Cerebral angioplasty practice at major medical centers in the United States

Abstract: Concern has been expressed recently regarding the proliferation of angioplasty and/or stenting of cerebral vessels. However, little is known about the volume of angioplasties being performed or the number of experienced interventionalists. A questionnaire was mailed to directors of accredited radiology residency programs in the United States, to define the level of expertise available at teaching hospitals in terms of angioplasty and/or stenting. Of 200 programs surveyed, 111 responded (56 %). Of 111 program d… Show more

“…3 Furthermore, the risk for subsequent stroke in the territory of the stenotic artery is 23% at 1 year and 25% at 2 years in patients with severe stenosis of 70% or more. [3][4][5] Although successful intracranial artery angioplasty has been attempted, [6][7][8][9] the efficacy of angioplasty alone seems limited because of early elastic arterial recoil and the chronic, geometric arterial changes caused by the negative remodeling leading to restenosis. 10,11 The recent advent of new-generation stents with a low profile and high flexibility has allowed stentassisted angioplasty to be considered as an alternative approach for the treatment of intracranial stenosis.…”

“…Intracranial angioplasty and stent-assisted angioplasty for intracranial atherosclerosis are fairly new procedures and even at tertiary referral centers, the number of treated cases annually is small in relation to other neurointerventional procedures, for example, extracranial carotid stenting. 71 Currently, there is no widely accepted credentialing procedure specific to intracranial angioplasty or stent-assisted angioplasty comparable to endovascularization procedures for extracranial carotid arteries used in clinical trials. [72][73][74] In a recent joint statement from the American Academy of Neurology, the American Association of Neurological Surgeons, the American Society of Interventional and Therapeutic Neuroradiology, the American Society of Neuroradiology, the Congress of Neurological Surgeons, the American Association of Neurological Surgeons/Congress of Neurological Surgeons Cerebrovascular Section, and the Society of Interventional Radiology, the requirement of a defined formal training and experience in both the cognitive and technical aspects of the neurosciences for the performance and interpretation of diagnostic and therapeutic cervical and cerebrovascular procedures was deemed essential.…”
