Excerpt
Endovascular therapy for stenosis at the origin of the common carotid artery (CCA) poses a technical challenge [
1]. Treatments that have been described for this condition include open retrograde stenting [
2‐
5] and percutaneous antegrade stenting [
1,
6‐
11]. Open retrograde stenting can stabilize the catheter system and facilitate accurate stent placement. Moreover, surgical clamping of the distal CCA can prevent procedure-related cerebral embolism. However, this method is more invasive and complex than the percutaneous approach [
12] and carries risks of postoperative cervical hematoma, arterial dissection, infection, and cranial nerve injury [
2,
13]. Percutaneous antegrade stenting for such stenosis is technically difficult because the guiding system lacks adequate catheter backup support [
1,
14]. To date, methods of cerebral embolic protection have not been well investigated. …
