Abstract
The transfemoral approach is a common technique for carotid artery stenting(CAS)and involves the risk of distal embolism when a high-grade stenosis occurs at the common carotid artery(CCA). In this study, to minimize the risk of thromboembolic complications, we used a guide sheath that was specifically designed for direct cannulation to the CCA without the use of a guidewire or coaxial catheter. This study included 5 patients who underwent CAS of the CCA by using a guide sheath. Of these patients, 2 had right CCA stenosis and the other 3 had left CCA lesions. In all cases, direct cannulation to the target CCA by using the guide sheath was achieved, and CAS was performed safely. The median time from puncture to the end of the procedure was 61 min(interquartile range: 53-63). No periprocedural complications or cardiovascular events occurred within 30 days after CAS. CAS was safely and successfully performed for CCA stenosis by using the transbrachial guide sheath that was specifically designed for direct cannulation to the CCA.
