Background It is often hard to navigate a 9 French (F) balloon guiding catheter in patients with type III or bovine aortic arch. Also, a common carotid artery stenosis is challenging, because a guidewire cannot be advanced distally. We developed the combination of a 4F Simmons-type catheter and a 6F distal access catheter as a coaxial inner catheter to navigate a 9F balloon guiding catheter to overcome these difficulties. Materials and methods Medical record at our institution was retrospectively reviewed and carotid artery stenting cases in which the 4F Simmons-6F distal access catheter system was employed as a coaxial catheter to navigate a 9F balloon guiding catheter were identified. To construct this system, a 4F 145 cm SY3 (Hanako Medical, Saitama, Japan) and a 6F 118 cm Cerulean DD6 (Medikit Co. Ltd., Tokyo, Japan) were usually employed. A rotating hemostatic valve should be as short as possible and was attached to only a 9F balloon guiding catheter. The length of a 0.035-in. guidewire needed to be 180 cm or longer. Results During the study period, 106 carotid artery stenting cases were identified. Of these, this system was employed in 29 cases that included 5 cases with a steno-occlusive lesion at common carotid artery/external carotid artery, 10 with type III or bovine arch, and 11 harboring both. In all the cases, a 9F balloon guiding catheter was successfully navigated. Conclusion The 4F Simmons-6F distal access catheter system was useful in navigating a 9F balloon guiding catheter in patients with a common carotid artery stenosis, an external carotid artery occlusion, and an in-stent restenosis, especially when they also harbored type III or bovine aortic arch.

Background and purpose Placement of a large-bore guiding sheath or catheter into the common carotid artery (CCA) is crucial in transbrachial carotid artery stenting (CAS). Herein, we describe technical tips for the navigation of a 6-French guiding sheath into the CCA using a tri-axial catheter system in transbrachial CAS. Materials and methods A total of 27 patients underwent transbrachial CAS. For the right side, a 6-French straight guiding sheath was navigated directly into the CCA using a tri-axial catheter system, with a 4-French Simmons catheter placed through a 6-French straight guiding catheter. For the left side, a 6-French Simmons guiding sheath was navigated into the CCA using a tri-axial catheter system, with a 4-French Simmons catheter placed through a 6-French Simmons guiding catheter. After the placement of a 6-French guiding sheath into the CCA, CAS was performed under distal filter or balloon protection. Results Fifteen patients had a right carotid stenosis and 12 patients had a left carotid stenosis. The 6-French guiding sheath was safely placed with ease and provided adequate stabilization for CAS. All procedures were successfully performed without any complications. Conclusion The use of a tri-axial catheter system for the navigation of a 6-French guiding sheath into the CCA appears safe and efficient, allowing transbrachial CAS, with 6-French guiding sheath stabilization, to be performed without any complication.

Objective This study was performed to explore the effect of the aortic arch type on technical indicators in patients undergoing carotid artery stenting (CAS). Methods The data of 224 consecutive patients who underwent unilateral CAS from January 2011 to December 2012 were retrospectively analyzed. The requirement for placement of the guiding catheter into the common carotid artery with assistance of an angiographic catheter, fluoroscopy time, contrast agent dose, and adverse events were recorded. Results The fluoroscopy time was significantly longer and the contrast agent dose was significantly higher in patients with Type III than Type I and II arches. Significantly more patients with Type III than Type I and II arches required placement of the guiding catheter with assistance of an angiographic catheter (46.2% vs. 15.0%, respectively). The procedural success rate was significantly lower in patients with Type III than Type I and II arches (96.2% vs. 100.0%, respectively). The incidence of death, myocardial infarction, and all types of stroke was significantly higher in patients with Type III than Type I and II arches (7.7% vs. 1.7%, respectively). Conclusions The aortic arch type is an important influential factor in CAS. Type III arches are associated with more difficulties and complications.

A 54-year-old man with symptomatic internal carotid artery stenosis with absence of the common carotid artery (CCA), who had been treated with surgery and postoperative radiotherapy for tonsillar carcinoma, underwent direct percutaneous carotid artery stenting (CAS). To our knowledge, this is the first report of direct percutaneous carotid artery stenting (CAS) for a patient with absent CCA.
