Although the transbrachial artery approach has been well described as an alternative for percutaneous coronary interventions and diagnostic cerebral arteriography, little has been reported regarding the use of this technique for therapeutic neuroendovascular procedures. We highlight the technical applications of this technique during 5 procedures. Three women (age 68, 69, and 83 years) and 1 man (age 79 years) were treated using brachial artery access. Two of the women with complex posterior circulation aneurysms were treated with stent-assisted coil embolization. The third woman presented with a symptomatic occlusion of the basilar artery and underwent intra-arterial thrombolysis and angioplasty, followed at a later date by a second intra-arterial thrombolysis procedure. The male patient presented with recurrent, intractable posterior circulation ischemic events and underwent balloon angioplasty and stenting of a high-grade stenosis of the right vertebral artery. All patients had failed treatment via a transfemoral route and demonstrated significant thoracoaortic and/or iliofemoral tortuosity. Appropriate intracranial vascular access was achieved in all patients, and there were no intraprocedural complications. We conclude that a transbrachial approach may be successfully used for a variety of therapeutic neuroendovascular interventions when a transfemoral route is not available.

Patient 1

A 68-year-old woman presented with a history of subarachnoid hemorrhage due to rupture of a vertebrobasilar junction aneurysm. She had been treated initially at another institution with endovascular coil embolization, but suffered 2 recurrences of the aneurysm, due at least in part to an associated left subclavian artery occlusion and subclavian steal flow pattern, leading to retrograde flow in the left vertebral artery (VA). The left subclavian artery was opened with a stent before the second

Discussion

The standard transfemoral approach for vascular access cannot be used in an estimated 2%-10% of patients requiring selective cerebral angiography.1, 8, 9 Neuroendovascular examination and treatment by this route may be technically challenging or even impossible in patients with severe aortoiliac disease, history of iliofemoral bypass graft placement, aberrant aortic arch anatomy, or morbid obesity.10, 11, 12 Furthermore, as recent advances in endovascular techniques have expanded the scope of
