The application of Chaperon guiding catheter system in endovascular treatment of intracranial aneurysms / 介入放射学杂志

ABSTRACT

Objective To discuss the application of Chaperon guiding catheter system in endovascular treatment of intracranial aneurysms. Methods A total of 20 patients with intracranial aneurysms were enrolled in this study. The patients hadⅡorⅢtype of aortic arch (n=11) or sclerotic plague at the orifice of internal carotid or vertebral artery (n = 9). Endovascular embolization of the intracranial aneurysm was carried out in all patients. By using Cordis guiding catheter system the catheter was placed into the target artery. Chaperon guiding catheter system was used during the procedure in order to determine whether the Chaperon guiding catheter could be smoothly placed into the target artery or not. Results When the Chaperon guiding catheter system was employed in the endovascular procedure, the difficulties of catheterization caused by the distortion of the aorta or by the plagues on the walls of arteries could be basically overcome. The Guiding catheter could be smoothly placed into the target arteries. Conclusion The Chaperon guiding catheter system can be successfully used in the endovascular treatment for the intracranial aneurysms, especially when the patient has tortuous aorta or there is sclerotic plague on the artery wall.
