Intraspinal canal platform system for coil embolization of anterior spinal artery aneurysm associated with spinal cord arteriovenous malformation: a case report and literature review

Letter: Combined Transradial and Transfemoral Approach Using a Compliant Balloon for Emboli Protection at the Vertebral Artery During Subclavian Stenosis Stenting: 2-Dimensional Operative Video

“…We have employed transradial access as the first-line approach for neurointerventions. [2][3][4][5][6][7][8] We completely agree with the authors' conception that subclavian artery stenting using a combined transradial and transfemoral access with a duallumen compliant balloon catheter (Scepter XC; MicroVention, Aliso Viejo, California) is a useful therapeutic option for patients with symptomatic left proximal subclavian artery stenosis. The preprocedural angiography revealed severe left subclavian artery stenosis with an irregular shape and persisting antegrade flow in the left vertebral artery (VA) in this case.…”

Role of the Cervical Anterior Spinal Artery in the Endovascular Treatment of Vascular Diseases: Bystander, Accomplice, Victim, or Friend?

“…EVT for isolated ASA aneurysms remains difficult because the catheter system must be constructed via the small-caliber ASA ( 3 ). For flow-related aneurysms of the ASA, because the ASA is often dilated, EVT may be feasible ( 87 ).…”

“…The cervical anterior spinal artery (ASA) arises from the intracranial vertebral artery (VA) and provides blood to the anterior two-thirds of the spinal cord (1). It may be involved in many cervical spinal vascular diseases, such as arteriovenous fistula (AVF), arteriovenous malformation (AVM), and aneurysm (2)(3)(4). In addition, in VA occlusion or the subclavian steal phenomenon, the cervical ASA can serve as a collateral channel (5).…”

Letter: Transradial Flow-Diverting Stent Placement Through an Arteria Lusoria: 2-Dimensional Operative Video

“…4 Nevertheless, a guide catheter may result in a failed TRA that necessitates a crossover to transfemoral access because of a failed cannulation, a kinked catheter, or an unstable system.We have used transradial access as the first-line access for neurointerventions. [5][6][7][8][9][10][11][12][13][14][15][16][17][18] The first-line TRA using a 6F preshaped Simmons guiding sheath (outer diameter, 2.70 mm; inner diameter, 0.088 00 ; usable length, 90 cm; 6F Axcelguide Stiff-J; Medikit) offers a large bore working channel and a high procedural success rate without catheter kinking or system instability even in patients with an unfavorable steep supra-aortic take-off. [5][6][7]13 The 6F Simmons guiding sheath is fully engaged into the target common carotid artery with a pull-back maneuver (the pull-back technique) after reforming the Simmons curve within the ascending aorta.…”
