this situation, the rate of thrombotic and thromboembolic complications is increased. Recently available highly flexible balloon expandable coronary stents improved the technique of endovascular aneurysm treatment. Two patients with wide neck midbasilar aneurysms were successfully treated endovascularly using a combination of stent deployment into the basilar artery and coil occlusion of the aneurysm. The creation of an artificial boundary between a side wall aneurysm and the parent artery by stent deployment improves the conditions for subsequent coil occlusion of the aneurysm. If, after detachment, coils protrude from the lumen of a side wall aneurysm into the parent vessel, stenting of this vessel can prevent thrombotic and thromboembolic complications.
