Experimental Flow Studies in Carotid Artery Models Using Protecting Systems, e.g. Stents and Filters

摘要

Stroke is the most common and disabling neurological disorder. Carotid artery stenosis is a significant risk factor for stroke. Two kinds of therapy exist to improve the blood flow in the carotid arteries. Stenosis plaque is eliminated by surgical intervention (carotid endarterectomy). Endovascular treatment is a promising new alternative to the traditional surgical repair. The plaque is thrust aside by endovascular intervention. During percutaneous transluminal angioplasty and/or stenting, dislodged plaque particles can cause stroke. Embolic protection devices can prevent particles from being dislodged during carotid artery stenting. They are inserted distal to the target lesion before stenting.
