Stenting of the Stenotic Common Carotid Artery Ostium by the Buddy Wire Technique: A Case Report

抄録

Objective: A case in which carotid artery stenting (CAS) was performed via the femoral artery for stenosis of the left common carotid artery ostium is reported.

Case Presentation: The patient was a 70-year-old man with multiple infarction of the right cerebral hemisphere that presented with a transient decrease in grip strength and numbness of the left hand. Occlusion of the right internal carotid artery and stenosis of the left common carotid artery ostium were demonstrated. CAS was performed using the buddy wire technique and a distal filter protection device for stenosis of the left common carotid artery ostium. The postoperative course was uneventful, and the patient was discharged to home 8 days after surgery.

Conclusion: In CAS for stenotic lesions of the common carotid artery ostium, the concomitant use of the buddy wire technique is useful.
