Abstract
OBJECTIVE To review our multi-institutional experience with endovascular therapy for right subclavian artery occlusive disease and to evaluate the long-term outcomes. METHODS We retrospectively evaluated all patients with right subclavian artery stenosis and occlusive disease who underwent endovascular therapy between March 2014 and September 2022 at two institutions. Patient baseline demographics, lesion characteristics, treatment strategies, and in-hospital and follow-up outcomes were prospectively collected and retrospectively analyzed. RESULTS Between March 2014 and September 2022, 73 patients underwent endovascular treatment at the two institutions. The dominant cause of lesions in this cohort was atherosclerosis. Three different types of lesions were summarized, and the corresponding endovascular strategies were performed. 66 patients (90.4%) underwent successful endovascular treatment, and 62 patients (84.9%) underwent balloon-expandable stent deployment. The mean perioperative in-hospital stay was 4.0 days (range, 3-6 days). Two patients died due to myocardial infarction, and one died of cerebral hemorrhage resulting from a traffic accident within 30 days of the intervention. The median follow-up time was 31.6 months (range, 12-96 months). No complications, including death, stroke, stent fractures, or migration, were noted in any patient during the follow-up period. The overall complication rate was 7/73 (9.6%), and 5/7 (6.9%) of the complications required reintervention. CONCLUSIONS Endovascular treatment of right subclavian artery lesions is safe, effective, and technically achievable. The reasonable use of balloon-expandable stents can achieve satisfactory outcomes with accurate orientation and promising patency.

Transradial dual-balloon protection system for subclavian artery stenting: "Balloon Switching" technique and literature review. Eur J Radiol 2021; 143:109907. [PMID: 34438329 DOI: 10.1016/j.ejrad.2021.109907] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Revised: 07/26/2021] [Accepted: 08/09/2021] [Indexed: 11/23/2022]
Abstract
PURPOSE Endovascular treatment for subclavian artery (SA) occlusive disease is well established; however, a potential risk remains for posterior circulation embolism, which can be life threatening. To reduce the risk of vertebral artery (VA) embolism, we have devised a transradial dual-balloon protection system referred to as the balloon switching technique. Herein, we describe a patient with left SA stenosis who successfully underwent SA stenting using the balloon switching technique. Case presentation A 79-year-old woman with left arm claudication was diagnosed with left subclavian steal syndrome due to severe stenosis of the proximal left SA. Endovascular revascularization using the balloon switching technique was employed. To obtain VA embolic protection during device advancement through the SA lesion, an 8F balloon-guiding catheter was inflated in the left SA at the level of the VA takeoff using the left transradial sheathless approach. A balloon-expandable stent was inflated in the SA lesion, followed by deflation of the balloon-guiding catheter. The stagnant left VA flow was flushed away toward the distal left SA. Following reinflation of the balloon-guiding catheter, the stent delivery system was deflated and removed. Floating debris in the SA proximal to the balloon-guiding catheter was adequately aspirated, followed by deflation of the balloon-guiding catheter. Left SA angiography showed successful revascularization, and postprocedural neuroimaging showed no evidence of ischemic stroke. CONCLUSIONS The balloon switching technique reduces the risk of VA embolism during left SA stenting via the transradial access. This method is a useful therapeutic option for patients with left SA occlusive disease.

Abstract
Endovascular intervention has become the mainstay of treatment for subclavian artery stenosis in many centers, with high technical success and low complication rates.1,2 However, potential embolization during proximal subclavian artery intervention can lead to catastrophic posterior circulation ischemic complications.3-5 Although considered a rare complication, the presence of a contralateral hypoplastic vertebral artery with persisting anterograde vertebral blood flow on the affected side is likely to increase the risk of embolization.3 The use of embolic protection devices, such as filters and noncompliant balloons, has been previously described.3,6,7 However, there is still a risk of distal embolization and vessel injury with the use of these devices.7 We present a technical video of a patient in their 80s with left subclavian stenosis who underwent subclavian stent-assisted percutaneous transluminal angioplasty (SAPTA) using an anterograde-retrograde access technique with a dual-lumen compliant balloon catheter (Scepter XC; MicroVention, Aliso Viejo, California) placed at the proximal segment of the left vertebral artery. With this approach, the compliant balloon provides adequate protection while minimizing the risk of endothelial injury and distal embolization. Written informed consent was obtained for the procedure. Patient consent was waived because all health information was deidentified.

Combined Transradial and Transfemoral Approach With Ostial Vertebral Balloon Protection for the Treatment of Patients With Subclavian Steal Syndrome. Front Neurol 2020; 11:576383. [PMID: 33193028 PMCID: PMC7642489 DOI: 10.3389/fneur.2020.576383] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Accepted: 09/11/2020] [Indexed: 01/10/2023] Open
Abstract
Background: Patients with an obstructive subclavian artery (SA) may exhibit symptoms of vertebrobasilar insufficiency known as subclavian steal syndrome (SSS). Endovascular treatment with stent assisted percutaneous transluminal angioplasty (SAPTA) demonstrates significantly lower percentage of intraoperative and postoperative complications in comparison with open surgery. There is a 1–5% risk of distal intracranial embolization through the ipsilateral vertebral artery (VA) during SAPTA. Objective: To assess the safety and feasibility of a novel technique for distal embolic protection using balloon catheters during SA revascularization with a dual transfemoral and transradial access. Methods: We describe a case series of patients with SSS who underwent SAPTA due to severe stenosis or occlusion of the SA using a combined anterograde/retrograde approach. Transfemoral access to SA was obtained using large bore guide sheaths. Ipsilateral transradial access was obtained using intermediate bore catheters. A Scepter XC balloon catheter was introduced through the transradial intermediate catheter into the ipsilateral VA at the ostium during SAPTA for distal embolic protection. Results: A total of eight patients with SSS underwent subclavian SAPTA. Four patients had the combined anterograde/retrograde approach. Successful revascularization was achieved in three of them. It was difficult to create a channel in the fourth unsuccessful case due to heavily calcified plaque burden. No peri-operative ischemic events were identified. On follow-up, we demonstrated patency of the stents with resolution of symptoms and without any adverse events. Conclusion: Subclavian stenting using a combined transradial and transfemoral access with compliant balloon catheters at the vertebral ostium for prevention of distal emboli may represent an alternative therapeutic approach for the treatment of SA stenosis and occlusions.
