Cerebral angioplasty practice at major medical centers in the United States

Neuroradiology. 2000 Mar;42(3):218-20. doi: 10.1007/s002340050051.

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 directors 47 (42%) indicated that cerebral angioplasty was being performed at their center. The greatest experience is currently for angioplasty of post-subarachnoid hemorrhage vasospasm (mean 16 procedures performed) and the least experience for dilation of basilar artery atherosclerosis (mean five procedures performed). The reported stroke and/or death rate in centers performing angioplasty of the extracranial carotid system is 1.5 %. Comparisons with other medical specialties (e.g., cardiologists, neurologists, neurosurgeons) are necessary to determine the full scope of extracranial neurovascular procedures being performed and the corresponding complication rates.
